  1. The IFR pyroprocessing for high-level waste minimization

    1993-01-01

    The process developed for the recycle of integral fast reactor (IFR) spent fuel utilizes a combination of pyrometallurgical and electrochemical methods and has been termed pyroprocessing. The process has been operated at full scale with simulated spent fuel using nonradioactive fission product elements. A comprehensive demonstration of the pyroprocessing of irradiated IFR fuel will begin later this year. Pyroprocessing involves the anodic dissolution of all the constituent elements of the IFR spent fuel and controlled electrotransport (electrorefining) to separate the actinide elements from the fission products present in the spent fuel. The process be applied to the processing of spent light water reactor (LWR) fuel as well, requiring only the addition of a reduction step to convert the LWR fuel as well, requiring only the addition of a reduction step to convert the LWR oxide fuel to metallic form and a separation step to separate uranium from the transuranic (TRU) elements. The TRU elements are then recovered by electroefining in the same manner as the actinides from the IFR high-level wastes arising from pyroprocessing are virtually free of actinides, and the volume of the wastes is minimized by the intrinsic characteristics of the processing of the processing method

    The Integral Fast Reactor (IFR) fuel cycle is based on the use of a metallic fuel alloy, with nominal composition U-2OPu-lOZr. In its present state of development, this fuel system offers excellent high-burnup capabilities. Test fuel has been carried to burnups in excess of 20 atom % in EBR-II irradiations, and to peak burnups over 15 atom % in FFTF. The metallic fuel possesses physical characteristics, in particular very high thermal conductivity, that facilitate a high degree of passive inherent safety in the IFR design. The fuel has been shown to provide very large margins to failure in overpower transient events. Rapid overpower transient tests carried out in the TREAT reactor have shown the capability to withstand up to 400% overpower conditions before failing. An operational transient test conducted in EBR-II at a power ramp rate of 0.1% per second reached its termination point of 130% of normal power without any fuel failures. The IFR metallic fuel also exhibits superior compatibility with the liquid sodium coolant. Equally as important as the performance advantages offered by the use of metallic fuel is the fact that this fuel system permits the use of an innovative reprocessing method, known as ''pyroprocessing,'' featuring fused-salt electrorefining of the spent fuel. Development of the IFR pyroprocess has been underway at the Argonne National Laboratory for over five years, and great progress has been made toward establishing a commercially-viable process. Pyroprocessing offers a simple, compact means for closure of the fuel cycle, with anticipated significant savings in fuel cycle costs

    1991-01-01

    Pyroprocessing, as incorporated in the Integral Fast Reactor (IFR) program, is being developed as a resource-efficient means of providing fuel for a reactor which has outstanding safety characteristics and performance potential. This process has been shown to be an effective way to partition uranium, transuranic elements, and fissions products. Being a gross separation process, it is not compatible with production of pure plutonium, but permits the recycle of essentially all the transuranic material to the Integral Fast Reactor for consumption. Whether this process can also significantly simplify the LWR waste disposal problem depends on the outcome of process development -- estimated to take five years, and of the subsequent applications development programs. If successful, this program could influence the ultimate waste loading of the first repository and modify the requirements for a second repository. This document, discusses the possibility of pyroprocessing being utilized in waste management strategies

    This paper addresses the important safety considerations related to the unique Integral Fast Reactor (IFR) fuel cycle technology, the pyroprocess. Argonne has been developing the IFR since 1984. It is a liquid metal cooled reactor, with a unique metal alloy fuel, and it utilizes a radically new fuel cycle. An existing facility, the Hot Fuel Examination Facility-South (HFEF/S) is being modified and equipped to provide a complete demonstration of the fuel cycle. This paper will concentrate on safety aspects of the future HFEF/S operation, slated to begin late next year. HFEF/S is part of Argonne's complex of reactor test facilities located on the Idaho National Engineering Laboratory. HFEF/S was originally put into operation in 1964 as the EBR-II Fuel Cycle Facility (FCF) (Stevenson, 1987). From 1964--69 FCF operated to demonstrate an earlier and incomplete form of today's pyroprocess, recycling some 400 fuel assemblies back to EBR-II. The FCF mission was then changed to one of an irradiated fuels and materials examination facility, hence the name change to HFEF/S. The modifications consist of activities to bring the facility into conformance with today's much more stringent safety standards, and, of course, providing the new process equipment. The pyroprocess and the modifications themselves are described more fully elsewhere (Lineberry, 1987; Chang, 1987). 18 refs., 5 figs., 2 tabs

  5. Defining a metal-based waste form for IFR pyroprocessing wastes

    International Nuclear Information System (INIS)

    McDeavitt, S.M.; Park, J.Y.; Ackerman, J.P.

    1994-01-01

    Pyrochemical electrorefining to recover actinides from metal nuclear fuel is a key element of the Integral Fast Reactor (IFR) fuel cycle. The process separates the radioactive fission products from the long-lived actinides in a molten LiCl-KCl salt, and it generates a lower waste volume with significantly less long-term toxicity as compared to spent nuclear fuel. The process waste forms include a mineral-based waste form that will contain fission products removed from an electrolyte salt and a metal-based waste form that will contain metallic fission products and the fuel cladding and process materials. Two concepts for the metal-based waste form are being investigated: (1) encapsulating the metal constituents in a Cu-Al alloy and (2) alloying the metal constituents into a uniform stainless steel-based waste form. Results are given from our recent studies of these two concepts

  6. Actinide recycle potential in the IFR [Integral Fast Reactor

    Chang, Y.I.

    1989-01-01

    Rising concern about the greenhouse effect reinforces the need to reexamine the question of a next-generation reactor concept that can contribute significantly toward substitution for fossil-based energy generation. Even with only the nuclear capacity on-line today, world-wide reasonably assured uranium resources would last for only about 50 years. If nuclear is to make a significant contribution, breeding is a fundamental requirement. Uranium resources can then be extended by two orders of magnitude, making nuclear essentially a renewable energy source. The key technical elements of the IFR concept are metallic fuel and fuel cycle technology based on pyroprocessing. Pyroprocessing is radically different from the conventional PUREX reprocessing developed for the LWR oxide fuel. Chemical feasibility of pyroprocessing has been demonstrated. The next major step in the IFR development program will be the full-scale pyroprocessing demonstration to be carried out in conjunction with EBR-II. IFR fuel cycle closure based on pyroprocessing can also have a dramatic impact on the waste management options, and in particular on the actinide recycling. 6 figs

  7. Treatment of wastes in the Integral Fast Reactor (IFR) fuel cycle

    1997-01-01

    In both the reactor portion and the fuel-cycle portion of the Integral Fast Reactor (IFR), handling, treatment and disposal of wastes are simpler than in current fuel cycles. The vast majority (> 99.9%) of the very-long-lived radioactive TRU elements are not sent to the repository; rather, they are recycled. High-level waste volume from the IFR process (called ''the pyroprocess'') is lower than that from either the direct disposal of spent fuel or from conventional PUREX-type reprocessing. The quantity of low-level waste is very low. In the pyroprocess, the actinides are recovered and separated from the bulk of the fission products by an electrorefining step wherein the actinides are electrotransported from chopped fuel elements and deposited at cathodes. The volatile fission products xenon, krypton, and tritium are collected for long-term storage and decay. Zirconium and the ''noble metal'' fission products (those that are less easily oxidized than zirconium) remain in the anode compartment, to be removed with the fuel cladding fragments and made into a metal waste form. The remaining fission products collect in the salt as chlorides. A process has been developed to periodically remove the contaminated salt from the electrorefiner, separate most of the fission products, and return the purified salt in a form that is ready for continuing use. To clean up the electrorefiner salt, the fission products are removed by ion exchange onto a column of Zeolite A. After the purification step, the column material and the contained fission products are converted to a mineral waste form for disposal. The processes and equipment for waste isolation and conversion to suitable disposal forms are described in this paper. (author)

    The Integral Fast Reactor (IFR) fuel cycle holds promise for substantial improvements in economics, diversion-resistance, and waste management. This paper discusses technical features of the IFR fuel cycle, its technical progress, the development status, and the future plans and directions. The Integral Fast Reactor (IFR) fuel cycle, is based on the use of a metallic fuel alloy (U-Pu-Zr) that permits use of an innovative method for processing of spent fuel. This method, a combination of pyrometallurgical and electrochemical processes, has been termed pyroprocessing. It offers the advantages of a simple, compact processing system and limited volumes of stabilized high-level wastes. This translates to an economically viable system that is likely to receive favorable public response, particularly when combined with the other attributes of the Integral Fast Reactor. Substantial progress has been made in the development of the IFR pyroprocessing method. A comprehensive demonstration of the process will soon begin at the Argonne National Laboratory Idaho site, using spent fuel from the EBR-II reactor. An important advantage of the IFR is its ability to recycle fuel in the process of power generation, extending fuel resources by a considerable amount and assuring the continued viability of nuclear power stations by reducing dependence on external fuel supplies. Pyroprocessing is the means whereby the recycle process is accomplished. It can also be applied to the recovery of fuel constituents from spent fuel generated in the process of operation of conventional light water reactor power plants, offering the means to recover the valuable fuel resources remaining in that material

    In this study, characteristic of waste from pyro-processing which based on material balance FS v5.1 is evaluated for revising of A-KRS concept. To reduce volume and toxicity of PWR SNFs, the P and T Technology using pyro-processing and SFR is under development in KAERI. In accordance with this R and D, the A-KRS was developed by KAERI for disposal of waste from pyro-processing. After A-KRS concept development, material balance has been revised and characteristics of waste have been changed. To solve impending saturation of storage capacity of NPP sites, national policy on SNF management seems to be determined shortly. Demand on detailed analysis on impact of P and T using pyro-processing and SFR as base data is increasing. To compare direct disposal scenario to the P and T scenario using pyro-processing and SFR, updating of A-KRS reflecting amendment of material balance is required. In this study, characteristic of waste from pyro-processing which based on material balance FS v5.1 is evaluated. Every 15 types of outputs generated from pyro-processing are evaluated. Great reduction can be achieved by complete reuse of U/TRU/RE in SFR, because most of decay heat, radioactivity and radiotoxicity are generated from U/TRU/RE ingot. Within about 300 years, the fly ash filter containing Cs, Sr containing salt waste are important waste in perspective of decay heat and radioactivity. Importance of RE containing salt waste reduced. Management of hold-ups must be clarified because hold-ups take large portion of decay heat, radioactivity in the material balance FS v5.1

    1993-01-01

    The Integral Fast Reactor (IFR) fuel cycle features the use of an innovative reprocessing method, known as open-quotes pyroprocessingclose quotes featuring fused-salt electrofining of the spent fuel. Electrofining of IFR spent fuel involves uranium recovery by electro-transport to a solid steel cathode. The thermodynamics of the system preclude plutonium recovery in the same way, so a liquid cadmium cathode located in the electrolyte salt phase is utilized. The deposition of Pu, Am, Np, and Cm takes place at the liquid cadmium cathode in the form of cadmium intermetallic compounds (e.g, PuCd 6 ), and uranium deposits as the pure metal when cadmium saturation is reached. A small amount of rare earth fission products deposit together with the heavy metals at both the solid and liquid cadmium cathodes, providing a significant degree of self-protection. A full scope demonstration of the IFR fuel cycle will begin in 1993, using fuel irradiated in EBR-II

  20. Projected Salt Waste Production from a Commercial Pyroprocessing Facility

    2013-01-01

    Full Text Available Pyroprocessing of used nuclear fuel inevitably produces salt waste from electrorefining and/or oxide reduction unit operations. Various process design characteristics can affect the actual mass of such waste produced. This paper examines both oxide and metal fuel treatment, estimates the amount of salt waste generated, and assesses potential benefit of process options to mitigate the generation of salt waste. For reference purposes, a facility is considered in which 100 MT/year of fuel is processed. Salt waste estimates range from 8 to 20 MT/year from considering numerous scenarios. It appears that some benefit may be derived from advanced processes for separating fission products from molten salt waste, but the degree of improvement is limited. Waste form production is also considered but appears to be economically unfavorable. Direct disposal of salt into a salt basin type repository is found to be the most promising with respect to minimizing the impact of waste generation on the economic feasibility and sustainability of pyroprocessing.

    A metallic fuel alloy, nominally U-20Pu-10Zr, is the key element of the IFR fuel cycle. This metallic fuel permits the use of an innovative reprocessing method, known as ''pyoprocessing,'' featuring fused-salt electrorefining of the spent fuel. Electrorefining separates the actinide elements from fission products, without producing a separate stream of plutonium. The fuel product is contaminated with the higher actinides and with a minor amount of rare earth fission products, making it self-protecting and thus diversion-resistant while still perfectly suitable as a fuel material in the fast spectrum of the IFR core

    1992-01-01

    During the past few years Argonne National Laboratory has been developing the Integral Fast Reactor (IFR), an advanced liquid metal reactor. Much of the IFR technology stems from Argonne National Laboratory's experience with the Experimental Breeder Reactors, EBR 1 and 2. The unique aspect of EBR 2 is its success with high-burnup metallic fuel. Irradiation tests of the new U-Pu-Zr fuel for the IFR have now reached a burnup level of 20%. The results to date have demonstrated excellent performance characteristics of the metallic fuel in both steady-state and off-normal operating conditions. EBR 2 is now fully loaded with the IFR fuel alloys and fuel performance data are being generated. In turn, metallic fuel becomes the key factor in achieving a high degree of passive safety in the IFR. These characteristics were demonstrated dramatically by two landmark tests conducted at EBR 2 in 1986: loss of flow without scram; and loss of heat sink without scram. They demonstrated that the combination of high heat conductivity of metallic fuel and thermal inertia of the large sodium pool can shut the reactor down during potentially severe accidents without depending on human intervention or the operation of active engineered components. The IFR metallic fuel is also the key factor in compact pyroprocessing. Pyroprocessing uses high temperatures, molten salt and metal solvents to process metal fuels. The result is suitable for fabrication into new fuel elements. Feasibility studies are to be conducted into the recycling of actinides from light water reactor spent fuel in the IFR using the pyroprocessing approach to extract the actinides (author)

    A GoldSim template program for a safety assessment of a hybrid-typed repository system, called 'A-KRS', in which two kinds of pyro-processed radioactive wastes, low-level metal wastes and ceramic high-level wastes that arise from the pyro-processing of PWR nuclear spent fuels are disposed of, has been developed. This program is ready both for a deterministic and probabilistic total system performance assessment which is able to evaluate nuclide release from the repository and farther transport into the geosphere and biosphere under various normal, disruptive natural and manmade events, and scenarios. The A-KRS has been deterministically assessed with 5 various normal and abnormal scenarios associated with nuclide release and transport in and around the repository. Dose exposure rates to the farming exposure group have been evaluated in accordance with all the scenarios and then compared among other.

    Pyro-Process is now developing to retrieve reusable uranium and TRU, and to reduce the volume of high level waste from a nuclear power plant. In this situation, it is strongly required for the estimation of expected masses and their physical properties of the wastes. In this report, the amount of wastes and their physical properties are presupposed through some assumptions in regard to 10MTHM of Oxide Fuel with 4.5wt% U-235, 45,000 MWD/MTU, and 5yrs cooling. The produced wastes can be divided into three categories such as metal, CWF(Ceramic Waste Form), and VWF(Vitrified Waste Form). The 42 nuclrides in a spent nuclear fuel are distributed into the waste categories on the their physical and thermodynamic properties when they exist in metal, oxide, or chloride forms. The treated atomic groups are Uranium, TRU, Noble metal, Rare earth, Alkali metal, Halogens, and others. The mass of each waste is estimated by the distribution results. The off-gas waste is included into a CWF. The heat generations by the wastes in this Pyro-Process are calculated using a ORIGEN-ARP program. It is possible to estimate the amounts of wastes and their heat generation rates in this Pyro-Process analysis. These information are very helpful to design a waste container and its quantity also can be determined. The number of container and its heat generation rate will be key factor for the construction of interim storage facilities including a underground disposal site.

The A-KRS has been probabilistically assessed with 9 selected input parameters, each of which has its own statistical distribution for a normal release and transport scenario associated with nuclide release and transport in and around the repository. Probabilistic dose exposure rates to the farming exposure group have been evaluated. A sensitivity of 9 selected parameters to the result has also been investigated to see which parameter is more sensitive and important to the exposure rates.

  7. Actinide recycle potential in the Integral Fast Reactor (IFR) fuel cycle

    1990-01-01

    In the Integral Fast Reactor (IFR) development program, the entire reactor system -- reactor, fuel cycle, and waste process is being developed and optimized at the same time as a single integral entity. The use of metallic fuel in the IFR allows a radically improved fuel cycle technology. Pyroprocessing, which utilizes high temperatures and molten salt and molten metal solvents, can be advantageously utilized for processing metal fuels because the product is metal suitable for fabrication into new fuel elements. The key step in the IFR process is electrorefining, which provides for recovery of the valuable fuel constituents, uranium and plutonium, and for removal of fission products. In the electrorefining operation, uranium and plutonium are selectively transported from an anode to a cathode, leaving impurity elements, mainly fission products, either in the anode compartment or in a molten salt electrolyte. A notable feature of the IFR process is that the actinide elements accompany plutonium through the process. This results in a major advantage in the high-level waste management, because these actinides are automatically recycled back into the reactor for in-situ burning. Based on the recent IFR process development, a preliminary assessment has also been made to investigate the feasibility of further adapting the pyrochemical processes to directly extract actinides from LWR spent fuel. The results of this assessment indicate very promising potential and two most promising flowsheet options have been identified for further research and development. This paper also summarizes current thinking on the rationale for actinide recycle, its ramifications on the geologic repository and the current high-level waste management plans, and the necessary development programs. 5 refs., 4 figs., 4 tabs

    In this study, DGR concept for radioactive waste from pyro-processing of CANDU SNFs is developed. Identical material balance for PWR (MB 2.6.0) and mass ratio of radioactive nuclides to binding material for LiCl-KCl waste is applied to determine specification of waste form, packing/disposal canister. Optimum thermal dimensioning is estimated to be 40 m for disposal tunnel and 8 m for disposal hole pitch through ABAQUS thermal analyses. To reduce volume and toxicity of PWR SNFs, the P and T technology using pyro-processing and SFR is under development in KAERI. CANDU SNFs are not considered as a subject of P and T because of its low fissile content caused by use of natural uranium as a fuel material. However, contention that not only PWR SNFs but also CANDU SNFs must be re-used is raised constantly. To evaluate impact of application of P and T on CANDU SNFs in the perspective of disposal, DGR system concept for radioactive waste from pyroprocessing of CANDU SNFs based on material balance version 2.6.0 is developed in this study. The disposal area is expected to be about 20,800 m 2 for disposal of 842,000 CANDU fuel bundles.

    In this study, DGR concept for radioactive waste from pyro-processing of CANDU SNFs is developed. Identical material balance for PWR (MB 2.6.0) and mass ratio of radioactive nuclides to binding material for LiCl-KCl waste is applied to determine specification of waste form, packing/disposal canister. Optimum thermal dimensioning is estimated to be 40 m for disposal tunnel and 8 m for disposal hole pitch through ABAQUS thermal analyses. To reduce volume and toxicity of PWR SNFs, the P and T technology using pyro-processing and SFR is under development in KAERI. CANDU SNFs are not considered as a subject of P and T because of its low fissile content caused by use of natural uranium as a fuel material. However, contention that not only PWR SNFs but also CANDU SNFs must be re-used is raised constantly. To evaluate impact of application of P and T on CANDU SNFs in the perspective of disposal, DGR system concept for radioactive waste from pyroprocessing of CANDU SNFs based on material balance version 2.6.0 is developed in this study. The disposal area is expected to be about 20,800 m{sup 2} for disposal of 842,000 CANDU fuel bundles.

    Very recently, a GoldSim template program, GSTSPA, for a safety assessment of a conceptual hybrid-typed repository system, called 'A-KRS,' in which two kinds of pyroprocessed radioactive wastes, low-level metal wastes and ceramic high-level wastes that arise from the pyroprocessing of PWR nuclear spent fuels, has been developed and is to be disposed of by 'separate disposal' strategies. The A-KRS is considered to be constructed at two different depths in geological media: at a 200m depth, at which a possible human intrusion is considered to be limited after closure, for the pyroprocessed metal wastes with lower or no decay heat producing nuclides, and at a 500m depth, believed to be the reducing condition for nuclides with a rather higher radioactivity and heat generation rate. This program is ready for a probabilistic total system performance assessment (TSPA) which is able to evaluate nuclide release from the repository and farther transport into the geosphere and biosphere under various normal, disruptive natural and manmade events, and scenarios that can occur after a failure of a waste package and canister with associated uncertainty. To quantify the nuclide release and transport through the various possible pathways in the near- and far-fields of the A-KRS repository system under a normal groundwater flow scenario, some illustrative evaluations have been made through this study. Even though all parameter values associated with the A-KRS were assumed for the time being, the illustrative results should be informative since the evaluation of such releases is very important not only in view of the safety assessment of the repository, but also for design feedback of its performance

    A metallic fuel alloy, which is a key element of the IFR fuel cycle, permits the use of pyrochemical processing of the spent fuel. Electrorefining with molten salt electrolytes is a key step in the pyroprocess because the actinides are recovered, separated from the fission products present in the spent fuel in this operation and then recycled for use as fuel. Chemical and electrochemical aspects of the electrorefining method is to be described. (author)

    Since the early 2000s several template programs for the safety assessment of a high-level radioactive waste repository as well as a low- and intermediate level radioactive waste repository systems have been developed by utilizing GoldSim and AMBER at KAERI. Very recently, another template program for a conceptual hybrid-typed repository system, called 'A-KRS' in which two kinds of pyroprocessed radioactive wastes, low-level metal wastes and ceramic high-level wastes that arise from pyroprocessing of PWR nuclear spent fuels has been developed and are to be disposed of by separate disposal strategies.

    Highlights: > A geological disposal system consists of disposal overpacks, a buffer, and a deposition hole or a disposal tunnel for high-level wastes from a pyroprocessing of PWR spent fuels is proposed. The amount and characteristics of high-level wastes are analyzed based on the material balance of pyroprocessing. > Four kinds of deposition methods, two horizontal and two vertical, are proposed. Thermal design is carried out with ABAQUS program. The spacing between the disposal modules is determined for the peak temperature in buffer not to exceed 100 deg. C. > The effect of the double-layered buffer is compared with the traditional single-layered buffer in terms of disposal density. Also, the effect of cooling time (aging) is illustrated. > All the thermal calculations are represented by comparing the disposal area of PWR spent fuels with the same cooling time. - Abstract: The inventories of spent fuels are linearly dependent on the production of electricity generated by nuclear energy. Pyroprocessing of PWR spent fuels is one of promising technologies which can reduce the volume of spent fuels remarkably. The properties of high-level wastes from the pyroprocessing are totally different from those of spent fuels. A geological disposal system is proposed for the high-level wastes from pyroprocessing of spent fuels. The amount and characteristics of high-level wastes are analyzed based on the material balance of pyroprocessing. Around 665 kg of monazite ceramic wastes are expected from the pyroprocessing of 10 MtU of PWR spent fuels. Decay heat from monazite ceramic wastes is calculated using the ORIGEN-ARP program. Disposal modules consisting of storage cans, overpacks, and a deposition hole or a disposal tunnel are proposed. Four kinds of deposition methods are proposed. Thermal design is carried out with ABAQUS program and geological data obtained from the KAERI Underground Research Tunnel. Through the thermal analysis, the spacing between the disposal modules

    1993-01-01

    The pyrochemical electrorefining process for recovery of actinides in spent fuel from the Integral Fast Reactor accumulates fission product wastes as chlorides dissolved in molten LiCI-KCI and as metals, some of which are in molten cadmium. Pyrochemical processes are being developed to recover uranium and transuranium elements for return to the reactor, and to separate and immobilize fission products in suitable waste forms. Solvent cadmium is recycled within the process. Electrolyte salt is treated in a series of salt/cadmium extraction steps; it is also returned to the process. Salt-borne fission products are concentrated on a zeolite bed that is converted to a stable, leach-resistant mineral. Rare earth fission products from the salt, noble metal fission products, and cladding hulls are dispersed in a metal matrix

    The purpose of this project is to develop new high level waste (HLW) forms and fabrication processes to dispose of active metal fission products that are removed from electrorefiner salts in the pyroprocessing based fuel cycle. The current technology for disposing of active metal fission products in pyroprocessing involves non selectively discarding of fission product loaded salt in a glass-bonded sodalite ceramic waste form. Selective removal of fission products from the molten salt would greatly minimize the amount of HLW generated and methods were developed to achieve selective separation of fission products during a previous I NERI research project (I NERI 2006 002 K). This I NERI project proceeds from the previous project with the development of suitable waste forms to immobilize the separated fission products. The Korea Atomic Energy Research Institute (KAERI) has focused primarily on developing these waste forms using surrogate waste materials, while the Idaho National Laboratory (INL) has demonstrated fabrication of these waste forms using radioactive electrorefiner salts in hot cell facilities available at INL. Testing and characterization of these radioactive materials was also performed to determine the physical, chemical, and durability properties of the waste forms

    Pyroprocessing technology was developed in the beginning for metal fuel treatment in the US in the 1960s. The conventional aqueous process, such as PUREX, is not appropriate for treating metal fuel. Pyroprocessing technology has advantages over the aqueous process: less proliferation risk, treatment of spent fuel with relatively high heat and radioactivity, compact equipment, etc. The addition of an oxide reduction process to the pyroprocessing metal fuel treatment enables handling of oxide spent fuel, which draws a potential option for the management of spent fuel from the PWR. In this context, KAERI has been developing pyroprocessing technology to handle the oxide spent fuel since the 1990s. This paper describes the current status of pyroprocessing technology development at KAERI from the head-end process to the waste treatment. A unit process with various scales has been tested to produce the design data associated with the scale up. A performance test of unit processes integration will be conducted at the PRIDE facility, which will be constructed by early 2012. The PRIDE facility incorporates the unit processes all together in a cell with an Ar environment. The purpose of PRIDE is to test the processes for unit process performance, operability by remote equipment, the integrity of the unit processes, process monitoring, Ar environment system operation, and safeguards related activities. The test of PRIDE will be promising for further pyroprocessing technology development

    1991-01-01

    The fuel cycle of the Integral Fast Reactor (IFR) has important potential advantage for the management of high-level wastes. This sodium-cooled, fast reactor will use metal fuels that are reprocessed by pyrochemical methods to recover uranium, plutonium, and the minor actinides from spent core and blanket fuel. More than 99% of all transuranic (TRU) elements will be recovered and returned to the reactor, where they are efficiently burned. The pyrochemical processes being developed to treat the high-level process wastes are capable of producing waste forms with low TRU contents, which should be easier to dispose of. However, the IFR waste forms present new licensing issues because they will contain chloride salts and metal alloys rather than glass or ceramic. These fuel processing and waste treatment methods can also handle TRU-rich materials recovered from light-water reactors and offer the possibility of efficiently and productively consuming these fuel materials in future power reactors

    A new computational code package called PYRO has been developed to support the IFR fuel recycle demonstration project in the HFEF/S facility at ANL-W. The basic pyrochemical code PYRO1 1 models the atomic mass flows and phase compositions of 48 essential chemical elements involved in the pyroprocess. It has been extended to PYRO1 2 by linking with the ORIGEN code to track more than 1000 isotopic species, their radioactive decays, and related phenomena. This paper first describes the pyroprocess to be modeled and the pyrochemical capability that has been implemented in PYRO1 1 , and then gives a full account on the algorithm of extending it to PYRO1 2 for isotopic mass tracking. Results from several scoping and simulation runs will be discussed to illustrate the significance of modeling in process radioactive decays

    Modifications have begun to the Hot Fuel Examination Facility-South (HFEF/S) in order to demonstrate the technology of the integral fast reactor (IFR) fuel cycle. This paper describes the status of the modifications to the facility and briefly reviews the status of the development of the process equipment. The HFEF/S was the demonstration facility for the early Experimental Breeder Reactor II (EBR-II) melt refining/injection-casting fuel cycle. Then called the Fuel Cycle Facility, ∼400 EBR-II fuel assemblies were recycled in the two hot cells of the facility during the 1964-69 period. Since then it has been utilized as a fuels examination facility. The objective of the IFR fuel cycle program is to upgrade HFEF/S to current standards, install new process equipment, and demonstrate the commercial feasibility of the IFR pyroprocess fuel cycle

    The Integral Fast Reactor (IFR) fuel cycle holds promise for substantial improvements in economics, diversion-resistance, and waste management. In the IFR pyroprocessing, minor actinides accompany plutonium product stream, and therefore, actinide recycle occurs naturally. The fast neutron spectrum of the IFR makes it an ideal actinide burner, as well. This paper discusses technical features of the IFR fuel cycle, its technical progress, the development status, and potential implications on long-term waste management

    The Integral Fast Reactor (IFR) is being developed as a future commercial power source that promises to have important advantages over present reactors, including improved resource conservation and waste management. The spent metal alloy fuels from an IFR will be processed in an electrochemical cell operating at 500 degree C with a molten chloride salt electrolyte and cadmium metal anode. After the actinides have been recovered from several batches of core and blanket fuels, the salt cadmium in this electrorefiner will be treated to separate fission products from residual transuranic elements. This treatment produces a waste salt that contains the alkali metal, alkaline earth, and halide fission products; some of the rare earths; and less than 100 nCi/g of alpha activity. The treated metal wastes contain the rest of the fission products (except T, Kr, and Xe) small amounts of uranium, and only trace amounts of transuranic elements. The current concept for the salt waste form is an aluminosilicate matrix, and the concept for the metal waste form is a corrosion-resistant metal alloy. The processes and equipment being developed to treat and immobilize the salt and metal wastes are described

    1988-01-01

    Portland cement-base mortars are being considered for immobilizing chloride salt wastes produced by the fuel cycles of Integral Fast Reactors (IFR). The IFR is a sodium-cooled fast reactor with metal alloy fuels. It has a close-coupled fuel cycle in which fission products are separated from the actinides in an electrochemical cell operating at 500/degree/C. This cell has a liquid cadmium anode in which the fuels are dissolved and a liquid salt electrolyte. The salt will be a mixture of either lithium, potassium, and sodium chlorides or lithium, calcium, barium, and sodium chlorides. One method being considered for immobilizing the treated nontransuranic salt waste is to disperse the salt in a portland cement-base mortar that will be sealed in corrosion-resistant containers. For this application, the grout must be sufficiently fluid that it can be pumped into canister-molds where it will solidify into a strong, leach-resistant material. The set times must be longer than a few hours to allow sufficient time for processing, and the mortar must reach a reasonable compressive strength (/approximately/7 MPa) within three days to permit handling. Because fission product heating will be high, about 0.6 W/kg for a mortar containing 10% waste salt, the effects of elevated temperatures during curing and storage on mortar properties must be considered

    Korea Atomic Energy Research Institute (KAERI) has been developing a pyroproceesing technology to reduce the waste volume and recycle some elements. The pyroprocessing includes several treatment processes which are related with not only radiological and physical but also chemical and electrochemical properties. Thus, it is of importance to establish safety design requirements considering all the aspects of those properties for a reliable pyroprocessing facility. In this study, high-level requirements are presented in terms of not only radiation protection, nuclear criticality, fire protection, and seismic safety but also confinement and chemical safety for the unique characteristics of a pyroprocessing facility. Several high-level safety design requirements such as radiation protection, nuclear criticality, fire protection, seismic, confinement, and chemical processing were presented for a pyroprocessing facility. The requirements must fulfill domestic and international safety technology standards for a nuclear facility. Furthermore, additional requirements should be considered for the unique electrochemical treatments in a pyroprocessing facility.

    The chemical basis of Integral Fast Reactor fuel reprocessing (pyroprocessing) is partition of fuel, cladding, and fission product elements between molten LiCl-KCl and either a solid metal phase or a liquid cadmium phase. The partition reactions are described herein, and the thermodynamic basis for predicting distributions of actinides and fission products in the pyroprocess is discussed. The critical role of metal-phase activity coefficients, especially those of rare earth and the transuranic elements, is described. Measured separation factors, which are analogous to equilibrium constants but which involve concentrations rather than activities, are presented. The uses of thermodynamic calculations in process development are described, as are computer codes developed for calculating material flows and phase compositions in pyroprocessing

    A pyrochemical process is under development for recovering and recycling fuel discharged from the integral fast reactor (IFR). In the past year, two major changes have been made in this process. First, the halide slagging step previously used for concentrating plutonium bred in the blanket has been eliminated, not because it did not work but because the same purpose can be achieved by electrorefining. The current flow sheet is shown. Now, all of the necessary separations are achieved by electrorefining alone. Second, to make the electrorefining operations sufficiently flexible to provide the necessary separations while accommodating a range of feed compositions, two types of cathodes are employed. One is used for selective removal of uranium for recycle as blanket material, and the other is used for removal of a uranium-plutonium product for recycle as core material. Computer codes based on thermodynamic models have been developed to predict the fate of product elements (uranium and plutonium) and fission products. These show that high recovery of uranium and plutonium and adequate removal of fission products are achievable

    Typical molten salt separation is ANL-IFR pyroprocessing and ORNL-MSRE pyroprocessing. IFR pyroprocessing is based on Chloride chemistry and electrorefining. MSRE pyroprocessing is base on fluoride chemistry and reductive extraction. Major technologies of molten salt separation are electrorefining, electrowining, reductive extraction, and oxide reduction. Common characteristics of this technologies is to utilize reduction-oxidation phenomena in molten salt. Electrorefining process is modeled on the basis of diffusion layer theory and Butler-Volmor relation. This model is numerically solved by LSODA package. To acquire the technology of electrorefining process, 3-electrode electrochemical cell is developed where electrolyte is 500 degree C LiCl-KCl eutectic molten salt, working electrodes are Ni and Au, and reference electrode is Ag/AgCl. We have investigated the stable potential range using cyclic voltammogram of Ni electrode. We have measured steady state polarization curve of Ni electrode. Then corrosion potential of Ni electrode is -0.38V{sub Ag/AgCl} and corrosion current is 1.23 x 10{sup -4} A/cm{sup 2}. 12 refs., 6 tabs., 24 figs. (author)

    The fission product of rare earth (RE) oxide wastes are generates during the pyroprocess . Borosilicate glass or some ceramic materials such as monazite, apatite or sodium zirconium phosphate (NZP) have been a prospective host matrix through lots of experimental results. Silicate glasses have long been the preferred waste form for the immobilization of HLW. In immobilization of the RE oxides, the developed process on an industrial scale involves their incorporation into a glass matrix, by melting under 1200 ∼ 1300 .deg. C. Instead of the melting process, glass powder sintering is lower temperature (∼ 900 .deg. C) required for the process which implies less demanding conditions for the equipment and a less evaporation of volatile radionuclides. This study reports the behaviors, direct vitrification of RE oxides with glass frit, glass powder sintering of REceramic with glass frit, formation of RE-apatite (or REmonazite) ceramic according to reaction temperature, and the leach resistance of the solidified waste forms

  19. Technologies for destruction of long-lived radionuclides in high-level nuclear waste: Overview and requirements

    This paper, and this topical session on Nuclear Waste Minimization, Management and Remediation, focuses on two nuclear systems, and their associated technologies, that have the potential to address concerns surrounding long-lived radionuclides in high-level waste. Both systems offer technology applicable to HLW from present light-water reactors (LWR). Additionally these systems represent advanced nuclear power concepts that have important features associated with integrated management of wastes, long-term fuel supplies, and enhanced safety. The first system is the Integral Fast Reactor (IFR) concept. This system incorporates a metal-fueled fast reactor coupled with chemical separations based on pyroprocessing to produce power while simultaneously burning long-lived actinide waste. IFR applications include burning of actinides from current LWR spent fuel and energy production in a breeder environment. The second concept, Accelerator Transmutation of Waste (ATW), is based upon an accelerator-induced intense source of thermal neutrons and is aimed at destruction of long-lived actinides and fission products. This concept can be applied to long-lived radionuclides in spent fuel HLW as well as a future fission power source built around use of natural thorium or uranium as fuels coupled with concurrent waste destruction

    Pyrochemical processing, or {open_quotes}pyroprocessing,{close_quotes} of spent fuel offers a number of unique advantages, particularly in comparison with coventional aqueous solvent extraction techniques. Pyroprocessing, in its present version, has been under development for nearly ten years. Emphasis has been placed on the development of a simple, efficient process that features compact, inexpensive process equipment. Particular attention has been paid to the minimization of waste volumes and to the development of a process that is both economic and environmentally sound as well as proliferation-resistant.

    1993-01-01

    During the past few years, Argonne National Laboratory has been developing the integral fast reactor (IFR), an advanced liquid-metal reactor concept. In the IFR, the inherent properties of liquid-metal cooling are combined with a new metallic fuel and a radically different refining process to allow breakthroughs in passive safety, fuel cycle economics, and waste management. A key feature of the IFR concept is its unique pyroprocessing. Pyroprocessing has the potential to radically improve long-term waste management strategies by exploiting the following attributes: 1. Minor actinides accompany plutonium product stream; therefore, actinide recycling occurs naturally. Actinides, the primary source of long-term radiological toxicity, are removed from the waste stream and returned to the reactor for in situ burning, generating useful energy. 2. High-level waste volume from pyroprocessing call be reduced substantially as compared with direct disposal of spent fuel. 3. Decay heat loading in the repository can be reduced by a large factor, especially for the long-term burden. 4. Low-level waste generation is minimal. 5. Troublesome fission products, such as 99 Tc, 129 I, and 14 C, are contained and immobilized. Singly or in combination, the foregoing attributes provide important improvements in long-term waste management in terms of the ease in meeting technical performance requirements (perhaps even the feasibility of demonstrating that technical performance requirements can be met) and perhaps also in ultimate public acceptance. Actinide recycling, if successfully developed, could well help the current repository program by providing an opportunity to enhance capacity utilization and by deferring the need for future repositories. It also represents a viable technical backup option in the event unforeseen difficulties arise in the repository licensing process

  2. Investigations for the Recycle of Pyroprocessed Uranium

    Given the renewed interest in uranium from the pyroprocessing of used nuclear fuel in a molten salt system, the two biggest hurdles for marketing the uranium are radiation levels and transuranic content. A radiation level as low as possible is desired so that handling operations can be performed directly with the uranium. The transuranic content of the uranium will affect the subsequent waste streams generated and, thus also should be minimized. Although the pyroprocessing technology was originally developed without regard to radiation and transuranic levels, adaptations to the process have been considered. Process conditions have been varied during the distillation and casting cycles of the process with increasing temperature showing the largest effect on the reduction of radiation levels. Transuranic levels can be reduced significantly by incorporating a pre-step in the salt distillation operation to remove a majority of the salt prior to distillation.

    A major element of the shutdown of the US liquid metal reactor development program is managing the sodium-bonded spent metallic fuel from the Experimental Breeder Reactor-II to meet US environmental laws. Argonne National Laboratory has refurbished and equipped an existing hot cell facility for treating the spent fuel by a high-temperature electrochemical process commonly called pyroprocessing. Four products will be produced for storage and disposal. Two high-level waste forms will be produced and qualified for disposal of the fission and activation products. Uranium and transuranium alloys will be produced for storage pending a decision by the US Department of Energy on the fate of its plutonium and enriched uranium. Together these activities will demonstrate a unique electrochemical treatment technology for spent nuclear fuel. This technology potentially has significant economic and technical advantages over either conventional reprocessing or direct disposal as a high-level waste option

    The integral fast reactor (IFR) is an advanced liquid-metal-cooled reactor (ALMR) concept being developed at Argonne National Laboratory. The IFR program is specifically responsible for the irradiation performance, advanced core design, safety analysis, and development of the fuel cycle for the US Department of Energy's ALMR program. The basic elements of the IFR concept are (a) metallic fuel, (b) liquid-sodium cooling, (c) modular, pool-type reactor configuration, (d) an integral fuel cycle based upon pyrometallurgical processing. The most significant safety aspects of the IFR program result from its unique fuel design, a ternary alloy of uranium, plutonium, and zirconium. This fuel is based on experience gained through > 25 yr operation of the Experimental Breeder Reactor II (EBR-II) with a uranium alloy metallic fuel. The ultimate criteria for fuel pin design is the overall integrity at the target burnup. The probability of core meltdown is remote; however, a theoretical possibility of core meltdown remains. The next major step in the IFR development program will be a full-scale pyroprocessing demonstration to be carried out in conjunction with EBR-II. The IFR fuel cycle closure based on pyroprocessing will also have a dramatic impact on waste management options and on actinide recycling

    Highlights: ► The conceptual design of a pyroprocess demonstration facility was performed. ► The design requirements for the pyroprocess hot cell and equipment were determined. ► The maintenance concept for the pyroprocess hot cell was presented. -- Abstract: The development of an effective management technology of spent fuel is important to enhance environmental friendliness, cost viability and proliferation resistance. In Korea, pyroprocess technology has been considered as a fuel cycle option to solve the spent fuel accumulation problems. PRIDE (PyRoprocess Integrated inactive DEmonstration facility) has been developed from 2007 to 2012 in Korea as a cold test facility to support integrated pyroprocessing and an equipment demonstration, which is essential to verify the pyroprocess technology. As the next stage of PRIDE, the design requirements of an engineering-scale demonstration facility are being developed, and the preliminary conceptual design of the facility is being performed for the future. In this paper, the main design requirements for the engineering-scale pyroprocess demonstration facility were studied in the throughput of 10tHM a year. For the preliminary conceptual design of the facility, the design basis of the pyroprocess hot cell was suggested, and the main equipment, main process area, operation area, maintenance area, and so on were arranged in consideration of the effective operation of the hot cells. Also, the argon system was designed to provide and maintain a proper inert environment for the pyroprocess. The preliminary conceptual design data will be used to review the validity of the engineering-scale pyroprocess demonstration facility that enhances both safety and nonproliferation

    Full Text Available Pyroprocessing technology has been regarded as a promising solution for recycling spent fuel in nuclear power plants. The Korea Atomic Energy Research Institute has been studying the current status of equipment and facilities for pyroprocessing and found that existing facilities are manually operated; therefore, their applications have been limited to laboratory scale because of low productivity and safety concerns. To extend the pyroprocessing technology to a commercial scale, the facility, including all the processing equipment and the material-handling devices, should be enhanced in view of automation. In an automated pyroprocessing facility, a supervised control system is needed to handle and manage material flow and associated operations. This article provides a preliminary design of the supervising system for pyroprocessing. In particular, a manufacturing execution system intended for an automated pyroprocessing facility, named Pyroprocessing Execution System, is proposed, by which the overall production process is automated via systematic collaboration with a planning system and a control system. Moreover, a simulation-based prototype system is presented to illustrate the operability of the proposed Pyroprocessing Execution System, and a simulation study to demonstrate the interoperability of the material-handling equipment with processing equipment is also provided.

    2013-09-01

    The development of a radioactive waste disposal system is indispensable in maintaining the sustainability of nuclear energy. The Korea Atomic Energy Research Institute (KAERI) has studied the direct geological disposal of spent nuclear fuel since 1997. KAERI has also focused on the development of processes suitable for reducing the volume of spent nuclear fuel and the recycling of valuable fissile material. One of the most promising technologies investigated by KAERI is the pyro-processing of spent nuclear fuel followed by the geological disposal of the generated high level waste (HLW). Since 2007, KAERI has been running a research programme focusing on the recycling of spent nuclear fuel, as well as studies aimed at the development of a relevant geological disposal system able to accept the resulting HLW. The core aims of the KAERI study were to characterize the geological media, design a repository system and assess the overall safety of the disposal system. The development of pyro-processing technology is ongoing and has not yet been demonstrated at the commercial level. Thus, the government of the Republic of Korea requested an assessment of the technical feasibility of this technology. The assessment also included the appraisal of a disposal solution for waste generated by pyro-processing. With regard to the latter, KAERI requested that the IAEA review the status of the disposal project within the Waste Management Assessment and Technical Review Programme (WATRP). Peer reviews are increasingly being acknowledged as an important element in building broader stakeholder confidence in the safety and viability of related facilities. This report presents the consensus view of the international group of experts convened by the IAEA to perform the review

    Argonne National Laboratory's (ANL'S) effort to pursue the exploitation of liquid metal cooled reactor (LMR) characteristics has given rise to the Integral Fast Reactor (IFR) concept, and has produced substantial technical advancement in concept implementation which includes demonstration of high burnup capability of metallic fuel, demonstration of injection casting fabrication, integral demonstration of passive safety response, and technical feasibility of pyroprocessing. The first half decade of the 90's will host demonstration of the IFR closed fuel cycle technology at the prototype scale. The EBR-II reactor will be fueled with ternary alloy fuel in HT-9 cladding and ducts, and pyroprocessing and injection casting refabrication of EBR-II fuel will be conducted using near-commercial sized equipment at the Fuel cycle Facility (FCF) which is co-located adjacent to EBR-II. Demonstration will start in 1992. The demonstration of passive safety response achievable with the IFR design concept, (already done in EBR-II in 1986) will be repeated in the mid 90's using the IFR prototype recycle fuel from the FCF. The demonstration of scrubbing of the reprocessing fission product waste stream, with recycle of the transuranics to the reactor for consumption, will also occur in the mid 90's. 30 refs

    A major issue surrounding current nuclear power generation is the management and disposal of long-lived, high-level waste (HLW). The planned and scientifically acceptable destination for this waste is in deep underground, geologically stable, repositories. However, public concerns surrounding such disposal of long-lived nuclear wastes and other issues such as proliferation and safety negatively affect the potential role that nuclear power can play in meeting current and future national energy needs. This paper and this topical session on nuclear waste minimization, management, and remediation focus on two nuclear systems and their associated technologies that have the potential to address concerns surrounding long-lived radionuclides in HLW. Both systems offer technology applicable to HLW from current light water reactors (LWRs). In addition, these systems represent advanced nuclear power concepts that have important features associated with integrated management of wastes long-term fuel supplies, and enhanced safety. The first system is the integral fast reactor (IFR) concept. This system incorporates a metal-fueled fast reactor coupled with chemical separations based on pyroprocessing to produce power while burning long-lived actinide waste. The IFR applications include the burning of actinides from current LWR spent fuel and energy production in a breeder environment.

This concept can be applied to long-lived radionuclides in spent-fuel HLW as well as a future fission power source built around use of natural thorium or uranium as fuels coupled with concurrent waste destruction

    Glass-ceramics containing calcium neodymium(cerium) oxide silicate [Ca{sub 2}Nd{sub 8-x}Ce{sub x}(SiO{sub 4}){sub 6}O{sub 2}] crystals were fabricated for the immobilization of radioactive wastes that contain large portions of rare-earth ions. Controlled crystallization of alkali borosilicate glasses by heating at T ≥ 750 °C for 3 h formed hexagonal Ca–silicate crystals. Maximum lanthanide oxide waste loading was >26.8 wt.%. Ce and Nd ions were highly partitioned inside Ca–silicate crystals compared to the glass matrix; the rare-earth wastes are efficiently immobilized inside the crystalline phases. The concentrations of Ce and Nd ions released in a material characterization center-type 1 test were below the detection limit (0.1 ppb) of inductively coupled plasma mass spectroscopy. Normalized release values performed by a product consistency test were 2.64·10{sup −6} g m{sup −2} for Ce ion and 2.19·10{sup −6} g m{sup −2} for Nd ion. Results suggest that glass-ceramics containing calcium neodymium(cerium) silicate crystals are good candidate wasteforms for immobilization of lanthanide wastes generated by pyro-processing. - Highlights: • Glass-ceramic wasteforms containing Ca{sub 2}Nd{sub 8-x}Ce{sub x}(SiO{sub 4}){sub 6}O{sub 2} crystals were synthesized to immobilize lanthanide wastes. • Maximum lanthanide oxide waste loading was >26.8 wt.%. • Ce and Nd ions were highly partitioned inside Ca–Nd–silicate crystals compared to glass matrix. • Amounts of Ce and Nd ions released in the material characterization center-type 1 were below the detection limit (0.1 ppb). • Normalized release values performed by a PCT were 2.64• 10{sup −6} g m{sup −2} for Ce ions and 2.19• 10{sup −6} g m{sup −2} for Nd ions.

    The Integral Fast Reactor (IFR) concept has been under development at Argonne National Laboratory since 1984. A key feature of the IFR concept is the metallic fuel. Metallic fuel was the original choice in early liquid metal reactor development. Solid technical accomplishments have been accumulating year after year in all aspects of the IFR development program. But as we make technical progress, the ultimate potential offered by the IFR concept as a next generation advanced reactor becomes clearer and clearer. The IFR concept can meet all three fundamental requirements needed in a next generation reactor. This document discusses these requirements: breeding, safety, and waste management. 5 refs., 4 figs

    Finally, Integral Fast Reactor (IFR) pyroprocessing has been developed only in recent years and it appears to have potential as a relatively uncomplicated, effective actinide recovery process. In fact, actinide recycling occurs naturally in the IFR fuel cycle. Although still very much developmental, the entire IFR fuel cycle will be demonstrated on prototype-scale in conjunction with the EBR-II and its refurbished Fuel Cycle Facility starting in late 1991. A logical extension to this work, therefore, is to establish whether this IFR pyrochemical processing can be applied to extracting actinides from LWR spent fuel. This paper summarizes current thinking on the rationale for actinide recycle, its ramifications on the geologic repository and the current high-level waste management plans, and the necessary development programs. 4 figs., 4 tabs

    1992-01-01

    A significant attribute of the Integral Fast Reactor (IFR) concept is the transmutation of long-lived minor actinide fission products. These isotopes require isolation for thousands of years, and if they could be removed from the waste, disposal problems would be reduced. The IFR utilizes pyroprocessing of metallic fuel to separate auranium, plutonium, and the minor actinides from nonfissionable constituents. These materials are reintroduced into the fuel and reirradiated. Spent IFR fuel is expected to contain low levels of americium, neptunium, and curium because the hard neutron spectrum should transmute these isotopes as they are produced. This opens the possibility of using an IFR to trnasmute minor actinide waste from conventional light water reactors (LWRs). A standard IFR fuel is based on the alloy U-20% Pu-10% Zr (in weight percent). A metallic fuel system eases the requirements for reprocessing methods and enables the minor actinide metals to be incorporated into the fuel with simple modifications to the basic fuel casting process. In this paper, the authors report the initial casting experience with minor actinide element addition to an IFR U-Pu-Zr metallic fuel

    The pyroprocess produces U/TRU metal ingots using four important processes, pretreatment, electrochemical reduction, electrorefining and electrowinning, in order to recycle spent fuel. KAPF+'s capacity is shown the cost that is injected into the KAPF+. The pyroprocess unit cost is data that are essential for inputting to calculate the pyroprocess-Sodiumcooled Fast Reactor (SFR) nuclear fuel cycle cost. Moreover, since the pyroprocess facility's depreciation cost is included in the manufacturing indirect cost of the pyroprocess cost, it can become an important element for judging the pyroprocess' economic viability. Since the pyroprocess unit cost calculates the sum of the costs that are incurred each year by dividing with the total amount of U/TRU ingot produced, the pyroprocess unit cost uncertainty increases as well when the uncertainty of the costs incurred by each year increases. KAPF+, which is a commercialization facility, was set as the cost object, and the existing methods (straightline method and fixed percentage of declining-balance method) used today and the depreciation cost of the ADDM were subjected to a comparative analysis. The results are as follows. First, in case of the straight-line method that calculated the durable period as 40 years, and in case of ADDM that factored in a 5% deceleration rate, the difference in the depreciation costs of $65.26/kgHM and $119.05/kgHM resulted during the first and last years, respectively. Accordingly, it was analyzed that there is a significant difference in terms of the cost of the capital investment every year depending on the depreciation method. Secondly, since the depreciation cost is a component of the manufacturing indirect cost, it is necessary to maintain a trend that is similar to that of the direct labor cost in addition to the direct material cost.

Since the pyroprocess unit cost calculates the sum of the costs that are incurred each year by dividing with the total amount of U/TRU ingot produced, the pyroprocess unit cost uncertainty increases as well when the uncertainty of the costs incurred by each year increases. KAPF+, which is a commercialization facility, was set as the cost object, and the existing methods (straightline method and fixed percentage of declining-balance method) used today and the depreciation cost of the ADDM were subjected to a comparative analysis. The results are as follows. First, in case of the straight-line method that calculated the durable period as 40 years, and in case of ADDM that factored in a 5% deceleration rate, the difference in the depreciation costs of $65.26/kgHM and $119.05/kgHM resulted during the first and last years, respectively. Accordingly, it was analyzed that there is a significant difference in terms of the cost of the capital investment every year depending on the depreciation method. Secondly, since the depreciation cost is a component of the manufacturing indirect cost, it is necessary to maintain a trend that is similar to that of the direct labor cost in addition to the direct material cost

    KAERI has developed the KIEP-21 (Korean, Innovative, Environmentally Friendly, and Proliferation Resistant System for the 21st Century). It is an advanced nuclear fuel cycle option with a pyro-process and a GEN-IV SFR. A pyro-process consists of two distinctive processes, an electrolytic reduction process and an electro-refining and winning process. When the pyro-process is applied, it generates five streams of wastes. To compare pyro-process advantage over the direct disposal of Spent Nuclear Fuel (SNF), the PWR SNF of the 45,000 MWD burn-up has been assumed. A safety assessment model for pyro-process wastes and representative results are presented in this report

    In the Integral Fast Reactor (IFR) development program, the entire reactor system -- reactor, fuel cycle, and waste process is being developed and optimized at the same time as a single integral entity. The use of metallic fuel in the IFR allows a radically improved fuel cycle technology. Based on the recent IFR process development, a preliminary assessment has been made to investigate the feasibility of further adapting pyrochemical processes to directly extract actinides from LWR spent fuel. The results of this assessment indicate very promising potential and two most promising flowsheet options have been identified for further research and development. This paper also summarizes current thinking on the rationale for actinide recycle, its ramifications on the geologic repository and the current high-level waste management plans, and the necessary development programs

    Dynamic changes according to the batch operation cannot be predicted in an equilibrium material flow. This study began to build a dynamic material balance model based on the previously developed pyroprocessing flowsheet. As a mid- and long-term research, an integrated pyroprocessing simulator is being developed at the Korea Atomic Energy Research Institute (KAERI) to cope with a review on the technical feasibility, safeguards assessment, conceptual design of facility, and economic feasibility evaluation. The most fundamental thing in such a simulator development is to establish the dynamic material flow framework. This study focused on the operation modeling of pyroprocessing to implement a dynamic material flow. As a case study, oxide reduction was investigated in terms of a dynamic material flow. DES based modeling was applied to build a pyroprocessing operation model. A dynamic material flow as the basic framework for an integrated pyroprocessing was successfully implemented through ExtendSim's internal database and item blocks. Complex operation logic behavior was verified, for example, an oxide reduction process in terms of dynamic material flow. Compared to the equilibrium material flow, a model-based dynamic material flow provides such detailed information that a careful analysis of every batch is necessary to confirm the dynamic material balance results. With the default scenario of oxide reduction, the batch mass balance was verified in comparison with a one-year equilibrium mass balance. This study is still under progress with a mid-and long-term goal, the development of a multi-purpose pyroprocessing simulator that is able to cope with safeguards assessment, economic feasibility, technical evaluation, conceptual design, and support of licensing for a future pyroprocessing facility

    Analysis of foreign and domestic patents for pyroprocessing technology of spent nuclear fuels was carried out in this study. The current status of pyroprocessing technology development in such countries as Korea, USA, Japan and EU was analyzed by classifying the patents for 1975 through 2009 according to registration country, assignee, calendar year and technology area. The major assignees' activity indices were compared in order to find out whether there is any concentrated area of technical details. Technology competitiveness of the countries was also investigated from the information of patent citation number and family size. Furthermore, some essential unit technologies required for the commercialization of pyroprocessing were derived and examined in the aspect of the state of art as well as the trend of technology development.

    The objective of this project is to analyze the safeguard ability of pyroprocess facility and to establish the safeguards system for pyroprocess by developing the technology of nuclear material accounting for unit process, surveillance technology and nuclear characteristic analysis technology which are needed to demonstrate the safeguards technology of pyroprocess. Therefore, the development of a safeguards approach for pyroprocessing facilities is required as the interest of pyroprocessing increases. Regarding this issue, the IAEA made a contract the 3-years long Member State Support Program (MSSP) for the 'Support for Development of a Safeguards Approach for a Pyroprocessing Plant' with the Republic of Korea (ROK) in July 2008. Even though the pyroprocess technology is currently being developed all over the world, its safeguards approach has not been established yet, and especially, nuclear material accountancy technology which is the core of safeguards has not been established as well. Therefore, the development of new accountancy technology which is appropriate for the construction of pyroprocess facility is needed. Due to the nature of the process, pyroprocess has various kinds of process material form, and the composition of Pu and U isotopes included in process material is not homogeneous. Also, the existing nuclear material accountancy technology for a wet reprocessing facility is hard to apply because of a large quantity of gamma-ray radiation which is emitted from the fissile products in process material. In this report, the study for the development of a safeguards approach for a pyroprocessing plant pyroprocessing has been described. As the previous results six pyroprocessing facility concepts suggested by US, Japan, and Republic of Korea had been summarized and analyzed, and the determination principles were established to determine a reference pyroprocessing facility concept. The reference pyroprocessing facility was determined to be the ESPF of KAERI

    The objective of this study is to evaluate prospects for a practical use of pyroprocess through analysis of current issues and status of pyroprocess technology development being performed at domestic and abroad. Following Fukushima accident, awareness about nuclear safety is further increasing and problems on safe management of used nuclear fuel has emerged as well. So, nuclear industrialized countries are developing recycling technology of used nuclear fuel, significantly reducing used fuel inventory that have cumulated. In this respects, there is a need to comprehensively summarize the technology developed at KAERI until now. In addition to, the current issues of pyroprocess for future R and D are suggested

  11. The design rationale of the Integral Fast Reactor (IFR)

    The Integral Fast Reactor (IFR) concept has been developed over the last ten years to provide technical solutions to perceptual concerns associated with nuclear power. Beyond the traditional advanced reactor objectives of increased safety, improved economy and more efficient fuel utilization, the IFR is designed to simplify waste disposal and increase resistance to proliferation. Only a fast reactor with an efficient recycle technology can provide for total consumption of actinides. The basic physics governing reactor design dictates that, for efficient recycle, the fuel form should be limited in burnup only by radiation damage to fuel cladding. The recycle technology must recover essentially all actinides. In a fast reactor, not all fission products need to be removed from the recycled fuel, and there is no need to produce pure plutonium. Recovery, recycle, and ultimate consumption of all actinides resolves several waste-disposal concerns. The IFR can be configured to achieve safe passive response to any of the traditional postulated reactor accident initiators, and can be configured for a variety of power output levels. Passive heat removal is achieved by use of a large inventory sodium coolant and a physical configuration that emphasizes natural circulation. An IFR can be designed to consume excess fissile material, to produce a surplus, or to maintain inventory. It appears that commercial designs should be economically competitive with other available alternatives. (author)

    Highlights: • Conceptual design is created for a pilot pyroprocessing plant treating PWR spent fuel. • Pilot-scale design is based on a capacity of 400 tHM/yr with 60 years lifetime. • All individual processes are integrated into a single system from feed to products. • Overall facility design is developed for a pilot pyroprocessing plant. • Unit process cost is estimated for pyroprocessing with uncertainties. - Abstract: Korea has developed pyroprocessing technology as a potential option for recycling spent fuels (SFs) from pressurized water reactors (PWRs). The pyroprocessing consists of various key unit processes and a number of research activities have been focused on each process. However, to realize the whole pyroprocessing concept, there is a critical need for integrating the individual developments and addressing a material flow from feed to final products. In addition, the advancement on overall facility design is an indispensable aspect for demonstration and commercialization of the pyroprocessing. In this study, a facility named as Korea Advanced Pyroprocess Facility Plus (KAPF+) is conceptualized with a capacity of 400 tHM/yr. The process steps are categorized based on their own characteristics while the capacities of process equipment are determined based on the current technical levels. The facility concept with a site layout of 104,000 m{sup 2} is developed by analyzing the operation conditions and materials treated in each process. As an economic approach to the proposed facility, the unit cost (781 $/kgHM denominated in 2009 USD) for KAPF+ is also analyzed with the conceptual design with preliminary sensitivity assessments including decontamination and decommissioning costs, a discount rate, staffing costs, and plant lifetime. While classifying and describing cost details of KAPF+, this study compares the unit cost of KAPF+ treating PWR SF to that of the pyroprocessing facility treating sodium-cooled fast reactor (SFR) SF.

    The concept of Safeguards-By-Design (SBD), which is proposed and developed by the United States and the IAEA, is now widely acknowledged as a fundamental consideration for the effective and efficient implementation of safeguards. The application of a SBD concept is of importance especially for developmental nuclear facilities which have new technological features and relevant challenges to their safeguards approach. At this point of time, the examination of the applicability of SBD on a pyroprocessing facility, which has been being developed in the Republic of Korea (ROK), would be meaningful. The ROK developed a safeguards system with the concept of SBD for Advanced spent fuel Conditioning Process Facility (ACPF) and DUPIC Fuel Development Facility (DFDF) before the SBD concept was formally suggested. Currently. The PRIDE (PyRoprocess Integrated Inactive Demonstration) facility for the demonstration of pyroprocess using 10 ton of non-radioactive nuclear materials per year is being constructed in the ROK. The safeguards system for the facility has been designed in cooperation with a facility designer from the design phase, and the safeguards system would be established according to the future construction schedule. In preparing the design of Engineering Scale Pyroprocess Facility (ESPF), which will use spent fuels in an engineering scale and be constructed in 2016, a research on the safeguards system for this facility is also being conducted. In this connection, a project to support for development of safeguards approach for a reference pyroprocessing facility has been carried out by KAERI in cooperation with KINAC and the IAEA through an IAEA Member State Support Program (MSSP). When this MSSP project is finished in August, 2011, a safeguards system model and safeguards approach for a reference pyroprocessing facility would be established. Maximizing these early experiences and results, a safeguards system of ESPF based on the concept of SBD would be designed and

    Pyroprocessing is an electrochemical method based on the molten salt electrolyte, mainly the LiCl-KCl eutectic molten salt, to recycle the used nuclear fuel. For a conceptual design of commercial pyroprocessing facility, tons of special nuclear materials, namely U and Pu, may be involved, which could be used for non-peaceful purposes if they are diverted. Effective safeguards approaches have to be developed prior to the development and construction of a pyroprocessing facility. Present research focused on two main objectives, namely calculating the properties of nuclear species in LiCl-KCl molten salt and developing integrated model to safeguard a pyroprocessing facility. Understanding the characteristics of special nuclear materials in LiCl-KCl eutectic salt is extremely important to understand their behaviors in an electrorefiner. The model development for the separation processes in the pyroprocessing, including electrorefining, actinide drawdown, and rare earth drawdown benefits the understanding of material transport and separation performance of these processes under various conditions. The output signals, such as potential, current, and species concentration contribute to the material balance closure and provide safeguards signatures to detect the scenarios of diversion. U and Pu are the two main elements concerned in this study due to our interest in safeguards.

    Nuclear energy is expected to meet the growing energy demand while avoiding CO{sub 2} emission. However, the problem of accumulating spent fuel from current nuclear power plants which is mainly composed of uranium oxides should be addressed. One of the most practical solutions is to reduce the spent oxide fuel and recycle it. Next-generation fuel cycles demand innovative features such as a reduction of the environmental load, improved safety, efficient recycling of resources, and feasible economics. Pyroprocessing based on molten salt electrolysis is one of the key technologies for reducing the amount of spent nuclear fuel and destroying toxic waste products, such as the long-life fission products. The oxide reduction process based on the electrochemical reduction in a LiCl-Li{sub 2}O electrolyte has been developed for the volume reduction of PWR (Pressurized Water Reactor) spent fuels and for providing metal feeds for the electrorefining process. To speed up the electrochemical reduction process, the influences of the feed form for the cathode and the type of anode shroud on the reduction rate were investigated.

    This study set the pyroprocess facility at an engineering scale as a cost object, and presented the cost consumed during the unit processes of the pyroprocess. For the cost calculation, the activity based costing (ABC) method was used instead of the engineering cost estimation method, which calculates the cost based on the conceptual design of the pyroprocess facility. The calculation results demonstrate that the pyroprocess facility's unit process cost is $194/kgHM for pretreatment, $298/kgHM for electrochemical reduction, $226/kgHM for electrorefining, and $299/kgHM for electrowinning. An analysis demonstrated that the share of each unit process cost among the total pyroprocess cost is as follows: 19% for pretreatment, 29% for electrochemical reduction, 22% for electrorefining, and 30% for electrowinning. The total unit cost of the pyroprocess was calculated at $1,017/kgHM. In the end, electrochemical reduction and the electrowinning process took up most of the cost, and the individual costs for these two processes was found to be similar. This is because significant raw material cost is required for the electrochemical reduction process, which uses platinum as an anode electrode. In addition, significant raw material costs are required, such as for Li3PO4, which is used a lot during the salt purification process.

    Large quantities of actinide elements are present in irradiated light water reactor fuel that is stored throughout the world. Because of the high fission to capture ratio for the transuranium (TRU) elements with the high energy neutrons in metal-fueled integral fast reactors (IFR), that reactor can consume these elements effectively. The stored fuel may represent valuable resource for the expanding application of fast power reactors. In addition, the removal of TRU elements from spent LWR fuel has the potential for increasing the capacity of high level waste facilities by reducing the heat load and may increase the margin of safety in meeting licensing requirement. Argonne National Laboratory is developing a pyrochemical process, which is compatible with the IFR fuel cycle for the recovery of TRU elements from LWR fuel. The proposed product is a metallic actinide ingot, which can be introduced into the electrorefining step of the IFR process. Two pyrochemical processes, that is, salt transport process and blanket processing study, are discussed in this paper. Also the experimental studies are reported. (K.I.)

    Reprocessing using pyrometallurgical processes is generally considered to have economical benefits comparing with conventional aqueous processes because of the combination of simpler process and equipments, less criticality, and more compact facilities. On the other hand, the pyrometallurgical processes must generate peculiar wastes and R and D on those wastes is slightly inferior, as compared with the main processes. In this paper, process flows of major pyrometallurgical processes are firstly summarized and, then, the present R and D condition on the wastes are shown. (author)

    Nuclear fuel cycle facility that treats with spent fuel must be designed and manufactured a Pyroprcess facility and process with considering a speciality as every process have to be processed remotely. To prevent an unexpected accident under a circumstance that must operate with a remote manipulator after done the Pyroprocess facility, an procedure related Pyroprocess operation and maintenance need to establish it in the early design stage. To develop the simulator that is mixed by 3D modelling and simulation, a system architecture was designed. A full-scale digital mockup with a real pyroprocess facility was designed and manufactured. An inverse kinematics algorithm of remote manipulator was created in order to simulate an accident and repair that could happen in pyroprocess operation and maintenance under a virtual digital mockup environment. Deployment analysis of process devices through a workspace analysis was carried out and Accessibility analysis by using haptic device was examined

    The purpose of this study is to present a rational depreciation method for a pyroprocess cost calculation. Toward this end, the so-called advanced decelerated depreciation method (ADDM) was developed that complements the limitations of the existing depreciation methods such as the straight-line method and fixed percentage of declining-balance method. ADDM was used to show the trend of the direct material cost and direct labor cost compared to the straight-line or fixed percentage of the declining-balance methods that are often used today. As a result, it was demonstrated that the depreciation cost of the ADDM, which assumed a pyroprocess facility's life period to be 40 years with a deceleration rate of 5%, takes up 4.14% and 27.74% of the pyroprocess unit cost ($781/kg heavy metal) in the 1st and final years, respectively. In other words, it was found that the ADDM can cost the pyroprocess facility's capital investment rationally every year. Finally, ADDM's validity was verified by confirming that the sum of the depreciation cost by year, and the sum of the purchasing cost of the building and equipment, are the same.

    A metallic fuel alloy, nominally U-20-Pu-lOZr, is the key element of the Integral Fast Reactor (IFR) fuel cycle. Metallic fuel permits the use of an innovative, simple pyrometallurgical process, known as pyroprocessing, (the subject of this report), which features fused salt electrorefining of the spent fuel. Electrorefining separates the actinide elements from fission products, without producing a separate stream of plutonium. The plutonium-bearing product is contaminated with higher actinides and with a minor amount of rare earth fission products, making it diversion resistant while still suitable as a fuel material in the fast spectrum of the IFR core. The engineering-scale demonstration of this process will be conducted in the refurbished EBR-II Fuel Cycle Facility, which has entered the start-up phase. An additional pyrometallurgical process is under development for extracting transuranic (TRU) elements from Light Water Reactor (LWR) spent fuel in a form suitable for use as a feed to the IFR fuel cycle. Four candidate extraction processes have been investigated and shown to be chemically feasible. The main steps in each process are oxide reduction with calcium or lithium, regeneration of the reductant and recycle of the salt, and separation of the TRU product from the bulk uranium. Two processes, referred to as the lithium and salt transport (calcium reductant) processes, have been selected for engineering-scale demonstration, which is expected to start in late 1993. An integral part of pyroprocessing development is the treatment and packaging of high-level waste materials arising from the operations, along with the qualification of these waste forms for disposal in a geologic repository

    Highlights: • Pyroprocess facility’s direct cost was calculated based on the conceptual design. • The unit cost of pyroprocess was calculated as $781/kgHM. • The unit cost was increased by 3%, considering labor allocation standards. • The operating and maintenance cost was identified as a main cost driver. - Abstract: This study postulated a commercial pyroprocess facility (KAPF+: Korea Advanced Pyroprocess Facility Plus) with a processing capacity of 400 tons/year as a cost object, and utilized an engineering cost estimation method based on a conceptual design to present the results of the total cost and unit cost estimation. According to the calculation results, the total cost and unit cost were calculated with k$779,386 and $781/kgHM, respectively. Moreover, the key cost driver was manifested as the operating and maintenance costs. In particular, equipment replacement cost was identified as an important cost driver. In addition, for an increasingly accurate cost estimation, the calculation results and allocation method of the indirect cost were reanalyzed. Finally the pyroprocess unit cost increased $5 when calculated the indirect cost using the labor time as the allocation standard. Meanwhile, the pyroprocess unit cost increased $22 as a result of allocating the indirect cost using the uniform labor cost as the cost allocation standard. Accordingly, an indirect cost allocation standard was manifested as the factor that exerts a significant effect on the pyroprocess unit cost

    The processing of Integral Fast Reactor (IFR) metal fuel utilizes pyrochemical fuel reprocessing steps. These steps include separation of the fission products from uranium and plutonium by electrorefining in a fused salt, subsequent concentration of uranium and plutonium for reuse, removal, concentration, and packaging of the waste material. Approximately two years ago a facility became operational at Argonne National Laboratory-Illinois to establish the chemical feasibility of proposed reprocessing and consolidation processes. Sensitivity of the pyroprocessing melts to air oxidation necessitated operation in atmosphere-controlled enclosures. The Integral Fast Reactor Fuels Reprocessing Laboratory is described

    1986-01-01

    The Integral Fast Reactor (IFR) is a concept for a self-contained facility in which several sodium-cooled fast reactors of moderate size are located at the same site along with complete fuel-recycle and waste-treatment facilities. After the initial core loading with enriched uranium or plutonium, only natural or depleted uranium is shipped to the plant, and only wastes in final disposal forms are shipped out. The reactors have driver and blanket fuels of uranium-plutonium-zirconium alloys in stainless steel cladding. The use of metal alloy fuels is central to the IFR concept, contributing to the inherent safety of the reactor, the ease of reprocessing, and the relatively low capital and operating costs. Discharged fuels are recovered in a pyrochemical process that consists of two basic steps: an electrolytic process to separate fission products from actinides, and halide slagging to separate plutonium from uranium

    This report summarizes treatment and waste form options being evaluated for waste streams resulting from the electrochemical/pyrometallurgical (pyro ) processing of used oxide nuclear fuel. The technologies that are described are South Korean (Republic of Korea – ROK) and United States of America (US) ‘centric’ in the approach to treating pyroprocessing wastes and are based on the decade long collaborations between US and ROK researchers. Some of the general and advanced technologies described in this report will be demonstrated during the Integrated Recycle Test (IRT) to be conducted as a part of the Joint Fuel Cycle Study (JFCS) collaboration between US Department of Energy (DOE) and ROK national laboratories. The JFCS means to specifically address and evaluated the technological, economic, and safe guard issues associated with the treatment of used nuclear fuel by pyroprocessing. The IRT will involve the processing of commercial, used oxide fuel to recover uranium and transuranics. The recovered transuranics will then be fabricated into metallic fuel and irradiated to transmutate, or burn the transuranic elements to shorter lived radionuclides. In addition, the various process streams will be evaluated and tested for fission product removal, electrolytic salt recycle, minimization of actinide loss to waste streams and waste form fabrication and characterization. This report specifically addresses the production and testing of those waste forms to demonstrate their compatibility with treatment options and suitability for disposal.

    1992-01-01

    The pyrometallurgical processing of spent fuel from the Integral Fast Reactor (IFR) results in a waste of LiCl-KCl-NaCl salt containing approximately 10 wt% fission products, primarily CsCl and SrCl 2 . For disposal, this waste must be immobilized in a form that it is leach resistant. A salt-occluded zeolite has been identified as a potential waste form for the salt. Its leach resistance properties were investigated using powdered samples. The results were that strontium was not released and cesium had a low release, 0.056 g/m 2 for the 56 day leach test. The initial release (within 7 days) of alkali metal cations was rapid and subsequent releases were much smaller. The releases of aluminum and silicon were 0.036 and 0.028 g/m 2 , respectively, and were constant. Neither alkali metal cation hydrolysis nor exchange between cations in the leachate and those in the zeolite was significant. Only sodium release followed t 0.5 kinetics. Selected dissolution of the occluded salt was the primary release process. These results confirm that salt-occluded zeolite has promise as the waste form for IFR pyroprocess salt

    The liquid-metal reactor (LMR) has the potential to extend the uranium resource by a factor of 50 to 100 over current commercial light water reactors (LWRs). In the integral fast reactor (IFR) development program, the entire reactor system - reactor, fuel cycle, and waste process - is being developed and optimized at the same time as a single integral entity. A key feature of the IFR concept is the metallic fuel. The lead irradiation tests on the new U-Pu-Zr metallic fuel in the Experimental Breeder Reactor II have surpassed 185000 MWd/t burnup, and its high burnup capability has now been fully demonstrated. The metallic fuel also allows a radically improved fuel cycle technology. Pyroprocessing, which utilizes high temperatures and molten salt and molten metal solvents, can be advantageously utilized for processing metal fuels because the product is metal suitable for fabrication into new fuel elements. Direct production of a metal product avoids expensive and cumbersome chemical conversion steps that would result from use of the conventional Purex solvent extraction process. The key step in the IFR process is electrorefining, which provides for recovery of the valuable fuel constituents, uranium and plutonium, and for removal of fission products. A notable feature of the IFR process is that the actinide elements accompany plutonium through the process. This results in a major advantage in the high-level waste management

    Modifications to the Hot Fuel Examination Facility-South (HFEF/S) have been in progress since mid-1988 to ready the facility for demonstration of the unique Integral Fast Reactor (IFR) pyroprocess fuel cycle. This paper updates the last report on this subject to the American Nuclear Society and describes the progress made in the modifications to the facility and in fabrication of the new process equipment. The IFR is a breeder reactor, which is central to the capability of any reactor concept to contribute to mitigation of environmental impacts of fossil fuel combustion. As a fast breeder, fuel of course must be recycled in order to have any chance of an economical fuel cycle. The pyroprocess fuel cycle, relying on a metal alloy reactor fuel rather than oxide, has the potential to be economical even at small-scale deployment. Establishing this quantitatively is one important goal of the IFR fuel cycle demonstration

    A modeling and simulation methodology was proposed in order to implement the dynamic material flow of the pyroprocess. Since the static mass balance provides the limited information on the material flow, it is hard to predict dynamic behavior according to event. Therefore, a discrete event system (DES)-based model named, PyroFlow, was developed at the Korea Atomic Energy Research Institute (KAERI). PyroFlow is able to calculate dynamic mass balance and also show various dynamic operational results in real time. By using PyroFlow, it is easy to rapidly predict unforeseeable results, such as throughput in unit process, accumulated product in buffer and operation status. As preliminary simulations, bottleneck analyses in the pyroprocess were carried out and consequently it was presented that operation strategy had influence on the productivity of the pyroprocess.

    For the pyroprocessing facility to be commercialized in future, current regulations should be evaluated and developed in advance, based on the new types of nuclear materials in the facility. Physical protection system, especially, requires reasonable and reliable categorization of nuclear materials, to prevent from the theft of nuclear materials. In this paper, therefore, current categorization methods of nuclear material are investigated and applied to the pyroprocessing facility. After inconsistencies and gaps are found among methods, they are compared and discussed based on eight considering points (i.e, degrees of attractiveness, levels of category, discount factor, physical barriers, chemical barriers, isotopic barriers, radiological barriers, and capabilities of adversaries), to roughly suggest a new method for categorization. Current categorization methods of nuclear material, including IAEA's INFCIRC/225, U.S. DOE's method, newly expected U.S. NRC's method, FOM, and Bunn's approach, are different and can bring inconsistencies of physical protection requirements. The gap among methods will be significant if advanced fuel cycles are applied to them for the future. For example, the categorization results of 5 target materials in pyroprocessing facility show clear inconsistencies, while TRU ingot is considered the most attractive material. To resolve inconsistencies, it is necessary to determine new method suitable to pyroproessing facility, by considering the effects of eight points (i.e, degrees of attractiveness, levels of category, discount factor, physical barriers, chemical barriers, isotopic barriers, radiological barriers, and capabilities of adversaries)

    In this report, pyro processing facility concepts suggested by US, Japan, and Republic of Korea have been summarized and analyzed, and the determination principles were established to determine a reference pyro processing facility concept. Three proposals for a reference pyro processing facility concept were suggested based on these principles. The 1st proposal is based on the GEN-IV PR/PP model except the metal fuel fabrication process. It may be possible to later add the metal fuel fabrication process, UO2 recovery process of Japan, and continuous electrorefining process invented in Republic of Korea to be the generic model including all pyroprocessing facility concepts in the world. The 2nd proposal is based on INL and ANL model which is simple for the most part and has basic essential processes. The 3rd proposal is determined to be the ESPF of KAERI, which is almost identical with that of the 2nd proposal except in regards to utilization of an input accountability tank and continuous electrorefining process and the 3rd proposal is planned to be realized in 7 years. After the review of the IAEA and discussions at 3rd Working Group Meeting held in IAEA headquarters, the 3rd proposal has been determined as the final version of a reference pyroprocessing facility concept

    Full Text Available Pyroprocessing, which is a dry recycling method, converts spent nuclear fuel into U (Uranium/TRU (TRansUranium metal ingots in a high-temperature molten salt phase. This paper provides the unit process cost of a pyroprocess facility that can process up to 10 tons of pyroprocessing product per year by utilizing the process costing method. Toward this end, the pyroprocess was classified into four kinds of unit processes: pretreatment, electrochemical reduction, electrorefining and electrowinning. The unit process cost was calculated by classifying the cost consumed at each process into raw material and conversion costs. The unit process costs of the pretreatment, electrochemical reduction, electrorefining and electrowinning were calculated as 195 US$/kgU-TRU, 310 US$/kgU-TRU, 215 US$/kgU-TRU and 231 US$/kgU-TRU, respectively. Finally the total pyroprocess cost was calculated as 951 US$/kgU-TRU. In addition, the cost driver for the raw material cost was identified as the cost for Li3PO4, needed for the LiCl-KCl purification process, and platinum as an anode electrode in the electrochemical reduction process.

    2013-10-01

    Full Text Available Over the course of a decade-long research programme, the Korea Atomic Energy Research Institute (KAERI has developed several remote handling systems for use in pyroprocessing research facilities. These systems are now used successfully for the operation and maintenance of processing equipment. The most recent remote handling system is the bridge-transported dual arm servo-manipulator system (BDSM, which is used for remote operation at the world's largest pyroprocess integrated inactive demonstration facility (PRIDE. Accurate and reliable servo-control is the basic requirement for the BDSM to accomplish any given tasks successfully in a hotcell environment. To achieve this end, the hardware and software of a digital signal processor-based remote control system were fully custom-developed and implemented to control the BDSM. To reduce the residual vibration of the BDSM, several input profiles, including input shaping, were carefully chosen and evaluated. Furthermore, a time delay controller was employed to achieve good tracking performance and systematic gain tuning. The experimental results demonstrate that the applied control algorithms are more effective than conventional approaches. The BDSM successfully completed its performance tests at a mock-up and was installed at PRIDE for real-world operation. The remote handling system at KAERI is expected to advance the actualization of pyroprocessing.

    In this research, we developed a plan for experimental validation of one of the computer models developed for ER process modeling, i. e., the ERAD code. Several candidate surrogate materials are selected for the experiment considering the chemical and physical properties. Molten salt-based pyroprocessing technology is being examined internationally as an alternative to treat spent nuclear fuel over aqueous technology. The central process in pyroprocessing is electrorefining(ER) which separates uranium from transuranic elements and fission products present in spent nuclear fuel. ER is a widely used process in the minerals industry to purify impure metals. Studies of ER by using actual spent nuclear fuel materials are problematic for both technical and political reasons. Therefore, the initial effort for ER process optimization is made by using computer models. A number of models have been developed for this purpose. But as validation of these models is incomplete and often times problematic, the simulation results from these models are inherently uncertain.

  17. Development of a methodology to evaluate material accountability in pyroprocess

    Science.gov (United States)

    Woo, Seungmin

    This study investigates the effect of the non-uniform nuclide composition in spent fuel on material accountancy in the pyroprocess. High-fidelity depletion simulations are performed using the Monte Carlo code SERPENT in order to determine nuclide composition as a function of axial and radial position within fuel rods and assemblies, and burnup. For improved accuracy, the simulations use short burnups step (25 days or less), Xe-equilibrium treatment (to avoid oscillations over burnup steps), axial moderator temperature distribution, and 30 axial meshes. Analytical solutions of the simplified depletion equations are built to understand the axial non-uniformity of nuclide composition in spent fuel. The cosine shape of axial neutron flux distribution dominates the axial non-uniformity of the nuclide composition. Combined cross sections and time also generate axial non-uniformity, as the exponential term in the analytical solution consists of the neutron flux, cross section and time. The axial concentration distribution for a nuclide having the small cross section gets steeper than that for another nuclide having the great cross section because the axial flux is weighted by the cross section in the exponential term in the analytical solution. Similarly, the non-uniformity becomes flatter as increasing burnup, because the time term in the exponential increases. Based on the developed numerical recipes and decoupling of the results between the axial distributions and the predetermined representative radial distributions by matching the axial height, the axial and radial composition distributions for representative spent nuclear fuel assemblies, the Type-0, -1, and -2 assemblies after 1, 2, and 3 depletion cycles, is obtained. These data are appropriately modified to depict processing for materials in the head-end process of pyroprocess that is chopping, voloxidation and granulation.

    Various advanced and more easily safeguard-able reprocessing technologies have been proposed and are currently at different stages of development. This paper briefly analyses two proposed next generation reprocessing technologies, i. e. UREX+1a and pyroprocessing. It goes on to suggest various measures that can be taken to safeguard these technologies against nuclear proliferation. Due to the significant proliferation risks associated with PUREX, more proliferation resistant technologies are required in spent fuel reprocessing. UREX+1a and pyroprocessing can be suitable replacements since Pu is not separated from other TRUs after reprocessing. Implementations of technology specific safeguard measures can help enhance the proliferation resistance of these technologies. Since there is no technology which is foolproof, a MUF uncertainty estimation/quantification technology needs to be developed. These uncertainty estimates can then be used in a safeguards probabilistic risk assessment (PRA) system to quantify the risks associated with a particular reprocessing technology. To further safeguard these technologies, additional safeguard measures are needed for defense in depth. This may include implementation of multiple, independent, and redundant layers of defense such that no single layer, no matter how robust, is solely relied upon. Quantification of safeguard uncertainties related to UREX+1a and pyroprocessing can be used to benchmark these technologies against PUREX and between themselves for policy making

    Full Text Available The Canadian transition to IFRS provides a valuable IFRS learning opportunity. The Canadian transition and implementation of IFRS provides a unique opportunity to examine the conversion of financial reporting from a similar set of financial reporting rules as U.S. GAAP in a similar economic and business environment. The implementation and adoption of IFRS is not a monolithic event. Our ability to comprehensively understand and assess IFRS requires transparent disclosures such as those mandated by IFRS 1 and disaggregation of the equity components to observe and measure the impact of IFRS as it pertains to discretionary management implementation choices, material reclassifications, and GAAP-to-GAAP differences. Comprehensive knowledge of IFRS 1, First Time Adoption of International Financial Reporting Standards is crucial to our ability to assess the transitory and future impact of IFRS. IFRS 1 sets the precedent for financial reporting under IFRS, overrides transitional provisions included in other IFRS, and prescribes detailed disclosures. This detailed “rules-based” standard permits discretionary management policy choices which have material impact on transitory reporting as well as future financial results.

  2. The IFR status and prospects

    The integral fast reactor (IFR) concept consists of a metal-fueled, liquid-metal-cooled fast reactor with its associated pyrometallurgical recovery and recycle of plutonium and higher actinides. The feasibility and operational stability of a liquid-metal-cooled fast reactor has been amply demonstrated in many countries. A comprehensive understanding of the irradiation effects on metal fuels permits extremely high fuel burnup without failures. Interest in the IFR concept grew rapidly when (in 1986) the benign response of the IFR was demonstrated by deliberately putting Experimental Breeder Reactor II (EBR-II) through unprotected loss-of-flow and loss-of-heat-sink transients; these transients were comfortably controlled by the inherent feedback of the system

    Highlights: • Pyroprocessing is a complicated batch-type operation. • Discrete event system modeling was used to create an integrated operation model. • Simulation showed that could be accomplished. • The dynamic material flow helps us understand the process operation. • We showed that complex material flow could be simulated in terms of mass balance. - Abstract: Pyroprocessing is a complicated batch-type operation, involving a highly complex material flow logic with a huge number of unit processes. Discrete event system modeling was used to create an integrated operation model for which simulation showed that dynamic material flow could be accomplished to provide considerable insight into the process operation. In the model simulation, the amount of material transported upstream and downstream in the process satisfies a mass balance equation while considering the hold-up incurred by every batch operation. This study also simulated, in detail, an oxide reduction group process embracing electrolytic reduction, cathode processing, and salt purification. Based on the default operation scenario, it showed that complex material flows could be precisely simulated in terms of the mass balance. Specifically, the amount of high-heat elements remaining in the molten salt bath is analyzed to evaluate the operation scenario.

    Three different methods have been used to condition chloride salt wastes coming from pyro-processes. Two of them allow to synthesise sodalite, a naturally occurring mineral containing chlorine: the former, starting from Zeolite 4A, which transforms the zeolite into sodalite; the latter, which starts from kaolinite, giving sodalite as well. In addition, a new matrix, termed SAP (SiO 2 -Al 2 O 3 -P 2 O 5 ), has been synthesised. It is able to form different mineral phases which occlude fission metals. The products from the different processes have been fully characterised. In particular the chemical durability of the final waste forms has been determined using the standard product consistency test. According to the results obtained, SAP seems to be a promising matrix for the incorporation of chloride salt wastes from pyro-processes. Financial support from the Nuclear Fission Safety Programme of the European Union (projects ACSEPT, contract FP7-CP-2007- 211 267, and SACSESS, Collaborative Project 323282), as well as from Italian Ministry for Economic Development (Accordo di Programma: Piano Annuale di Realizzazione 2008-2009) is gratefully acknowledged.

    The author has identified several pyrometallurgical processes for the conceptual ATW waste treatment cycle. These processes include reductive extraction, electrowinning and electrorefining, which constitute some versatile treatment cycles for liquid-metal based and molten-salt based waste forms when they are properly integrated. This paper examines the implementation of these processes and the achievable separations for some typical species. The author also presents a simple analysis of the processing rates limited by mass diffusion through a thin hydrodynamic boundary layer. It is shown that these processes can be realized with compact and efficient devices to meet the ATW demand for the periodic feeding and cleaning of the waste

This study also extends the current literature by examining the interacting effect between IFRS adoption and family ownership on earnings management. Data are obtained from Bloomberg database and Malaysia stock exchange for the period 2010-2013. Using multiple regression analysisis, this study found that firms exhibit less earnings management after IFRS adoption. This finding is consistent with the argument that IFRS are claimed to be high-quality accounting standards. However,this study find no evidence to support that family ownership and interaction between IFRS and family ownership negatively affect earnings management.

    Treatment of spent nuclear fuel at Argonne National Laboratory consists of a pyroprocessing scheme in which the development of suitable waste forms is being advanced. Of the two waste forms being proposed, metal and mineral, the production of the metal waste form utilizes induction melting to stabilize the waste product. Alloying of metallic nuclear materials by induction melting has long been an Argonne strength and thus, the transition to metallic waste processing seems compatible. A test program is being initiated to coalesce the production of the metal waste forms with current induction melting capabilities

    Full Text Available This study investigates how the mandatory adoption of International Financial Reporting Standards (IFRS affects the contractual benefits of using accounting information to determine executive compensation in China. After controlling for firm and corporate governance characteristics, we find strong evidence supporting the positive role of mandatory IFRS adoption on the accounting-based performance sensitivity of executive compensation. Subsample analysis suggests that improvements in accounting-based performance sensitivity after IFRS adoption differ across regions with various levels of institutional quality and across firms that are affected to a different extent by the adoption. Additional analysis supports the argument that the positive effects of IFRS adoption on the use of accounting performance in executive compensation are driven by the reduction in accounting conservatism associated with IFRS adoption.

    In the frame of Generation IV reactors a renewed interest in pyro-processing of spent nuclear fuel is underway. Molten chloride salt waste arising from the recovering of uranium and plutonium through pyro-processing is one of the problematic wastes for direct application of vitrification or ceramization. In this work, Sodalite and SAP have been evaluated and compared as potential matrices for confinement of spent chloride salt waste coming from pyro-processing. To this aim Sodalite and SAP were synthesized both in pure form and mixed with different glass matrices, i.e. commercially available glass frit and borosilicate glass. The confining matrices were loaded with mixed chloride salts to study their retention capacities with respect to the elements of interest. The matrices were characterized and leached for contact times up to 150 days at room temperature and at 90 °C. SEM analyses were also performed in order to compare the matrix surface before and after leaching. Leaching results are discussed and compared in terms of normalized releases with similar results reported in literature. According to this comparative study the SAP matrix with glass frit binder resulted in the best matrix among the ones studied, with respect to retention capacities for both matrix and spent fuel elements.

    The Integral Fast Reactor (IFR), which Argonne National Laboratory is developing, is an innovative liquid metal breeder reactor that uses metallic fuel and has a close coupled fuel recovery process. A pyrochemical process is used to separate the fission products from the actinide elements. These actinides are used to make new fuel for the reactor. As part of the overall IFR development program, Argonne has refurbished an existing Fuel Cycle Facility at ANL-West and is installing new equipment to demonstrate the remote reprocessing and fabrication of fuel for the Experimental Breeder Reactor II (EBR-II). During this demonstration the wastes that are produced will be treated and packaged to produce waste forms that would be typical of future commercial operations. These future waste forms would, assuming Argonne development goals are fulfilled, be essentially free of long half-life transuranic isotopes. Promising early results indicate that actinide extraction processes can be developed to strip these isotopes from waste stream and return them to the IFR type reactors for fissioning. 1 fig

Moreover, it is estimated that the shale gas can be used for about 60 years, which is comparable to the period estimated for oil deposits. Another concern is that the climate may change due to the discharge of harmful gas produced during the gas extraction process. PRIDE facility producing 10 ton/year uranium ingot was set as the cost object for the cost estimation, and it was possible to increase cost calculation's accuracy level since labor cost and expenses incurred in this facility were the costs incurred in actuality. In the end, First-In, First Out process costing method was used to calculate the pretreatment cost of pyroprocess. According to the cost calculation results, the pretreatment cost was estimated as $195/kgHM and the cost share of the pretreatment of pyroprocess was calculated as 20%.

  3. How has IFRS impacted financial reporting for unlisted entities?

    Elina Haapamäki

    2018-03-01

    Full Text Available This paper addresses the question whether adoption of International Financial Reporting Standards (IFRS is associated with low earnings management in unlisted companies in three European countries. Therefore, this paper investigates whether companies that have adopted IFRS voluntarily engage significantly less in earnings management compared to companies that have not adopted IFRS. Moreover, this study examines firm-specific incentives and their role in the adoption decision within different institutional settings. The distribution of earnings is analyzed to discover whether companies have managed their earnings. Logistic regression analysis is used to examine the firm-specific incentives. Empirical findings reveal that in sample of unlisted firms using IFRS the distribution of earnings is smoother. Thus, the results provide supporting evidence for the adoption of IFRS. Moreover, results of this study provide relatively good empirical support for statements that large unlisted firms with foreign owners and that are profitable are more likely to adopt IFRS voluntarily. However, the firm-specific incentives play different role in the adoption decision process in weak institutional settings compared to strong institutional settings.

  4. Effects of IFRS adoption on tax avoidance

    Directory of Open Access Journals (Sweden)

    Renata Nogueira Braga

    Full Text Available ABSTRACT This study investigates the association between mandatory International Financial Reporting Standards (IFRS adoption and corporate tax avoidance. In this study, tax avoidance is defined as a reduction in the effective corporate income tax rate through tax planning activities, whether these are legal, questionable, or even illegal. Three measures of tax avoidance are used and factors at the country and firm level (that have already been associated with tax avoidance in prior research are controlled. Using samples that range from 9,389 to 15,423 publicly-traded companies from 35 countries, covering 1999 to 2014, it is found that IFRS adoption is associated with higher levels of corporate tax avoidance, even when the level of book-tax conformity required in the countries and the volume of accruals are controlled, both of which are considered potential determinants of this relationship. Furthermore, the results suggest that after IFRS adoption, firms in higher book-tax conformity environments engage more in tax avoidance than firms in lower book-tax conformity environments. It is also identified that engagement in tax avoidance after IFRS adoption derives not only from accruals management, but also from practices that do not involve accruals. The main conclusion is that companies engage more in tax avoidance after mandatory IFRS adoption.

    Full Text Available IFRS for SMEs were adopted in July 2009 as a result of efforts to harmonize financial reporting for SMEs. These standards are based on the same principles as full standards. The aim is, compared to full IFRS reporting of these businesses, to significantly simplify, mainly from the reason that the strict application of the principles of the full standards does not excessively financially and administratively burden smaller accounting entity. Field of identifying, recording and reporting of intangible assets except goodwill is an important field in which the methodology is substantially different. In the pre­sent paper there is documented on the example the impact of different methods for recording of internally generated intangible assets in the both systems into balance sheet and profit or loss and into the selected indicators of financial analysis. Definition of issues that may arise during the transition from the IFRS for SMEs to full IFRS and vice versa, in the context of drafting the opening balance sheet is another field to which the paper is dedicated.

    Full Text Available The study aims to examine the perception of key actors regarding the costs and benefits that result from adopting International Financial Reporting Standards (IFRS in Ukraine. Design/Methodology/Approach – The authors conducted a questionnaire survey in order to identify perceptions of financial managers of Ukrainian listed firms regarding the benefits and the costs associated with transition to IFRS. Our results showed that IFRS implementation impacts on internal reporting quality, the relationship with customers, creditors and shareholders, the access to international markets and external financing. It also indicated that financial managers have serious concerns about implementation costs related to the introduction of IFRS. These costs relate to training, instruction on IFRS adoption and translation of current IFRS, changes in software systems, double purpose accounting and deadlines for IFRS adoption and consulting services. Whilst this research has established a general model that consists of six factors, affecting IFRS relevance to Ukraine, the extent of interrelations between these factors is not clear. Thus, it may be of a great interest for future research to explore this issue in more detail and, in particular, conduct empirical research to determine the extent of interdependency between six factors in the model. The results and conclusions of this research can be of a great interest to policy makers and business practitioners since all public companies in Ukraine are obliged to adopt IFRS from 2012. It might be of interest to conduct this research on results of mandatory implementation of IFRS in Ukraine while taking into account the circumstances that suggested almost no relevance of the international accounting standards to the country at the moment of their application. This is the first metrical study that discusses the relevance of IFRS to Ukraine’s national needs

    A large quantity of actinide elements is present in irradiated Light Water Reactor (LWR) fuel that is stored throughout the world. Because of the high fission-to-capture ratio for the transuranium (TRU) elements with the high-energy neutrons in the metal-fueled Integral Fast Reactor (IFR), that reactor can consume these elements effectively. The stored fuel represents a valuable resource for an expanding application of fast power reactors. In addition, removal of the TRU elements from the spent LWR fuel has the potential for increasing the capacity of a high-level waste facility by reducing the heat loads and increasing the margin of safety in meeting licensing requirements. Argonne National Laboratory (ANL) is developing a pyrochemical process, which is compatible with the IFR fuel cycle, for the recovery of TRU elements from LWR fuel. The proposed product is a metallic actinide ingot, which can be introduced into the electrorefining step of the IFR process. The major objective of the LWR fuel recovery process is high TRU element recovery, with decontamination a secondary issue, because fission product removal is accomplished in the IFR process. The extensive pyrochemical processing studies of the 1960s and 1970s provide a basis for the design of possible processes. Two processes were selected for laboratory-scale investigation. One is based on the Salt Transport Process studied at ANL for mixed-oxide fast reactor fuel, and the other is based on the blanket processing studies done for ANL's second Experimental Breeder Reactor (EBR-2). This paper discusses the two processes and is a status report on the experimental studies. 5 refs., 2 figs., 2 tabs

    Time-dependent sensitivity techniques, which have been used in the past for standard reactor applications, have been adapted to calculate the impact of data uncertainties in radiotoxicity evaluations. The methodology has been applied to different strategies of radioactive waste management connected with the EFR and IFR reactor fuel cycles. Results are provided in terms of sensitivity coefficients to basic data (cross sections and decay constants), and uncertainties on global radiotoxicity at different times of storing after discharge. 6 refs., 6 figs., 9 tabs

    The master plan of permanent nuclear waste repository had been published in South Korea. The high-level nuclear waste repository should be available in 2053. In this study, six possible nuclear waste forms are simulated by Helium ions. The geological repository is comparative easy and cheap considering the international nuclear act of the nuclear nonproliferation treaty (NPT). How ever, there could be some new technologies of the nuclear waste treatment like the pyroprocessing. Transmutation is another option, which is very expensive with current technology.

    Full Text Available This study investigates the implications of the gap between International Financial Reporting Standards (IFRS and New Zealand International Financial Reporting Standards (NZIFRS on financial reporting transparency, accountability and corporate fraud. Content analysis of IFRS and NZIFRS was carried out to determine if there are differences between IFRS and NZIFRS. Four IFRS, namely IAS 12, IFRS 13, IFRS 15, IAS 17 and IFRS 16 were analysed on the basis of adoption concessions and Reduced Disclosure Regime (RDR for tier 1 and 2 entities. The findings from these standards led to a review of the associated IFRS to further understand the implications of the standards on financial reporting transparency and decline in incidences of corporate fraud. We found that the difference between IFRS and NZIFRS lies in the financial reporting framework for tier 2 entities. However, we did not find a difference between IFRS and NZIFRS for entities in tier 1 but we identified a decline in incidences of corporate fraud after IFRS was adopted. We further identified the presence of information asymmetry for tier 2 which is capable of retaining Generally Accepted Accounting Principles (GAAPs. These differences may increase the incidence of corporate fraud among the entities in tier 2 of External Reporting Framework. This is due to an excessive concession from IFRS implementation in New Zealand.

    Full Text Available In our globalized world, accounting has followed the trend and it has imposed comparability norms in order to adjust to everyday economic transactions. The International Financial Reporting Standards are a set of accounting standards developed by a non-profit organization called IASB (International Accounting Standards Board. This set of standards is applied in many countries all over the world, and Romania is one of them. The advantages of IFRS are well known and recognized, but the path of IFRS adoption is not always smooth. This paper aims to present the limits and the challenges encountered by the companies which apply IFRS in their financial reports.

    2010-09-01

    The Idaho National Laboratory has undertaken an effort to develop a standard safeguards approach for international commercial pyroprocessing facilities. This report details progress for the fiscal year 2010 effort. A component by component diversion pathway analysis has been performed, and has led to insight on the mitigation needs and equipment development needed for a valid safeguards approach. The effort to develop an in-hot cell detection capability led to the digital cloud chamber, and more importantly, the significant potential scientific breakthrough of the inverse spectroscopy algorithm, including the ability to identify energy and spatial location of gamma ray emitting sources with a single, non-complex, stationary radiation detector system. Curium measurements were performed on historical and current samples at the FCF to attempt to determine the utility of using gross neutron counting for accountancy measurements. A solid cost estimate of equipment installation at FCF has been developed to guide proposals and cost allocations to use FCF as a test bed for safeguards measurement demonstrations. A combined MATLAB and MCNPX model has been developed to perform detector placement calculations around the electrorefiner. Early harvesting has occurred wherein the project team has been requested to provide pyroprocessing technology and safeguards short courses.

    Full Text Available Accounting standards that are mostly compatible with International Financial Reporting Standards (IFRS are required for consolidatedfinancial statements of all Turkish listed firms starting from 2005 fiscal year end. Before that, financial reporting in Turkey was closely related to taxreporting. Until 2003, all Turkish listed firms were preparing their financial statements in accordance with the local standards issued by the CapitalMarket Board of Turkey. In this study, I examine the relative and incremental value relevance of earnings and the book value of equity under CapitalMarket Board (CMB Accounting Standards (2001-2002 and under IFRS (2005-2006 for Turkish listed firms. I compare these two periods toinvestigate whether the mandatory adoption of IFRS increase relevance of earnings and book value of equity which are accepted as proxies ofaccounting quality. I find evidence that the value relevance of earnings and book value of equity has increased significantly after adopting IFRS. Inaddition, I find that the incremental value relevance of earnings increased between the CMB accounting standards period and the IFRS period.However, the incremental value relevance of book value of equity degreased in the same period.

    Full Text Available In recent time, there were done marked changes in IAS/IFRS, changes in existing rules. Fifteen standards of IAS have been amended just before the end of 2003 and in course of the first quarter of the year 2004 updating of other standards IAS has been done. The requirement of changes hangs together, among others, also with the recent affairs about the bankruptcies of big companies. In this connection, accelerated and turning changes are proceeding in EU. Since 2005 every EU listed company has to prepare the consolidated financial statements in accordance with IFRS/IAS. Vast survey on the impacts of IFRS adoption was carried by Mazars in 2005. 25 Czech companies have been also interviewed within the study. These Czech companies have exhibit a strong mastery and readiness for the conversion and transition process. Such a summary is quite unwonted in a number of perspectives. But the aim of the author is not to question the study. In the Czech environment, the specific facts in the field of financial reporting and accounting are given. Following these specifics, the truth is that preparing the financial statements in accordance with IFRS/IAS brings undoubtedly valuation and technical entanglements for which the process is costly.

  4. The benefits and costs of IFRS implementation in Poland – the investors’ perspective

    Directory of Open Access Journals (Sweden)

    Katarzyna Klimczak

    2017-12-01

    Full Text Available A number of earlier studies analysed the process as well as the consequences of implementing Interna- tional Financial Reporting Standards (IFRS in Poland. Prior research concentrated mainly on the impact of IFRS implementation on the financial reporting of companies in Poland and market reaction to the application of IFRS. Not much attention has been given to the attitudes of different groups of accounting information users and other interested parties towards the change of reporting standards in Poland. The aim of this study is to determine how investors perceive IFRS adoption by firms in Poland. Do they see any advantages of financial statements being prepared under IFRS and not under the Polish Accounting Act after more than 10 years from the introduction of the mandatory application of IFRS for certain companies? Has the application of IFRS to the preparation of financial statements increased the scope of useful financial information for investors? Has the quality of the information presented in financial state- ments changed in any way? Finally, should the mandate to use IFRS in Poland be extended? A survey was used to obtain answers to the above questions. In the opinion of investors, the adoption of IFRS for firms has increased the comparability and usefulness of financial statements and also enhanced the pro- tection of their interests but it has not contributed to their investment decisions or the possibility to make profit forecasts. The switch to IFRS – in the perception of the respondents – failed to reduce the infor- mation asymmetry between the external and internal users of accounting information. The impact of chang- ing accounting standards on capital market liquidity failed to be unequivocally assessed.

    2017-03-01

    Full Text Available Abstract The purpose of this paper is to examine the relationship between the mandatory adoption of IFRS/IAS and the information content of earnings in the European Union. More accurately, this study aims to determine if the effect of IFRS adoption on the level of information asymmetry, apprehended by the cost of capital and the financial analysts’ forecasts, is immediate or delayed. Based on a longitudinal study, we find evidence that for the two first years of adoption, international standards reduces significantly the cost of capital and the dispersion of the financial analysts’ forecasts. Furthermore, the magnitude of this effect increases with increasing the number of years after IFRS adoption. The findings further show that the effect of IFRS adoption on financial analysts’ errors is not immediate and that the errors decrease from the third year following the date of the first adoption. Overall, the findings of this study highlight the importance of adopting IFRS in the reduction of information asymmetry.

    Full Text Available On the last two decades, financial reporting area has suffered lot of changes in order to respond properly to the dynamics of the economic system characterized by continuous process of globalization, international capitalization, and multinational corporations increasing economic impact. Implementation of IFRSs has been positively perceived by both preparers and users from quality of financial information improvement point of view and economic effects perspective as well. Romanian regulators have decided to align to the EU accounting legislation by adopting IFRS for the consolidated accounts preparation. Furthermore, they have chosen to extend IFRS use to individual financial statements in case of all listed companies. In this study we will provide evidence using an index of conservatism that there are small changes on the financial accounts pre IFRS adoption versus post IFRS adoption at the statutory financial statements level. This evidence is actually reflecting the continuous efforts of Romanian regulator to harmonize the local accounting regulation with IFRS.

  10. Measurement of Irradiated Pyroprocessing Samples via Laser Induced Breakdown Spectroscopy

    The primary objective of this research is to develop an applied technology and provide an assessment to remotely measure and analyze the real time or near real time concentrations of used nuclear fuel (UNF) dissolute in electrorefiners. Here, Laser-Induced Breakdown Spectroscopy (LIBS), in UNF pyroprocessing facilities will be investigated. LIBS is an elemental analysis method, which is based on the emission from plasma generated by focusing a laser beam into the medium. This technology has been reported to be applicable in the media of solids, liquids (includes molten metals), and gases for detecting elements of special nuclear materials. The advantages of applying the technology for pyroprocessing facilities are: (i) Rapid real-time elemental analysis|one measurement/laser pulse, or average spectra from multiple laser pulses for greater accuracy in < 2 minutes; (ii) Direct detection of elements and impurities in the system with low detection limits|element specific, ranging from 2-1000 ppm for most elements; and (iii) Near non-destructive elemental analysis method (about 1 g material). One important challenge to overcome is achieving high-resolution spectral analysis to quantitatively analyze all important fission products and actinides. Another important challenge is related to accessibility of molten salt, which is heated in a heavily insulated, remotely operated furnace in a high radiation environment with an argon atmosphere.

    Full Text Available Small and medium sized companies have very important position in the EU economy, mainly in the area of employment. Their activities on the internal market are limited by a great deal of obstacles. The most important obstacles can be considered different national financial reporting and tax systems.IASB published an International Financial Reporting Standard (IFRS designed for use by small and medium-sized entities (SMEs.The IFRS for SME is expressly designed to meet the financial reporting needs of entities that (a do not have public accountability and (b publish general purpose financial statements for external users. This standard could be a suitable instrument for the SME accounting harmonization. The aim of the paper is to analyze the problems connected with the harmonization of accounting legislation used by SMEs in EU countries especially in the Czech Republic. In the frame of methodology the empirical research was used. The author has distributed questionnaires to the enterprises in the Czech Republic, selected according to their size and the field of activity. Comment letters of 210 respondents from 26 EU Member States were used for evaluation possibilities of the IFRS for implementation to national legislation.Based on the results of empirical research some problems could arise with the IFRS for SME application. Based on the questionnaires, respondents are highly interested in the costs and gains of IFRS for SME application. The gains should exceed the costs of IFRS for SME application.

    Ku, J.Y.; Chang, L.K.; Mohr, D.

    1994-01-01

    Thermal-hydraulic uncertainty factors for Integral Fast Reactor (IFR) driver fuels have been determined based primarily on the database obtained from the predecessor fuels used in the IFR prototype, Experimental Breeder Reactor II. The uncertainty factors were applied to the channel factors (HCFs) analyses to obtain separate overall HCFs for fuel and cladding for steady-state analyses. A ''semistatistical horizontal method'' was used in the HCFs analyses. The uncertainty factor of the fuel thermal conductivity dominates the effects considered in the HCFs analysis; the uncertainty in fuel thermal conductivity will be reduced as more data are obtained to expand the currently limited database for the IFR ternary metal fuel (U-20Pu-10Zr). A set of uncertainty factors to be used for transient analyses has also been derived

    Full Text Available In 2009, 117 countries all over the world allowed to prepare financial statements according to International Financial Reporting Standards (IFRS including the Czech Republic. Between Czech General Accepted Accounting Principles (CZ GAAP and IFRS are some differences involving reporting of noncurrent fixed assets, leasing, construction contracts etc. Using different accounting procedure we can get different value of assets and assets are one component that is used to calculate the financial performance indicators. Those indicators are then used by investors to assess the financial performance of companies and the application of IFRS instead of CZ GAAP can lead to distinct presentation of enterprise performance. In this paper we examine the influence of construction contract reporting using IFRS and CZ GAAP on financial indicators. IFRS leads to more stable development during the period when the project is in progress. In the last year when the project is finished the figures of both ratios (ROA and Z-score are getting worse which is due to the lower percentage of the construction that is built in this year.

    Pyroprocessing is are processing method for managing and reusing used nuclear fuel (UNF) by dissolving it in an electrorefiner with a molten alkali or alkaline earth chloride salt mixture while avoiding wet reprocessing. Pyroprocessing UNF with a LiCl–KCl eutectic salt releases the fission products from the fuel and generates a variety of metallic and salt-based species, including rare earth (RE) chlorides. If the RE-chlorides are converted to oxides, borosilicate glass is a prime candidate for their immobilization because of its durability and ability to dissolve almost any RE waste component into the glass matrix at high loadings. Crystallization that occurs in waste glasses as the waste loading increases may complicate glass processing and affect the product quality. This work compares three types of borosilicate glasses in terms of liquidus temperature (T{sub L}): the International Simple Glass designed by the International Working Group, sodium borosilicate glass developed by Korea Hydro and Nuclear Power, and the lanthanide aluminoborosilicate (LABS) glass established in the United States. The LABS glass allows the highest waste loadings (over 50 mass% RE{sub 2}O{sub 3}) while possessing an acceptable chemical durability. - Highlights: • We investigated crystallization in borosilicate glasses containing rare earth oxides. • New crystallinity and durability data are shown for glasses proposed in the literature. • Both liquidus temperature and chemical durability increased as the waste loading increased.

    Isoflavone reductase (IFR) is an enzyme involved in the biosynthetic pathway of isoflavonoid phytoalexin in plants. IFRs are unique to the plant kingdom and are considered to have crucial roles in plant response to various biotic and abiotic environmental stresses. Here, we report the characterization of a novel member of the soybean isoflavone reductase gene family GmIFR. Overexpression of GmIFR transgenic soybean exhibited enhanced resistance to Phytophthora sojae. Following stress treatments, GmIFR was significantly induced by P. sojae, ethephon (ET), abscisic acid (placeCityABA), salicylic acid (SA). It is located in the cytoplasm when transiently expressed in soybean protoplasts. The daidzein levels reduced greatly for the seeds of transgenic plants, while the relative content of glyceollins in transgenic plants was significantly higher than that of non-transgenic plants. Furthermore, we found that the relative expression levels of reactive oxygen species (ROS) of transgenic soybean plants were significantly lower than those of non-transgenic plants after incubation with P. sojae, suggesting an important role of GmIFR might function as an antioxidant to reduce ROS in soybean. The enzyme activity assay suggested that GmIFR has isoflavone reductase activity.

    Full Text Available In 2007, Brazil adopted the International Financial Reporting Standards (IFRS. Studies involving publicly traded companies in different countries around the world indicate that these new standards tend to improve the information quality and make it more comparable and transparent. This study was aimed at verifying any changes in the earnings management levels after 2010 and whether this happened in function of the full adoption of the IFRS by the Brazilian publicly traded companies (except for financial institutions. The data were extracted from the three-monthly financial statements of the databases from Economática and the Brazilian Securities Commission for the period from 2006 till 2011. To achieve the research objectives, two tests were applied. The first showed that the average discretionary accruals, calculated through the Modified Jones Model, were lower after 2010. Next, the regression analysis was elaborated, using panel data with Newey-West’s correction. The results did not confirm the hypothesis that the adoption of the IFRS affected the earnings management level in the period under analysis, but showed that the size and indebtedness significantly explain the discretionary accruals, independently of the adoption of the IFRS. The results suggest that larger companies with a large proportion of own capital tend to produce higher quality reports, independently of the adoption of the IFRS.

    2011-01-01

    The data base for the pyroprocessing material flow and MUF uncertainty simulation has been implemented well. There is no error in the data base processing and it is relatively fast by using OLEDB and MySQL. The important issue is the data base size. In OLEDB the data base size is limited to 2 Gb. To reduce the data base size, we give an option for users to filter the input nuclides based on their masses and activities. A simulation program called PYMUS has been developed to study the pyroprocessing material flow and MUF. In the program, there is a data base system that controls the data processing in the simulation. The data base system consists of input data base, data processing, and output data base. The data base system has been designed in such a way to be efficient. One example is using the OLEDB and MySQL. The data base system is explained in detail in this paper. The result shows that the data base system works well in the simulation

    Full Text Available In a period when convergence is the main driving force of IASB and FASB programmes, who needs a comparison of the two sets of standards-IFRS issued by IASB and US GAAP issued by FASB? Arent they mainly the same after 5 years of hard work of those who establish the two sets of standards? The answer lies in the fact that mostly all people who work in a multinational company has to understand the present differences between these two sets of standards. A combination of the convergence of the national standards with the IFRS and the follow-up use of IFRS standards would mean that the two accounting languages from all over the world should be reduced rapidly only to IFRS and US GAAP. Although these two sets of standards are more and more similar to each other, they are not totally identical-yet. And until they become identical it will be necessary to state clearly and explain the differences that exist between them.

    The integral fast reactor (IFR) employs a reactor design that has inherent safety features. An important safety advantage is derived from its pool configuration, which facilitates passive decay heat removal and isolates the core from accidents that might occur elsewhere in the plant. The metal-alloy fuel has superior heat transfer properties compared to oxide fuels. While the IFR design has these inherent safety features, a complete analysis of reactor safety requires assessment of the consequences of the melting of the uranium alloy fuel in the core and the contact of molten core materials with sodium. A series of eight tests was conducted in which the fragmentation and interaction behavior of kilogram quantities of uranium-zirconium alloy in sodium was studied

    Vitrification of Tc wastes has been challenging because of the low solubility in the silicate glass and high volatility in the melting process. In previous studies, the measured solubility of Tc and Re was ⁓ 3000 ppm at 1000 .deg. C in low activity waste (LAW) glass. And retention of Tc has been reported within 12 - 77% during the borosilicate vitrification process. Tellurite glasses have been studied for halide waste immobilization due to low melting temperatures (Tm= 600-800 .deg. C) and flexibility of network with foreign ions. Tellurite glasses offered higher halide retention than borosilicate glasses. The structure of pure tellurite (TeO{sub 2}) consists of TeO{sub 4} trigonal bipyramids (tbp), but TeO{sub 4} units are converted to TeO{sub 3} trigonal pyramids (tp) having non-bridging oxygen (NBO) as the modifiers added. Objectives of this study are to investigate the tellurite glasses for Tc immobilization using Re as a surrogate. Retention and waste loading of Re were analyzed during the vitrification process of tellurite glass. We investigated local structures of Re ions in glasses by Raman and X-ray absorption spectroscopies. The tellurite glass was investigated to immobilize the Ca(TcO{sub 4}){sub 2}, surrogated by Ca(ReO{sub 4}){sub 2}. The average of Re retention in tellurite glass was 86%. The 7-day PCT results were satisfied with U.S requirement up to 9 mass% of Ca(ReO{sub 4}){sub 2} content. Re in the tellurite glass exists +7 oxidation state and was coordinated with 4 oxygen.

  9. The Impact of Financial Reporting Enforcement and IFRS Adoption on Executive Compensation

    DEFF Research Database (Denmark)

    Banghøj, Jesper; Marton, Jan; Plenborg, Thomas

    This study examines whether both IFRS adoption and the level of financial reporting enforcement impact the contractual usefulness of financial statements, as reflected in payperformance sensitivity. Using a sample of 8,440 executive year observations from 522 firms in 16 European countries we find....... This suggests that the impact of enforcement on pay‐performance sensitivity vanishes after the implementation of IFRS. These results indicate that IFRS dominate enforcement when it comes to the contractual usefulness of financial statements. The findings should be of interest to both enforcement authorities...... that when earnings are based on local GAAP, the payperformance sensitivity is positive and significant only when the level of enforcement is high. When earnings are based on IFRS, we find that the pay‐performance sensitivity is (equally) positive and significant across different levels of enforcement...

    Full Text Available The paper deals with the effects of IFRS adoption by a specific group of companies. It focuses on the so-called forced IFRS adopters, which are such private (non-listed companies that (a are forced to adopt the IFRS (because their parent prepares IFRS consolidated statements and simultaneously (b are not permitted by the regulatory framework of a given jurisdiction to apply the IFRS in their individual financial statements on a  voluntary basis. In particular, benefits and costs connected with the forced IFRS adoption by Czech private companies are assessed. The results, based on a  questionnaire survey among affected companies, confirm the intuitive presumption that accounting treatment of certain items significantly differs between Czech GAAP and IFRS, which requires the use of advanced methods for the conversion of financial statements. Regardless of which conversion method is used, perceptions of both benefits and appropriateness of incurred costs vary across entities. The benefit-to-cost ratio for the two most commonly used conversion methods (spreadsheets and dual accounting software is comparable, as the first method generates fewer benefits for lower costs and the second method is connected with more benefits, but at higher costs. Finally, the survey reveals that actual costs of IFRS adoption are higher than the expected costs regardless of the conversion method applied.

    Which nuclear fuel cycle option to deploy is of great importance in the sustainability of nuclear power. SFR fuel cycle employing pyroprocessing (named as Pyro- SFR Cycle) is one promising fuel cycle option in the near future. Radioactive waste generation is a key criterion in nuclear fuel cycle system analysis, which considerably affects the future development of nuclear power. High population with small territory is one special characteristic of ROK, which makes the waste management pretty important. In this study, particularly the amount of waste generation with regard to the promising advanced fuel cycle option was evaluated, because the difficulty of deploying an underground repository for HLW disposal requires a longer time especially in ROK

    Full Text Available Two most significant organizations in the field of financial reporting regulation setters in the world – the Financial Accounting Standard Board (FASB and the International Accounting Standards Board (IASB have recognized that in order international capital markets to function properly, a single set of high-quality international accounting standards designed especially for listed companies around the world must exist. The effort should be especially aimed at spreading the IFRS around the world and the FASB – IASB Convergence. The most significant difference between the US GAAP and IFRSs is in the area of the general approach. The IFRSs are based on basic accounting principles with limited application guidance, US GAAPs are based especially on rules with specific application guidance. The main objective of this work is to assist in the development of an improved common conceptual framework that provides a sound foundation for developing future accounting standards.The structure of the paper is divided into three parts. The theoretical background presents the historical development of the IAS/IFRS and US GAAP convergence efforts in general. The second part of the paper is aimed at the comparative analysis of conceptual frameworks (the IAS/IFRS and US GAAP. At the end, based on the results of the comparative analysis, the basic principles for a common conceptual framework, which should be applicable, are clarified. The paper uses the standard methods of scientific work. Firstly, the method of description is used to describe the development in the area of IAS/IFRS and US GAAP convergence. Then, a comparative analysis is used to discuss the differences in the position a principles of conceptual frameworks the IAS/IFRS and US GAAP. At the end the method of synthesis, deduction and induction is used.

    Full Text Available European-listed companies and many emerging countries have been required to present their consolidated financial statements in compliance with the International Financial Reporting Standards (IFRS since 2005. Having cross-border comparability and transparency with this uniform accounting system is expected to provide higher accounting quality and value relevance. Evaluation of financial performance in terms of value relevance of IFRS is not only vital for existing investors or stakeholders but also for those who want to invest at the international level. Thus, in this study, we examine the value relevance of earnings and book value of equity on share prices through using Ohlson (1995 valuation model. While 2001 to 2004 is conducted as the pre-IFRS period, 2005-2008 is a post-IFRS period to display the change in value relevance in the same number of years. Our sample includes only nonfinancial firms that operate on BIST index. Since financial firms are subject to different regulations, we exclude them from the sample. The results show that the accounting information produced under IFRS is more value relevant. We test the value relevance with both cross-sectional and pooled regression for the periods. In addition, we use panel data analysis (survival analysis to validate the increase in value relevance between the periods. We also test the firm size and earnings announcement effect on value relevance for robustness.

    2017-02-01

    Full Text Available In January 2016, the International Accounting Standards Board (IASB issued IFRS 16 “Leases”, which will replace the current standard IAS 17 “Leases”. IFRS 16, whose application is mandatory for annual periods beginning on or after January 2019, sets out new rules for the recognition and measurement of leases, leading to a change of value for the elements recognized in the financial statements, as well as for the financial indicators calculated based on these. The purpose of this article is to present, based on a comparative analysis of IFRS 16 and IAS 17, the main consequences that the application of IFRS 16 will arise, in respect of the financial statements and the financial indicators determined based on the information provided by these.

    2015-12-01

    Full Text Available This research aims to analyze factors that influence the likelihood of IFRS adoption in developing countries. Research that focuses on the IFRS adoption in developing countries is limited. Developing countries are supposed to get many benefits from the adoption of IFRS as it is a cheap shortcut to improve the quality of financial reporting to attract foreign capital and to finance its development. In addition to macroeconomic factors, this research also examines the influence of institutional factors and the development of local accounting standards. Using the binomial logit regression, the result shows that the regulatory quality of a country positively af-fects the possibility of IFRS adoption in developing countries. It means that the better quality of the regulator in those countries, the higher possibility to fully adopt the IFRS. Furthermore, there is a tendency that the countries will fully adopt the IFRS when they already have local accounting standards that previously referred to international standards. The results imply that the IASB strategy should focus more on cooperation with local regulators or groups of regional cooperation to reach its objective to develop single set of high quality international standard.

    Cement production process has been highly energy and cost intensive. The cement plant requires 8784 h per year of the total operating hours to produce 640,809 tonnes of clinker. To achieve effective and efficient energy management scheme, thermal energy audit analysis was employed on the pyroprocessing unit of the cement plant. Fuel combustion generates the bulk of the thermal energy for the process, amounting to 95.48% (4164.02 kJ/kg cl ) of the total thermal energy input. Thermal efficiency of the unit stands at 41%, below 50-54% achieved in modern plants. The exhaust gases and kiln shell heat energy losses are in significant quantity, amounting to 27.9% and 11.97% of the total heat input respectively. To enhance the energy performance of the unit, heat losses conservation systems are considered. Waste heat recovery steam generator (WHRSG) and Secondary kiln shell were studied. Power and thermal energy savings of 42.88 MWh/year and 5.30 MW can be achieved respectively. Financial benefits for use of the conservation methods are substantial. Environmental benefit of 14.10% reduction in Greenhouse gases (GHG) emissions could be achieved.

    Full Text Available The aim of the paper is to evaluate the degree of social responsibility arising from the statement of comprehensive income prepared according to IAS/IFRS, to demonstrate whether the values obtained from prospects and from the calculation of the indicators are sufficient to analyze the Company's performance from the perspective of social responsibility and sustainable value or not. In order to achieve the objective of harmonization, the European Union adopted the IAS/IFRS developed by the International Accounting Standards Board (IASB. The research is divided into two sections and the approach used is mainly theoretical and qualitative. In the first part, the financial statements to be prepared according to IAS 1 and IAS 7 and, in particular, the so called statement of profit or loss and other comprehensive income for the period are analyzed by underling the function of the same and by presenting some financial performance indicators. Then, the research highlights how these values obtained are not useful to communicate the company's strategy in terms of social responsibility and sustainable value. In the second part the analyses exposes the concept of social balance. According to the social responsibility view the IAS/IFRS financial statements should be accompanied by the social balance. It becomes crucial to complete the set of financial statements stated from IAS 1 with a social balance as well as the same IAS 1 contemplates. For this reason it is possible to say that the connection between IAS/IFRS and social responsibility is weak.

For during that year’s financial reporting cycle, as many as 7,000 listedcompanies in the 25 European Union member states, plus many others in countries such asAustralia, New Zealand, Russia, and South Africa were expected (in the EU, required toproduce annual financial statements in compliance with a single set of international rules—International Financial Reporting Standards (IFRS. Many other business entities, whilenot publicly held and not currently required to comply with IFRS, will also do so, eitherimmediately or over time, in order to conform to what is clearly becoming the newworldwide standard. Since there are about 15,000 SEC-registered companies in the USAthat prepare financial statements in accordance with US GAAP (plus countless nonpubliclyheld companies also reporting under GAAP, the vast majority of the world’s largebusinesses will now be reporting under one or the other of these two comprehensivesystems of accounting and financial reporting rules.Most other national GAAP standards have been reduced in importance or are being phasedout as nations all over the worlds are now embracing IFRS. For example, Canada hasannounced that Canadian GAAP (which was very similar to US GAAP will be eliminatedand replaced by IFRS by 2011. More immediately, China will require listed companies toemploy IFRS. It is quite predictable that only US GAAP will (for the foreseeable futureremain as a competitive force in the accounting standards arena, and even that situation willbe more a formality than a substantive reality, given the formal commitment (andsubstantial progress made to date to “converge” US GAAP and IFRS.

    This paper reports on the Integral Fast Reactor (IFR) which is a generic advanced liquid metal cooled reactor concept being developed at Argonne National Laboratory. There are a number of technical features of the IFR which contribute to its potential as a next-generation reactor. These are associated with large safety margins with regard to off-normal events involving the heat transport system, and the use of metallic fuel which makes possible the utilization of innovative fuel cycle processes. The latter feature permits fuel cycle closure with compact, low-cost reprocessing facilities, collocated with the reactor plant. These primary features are being demonstrated in the facilities at ANL-West, utilizing Experimental Breeder Reactor II and the associated Fuel Cycle Facility (FCF) as an IFR prototype. The demonstration of this IFR prototype includes the design and implementation of the Mass-tracking System (MTG). In this system, data from the operations of the FCF, including weights and batch-process parameters, are collected and maintained by the MTG running on distributed workstations

Based on these assumptions, this desktop study reviewed several documents to determine whether the IFRS adoption has led to increased financial reporting quality in Zimbabwe. The researchers reviewed literature on how the IAS/IFRS and regulations affect the financial reporting quality of listed companies. The factors around IFRS adoption were identified (mandatory, voluntary and convergence and discussed in relation to the financial reporting quality. Evidence from previous studies conducted in line with this same issue shows that there is no conclusive evidence on how IFRS and regulations affect the financial reporting quality. Issues to be addressed in further studies include the importance of financial statements prepared under IFRS framework and the importance of compliance with accounting and auditing requirements

    In the pyroprocessing of spent nuclear fuels, LiCl-KCl waste salt containing radioactive rare earth chlorides are generated. The radioactive rare earth oxides are recovered by co-oxidative precipitation of rare earth elements. The powder phase of rare earth oxide waste must be immobilized to produce a monolithic wasteform suitable for storage and ultimate disposal. The immobilization of these waste developed in this study involves a solid state sintering of the waste with host borosilicate glass and zinc titanate based ceramic matrix (ZIT). And the rare-earth monazite which synthesised by reaction of ammonium di-hydrogen phosphate with the rare earth oxides waste, were immobilized with the borosilicate glass. It is shown that the developed ZIT ceramic wasteform is highly resistant the leaching process, high density and thermal conductivity.

    Full Text Available Strong international integration and globalization affects the contemporary world´s economy which has influence in development of movement of capital, financial markets and decision making of each business entity. Because of increased force to comparability between companies, the idea of one single-setting globally accepted financial reporting standards was started in 1973 in London by International Accounting Standards Committee (IASC as a standards setter of International Accounting Standards (IAS. In the year 2000 the International Organization of Securities Commission (IOSCO recommended to use IFRS for all their members. The paper states about Prague Stock Exchange (PSE as a member of IOSCO, its index PX and companies which create the index PX. The index base is composed of 14 companies which reported their financial statements in accordance with International Financial Reporting Standards (IFRS, earlier IAS. The aim of the paper is to briefly introduce Prague Stock Exchange and index PX and to evaluate the chosen disclosure requirements of companies which create the index. The disclosure requirements, which are assessed are chosen from IAS 1: Presentation of Financial Statements and IFRS 8: Segments reporting. Research of disclosure requirements has been done by gathering the financial statements from years: 2011 and 2012 and assessment of chosen question is based on disclosure requirements of IAS 1 and IFRS 8. Those standards were chosen because of the wide range of companies. The next part of research is to assess the development between the compared years.

    The separation characteristics of surrogate rare-earth fission products in a eutectic (LiCl-KCl) molten salt were investigated. This system is based on the eutectic salt used for the pyroprocessing treatment of used nuclear fuel (UNF). The investigation was performed using an integrated rare-earth separation apparatus comprising a precipitation reactor, a solid detachment device, and a layer separation device. To separate rare-earth fission products, a phosphate precipitation method using both Li3PO4 and K3PO4 as a precipitant was performed. The use of an equivalent phosphate precipitant composed of 0.408 molar ratio-K3PO4 and 0.592 molar ratio-Li3PO4 can preserve the original eutectic ratio, LiCl-0.592 molar ratio (or 45.2 wt%), as well as provide a high separation efficiency of over 99.5% under conditions of 550 °C and Ar sparging when using La, Nd, Ce, and Pr chlorides. The mixture of La, Nd, Ce, and Pr phosphate had a typical monoclinic (or monazite) structure, which has been proposed as a reliable host matrix for the permanent disposal of a high-level waste form. To maximize the reusability of purified eutectic waste salt after rare-earth separation, the successive rare-earth separation process, which uses both phosphate precipitation and an oxygen sparging method, were introduced and tested with eight rare-earth (Y, La, Ce, Pr, Nd, Sm, Eu and Gd) chlorides. In the successive rare-earth separation process, the phosphate reaction was terminated within 1 h at 550 °C, and a 4-8 h oxygen sparging time were required to obtain over a 99% separation efficiency at 700-750 °C. The mixture of rare-earth precipitates separated by the successive rare-earth separation process was found to be phosphate, oxychloride, and oxide. Through the successive rare-earth separation process, the eutectic ratio of purified salt maintained its original value, and impurity content including the residual precipitant of purified salt can be minimized.

  14. IAS/IFRS and financial reporting quality: Lessons from the European experience

    Full Text Available This paper discusses the effects of the adoption of IAS/IFRS in Europe on the quality of financial reporting. In doing so, it adopts the perspective of stock market investors and focuses on value-relevance research. The adoption of IAS/IFRS in Europe is an example of accounting standardization among countries with different institutional frameworks and enforcement rules. This allows investigating whether, and to what extent, accounting regulation per se can affect the quality of financial reporting and leads to convergence in financial reporting. This is a key issue for standard setting purposes as IAS/IFRS have been adopted in very diverse countries all over the world, and many others are likely to adopt them in the near future.

    Full Text Available Abstract: Does IFRS have the impact on earning’s quality and audit fees? The purpose of this research is to provide empirical evidence regarding the impacts of IFRS’s adoption on earning’s quality and audit fee. This research used nonfinancial companies in Indonesia Stock Exchange in 2010-2014 before Asean Economic Community implementation in 2015. The data was collected by employing purposive sampling, which was then analysed by using panel regression method. The result showed that on one hand, the adoption of IFRS did not affect earning’s quality, while on the other hand, it is proven that earning’s quality affected audit fee for companies adopting IFRS. Therefore, companies in Indonesia should update with the progress of the international standard.

  16. Proposed fuel cycle for the Integral Fast Reactor

    Burris, L.; Walters, L.C.

    1985-01-01

    One of the key features of ANL's Integral Fast Reactor (IFR) concept is a close-coupled fuel cycle. The proposed fuel cycle is similar to that demonstrated over the first five to six years of operation of EBR-II, when a fuel cycle facility adjacent to EBR-II was operated to reprocess and refabricate rapidly fuel discharged from the EBR-II. Locating the IFR and its fuel cycle facility on the same site makes the IFR a self-contained system. Because the reactor fuel and the uranium blanket are metals, pyrometallurgical processes (shortned to ''pyroprocesses'') have been chosen. The objectives of the IFR processes for the reactor fuel and blanket materials are to (1) recover fissionable materials in high yield; (2) remove fission products adequately from the reactor fuel, e.g., a decontamination factor of 10 to 100; and (3) upgrade the concentration of plutonium in uranium sufficiently to replenish the fissile-material content of the reactor fuel. After the fuel has been reconstituted, new fuel elements will be fabricated for recycle to the reactor

    Nuclear power accounts for more than 30 percent of power production in Korea. Its significance has annually been increased. Disposal spent fuel containing uranium, transuranic elements, and fission products is unavoidable byproduct of nuclear power production. it is recognized that finding appropriate sites for interim storage of disposal spent fuel is not easy because isolated sites should be required. Pyro-processing technology, Pyro-processing should be operated under high radiation environment in hot-cell structures. Because of this reason, all workers should be unauthorized to access inside the hot-cell areas under any circumstances except for acceptable dose verification and a normal operation should be remotely manipulated. For the reliable normal operation of pyroprocessing, it is noted that an evaluation of the space dose distribution in the hot-cell environments is necessary in advance in order to determine which technologies or instruments can be utilized on or near the process as the Integrated Operation Verification System (IOVS) is measured. Not like the electroreduction and electro-refining hot-cells, the head-end hot-cell equips Camera Radiation Detector (CRD) in which plutonium is securely measured and monitored for the safeguard of the pyro-processing. Results have been obtained using F2 surface tally in order to observe the magnitude of the gamma-ray and neutron flux which pass through the surface of the process cell. Furthermore, T-mesh tally has also been used to obtain the space dose distribution in the headend hot-cell. The hot-cell was divided into 7,668 cells in which each dimension was 1 x 1 x 1m for the T-mesh tally. To determine the position of the CRD and the surveillance camera, divergent approaches were required. Because the purpose of the CRD which contains a gamma-ray detector and a neutron detector is to identify the material composition as the process proceeds, the position in which detectable flux is exposed is required, whereas

    Full Text Available This paper aims to analyse the changes in accounting surplus (loss, equity and assets, and liabilities as a result of accounting policy changes from the Australian Accounting Standards (AAS to the International Financial Reporting Standards (IFRS in Australian local government entities. Using the reconciliation notes disclosed by 117 local government entities, evidence is provided on the effects of IFRS adoption by identifying the key items that of difference between IFRS and AASB. The results show some differences between two sets of accounts prepared under these different accounting standards. While the average surplus (loss of local councils has decreased, their equities, assets and liabilities have increased, with no major significant changes in their overall financial position, except for liabilities. These results indicate the possible consequences of the adoption of IFRS by local government entities in other countries on performance indicators who have or are yet to implement these standards.

    Full Text Available The International Financial Reporting Standards (IFRS was adopted by Ghana in 2007. The study assessed eighteen (18 professional accountants from listed firms on the Ghana Stock Exchange (GSE, to measure the benefits and challenges of IFRS. The study revealed that IFRS improved the access of local companies to international markets. It was also observed that the local firms gained more credibility, transparency, acceptance and consolidation following its adoption. However, most respondents believed that decreasing information cost, competitive leading edge, and integration of accounting Information Technology system were not major benefits as proposed by literature. Nonetheless, some of these local companies after the migration faced challenges like coping with the sophistication of the new standard, lack of qualified personnel, and additional operational cost. Nevertheless, most of the respondents disagreed with the proposition that IFRS had a negative impact on their firms’ balance of retained earnings.

    Full Text Available In this paper we analyse the evolution in the level of convergence of the Romanian accounting regulations with IFRS in the last decade. We focus our study on the accounting topics covered by IAS16, IAS17, IAS 41 and SIC15. We find that in 2005 the regulations exhibit a good level of convergence for property, plant and equipment, a medium level of convergence for lease accounting and divergence for accounting for the agricultural activity. The overall convergence level improved over time for all the topics analysed. These results indicate that the companies with dual reporting may incur lower costs in applying IFRS. Moreover, the national regulations offer the opportunity for a higher level of comparability in Romania of the financial statements prepared under IFRS with those prepared under national regulations. However, we underline that the institutional factors (such as the tax influence over accounting might negatively affect the convergence of practices.

  17. Heterogeneity in earnings quality between different classes of companies after IFRS adoption: evidence from Brazil

    Directory of Open Access Journals (Sweden)

    Roberto Black

    Full Text Available ABSTRACT This paper aims to investigate the existence of heterogeneity in earnings quality between different classes of companies after the adoption of the International Financial Reporting Standards (IFRS. IFRS adoption is generally associated with an increase in the quality of financial statements. However, companies within the same country are likely to have different economic incentives regarding the disclosure of information. Thus, treating companies equally, without considering the related economic incentives, could contaminate earnings quality investigations. The case of Brazil is analyzed, which is a country classified as code-law, in which tax laws determined accounting practice and in which IFRS adoption is mandatory. First, Brazilian companies listed on the São Paulo Stock, Commodities, and Futures Exchange (BM&FBOVESPA were separated into two classes: companies issuing American Depositary Receipts (ADRs before IFRS adoption and companies that did not issue ADRs until the adoption of IFRS. Then, this second class of companies was grouped, using cluster analysis, into two different subclasses according to economic incentives. Based on the groups identified, the quality of accounting earnings is tested for each class of the companies before and after IFRS adoption. This paper uses timely recognition of economic events, value relevance of net income, and earnings management as proxies for the quality of accounting earnings. The results indicate that a particular class of companies began showing conditional conservatism, value relevance of net income, and lower earnings management after IFRS adoption. On the other hand, these results were not found for the two other classes of companies.

    Highlights: •First time ANN implementation toward pyroprocessing safeguards. •Real time monitoring in terms of intelligent materials detection and accountability. •CV simulation via ANN showing a high accuracy of prediction for the unseen situation. •Elimination of trial and error approach to avoid overfitting in learning. -- Abstract: Electrorefiner (ER) is the heart of pyroprocessing technology which contains different fission, rare-earth, and transuranic chloride compositions during the operation. This is still a developing technology that needs to be advanced for the commercial reprocessing design of used nuclear fuel (UNF) in terms of intelligent materials detection and accountability towards safeguards. A novel signal detection, artificial neural network (ANN), has been proposed in this study to apply on massive ER systemic parameters to simulate cyclic voltammetry (CV) graphs for the unseen situation. ANN could be trained to mimic the system by driving the data sets interrelation between variables to provide current and potential simulated data sets with a high accuracy of prediction. For this purpose, over 230,000 experimental data points reported in literature have been explored—0.5–5 wt% of zirconium chloride (ZrCl 4 ) in LiCl-KCl molten salt with different scan rates at 773 K. This study has illustrated a new framework of ANN implementation to eliminate trial and error approach by comparing the average error of one to three hidden layers with different number of neurons. In addition, this framework results in finding a preferable balance between underfitting and overfitting in deep learning. Furthermore, simulated CV graphs were compared with the experimental data and illustrated a reasonable prediction. The results reveal two structures with three hidden layers providing a good prediction with a low average error. The outcomes indicate that ANN has a strong potential in applying toward safeguards for pyroprocessing technology.

  4. IMPLICATIONS OF THE APPLICATION OF IFRS FOR SMES IN ROMANIA ON TAXABLE AND DISTRIBUTABLE PROFIT

    Full Text Available On 9 July 2009, the International Accounting Standards Board (IASB issued the International Financial Reporting Standard for Small and Medium Sized Entities (IFRS for SMEs which aims to provide a financial reporting framework for SMEs falling within its scope. It is a matter for authorities in each jurisdiction to decide which entities are permitted or required to apply IFRS for SMEs. Because of the connection between accounting and taxation certain european countries had a reluctant position related to the application of IFRS for SMEs. Opponents focused on the incompatibility between IFRS for SMEs framework and the principles commonly accepted for tax purposes. As the individual financial statements drown up in compliance with IFRS for SMEs will serve for profit distribution under the 2nd European Directive the question arises weather the profits determined under these accounting rules can be considered as realized for distribution purposes. In order to mitigate the mismatch between accounting and distributable profits, Member States will need to reconsider the circumstances in which gains and losses arising from re-measurement at fair value through profit and loss should be considered as realized. In this scenario, two important questions arise: What are the potential tax effects of the application of IFRS for SMEs? Is the profit determined under IFRS for SMEs available for distribution or some adjustments are necessary? The paper addresses these issues in the context of the Romanian accounting and taxation systems. Romania represents a relevant case study, as it is one of the European countries with a close linkage between financial and tax, where the fiscal profit is dependent on the accounting profit (currently determined under domestic regulations. The methodology consists in a comparative analysis of the recognition and measurement rules between national accounting regulations and IFRS for SMEs in order to identify the differences with

  5. The combined hybrid system: A symbiotic thermal reactor/fast reactor system for power generation and radioactive waste toxicity reduction

    Hollaway, W.R.

    1991-08-01

    If there is to be a next generation of nuclear power in the United States, then the four fundamental obstacles confronting nuclear power technology must be overcome: safety, cost, waste management, and proliferation resistance. The Combined Hybrid System (CHS) is proposed as a possible solution to the problems preventing a vigorous resurgence of nuclear power. The CHS combines Thermal Reactors (for operability, safety, and cost) and Integral Fast Reactors (for waste treatment and actinide burning) in a symbiotic large scale system. The CHS addresses the safety and cost issues through the use of advanced reactor designs, the waste management issue through the use of actinide burning, and the proliferation resistance issue through the use of an integral fuel cycle with co-located components. There are nine major components in the Combined Hybrid System linked by nineteen nuclear material mass flow streams. A computer code, CHASM, is used to analyze the mass flow rates CHS, and the reactor support ratio (the ratio of thermal/fast reactors), IFR of the system. The primary advantages of the CHS are its essentially actinide-free high-level radioactive waste, plus improved reactor safety, uranium utilization, and widening of the option base. The primary disadvantages of the CHS are the large capacity of IFRs required (approximately one MW e IFR capacity for every three MW e Thermal Reactor) and the novel radioactive waste streams produced by the CHS. The capability of the IFR to burn pure transuranic fuel, a primary assumption of this study, has yet to be proven. The Combined Hybrid System represents an attractive option for future nuclear power development; that disposal of the essentially actinide-free radioactive waste produced by the CHS provides an excellent alternative to the disposal of intact actinide-bearing Light Water Reactor spent fuel (reducing the toxicity based lifetime of the waste from roughly 360,000 years to about 510 years)

Although the IFRS for SMEs was not intended for a specific user group,the majority of the respondents to the Exposure Draft on IFRS for SMEs were from Europe and other developed countries while only limited respondents from Africa and developing countries were involved.  This study considered the relevance of the contents of the IFRS for SMEs in the South African environment based on user requirements. Since SMEs do not necessarily have functional accounting departments and because they rely on external accountants to compile financial statements, we included accounting practitioners and trainee accountants from the SME sector in our survey. As a result we classified the contents of the IFRS for SMEs, from a South African perspective, into different levels of importance or relevance.

    The deployment of nuclear energy systems (NESs) is expanding around the world. Nations are investing in NESs as a means to establish energy independence, grow national economies, and address climate change. Transitioning to the advanced nuclear fuel cycle can meet growing energy demands and ensure resource sustainability. However, nuclear facilities in all phases of the advanced fuel cycle must be ‘safeguardable,’ where safety, safeguards, and security are integrated into a practical design strategy. To this end, the High Reliability Safeguards (HRS) approach is a continually developing safeguardability methodology that applies intrinsic design features and employs a risk-informed approach for systems assessment that is safeguards-motivated. Currently, a commercial pyroprocessing facility is used as the example system. This paper presents a modeling study that investigates the neutron flux associated with processed materials. The intent of these studies is to determine if the neutron flux will affect facility design, and subsequently, safeguardability. The results presented in this paper are for the head-end subsystems in a pyroprocessing facility. The collective results from these studies will then be used to further develop the HRS methodology.

    Full Text Available Development of accounting theory is a way of theory, practice and research. Three aspects of the accounting development is an integrated whole, which would form a logical reasoning embodied in engineering financial reporting to become a Conceptual Framework. In practical terms, the adoption of IFRS is not an option for Indonesia, but must, in the hope, foreign investment will continue to enter or even increased and we are not isolated in the international arena. Nobes ( 2010 in his book states that, the International Accounting Standards have an important role in developing countries. Adoption of IFRS is the cheapest way for these countries than setting its own standards.

    2015-08-01

    Full Text Available Purpose – The degree of corruption, among other things, indicates the non -implementation of laws, weak enforcement of legal sanctions and the existence of non-transparent economic transactions. Therefore, the expected change in reliability (faithful-representation resulting from the adoption of IAS/IFRS, does not depend solely on the adoption of IAS/IFRS but is also influenced by the degree of corruption in each country. The purpose of this paper is to examine whether the above statement is true. Design/methodology/approach – The data were taken from DataStream database and the sample period consists of listed companies of fifteen European countries that adopted IAS/IFRS mandatorily. The time horizon is 10 years, from 2000 until 2009. The period between 2000 and 2004 is defined as the period before the adoption, while the period between 2005 and 2009 is defined as the period after the adoption. The reliability/faithful representation of financial statements - as defined by the Conceptual Framework - is detected through regression analysis. Findings – The findings advocate that the adoption of IFRS/IAS seems to be not enough. It appears that the level of reliability of financial statements in every country does not depend solely on the adoption of IAS/IFRS but is also influenced by the degree of corruption in each country. Research limitations/implications – The models that are used for the measurement of reliability have as an independent variable the short-term accruals. Given that, the models fail to take into consideration accounting treatments that concern non-current assets/liabilities. Originality/value – The findings that are identified for counties with a high degree of corruption indicate a statistically significant reduction in reliability after the adoption of IAS/IFRS. These findings constitute a useful tool for the IASB and the European Commission as well as for the users of financial statements.

    Full Text Available This study aims to analyse the process of harmonization of national accounting standards of the Republic of Moldova to the international standards. It highlights the main advantages, disadvantages, risks and opportunities regarding the implementation of the new standards. A major step for the Republic of Moldova was the implementation of IFRS, which has become mandatory for all public interest entities from 1 January 2012 and the adoption of new NAS in accordance with EU Directives and IFRS for small and medium-sized entities, for which the transition to IFRS was difficult due to high costs involved. The new NAS came into force on 1 January 2014 as a recommendation, but starting with 1st January 2015 it will be mandatory for all entities. The paper includes a practical analysis of the impact of transition to IFRS on the financial results of a public interest entity- Moldova Agroindbank, which is the largest commercial bank, with the highest market share in the banking sector of the Republic of Moldova. A result of the analysis of primary and secondary indicators calculated on the base of the financial statements prepared by commercial bank at 31.12.11, we found that the transition to IFRS has resulted in the growth of all financial indicators.

    Input nuclear material accountancy is crucial for a pyroprocessing facility safeguards. Until a direct Pu measurement technique is established, an indirect method based on code calculations with burnup measurement and neutron counting for 244 Cm could be a practical option. Burnup can be determined by destructive analysis (DA) for final dispositive accuracy or by nondestructive assay (NDA) for near-real time accountancy. In the present study, an underwater burnup measurement system based on gamma-ray spectroscopy with the CZT detector was developed and tested on a spent fuel assembly. Burnup was determined according to the 134 Cs/ 137 Cs activity ratio with efficiency correction by Geant4 Monte Carlo simulations. The activity ratio as a function of burnup was obtained by ORIGEN calculations. The measured burnup error was 8.6%, which was within the measurement uncertainty. It is expected that the underwater burnup measurement system could fulfill an important role as a means of near-real time accountancy at a future pyroprocessing facility. (authors)

    Directory of Open Access Journals (Sweden)

    Musa Inuwa Fodio

    2015-06-01

    Full Text Available Audit timeliness is an important ingredient of quality financial reporting. Stale information might only benefit little to stakeholders in their decision making process. With the recent adoption of the International Financial Reporting Standards in Nigeria, the work of the auditor has seemingly become complicated. The question then emerges, if such adoption affects the timeliness of audit reports. This study empirically investigates the impact of IFRS adoption and other associated explanatory variables on audit timeliness in Nigerian deposit money banks for the period 2010 to 2013. Panel regression analysis reveals a positive significant impact of IFRS adoption on audit timeliness. Results also indicate that firm age, firm size and auditor firm type are significant predictors of audit timeliness in Nigeria deposit money banks. The study recommends that auditor firms should make stringent efforts to acclimatize with the complexities of the IFRS transition process so as to reduce audit report delays. Also reporting agencies should come up with regulations, deadlines and benchmarks for issuance of independent audit reports.

    Full Text Available The new EU-Accounting Directive of 26 June 2013 (DIRECTIVE 2013/34/EU has the intention to harmonize the accounting and financial reporting of enterprises in the European Union. “Think small first” is the central principle in the new EU-Accounting Directive and the new regulations have to be adopted in the laws of European member states by 20 July 2015. The International Financial Reporting Standard for Small and Medium-sized Entities (IFRS for SMEs was published in 2009 by the International Accounting Standards Board (IASB. The IASB intended to create simplified international financial reporting standards for the special needs of smaller and medium-sized enterprise. The IASB completed in May 2015 a comprehensive review of the IFRS for SMEs and made amendments to the Standard. The revised version of the IFRS for SMEs will be issued in the last quarter of 2015. The aim of the paper is to analyze the compatibility of the IFRS for SMEs and the new EU- Accounting Directive and the problems in connection with the harmonization of the European accounting legislation especially in Germany. Based on the results of the research most of the former incompatibilities could be removed, but the remaining complexity of the IFRS for SMEs and the lack of an option for the member states to adopt the IFRS for SMEs as an accounting and reporting standard besides or instead their local accounting principles will prevent the wide use of the IFRS for SMEs in Germany and in other member states of the European Union.

    Full Text Available Small and medium sized companies have an important position in the economy, mainly in the area of employment. SMEs are crucial to most developed and developing economies. SMEs are a heterogeneous group, possessing different size, sector, or location. Their activities on the international markets are limited by a great deal of obstacles in comparison to large enterprises. Different national financial reporting and tax systems can be considered as the most important obstacles (European Commission, 2003. The International Accounting Standards Board (IASB published an International Financial Reporting Standard (IFRS designed for use by small and medium-sized entities on July, the 9th 2009. The IFRS for SME is designed to meet the financial reporting needs of entities that (a do not have public accountability and (b publish general purpose financial statements for external users. The aim of the paper is to evaluate the current approach to the IFRS for SME adoption and implementation over the world, and to analyze the problems connected with harmonization of financial reporting legislation used by SMEs all over the world. In the paper are identified common characteristic of countries which have already the IFRS for SME adopted. The statistical methods were used for comparison of countries which have already the IFRS for SMEs adopted with those which have not adopted it yet. The level of economic development of the particular country and other characteristics were used for comparison.

    This study reviews new pension accounting with K-IFRS and provides empirical changes in liability for retirement allowances with adoption of K-IFRS. It will help to understand the effect of pension accounting on individual firm's financial report and the importance of public announcement of actuarial assumptions. Firms that adopted K-IFRS had various changes in retirement liability compared to the previous financial report not based on K-IFRS. Their actuarial assumptions for pension accounting should be announced, but only few of them were published. Data analysis shows that the small differences of the actuarial assumption may result in a big change of retirement related liability. Firms within IT industry also have similar behaviors, which means that additional financial regulations for pension accounting are recommended.

    Levy, Salomon

    2006-01-01

    A specific plan consisting of six different steps is proposed to accelerate and improve the long-term management of U.S. Light Water Reactor (LWR) spent nuclear fuel. The first step is to construct additional, centralized, engineered (dry cask) spent fuel facilities to have a backup solution to Yucca Mountain (YM) delays or lack of capacity. The second step is to restart the development of the Integral Fast Reactor (IFR), in a burner mode, because of its inherent safety characteristics and its extensive past development in contrast to Acceleration Driven Systems (ADS). The IFR and an improved non-proliferation version of its pyro-processing technology can burn the plutonium (Pu) and minor actinides (MA) obtained by reprocessing LWR spent fuel. The remaining IFR and LWR fission products will be treated for storage at YM. The radiotoxicity of that high level waste (HLW) will fall below that of natural uranium in less than one thousand years. Due to anticipated increased capital, maintenance, and research costs for IFR, the third step is to reduce the required number of IFRs and their potential delays by implementing multiple recycles of Pu and Neptunium (Np) MA in LWR. That strategy is to use an advanced separation process, UREX+, and the MIX Pu option where the role and degradation of Pu is limited by uranium enrichment. UREX+ will decrease proliferation risks by avoiding Pu separation while the MIX fuel will lead to an equilibrium fuel recycle mode in LWR which will reduce U. S. Pu inventory and deliver much smaller volumes of less radioactive HLW to YM. In both steps two and three, Research and Development (R and D) is to emphasize the demonstration of multiple fuel reprocessing and fabrication, while improving HLW treatment, increasing proliferation resistance, and reducing losses of fissile material. The fourth step is to license and construct YM because it is needed for the disposal of defense wastes and the HLW to be generated under the proposed plan. The

Within this context, the need of a harmonized and well oriented accounting system has become imperative. The adoption of a set of international accounting standards in Europe is intended to provide uniform and high quality financial information on the financial markets which would consolidate the global market efficiency, reducing the cost of capital accessing for European companies. There are numerous opinions according to which the IFRS adoption could be an element of abolishing the discrepancies between the accounting systems, offering at the same time a high level of transparency of the financial information. Our objective is to analyze the opportunity of implementing the IAS/IFRS referential by the Romanian companies, as well as their instant reaction within this context.

    The Instrumented Flux Return (IFR)[1] is one of the five subdetectors of the BaBar[2] experiment on the PEP II accelerator at SLAC. The IFR consists of 774 Resistive Plate Chamber (RPC) detectors, covering an area of about 2,000 m 2 and equipped with 3,000 Front-end Electronic Cards (FEC) reading about 50,000 channels (readout strips). The first aim of a B-factory experiment is to run continuously without any interruption and then the Detector Control system plays a very important role in order to reduce the dead-time due to the hardware problems. The I.N.F.N. group of Naples has designed and built the IFR Online Detector Control System (IODC)[3] in order to control and monitor the operation of this large number of detectors and of all the IFR subsystems: High Voltage, Low Voltage, Gas system, Trigger and DAQ crates. The IODC consists of 8 custom DAQ stations, placed around the detector and one central DAQ station based on VME technology and placed in electronic house. The IODC use VxWorks and EPICS to implement slow control data flow of about 2500 hardware channels and to develop part of the readout module consisting in about 3500 records. EPICS is interfaced with the BaBar Run Control through the Component Proxy and with the BaBar database (Objectivity) through the Archiver and KeyLookup processes

    The Integral Fast Reactor (IFR) is a generic advanced liquid metal cooled reactor concept being developed at Argonne National Laboratory (ANL). There are a number of technical features of the IFR which contribute to its potential as a next-generation reactor. These are associated with large safety margins with regard to off-normal events involving the heat transport system, and the use of metallic fuel which makes possible the utilization of innovative fuel cycle processes. The latter feature permits fuel cycle closure the compact, low-cost reprocessing facilities, collocated with the reactor plant. These primary features are being demonstrated in the facilities at ANL-West, utilizing Experimental Breeder Reactor 2 and the associated Fuel Cycle Facility (FCF) as an IFR prototype. The demonstration of this IFR prototype includes the design and implementation of the Mass-Tracking System (MTG). In this system, data from the operations of the FCF, including weights and batch-process parameters, are collected and maintained by the MTG running on distributed workstations. The components of the MTG System include: (1) an Oracle database manager with a Fortran interface, (2) a set of MTG ''Tasks'' which collect, manipulate and report data, (3) a set of MTG ''Terminal Sessions'' which provide some interactive control of the Tasks, and (4) a set of servers which manage the Tasks and which provide the communications link between the MTG System and Operator Control Stations, which control process equipment and monitoring devices within the FCF

    Full Text Available Starting from the year 2002, the Turkish national regulatory agency hasundertaken an extensive role in the convergence efforts towards IFRS. In order tosupport the transition, the Turkish Capital Markets Board (TCMB implementedseveralversionsof IFRS,regulatory practices and compliance requirements- allover the course of 15 years. The first effort undertaken in the road to IFRStransition was the issuance of Series XI, No: 25 by the TCMB. However, SeriesXI, No: 25 was not fully compatible with the international standard set and SeriesXI, No: 27 was put into effect in order to allow the companies to refer to theoriginal IFRS when necessary. This has created three groups of reportingcompanies; Series XI, no: 25 users, IAS/IFRS users and mixed usersof both sets.Nobes (2006 states that there is a risk that the process of translation will changeor lose meaning from the original version of the standard and as these variousIFRS are given legal status in various countries, this approach can potentially leadto application differences between jurisdictions. In line with this argument, theaim of the current study is to discuss impact of these differences on financialreport comparability and analysis in Turkey.

    Full Text Available This study examines whether there are differences in accounting of goodwill among IFRS, SKK (Albanian Accounting Standards which it is an adoption of IFRS and Albanian tax regulations. The study first presents general theory of intangible assets. This is followed by an elaborate explanation of goodwill which includes a deeper discussion about estimation and valuation and accounting treatment of goodwill. The accounting treatment of goodwill regarding to IFRS and local regulations is analyzed by a real case of purchased goodwill of Albtelecom Sh.A, a telecommunication company which provides fix telephony and internet service. The results of the case study indicate differences between IFRS and Albanian tax legislation in accounting treatment of goodwill, while between IFRS 3 and SKK 9 there is not any difference. According to both standards, goodwill is recognized by purchase method and it is subject to annual impairment test. However, instruction "On Income Tax" requires that, intangible assets such as purchased goodwill, amortized at a rate to allow for the fiscal effect of 15% which is applied on historical costs which may be added the costs of upgrading and renewal of the assets.

  20. A Country Specific Approach To IFRS Accounting Policy Choice In The European, Australian And Turkish Context

    Full Text Available IAS 8 defines the concept of accounting policy as "the specific principles, bases, conventions, rules and practices applied by an entity in preparing and presenting financial statements". Within the framework of this concept, this research that is derived from International Financial Reporting Standards (IFRS contributes to the accounting literature by focusing on the alternative accounting policies' debate related to presentation and recognition issues in the European, Australian and Turkish context and concludes that there is an influence of local accounting policies over IFRS practice in Turkey and this influence still exists in Europe and Australia. This shows that as long as diversity in accounting policies of IFRS is present, entities are expected to be inclined to select their local accounting policies by leading to comparability of financial statements within the country rather than between countries in the IFRS context.

    We propose to observe a large sample of radio sources from the ATLAS (Australia Telescope Large Area Survey) source catalogue with the LBA, to determine their compactness. The sample consists of 36 sources with no counterpart in the co-located SWIRE survey (3.6 um to 160 um), carried out with the Spitzer Space Telescope. This rare class of sources, dubber Infrared-Faint Radio Sources (IFRS), is inconsistent with current galaxy evolution models. VLBI observations are an essential way to obtain further clues on what these objects are and why they are hidden from infrared observations. We will measure the flux densities on long baselines to determine their compactness. Only five IFRS have been previously targeted with VLBI observations (resulting in two detections). We propose using single baseline (Parkes-ATCA) eVLBI observations with the LBA at 1 Gbps to maximise sensitivity. With the observations proposed here we will increase the number of VLBI-observed IFRS from 5 to 36, allowing us to draw statistical conclusions about this intriguing new class of objects.

    Full Text Available The apparent expansion of IFRS internationally promoted literature interests in analyzing their impact on the earnings quality. In these associations, research indicated setbacks in empirical findings with these dilemmas more pronounced in studies of companies from developing countries. Therefore, in this study, we investigated, from the economic and institutional perspectives, if the IFRS affected the persistence and the value relevance of financial results of companies in GLENIF countries. To test these predictions, the survey included 563 companies from Argentina, Brazil, Chile, Colombia, Mexico and Peru from 2003 to 2014. With the application of models of Easton and Harris (1991; Ohlson (1995, Sloan (1996; Burgstahler and Dichev (1997 and Pincus, Venkatachalam and Rajgopal (2007 employed the regression panel data. The results showed a partial acceptance of the hypothesis. The accounting data were more relevant after the implementation of IFRS, while only Argentina, Colombia and Mexico showed the most persistent financial results. In comments on the preliminary adoption of IFRS, the financial results of companies in the countries were more persistent in adopting for a longer period these standards, as opposed to the value relevance, there were no significant differences after IFRS. In summary, this study found that the IFRS alone are not institutional factors to fully improve the quality of accounting results in developing countries.

    Full Text Available Purpose: This study aims to assess the impact of adopting IFRS standard on the equity cost of Brazilian open capital companies in the period of 2004-2013. Originality/gap/relevance/implications: The adoption of International Financial Reporting Standards aims to increase the quality of accounting information. Studies performed in Europe suggest that, after the adoption of the IFRS standard, there was a reduction in the equity cost of companies due to the reduction of information asymmetry and risk. Key methodological aspects: The equity cost was calculated using the capital asset pricing model (CAPM adapted to the Brazilian case. The empirical strategy was the difference analysis in differences, comparing the results of companies that voluntarily adopted the IFRS with companies that adopted IFRS after the mandatory adoption period. Summary of key results: The results indicate that the adoption of the IFRS standard does not contribute to reduce the equity cost in Brazil. Key considerations/conclusions: Suggesting that the process of adopting the international accounting standard may take more time to impact the equity cost of Brazilian open capital companies, since the impact of IFRS is not related only with the adoption, but also with its use by companies and users. Objetivo: Este trabalho se propõe a avaliar o impacto da adoção do padrão IFRS sobre o custo de capital próprio das empresas de capital aberto no Brasil.

    Full Text Available Abstract. The purpose of this study is to provide empirical evidence about the effect of IFRS adoption and investor protection on earnings persistence. Based on prior studies, there are some problems that existed in the accounting practices in emerging markets such as less an accountant who have good qualifications, incomplete accounting information or inaccuracy of time in preparing financial statements, the lack of accounting data that are used for internal management incentives, the lack of legislation, auditing standards and procedure of accounting standards and this issues will can affect the quality of accounting information that reported in financial statements. So this view initiate to investigate extensively about the effect of institutional factors on earnigs persistence.This study uses panel data with 12.903 firm-year observations in emerging markets evidence from 2011 to 2013. To measure IFRS adoption uses score based on three distinctions of the type from IFRS adoption in respective countries. And then for dependent variable in this study is earnings persistence. While for the investor protection uses strength of investor protection index proxy from World Bank.The findings imply that in the context of emerging markets, IFRS adoption is not associated with future earnings persistence. While a stronger investor protection in the country significantly correlated with greater earnings persistence.

  10. Waste Minimization Study on Pyrochemical Reprocessing Processes

    2006-01-01

    Ideally a new pyro-process should not generate more waste, and should be at least as safe and cost effective as the hydrometallurgical processes currently implemented at industrial scale. This paper describes the thought process, the methodology and some results obtained by process integration studies to devise potential pyro-processes and to assess their capability of achieving this challenging objective. As example the assessment of a process based on salt/metal reductive extraction, designed for the reprocessing of Generation IV carbide spent fuels, is developed. Salt/metal reductive extraction uses the capability of some metals, aluminum in this case, to selectively reduce actinide fluorides previously dissolved in a fluoride salt bath. The reduced actinides enter the metal phase from which they are subsequently recovered; the fission products remain in the salt phase. In fact, the process is not so simple, as it requires upstream and downstream subsidiary steps. All these process steps generate secondary waste flows representing sources of actinide leakage and/or FP discharge. In aqueous processes the main solvent (nitric acid solution) has a low boiling point and evaporate easily or can be removed by distillation, thereby leaving limited flow containing the dissolved substance behind to be incorporated in a confinement matrix. From the point of view of waste generation, one main handicap of molten salt processes, is that the saline phase (fluoride in our case) used as solvent is of same nature than the solutes (radionuclides fluorides) and has a quite high boiling point. So it is not so easy, than it is with aqueous solutions, to separate solvent and solutes in order to confine only radioactive material and limit the final waste flows. Starting from the initial block diagram devised two years ago, the paper shows how process integration studies were able to propose process fittings which lead to a reduction of the waste variety and flows leading at an 'ideal

    Full Text Available The article investigates the nature of the accounting policies as a set of principles, approaches, methods, forms and procedures used for the purpose of accounting and reporting. Accounting policies are an important step in the organization of accounting, where the subject is the management of a company and the object is the system of accounting and reporting, and are designed to provide users with information needed to make effective managerial decisions. For resident companies applying IFRS for financial reporting, we suggest the structure for a document on accounting policies, which allows to take into account all the key points of accounting policy and, if necessary, can be expanded. In addition, we define the main factors that influence the development of accounting policies in the framework of IFRS.

    2012-01-01

    Full Text Available The process of integration and globalization is closely related to the need for harmonization of accounting at international level. In this connection International Financial Reporting Standards (IFRS have been developed, which are primarily designed for companies whose securities are traded on regulated markets of the European Union. However, as the importance of small and medium-sized entities has been recently on the increase, the International Accounting Standards Board (IASB also issued after five years of effort in July 2009 the International Financial Reporting Standard for Small and Medium-sized Entities (IFRS for SMEs. At present, there is no legislation for the application of this standard in the Czech Republic or any other state of the European Union. Each jurisdiction must determine whether to adopt IFRS for SMEs, to what extent and for which entities the standard is mandatory and for which it is not. Already in previous years the European Commission analyzed data from surveys on this new standard and discussed its advantages and disadvantages. To date, however, it has not taken a single decision on whether to adopt and incorporate the standard into the European accounting legislation. The question also remains what attitude towards IFRS for SMEs companies operating in the Czech Republic will take. That is why this paper analyzes the opinions of some Czech companies belonging to the group of SMEs on the potential adoption of this standard.

  16. Developing a Signature Based Safeguards Approach for the Electrorefiner and Salt Cleanup Unit Operations in Pyroprocessing Facilities

    2016-01-27

    Traditional nuclear materials accounting does not work well for safeguards when applied to pyroprocessing. Alternate methods such as Signature Based Safeguards (SBS) are being investigated. The goal of SBS is real-time/near-real-time detection of anomalous events in the pyroprocessing facility as they could indicate loss of special nuclear material. In high-throughput reprocessing facilities, metric tons of separated material are processed that must be accounted for. Even with very low uncertainties of accountancy measurements (<0.1%) the uncertainty of the material balances is still greater than the desired level. Novel contributions of this work are as follows: (1) significant enhancement of SBS development for the salt cleanup process by creating a new gas sparging process model, selecting sensors to monitor normal operation, identifying safeguards-significant off-normal scenarios, and simulating those off-normal events and generating sensor output; (2) further enhancement of SBS development for the electrorefiner by simulating off-normal events caused by changes in salt concentration and identifying which conditions lead to Pu and Cm not tracking throughout the rest of the system; and (3) new contribution in applying statistical techniques to analyze the signatures gained from these two models to help draw real-time conclusions on anomalous events.

    Full text of publication follows. Electrochemical treatment of spent oxide fuels has been intensively studied in KAERI to reduce the volume, heat load and radiotoxicity of high-level wastes. It consists of an electrolytic reduction process to convert the oxide fuel into a metallic form and an electro-refining process to separate TRU elements from the electro-reduced metal ingot. Two types of waste salts are expected to generate from the electrochemical pyro-processes, that is, LiCl salt from the reduction process and LiCl+KCl eutectic salt form the refining process. The R and D strategy of the waste salt management in KAERI can be categorized into two parts: 1) enhancement of safety by the stabilisation/solidification of waste salt that is to be finally disposed of and 2) reduction of the waste generation by the regeneration/recycle of the spent salt after removal of radionuclides in it. A sol-gel technique and a zeolite occlusion technique are under development to stabilize the waste salt. The LiCl salt is stabilised by a low-temperature sol-gel process and then the gel product is solidified into a ceramic-like waste form with an addition of glass frit. Another method uses Zeolite-4A to occlude the LiCl salt into its cage and adsorption site to immobilize the radionuclides. The product, salt-occluded zeolite, is fabricated into another type of a ceramic waste form. For the regeneration and recycle of the spent salt, the radionuclides in the salt are removed by a zeolite process for the LiCl salt and by an oxidation/distillation process for the eutectic salt. The target nuclides to be removed in each process are Cs/Sr and rare earth (RE) elements, respectively. In the oxidation/ distillation process, the rare earth chloride nuclides are oxidised by an oxygen sparging method, and the products are precipitated in the form of oxide or oxychloride REs. After separation of the RE elements from the precipitates by distillation, the refined spent salt with a low content

Partial harmonization of recording and financial reporting of business combination in Europe and in the USA was the main objective of IFRS 3 (2004. IFRS 3 (2004 is based on SFAS 141 (2001. SFAS 141 (2001 was developed in 2001 and replaced APB (Accounting Principles Board Opinion No. 16 Business Combinations and SFAS 38. There is the pooling interest method forbidden and only the purchase method is allowed for all kinds of business combinations. Based on the comparison of both methodical approaches to business combinations are demonstrated reasons for refusing of pooling interest method. The second phase is aimed at purchase method application and new methodical approaches to business combination recording and it is the objective of the conclusion of this paper.

    This paper focuses on the importance of accounting harmonisation in foreign activities at country level. The adoption of International Financial Reporting Standards (IFRS) is considered to reduce information costs among countries and, therefore, encourage international trade in goods and investment. The results provide evidence that benefits exist in terms of trade in goods and foreign direct investments (FDI) when IFRS are adopted.

    Full Text Available In the context of current interconnected capital markets, all the investors, regardless their country of origin would be provided with the improvement of the quality and comparability of financial information due to the high quality of some common standards of financial reporting. In order to achieve this, the two bodies, the FASB and the IASB, are working together to reduce the differences between the IFRS and the US GAAP. However, there are some problems observed by the US SIF managers, which fall under their area of work. They are divided in three groups: The lack of essential information expected by the American investors. For example, the IFRS does not impose the presentation of the investments made by an investment company; Different assessment bases for the financial actives and debts in the IFRS, which influences the main indicators for the investors; Presenting relevant information regarding the risks taken by investment funds and the analysis of proneness to these risks.

The United States has made substantial progress in achieving ALMR program objectives. After a competitive period, a decision was made in 1988 to select the General Electric ALMR concept known as PRISM (Power Reactor Innovative Small Module) for advanced conceptual design. Significant accomplishments have been achieved in design, licensing and economics, even though the original schedule has been stretched due to funding limitations. The Department of Energy's role is to advance the concept to a sufficient level that would enable private sector and/or international interests to further development and construction of a full size prototype plant. A key strategy within the U.S. ALMR program is to evaluate the potential of metal fuel based on the Integral Fast Reactor (IFR) concept developed at ANL. The technology supports practical actinide recycling. The metal fuel cycle is designed to recycle and burn its own minor actinides, and has the potential to be a very effective utilizer of the Pu and minor actinides generated in the LWRs. The entire ALMR system can thus extend uranium resources by a hundred-fold, making nuclear essentially the same as a renewable energy source. The scientific principles involved in the IFR concept have been shown to be soundly-based, surpassing expectations in several instances. The IFR Program is developing a comprehensive technology and is now preparing the definitive technology demonstration of the economic feasibility of the concept. The development effort includes large scale irradiation of the U-Pu-Zr ternary alloy metallic fuel to provide the basis for commercial fabrication specification; optimization of the flowsheet for the IFR pyroprocessing method for efficient fuel recycle and waste management; design and testing of plant-scale pyroprocessing equipment; characterization of

    Full Text Available Since the external trading activity accounts for an important source of national economy growth, being the developed states economy driver, the authors considered that at the level of the entities carrying out external trading activities, the own bookkeeping must be organized taking into account the specific of the activity developed. In this context, the authors began the preparation of the study starting from the idea that this category of companies must provide accounting information as qualitative as possible that can be easily comparable at the international level and hereby increase the international commercial exchanges. Meeting this challenge of increasing the external trading activities involves the adoption of specific measures, in line with the real state of performance and with the current needs of the companies from the national economy. A relevant measure is considered to be IFRS (International Financial Reporting Standards implementation for this category of companies in order to increase the quality of the accounting information provided and implicitly of some new businesses with the abroad. In order to test the opinion related to IFRS implementation on the companies carrying out external trading activities, the authors prepared a study based on a questionnaire that targeted Romanian companies carrying out external trading activities, of different dimensions. The purpose of this questionnaire was to draw up conclusions related to the content, need and the information usability of the data reported through financial positions by the companies carrying out external trading activities. The questions addressed by the authors, in this respect, have predefined answers, meant to obtain the opinion of the Romanian companies related to the possible IFRS implementation, irrespective of size, of the impact forecasted of IFRS implementation process on the companies’ activity, as well as the importance granted to the auditing of collection

  14. Knock-Down of the IFR1 Protein Perturbs the Homeostasis of Reactive Electrophile Species and Boosts Photosynthetic Hydrogen Production in Chlamydomonas reinhardtii.

    The protein superfamily of short-chain dehydrogenases/reductases (SDR), including members of the atypical type (aSDR), covers a huge range of catalyzed reactions and in vivo substrates. This superfamily also comprises isoflavone reductase-like (IRL) proteins, which are aSDRs highly homologous to isoflavone reductases from leguminous plants. The molecular function of IRLs in non-leguminous plants and green microalgae has not been identified as yet, but several lines of evidence point at their implication in reactive oxygen species homeostasis. The Chlamydomonas reinhardtii IRL protein IFR1 was identified in a previous study, analyzing the transcriptomic changes occurring during the acclimation to sulfur deprivation and anaerobiosis, a condition that triggers photobiological hydrogen production in this microalgae. Accumulation of the cytosolic IFR1 protein is induced by sulfur limitation as well as by the exposure of C. reinhardtii cells to reactive electrophile species (RES) such as reactive carbonyls. The latter has not been described for IRL proteins before. Over-accumulation of IFR1 in the singlet oxygen response 1 ( sor1 ) mutant together with the presence of an electrophile response element, known to be required for SOR1-dependent gene activation as a response to RES, in the promoter of IFR1 , indicate that IFR1 expression is controlled by the SOR1-dependent pathway. An implication of IFR1 into RES homeostasis, is further implied by a knock-down of IFR1 , which results in a diminished tolerance toward RES. Intriguingly, IFR1 knock-down has a positive effect on photosystem II (PSII) stability under sulfur-deprived conditions used to trigger photobiological hydrogen production, by reducing PSII-dependent oxygen evolution, in C. reinhardtii . Reduced PSII photoinhibition in IFR1 knock-down strains prolongs the hydrogen production phase resulting in an almost doubled final hydrogen yield compared to the parental strain. Finally, IFR1 knock-down could be

    Full Text Available O objetivo desse estudo é verificar o impacto do processo de convergência às IFRS no grau de intangibilidade de empresas listadas na BM&FBOVESPA. O universo da pesquisa é composto pelas companhias brasileiras listadas na BM&FBovespa. A amostra final compreendeu 904 observações no período de 2006 a 2012. Foi testada, por meio de Regressão de Dados em Painel, a relação entre o grau de intangibilidade das empresas e as variáveis total do ativo e patrimônio líquido, ROA, ROE, preço das ações e ativo intangível, além de duas dummies para capturar os efeitos dos períodos pré e pós-IFRS. Os resultados apontam uma influência negativa da adoção das IFRS sobre o grau de intangibilidade (GI das entidades analisadas, embora não significativa. A redução no GI indica que o patrimônio líquido contábil está mais próximo do valor de mercado das empresas analisadas após a adoção das IFRS. Conclui-se, assim, que há indícios de uma tendência de melhoria da qualidade da informação contábil com o processo de convergência às IFRS.

    Full Text Available This study evaluates the impact of IFRS adoption, fair value information of property, plant, and equipment (PPE, and disclosure of appraiser services into a firm's information asymmetry. Information asymmetry is the primary reason for the existence of accounting. Accounting could be a mechanism to enable communication of useful information from insiders to outsiders. IFRS adoption and better disclosure are important factors that avoid exploitation by informed bodies, and protect uninformed investors. Using Indonesian data, this study analyzes two year before and after 2011, an implementation year. This research gives evidence that IFRS adoption is able to decrease information asymmetry. Disclosure of appraiser services is also able to decrease information asymmetry, however, fair value information of PPE is not an important determinant of information asymmetry. Other results present that share prices, share turnover, and firm size can affect information asymmetry. By knowing the factors affecting information asymmetry, information asymmetry problem could be minimized. This study concludes that IFRS implementation and disclosure of appraiser services affect information asymmetry.

    Full Text Available Objective – This article aims to measure the impacts of the final phase of mandatory convergence to IFRS on net income, in equity and total assets of Brazilian publics companies. Design/methodology/approach – It is applied to the inverse of Gray (1980’s Conservatism Index – which allows you to compare the results between different accounting systems – to determine the impacts of the transition between the two phases of the convergence process in Brazil, covered by the law 11,638 and their CPCs. It was compared the 2009 financial results disclosed in BR GAAP and IFRS. Findings – The results show that the final stage of mandatory convergence to IFRS led to significant increases in both net income and the shareholders’ equity of the companies analysed: a mean increase of about 21% in earnings and about 11% in equity, as well as generating an increase, though somewhat less significant, about 7%, the total assets. Practical implications – This research helped to improve understanding of the impacts of convergence of Brazilian accounting to the international standard; as well as to assist business managers and users of financial information, especially those from the capital markets, regulators and academia, about the ultimate effects on the results reported in 2011, after the implementation of the final phase of convergence. Originality/value – The fiscal year of 2009 was a special year for understanding the impact of accounting system in the financial results disclosed in Brazil. The Brazilian publics companies reported their results in BR GAAP and IFRS and this research analysed and compare both reports and improve understanding of the impacts of convergence of Brazilian accounting to the international standard.

    The core performance impact of weapons plutonium introduction into the IFR closed fuel cycle is investigated by comparing three disposition scenarios: a power production mode, a moderate destruction mode, and a maximum destruction mode all at a constant heat rating of 840 MWt. For each scenario, two fuel cycle models are evaluated: cores using weapons material as the sole source of transuranics in a once-through mode, and recycle corns using weapons material only as required for a make-up feed. Calculated results include mass flows, detailed isotopic distributions, neutronic performance characteristics, and reactivity feedback coefficients. In general, it is shown that weapons plutonium feed does not have an adverse impact on IFR core performance characteristics

    2017-01-01

    Full Text Available The International Financial Reporting Standard 9 - IFRS is another one in the series of global level initiatives undertaken with a view to fixing the consequences of the global economic and financial crisis, and preventing the future negative developments caused by inadequate recognition and presentation of credit losses on the part of banks. The IFRS 9 also represents a significant shift in relation to traditional accounting, given that it introduced the concept of expected credit losses to replace the concept of occurred credit losses. This task cannot be fulfilled by the traditional and conservative accounting without involving the macroeconomic assessment models, i.e. macroeconomic scenarios. This paper aims to highlight some specific methodological rudiments in macroeconomic analyses and forecasts as inputs for the accounting recognition and presentation of expected credit losses.

    Full Text Available IFRS for SMEs is a change among of each entity, leading both to the positive and negative aspects regarding its application. Our study aims to present the perceptions of accounting experts on the application of IFRS for SMEs in Arad County. For the study was used the questionnaire based on resulted the pros and cons of applying standard responses to small and medium - sized entities, considering the law the main reason for applying standard. The Professional accountants believes that rules should have a major impact among listed entities, which leads to benefits and also difficulties. As benefits we enumerate improving, comparability and transparency of accounting information and as difficulties specify the auditing, the connection accountancy - fiscality and the report cost - benefit, but we cant fail to mention the lack of skilled personnel. Although there are a number of obstacles and costs as regards implementing IFRS for SMEs in Arad, and national level our respondents were equally agree with the application or non-application of this standard. We mention that the application of this standard requires more than a simple exercise because the rules used may have influenced in the content of the financial statements of the entity.

    Full Text Available This study aimed to assess the effect of adopting the International Financial Reporting Standards (IFRS in Brazil on the information relevance of accounting profits of publicly traded companies. International studies have shown that the adoption of IFRS improves the quality of accounting information compared with domestic accounting standards. Concurrent evidence is sparse in Brazil. Information relevance is understood herein as a multidimensional attribute that is closely related to the quality and usefulness of the information conveyed by accounting profits. The associative capacity and information timeliness of accounting profits in relation to share prices were examined. Furthermore, the level of conditional conservatism present in accounting profits was also analyzed because according to Basu (1997, this aspect is related to timeliness. The study used pooled regressions and panel data models to analyze the quarterly accounting profits of 246 companies between the first quarter of 1999 and the first quarter of 2013, resulting in 9,558 quarter-company observations. The results indicated that the adoption of IFRS in Brazil (1 increased the associative capacity of accounting profits; (2 reduced information timeliness to non-significant levels; and (3 had no effect on conditional conservatism. The joint analysis of the empirical evidence from the present study conclusively precludes stating that the adoption of IFRS in Brazil contributed to an increase the information relevance of accounting profits of publicly traded companies.

    Full Text Available This study examines the dynamics of the implementation of IFRS in Indonesia and challenges faced by its stakeholders by using interpretive-qualitative research paradigm. In-depth interviews, observations, and documentary analysis were used during data collection processes. The results were then cross-examined through triangulation. More specifically, this study attempts to identify problems arised during the implementation and the responses of the stakeholders. The authors hope that the findings can enrich the literatures about the interconnectedness among accounting, culture, language, and stakeholders’ interests in the context of developing countries, especially Indonesia. Our results indicate that there is an interdependence among the stakeholders (regulator, auditor, user, preparer, and higher education institutions in which there is no party that can individually ensure the successfulness of the IFRS implementation. Synergistic, long-term oriented collective efforts among those parties are required since they all have internal constraints that can inhibit the implementation. In addition, culture (including language exacerbates the problems and, hence, require long-term, strategic responses in macro level. Finally, this study suggests seven propositions conditioning the effectiveness of IFRS implementation in a national context.

Considering that the convergence process with the international standards aims for the standardization of accounting information disclosure and the enhancement of its quality, the goal was to investigate the quality standards of the accounting information in Brazilian companies after the adoption of the IFRS in the phases characterized by the period 2008, when accounting pronouncements (CPC 1 to 14 were adopted, and as from 2010, when the adoption of the full IFRS became compulsory. Therefore, a sample of financial statements was used from 320 companies listed on BM&FBOVESPA between 2000 and 2012. As a proxy of information quality, the attribute Conservatism was used, as proposed by Basu (1997 and Ball and Shivakumar (2005. The results did not evidence changes in the degree of conservatism in the statements analyzed.

  14. Recycling option search for a 600 MWE sodium-cooled transmutation fast reactor

    2015-02-15

    Four recycling scenarios involving pyroprocessing of spent fuel (SF) have been investigated for a 600-MWe transmutation sodium-cooled fast reactor (SFR), KALIMER. Performance evaluation was done with code system REBUS connected with TRANSX and TWODANT. Scenario Number 1 is the pyroprocessing of Canada deuterium uranium (CANDU) SF. Because the recycling of CANDU SF does not have any safety problems, the CANDU-Pyro- SFR system will be possible if the pyroprocessing capacity is large enough. Scenario Number 2 is a feasibility test of feed SF from a pressurized water reactor PWR. The sensitivity of cooling time before prior to pyro-processing was studied. As the cooling time increases, excess reactivity at the beginning of the equilibrium cycle (BOEC) decreases, thereby creating advantageous reactivity control and improving the transmutation performance of minor actinides. Scenario Number 3 is a case study for various levels of recovery factors of transuranic isotopes (TRUs). If long-lived fission products can be separated during pyroprocessing, the waste that is not recovered is classified as low- and intermediate-level waste, and it is sufficient to be disposed of in an underground site due to very low-heat-generation rate when the waste cooling time becomes >300 years at a TRU recovery factor of 99.9%. Scenario Number 4 is a case study for the recovery factor of rare earth (RE) isotopes. The RE isotope recovery factor should be lowered to 20% in order to make sodium void reactivity less than <7$, which is the design limit of a metal fuel.

    1995-01-01

    Several performance assessment (PA) analyses have been completed to estimate the release to the accessible environment of radionuclides from spent light water reactor (LWR) fuel emplaced in the proposed Yucca Mountain repository. Probabilistic methods were utilized based on the complexity of the repository system. Recent investigations have been conducted to identify the merits of a pyroprocess fuel cycle. This cycle utilizes high temperature molten salts and metals to partially separate actinides and fission products. In a closed liquid metal reactor (LMR) fuel cycle, this allows recycling of nearly all of the actinides. In a once-through cycle, this isolates the actinides for storage into a wasteform which can be specifically tailored for their retention. With appropriate front-end treatment, this Process can also be used to treat LWR spent fuel

    Full Text Available At the level of the European financial system, banks are the basic institutions which provide financing for the private sector, it preferring bank financing at the expense of financing through the capital market. The current stage of the international accounting harmonisation process focuses on obtaining similar economic decisions taken by investors and other users of the financial statements – decisions based on equivalent financial statements, prepared according to the set of International Financial Reporting Standards - IFRS developed by the IASB. Therefore, the aim of this study is to provide an overview of the implementation of IFRS in the world as well as in Romania by providing some information about the adoption process and the issues identified through the implementation of IFRS, especially in the banking field in Romania.

    2011-07-01

    Full Text Available The mandatory use of IFRS by all publicly listed companies in the European Union created challenges for accounting and reporting of business combinations, goodwill impairment and disclosures for these items. Major issues are allocation of amounts to goodwill and specific intangible assets arising from acquisition. This study presents an in-depth exploration of compliance with IFRS 3 and IAS 36 using content analysis methodology of annual reports of eight European telecommunications that were chose because the industry is well known for significant acquisitions involving intangibles. The results show only partial compliance with little change over the four year period since mandatory IFRS adoption. While results cannot be generalized outside this group, the in-depth analysis yielded important insights for continued research using broader research methods.

    1996-01-01

    Interdiffusion experiments have been conducted to investigate the compatibility of various austenitic stainless steels with U-Pu-Zr alloys, which are alloys to be employed as fuel for the Integral Fast Reactor being developed by Argonne National Laboratory. These tests have also studied the compatibility of austenitic stainless steels with fission products, like the minor actinides (Np and Am) and lanthanides (Ce and Nd), that are generated during the fission process in an IFR. This paper compares the results of these investigations in the context of fuel-cladding compatibility in IFR fuel elements, specifically focusing on the relative Interdiffusion behavior of the components and the types of phases that develop based on binary phase diagrams. Results of Interdiffusion tests are assessed in the light of observations derived from post-test examinations of actual irradiated fuel elements

  4. IFRS, synchronicity, and financial crisis: the dynamics of accounting information for the Brazilian capital market

    Directory of Open Access Journals (Sweden)

    Bruno Figlioli

    2017-07-01

    Full Text Available ABSTRACT This study aims is to investigate the synchronicity levels of shares traded on the spot market of the São Paulo Stock, Commodities , and Futures Exchange (BM&FBOVESPA in relation to the accounting convergence process towards International Financial Reporting Standards (IFRS in Brazil. The term synchronicity refers to the amount that company-specific information and market information are reflected in stock prices. The more share prices reflect company-specific information rather than market information, the greater the informational content of these prices will be in terms of representing the economic value of a particular company. For this investigation, information on companies and shares from 2005 to 2015 was collected, excluding the financial sector. The data were analyzed using cross-sectional and panel regressions. The results indicate a reduction in the synchronicity levels of stocks in the period of full adoption of IFRS in Brazil from 2010 onwards. From 2008 to 2009, which includes the partial adoption of IFRS in Brazil, statistically significant results were not found for the synchronicity levels of shares. However, for times of financial crisis, evidence was found of a reduction in the relevance of accounting information even with the adoption of international accounting standards. The results obtained for the Brazilian context do not support the idea that the adoption of IFRS necessarily causes an increase in the informational content of financial statements and that relevant information is consequently reflected in stock prices.

    Full Text Available É compreensível que devido a relevância dos relatórios contábeis e sua maior importância com a adoção das IFRS haja nas empresas uma preocupação com os fatores que causam interferência na sua qualidade, bem como, com os critérios utilizados na sua formação, consistência e avaliação. Dentre os fatores que exercem influencia na qualidade das informações contábeis está o conservadorismo, definido por Basu (1997 como um reconhecimento assimétrico das perdas em relação aos ganhos, se refletem as más notícias mais rapidamente do que as boas notícias. Considerando este contexto, o presente estudo tem o objetivo de avaliar as magnitudes das influências das IFRS nos níveis de conservadorismo contábil das práticas adotadas nos países membros do GLENIF, mais especificadamente, Argentina, Brasil, Chile, Colômbia, México e Peru no período de 2003 a 2013. Com uma amostra de 513 empresas e 5643 observações, aplicou-se por meio de dados em painel a equação original de Basu (1997 e, posteriormente, incluiu-se uma variável dummy considerando os efeitos da adoção das IFRS no conservadorismo. Os resultados indicaram que, mesmo com a adoção das IFRS notou-se no Brasil e no México a presença de práticas conservadoristas. Na Argentina constatou-se situação contrária, as IFRS amenizaram o conservadorismo nas empresas do país. Já no Chile, Colômbia e Peru os resultados não significativos foram insuficientes para indicarem a presença de conservadorismo após a adoção das IFRS.

    One of the final products of pyroprocessing for spent nuclear fuel recycling is a U/TRU ingot consisting of rare earth (RE), uranium (U), and transuranic (TRU) elements. The amounts of nuclear materials in a U/TRU ingot must be measured as precisely as possible in order to secure the safeguardability of a pyroprocessing facility, as it contains the most amount of Pu among spent nuclear fuels. In this paper, we propose a new nuclear material accountancy method for measurement of Pu mass in a U/TRU ingot. This is a hybrid system combining two techniques, based on measurement of neutrons from both (1) fast- and (2) thermal-neutron-induced fission events. In technique #1, the change in the average neutron energy is a signature that is determined using the so-called ring ratio method, according to which two detector rings are positioned close to and far from the sample, respectively, to measure the increase of the average neutron energy due to the increased number of fast-neutron-induced fission events and, in turn, the Pu mass in the ingot. We call this technique, fast-neutron energy multiplication (FNEM). In technique #2, which is well known as Passive Neutron Albedo Reactivity (PNAR), a neutron population's changes resulting from thermal-neutron-induced fission events due to the presence or absence of a cadmium (Cd) liner in the sample's cavity wall, and reflected in the Cd ratio, is the signature that is measured. In the present study, it was considered that the use of a hybrid, FNEM×PNAR technique would significantly enhance the signature of a Pu mass. Therefore, the performance of such a system was investigated for different detector parameters in order to determine the optimal geometry. The performance was additionally evaluated by MCNP6 Monte Carlo simulations for different U/TRU compositions reflecting different burnups (BU), initial enrichments (IE), and cooling times (CT) to estimate its performance in real situations.

    The lifetime of the Ion Focusing Regime (IFR) channel following the pulsing of the post-accelerating gaps is critical for an open-ended, spiral recirculating electron linear accelerator. It dictates the number of allowable beam recirculations through the gap. In the case of a racetrack configuration, its is significant but not as critical, since the presence of the electron beam focuses the ions and lengthens the lifetime of the ion channel. It was established that pulsing the accelerating gap perturbs the IFR channel. However, for the parameters studied, the lifetime is long enough to allow at least four beam recirculations in a spiral device. In addition, cusp fields positioned upstream and downstream from the gap prevent it from perturbing the IFR channel

  18. USING CENTER HOLE HEAT TRANSFER TO REDUCE FORMATION TIMES FOR CERAMIC WASTE FORMS FROM PYROPROCESSING

    2006-01-01

    The waste produced from processing spent fuel from the EBR II reactor must be processed into a waste form suitable for long term storage in Yucca Mountain. The method chosen produces zeolite granules mixed with glass frit, which must then be converted into a solid. This is accomplished by loading it into a can and heating to 900 C in a furnace regulated at 915 C. During heatup to 900 C, the zeolite and glass frit react and consolidate to produce a sodalite monolith. The resultant ceramic waste form (CWF) is then cooled. The waste is 52 cm in diameter and initially 300 cm long but consolidates to 150 cm long during the heating process. After cooling it is then inserted in a 5-DHLW/DOE SNF Long Canister. Without intervention, the waste takes 82 hours to heat up to 900 C in a furnace designed to geometrically fit the cylindrical waste form. This paper investigates the reduction in heating times possible with four different methods of additional heating through a center hole. The hole size is kept small to maximize the amount of CWF that is processed in a single run. A hole radius of 1.82 cm was selected which removes only 1% of the CWF. A reference computation was done with a specified inner hole surface temperature of 915 C to provide a benchmark for the amount of improvement which can be made. It showed that the heatup time can potentially be reduced to 43 hours with center hole heating. The first method, simply pouring high temperature liquid aluminum into the hole, did not produce any noticeable effect on reducing heat up times. The second method, flowing liquid aluminum through the hole, works well as long as the velocity is high enough (2.5 cm/sec) to prevent solidification of the aluminum during the initial front movement of the aluminum into the center hole. The velocity can be reduced to 1 cm/sec after the initial front has traversed the ceramic. This procedure reduces the formation time to near that of the reference case. The third method, flowing a gas

    The molten salt waste from a pyroprocess to recover uranium and transuranic elements is one of the problematic radioactive wastes to be solidified into a durable wasteform for its final disposal. By using a novel method, named as the GRSS (gel-route stabilization/solidification) method, a molten salt waste was treated to produce a unique wasteform. A borosilicate glass as a chemical binder dissolves the silicate compounds in the gel products to produce one amorphous phase while most of the phosphates are encapsulated by the vitrified phase. Also, Cs in the gel product is preferentially situated in the silicate phase, and it is vitrified into a glassy phase after a heat treatment. The Sr-containing phase is mainly phosphate compounds and encapsulated by the glassy phase. These phenomena could be identified by the static and dynamic leaching test that revealed a high leach resistance of radionuclides. The leach rates were about 10(-3) - 10(-2) g/m2 x day for Cs and 10(-4) - 10(-3) g/m2 x day for Sr, and the leached fractions of them were predicted to be 0.89% and 0.39% at 900 days, respectively. This paper describes the characteristics of a unique wasteform containing a molten salt waste and provides important information on a newly developed immobilization technology for salt wastes, the GRSS method.

    Full Text Available January 2014 was set to be the take-off period for Nigerian SMEs to adopt IFRS. As Nigeria enters the transition phase of IFRS adoption for SMEs, there is a need to assess the level of preparedness for adoption, which is the focus of this paper. The population of the study is the SME proprietors in Nigeria, but samples were selected from Lagos, because of constraints in covering the entire 36 states of the country. Data was collected through self-administered questionnaires, by requesting SME proprietors to provide ranking on a 1-4 scale, on issues stemming from IFRS adoption by SMEs. Cluster sampling technique was used to administer 200 copies of the research instrument in two cluster sites having a proliferation of SMEs in Lagos— Alaba International Market in Ojo local government and Computer Village in Ikeja.141 copies of the instrument were retrieved but 136 copies found usable for analysis. Percentage Analysis, Mean, Standard deviation and factor analysis (using the principal component analysis extraction method were used for analysis. A model for preparedness for IFRS adoption was formulated by regressing the factors influencing adoption on the level of preparedness. Results show that there is the need for IFRS adoption by SMEs in Nigeria because of the expected benefits to accrue. The level of preparedness for IFRS adoption (M= 2.32, SD=1.032 was however found to be low.

The study adopted mixed research approach. Questionnaires and unstructured interviews were used as research instruments to collect primary data. Content analysis was also adopted to triangulate the results. Target population was the listed companies in Zimbabwe. The study found a significant negative relationship between voluntary adoption of IFRS and earnings management of listed companies in Zimbabwe. The negative relationship may indicate that IFRS does not promote earnings management for voluntary adopters, thereby implying an increased financial reporting quality. It is recommended that top management, external auditors and regulators being the key players in standards, should work together and tighten compliance so that impact of IFRS could be felt more

    The electrorefining process, which is a key process in pyroprocessing, is composed of two parts, electrorefining to deposit a uranium with a solid cathode and electrowinning to co-deposit TRU and RE with a liquid cadmium cathode (LCC). As the electrorefining operation proceedes, TRU and RE are accumulated in electrolyte LiCl-KCl salt, and after the electrorefining process, the molten salt used in an electrorefining reactor should by transported to the next process, the electrowinning process, to recover U/TRU/RE; Thus, a molten salt transfer system by suction is now being developed. An apparatus for suction transport experiments was designed and constructed for the development of high- temperature molten salt transport technology. Suction transport experiments were performed using LiC-KCl eutectic salt. The feasibility of pyro-reprocessing has been demonstrated through many laboratory-scale experiments. In pyroprocessing, a eutectic LiCl-KCl salt was used as a liquid elextrolyte for a recovery of actinides. However, reliable transport technologies for these high temperature liquids have not yet been developed.

    A three-part study is conducted using the MCNP6 Monte Carlo radiation-transport code to calculate delayed-neutron (DN) and delayed-gamma (DG) emission signatures for nondestructive assay (NDA) metal-fuel pyroprocessing. In Part 1, MCNP6 is used to produce irradiation-induced used nuclear fuel (UNF) isotopic inventories for an Argonne National Laboratory (ANL) Advanced Burner Test Reactor (ABTR) preconceptual design fuel assembly (FA) model. The initial fuel inventory consists of uranium mixed with light-water-reactor transuranic (TRU) waste and 10 wt% zirconium (U-LWR-SFTRU-10%Zr). To facilitate understanding, parametric evaluation is done using models for 3% and 5% initial 235U a% enrichments, burnups of 5, 10, 15, 20, 30, …, 120 GWd/MTIHM, and 3-, 5-, 10-, 20-, and 30- year cooling times. Detailed delayed-particle radioisotope source terms for the irradiate FA are created using BAMF-DRT and SOURCES3A. Using simulation tallies, DG activity ratios (DGARs) are developed for 134Cs/137Cs 134Cs/154Eu, and 154Eu/137Cs markers as a function of (1) burnup and (2) actinide mass, including elemental uranium, neptunium, plutonium, americium, and curium. Spectral-integrated DN emission is also tallied. The study reveals a rich assortment of DGAR behavior as a function of DGAR type, enrichment, burnup, and cooling time. Similarly, DN emission plots show variation as a function of burnup and of actinide mass. Sensitivity of DGAR and DN signatures to initial 235U enrichment, burnup, and cooling time is evident. Comparisons of the ABTR radiation signatures and radiation signatures previously reported for a generic Westinghouse oxide-fuel assembly indicate that there are pronounced differences in the ABTR and Westinghouse oxide-fuel DN and DG signatures. These differences are largely attributable to the initial TRU inventory in the ABTR fuel. The actinide and nonactinide inventories for the

  11. Hedge accounting under IFRS 9: an analysis of reforms

    2017-02-01

    Full Text Available Pronouncements of regulatory bodies on ‘hedge accounting’ are aimed at ensuring that impact of price changes of hedging relationships are accounted for concurrently. However, it sometimes happens that certain provisions of these standards result in the reporting of enhanced earnings volatility being attributed to hedging relationships which is not economically justified. It is often perceived to be the case by stakeholders that the provisions of IAS 39 on ‘hedge accounting’ do not appropriately reflect and are not aligned with the risk management strategies of entities that attempt to mitigate risk using various hedging relationships. This occasionally results in a reporting entity adopting either a suboptimal hedging strategy that gives it eligibility to account for it using ‘hedge accounting’ or vice versa. Thus entities may be faced with the tradeoff between the benefits of risk mitigation strategies and the benefits derived from adopting ‘hedge accounting’. This motivated the IASB to initiate action for the complete reformulation of the standard on ‘hedge accounting’. The revised standard was pronounced in November 2013 as IFRS 9. In this article, we attempt to evaluate the upgradations introduced by IFRS 9 over its predecessor, IAS 39, with particular reference to the reporting of risk management strategies of affected entities.

Pesquisas realizadas con empresas de capital abierto, en varios países del mundo, indican que esa nueva norma tiende a mejorar la calidad de la información y dejarla más comparable y transparente. Frente a eso, el estudio tiene como objetivo verificar si ha habido mudanza en los niveles de gerenciamiento de resultados después de 2010 y si fue en función de la adopción completa de las IFRS por las compañías brasileñas de capital abierto (con excepción de las instituciones financieras. Los datos fueron extraídos de las demostraciones contables trimestrales de los bancos de datos del Economática y de la Comisión de Valores Mobiliarios referentes al período de 2006 a 2011. Para alcanzar el objetivo de la pesquisa, fueron efectuados dos tests. El primero mostró que los accruals discrecionales, calculados por medio del Modelo de Jones Modificado, tuvieron media menor después de 2010. A continuación, fue elaborado el análisis de regresión con datos dispuestos en panel con corrección de Newey-West. Los resultados no confirmaron la hipótesis de que la adopción de las IFRS afectó al nivel de gerenciamiento de resultados en el período analizado, pero mostraron que el tamaño y el endeudamiento explican significativamente los accruals discrecionales, independientemente de la adopción de las IFRS. Los resultados sugieren que empresas mayores y con elevada proporción de capital propio tienden a producir informes con mejor calidad, independientemente de la adopción de las IFRS.

  15. The possible ways to IFRS (International Financial Reporting Standards for SME (Small and Medium sized Entities development

    Directory of Open Access Journals (Sweden)

    Hana Bohušová

    2007-01-01

    Full Text Available The most business entities in Europe are small or medium-sized enterprises (SME, which have a legal obligation to prepare financial statements in accordance with a set of accounting principles accepted in their country. Those statements are available to creditors, suppliers, and national governments but they could be badly understandable to creditors, suppliers and subjects in other countries. This is a great obstacle of their activities in the EU internal market. The existence of 27 different national accounting systems in the EU can be held for the most important obstacle.There are many ways how to develop compatible accounting standards for SMEs but the most significant activity in this field is the research project of IASB (International Accounting Standards Board. IASB has developed IFRS (International Financial Reporting Standards. Even though IFRS are suitable for all enterprises, their application in case of SMEs would be very expensive and could significantly increase compliance costs of taxation. This development has not been finished yet and there are still some problems which need to be solved before the introduction of accounting standards to the public. The research has shown that IFRS for SMEs should be used mainly by the entities which do not have public accountability – i.e. that its equities are not publicly traded and do not hold assets in a fiduciary capacity for a broad group of outsiders. This paper discusses those IFRS modifications, which should be done in case of SMEs.

    Sodium aluminum (iron) phosphate glass ceramics containing of up to 20 wt.% rare earth (RE) oxides simulating pyroprocessing waste were produced by melting at 1250 °C followed by either quenching or slow cooling to room temperature. The iron-free glass-ceramics were composed of major glass and minor phosphotridymite and monazite. The iron-bearing glass-ceramics were composed of major glass and minor monazite and Na-Al-Fe orthophosphate at low waste loadings (5-10 wt.%) and major orthophosphate and minor monazite as well as interstitial glass at high waste loadings (15-20 wt.%). Slowly cooled samples contained higher amount of crystalline phases than quenched ones. Monazite is major phase for REs. Leach rates from the materials of major elements (Na, Al, Fe, P) are 10-5-10-7 g cm-2 d-1, RE elements - lower than 10-5 g cm-2 d-1.

    An intense relativistic electron beam (IREB) injected into neutral gas in the high pressure regime characteristically propagates in a self-pinched mode but is susceptible to the resistive hose instability. Typically, beam are conditioned for propagation experiments by reducing the perturbations that may excite resistive hose and by adjusting the emittance profile of the beam such that the convective growth of the instability is decreased. The former has been achieved by applying an anharmonic focusing force as the beam is transported through a conducting tube or cell. The latter has been effectively demonstrated by passing the beam through an ion focus regime (IFR) cell which imposes a head to tail beam emittance variations. However, since the physical parameters of the two types of cells are different, conflicts arise when the cells are coupled sequentially. The double-wall IFR cell described here eliminates these interface difficulties by providing the necessary conditions properties in a single cell. The physics and design of the cell will be introduced and parameter variations explored. The conditioning and propagation measurements will be presented and the results of the experiment will be discussed in relation to theory and simulation

    Full Text Available The article presents the results of a survey conducted among a carefully selected group of Polish certified auditors. The purpose of the study was to determine whether auditors, during the audit of financial state- ments, perceive certain costs and benefits resulting from the fact that the audited statements were pre- pared in accordance with IFRS. This survey was undertaken to demonstrate that the cost-benefit analysis of IFRS, after more than a decade of their use in Polish practice, could provide important observations for future legislative changes in this area. The study shows that, thanks to the implementation of IFRSs, auditors gain the benefit of lower audit workloads. At the same time, however, they identify six reasons why the audit process is prolonged, requiring special organization, prior special preparation and, as a result, higher auditing costs

    Full Text Available International accounting convergence is a highly complex process that began decades ago, emphasized globalization being the main factor that determined setters, professional bodies, investors to become aware of the importance of completing this process, namely the development and implementation of a common set of standards covering all areas of financial reporting. This objective was initially assumed by the International Accounting Standards Committee (IASC, now the International Accounting Standards Board (IASB.In this respect, at first it is noted the convergence of U.S. standards with the international ones, respectively the convergence of U.S. GAAP - IFRS standards, that, at least in theory, are not so different from each other, as we can say that, just as IFRS, U.S. GAAP were designed as a system of principles-based accounting. In reality, the U.S. standards system has proven to be more of a rules-based accounting system, unlike his international equivalent/counterpart. And the current state of convergence of the two sets of rules still reflects significant differences, plus the opposition of some entities to accept international standards.

    Full Text Available This article offer an overview of the characteristics of IFRS 15 requirements regarding revenue. Revenue is the gross inflow of economic benefits during the period arising in the course of the ordinary activities of an entity when those inflows result in increases in equity, other than increases relating to contributions from equity participants. This new standard intends to cover the gaps from the previous standards such as IAS 18 and IAS 11. IAS 18 provided limited guidance on many important revenue topics such as accounting for multiple-element arrangements. Fair value measurement and impairment methodology based on the incurred loss model are discussed in this context. This new standard offers detailed guidelines for different type of transactions such as sale with a right of return, like non-refundable upfront fees (and some related costs, principal versus agent considerations and consignment arrangements, others. Based on the results of this analysis, will show these views suggest practitioners ‘confusion about IFRS 15.

    Full Text Available Several changes in the legislation governing accounting practices of construction sector companies boosted the internationalization of information on revenues of customer contracts in accounting. Brazil has stood out for early voluntary adoption of IFRS15 standard. Thus, the study aims to determine the relationship between the quality of accounting information and the early adoption of IFRS 15 by Brazilian construction companies listed on BM &FBovespa. The study is characterized as descriptive, conducted through document analysis and quantitative approach. The sample consists of 23 companies in the construction sector. Were analyzed quarterly data from 2013 to 2015. For the data analysis was made using multiple linear regression with panel data, on the basis of accounting information for quality measurement model of value relevance proposed by Ohlson (1995. The survey results suggest that early adoption of IFRS15 helps to reduce the bias of non-comparability and inconsistencies that could exist previously, due to the adoption of different criteria for accounting of revenues on construction contracts. In addition, organizations that voluntarily adopt the rule in an attempt to account for and properly recognize customer contracts revenue, have greater informational relevance and meet market expectations. Thus, it can be said that the early adoption of information on revenue from construction contracts have relevance to the capital market, impacting the stock price after the publication of financial reports.

    1983-01-01

    An analysis of incident data obtained from the NASA Aviation Safety Reporting System (ASRS) has been made to determine the problem areas in general aviation single-pilot IFR (SPIFR) operations. The Aviation Safety Reporting System data base is a compilation of voluntary reports of incidents from any person who has observed or been involved in an occurrence which was believed to have posed a threat to flight safety. This paper examines only those reported incidents specifically related to general aviation single-pilot IFR operations. The frequency of occurrence of factors related to the incidents was the criterion used to define significant problem areas and, hence, to suggest where research is needed. The data was cataloged into one of five major problem areas: (1) controller judgment and response problems, (2) pilot judgment and response problems, (3) air traffic control (ATC) intrafacility and interfacility conflicts, (4) ATC and pilot communication problems, and (5) IFR-VFR conflicts. In addition, several points common to all or most of the problems were observed and reported. These included human error, communications, procedures and rules, and work load.

    Full Text Available The accounting rules from each country evolve in time in order to respond the social, cultural and economical environment needs. After some communist countries (as Romania, Bulgaria, Poland, Hungary, Czech Republic, Slovenia, Estonia, Lithuania, s.o. joined the European Union an important number of local companies became to apply accounting regulation according with International Financial Reporting Standards (IFRS. This paper surveys the theoretical and empirical literature on the possible risks for companies management from ex-communist counties by applying (mandatory or voluntary International Financial Reporting Standards reporting regulation and professional judgment. Under the pressure of economic globalization all the ex-communist countries ware obliged to adopt International Financial Reporting Standards in the field of accounting. The main objective of this paper is to find out from the experience of different companies who already adopted IFRS which are the risks related to professional judgment application under IFRS on the financial statement users. As research methodology we integrated theoretical and empirical studies from accounting and law (especially from Romanian experience in order to contribute to the cross-fertilization of our field of interest. As final results of our paper we find that the biggest risk of applying professional judgment prescribed by IFRS in ex-communist countries is to appear different creative accounting techniques which influence in a negative way the decision-making process for the financial statements users. During worldwide financial crisis the majority of Romanian companies tried to use in the most appropriate way the professional judgment in order to arrange their financial reports and to save company's money (in relation with local government or to show higher performance (in relation with financial institutions for the fund-raising process We identified several motivations including the existence

    2018-01-01

    In order to improve the efficiency of intumescent flame retardants (IFRs), a novel macromolecular charring agent named poly(ethanediamine-1,3,5-triazine-p-4-amino-2,2,6,6-tetramethylpiperidine) (PETAT) with gas phase and condense phase synergistic flame-retardant capability was synthesized and subsequently dispersed into polypropylene (PP) in combination with ammonium polyphosphate (APP) via a melt blending method. The chemical structure of PETAT was investigated by Fourier transform infrared spectroscopy (FTIR), and 1H nuclear magnetic resonance (NMR) spectroscopy. Thermal properties of the PETAT and IFR systems were tested by thermogravimetric-derivative thermogravimetric analysis (TGA-DTG) and thermogravimetry–Fourier transform infrared spectroscopy (TG-FTIR). The mechanical properties, thermal stability, flame-retardant properties, water resistance, and structures of char residue in flame-retardant composites were characterized using tensile and flexural strength property tests, TGA, limiting oxygen index (LOI) values before and after soaking, underwritten laboratory-94 (UL-94) vertical burning test, cone calorimetric test (CCT), scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDXS), and FTIR. The results indicated that PETAT was successfully synthesized, and when the ratio of APP to PETAT was 2:1 with 25 wt % loading, the novel IFR system could reduce the deterioration of tensile strength and enhance the flexural strength of composites. Meanwhile, the flame-retardant composite was able to pass the UL-94 V-0 rating with an LOI value of 30.3%, and the peak of heat release rate (PHRR), total heat release (THR), and material fire hazard values were considerably decreased compared with others. In addition, composites also exhibited excellent water resistance properties compared with traditional IFR composites. SEM-EDXS and FTIR analyses of the char residues, as well as TG-FTIR analyses of IFR were used to investigate the flame

    The invention is a process for the removal of rare earths from molten chloride electrolyte salts used in the reprocessing of integrated fast reactor fuel (IFR). The process can be used either continuously during normal operation of the electrorefiner or as a batch process. The process consists of first separating the actinide values from the salt before purification by removal of the rare earths. After replacement of the actinides removed in the first step, the now-purified salt electrolyte has the same uranium and plutonium concentration and ratio as when the salt was removed from the electrorefiner. 1 fig

    Full Text Available The electrochemical reduction process has been used to reduce spent oxide fuel to a metallic form using pyroprocessing technology for a closed fuel cycle in combination with a metal-fuel fast reactor. In the electrochemical reduction process, oxides fuels are loaded at the cathode basket in molten Li2O–LiCl salt and electrochemically reduced to the metal form. Various approaches based on thermodynamic calculations and experimental studies have been used to understand the electrode reaction and efficiently treat spent fuels. The factors that affect the speed of the electrochemical reduction have been determined to optimize the process and scale-up the electrolysis cell. In addition, demonstrations of the integrated series of processes (electrorefining and salt distillation with the electrochemical reduction have been conducted to realize the oxide fuel cycle. This overview provides insight into the current status of and issues related to the electrochemical processing of spent nuclear fuels.

    A compact, efficient method for conditioning spent nuclear fuel is under development This method, known as pyrochemical processing, or open-quotes pyroprocessing,close quotes provides a separation of fission products from the actinide elements present in spent fuel and further separates pure uranium from the transuranic elements. The process can facilitate the timely and environmentally-sound treatment of the highly diverse collection of spent fuel currently in the inventory of the United States Department of Energy (DOE). The pyroprocess utilizes elevated-temperature processes to prepare spent fuel for fission product separation; that separation is accomplished by a molten salt electrorefining step that provides efficient (99.9%) separation of transuranics. The resultant waste forms from the pyroprocess are stable under envisioned repository environment conditions and highly leach-resistant. Treatment of any spent fuel type produces a set of common high-level waste forms, one a mineral and the other a metal alloy, that can be readily qualified for repository disposal and preclude the substantial costs that would be associated with the qualification of the numerous spent fuel types included in the DOE inventory

    Full Text Available An issue of relationship between corporate income tax and accounting is one of the most discussed at present. Until recently the tax base was derived from the accounting profit defined in the Czech accounting law. But from 2004 there are companies which have to use IFRS in bookkeeping and financial reporting and from the perspective of the Czech accounting law they do not care about Czech accounting regulation. On the other hand Czech tax regulation has not accepted this change in the field of European accounting harmonization and still directs to pay tax on the basis of Czech accounting regulation for all entities. Fear of adverse change in tax collection is one of the main reasons why the Czech Tax Administration does not allow to pay income tax under profit or loss patterned on IFRS. The most important goal of this work is to characterize the relationship between accounting profit or loss under IFRS and the tax base of income and to find out the impact of taxation under profit in accordance with IFRS in total tax collection. Basic sample of all analyses consists of 35 accounting entities which mandatorily use IFRS and this sample was also confronted with a list of 106 major payers of income tax published yearly by the Ministry of Finance of the Czech Republic for the needs characterization of the relationship of profit under IFRS and the tax base of income.

    Full Text Available An agreement from Norwalk was issued in September 2002 on the basis of negotiations of Financial Accounting Standards Board (FASB a International Accounting Standards Board (IASB for the elimination of restrictions in the form of two different systems of financial reporting. The aim is to ensure absolute compatibility of existing U.S. GAAP and IFRS and the coordination of work programs in the future. Document Memorandum of Understanding was issued in 2006 in the frame of ongoing process of convergence, in which the FASB and IASB confirm their intention to create high-quality and global financial reporting standards. In this document there are specified areas, which would lead to convergence of procedures.Borrowing costs have been one from the fields, which was the subject of convergence works. U.S. GAAP dictated capitalization of borrowing costs incurred in connection with the acquisition of qualifying assets, while the IAS/IFRS leaved the decision on accounting entities, how it recognize and record borrowing costs incurred in connection with the acquisition of the assets.In the beginning, the method of analysis and description is used to identify and describe the basic difference of both systems, which had existed before the initiation of convergence within the frame of “Borrowing Costs” project. The above mentioned primary analysis has served as the basis for the further comparative analysis and synthesis.The paper further presents comparative analysis of two basic methodical approaches towards the borrowing costs reporting incurred in relation to the acquisition of the qualifying assets, which was possible to apply until 31st Dec 2008 under IFRS system.The comparative analysis is based on empirical company data. The subjects are mainly the differences in the indicators, which are used for the evaluation of the company financial situation.

However, if the companies, which have adopted International Financial Reporting Standards (IFRS globally, cannot generate the same information then the accounting practices need to be improved. For this purpose, the current study was performed with the objectives of measuring relationship between profitability and market capitalization and to analyze the challenges faced by listed firms of various countries in association with the implementation of IFRS. For this purpose, 15 companies were selected from 5 countries including India, China, Germany, Russia and Kenya. The secondary data regarding the correlation between profitability and market capitalization were analyzed to calculate the correlations. The primary data regarding the managers perception were analyzed with multiple regression method using SPSS-19 software to find out the company related variables, investors’ related variables and government agency related variables responsible for problems in the current adoption of IFRS.

    Implementing international and domestic accounting standards is very difficult. This calls for a discussion referring to the opportunity of adopting standards from other cultures- mentalities deeply rooted into principles- hence the difficulty to implement. Implementing IFRS means more than a simple change of accounting regulations. It represents a new assessment of performance that must be implemented into the entire entity. This new system might enforce decisive changes regarding accounting...

    During the pyroprocessing, most of the uranium is gathered in metallic form around a solid cathode during an electro-refining process, which is composed of about 94 weight percent of the spent fuel. In the previous study, a feasibility study has been done to reuse the recovered uranium for the CANDU reactor fuel following the traditional DUPIC (direct use of spent pressurized water reactor fuel into CANDU reactor) fuel fabrication process. However, the weight percent of U-235 in the recovered uranium is about 1 wt% and it is sufficiently re-utilized in a heavy water reactor which uses a natural uranium fuel. The reuse of recovered uranium will bring not only a huge economic profit and saving of uranium resources but also an alleviation of the burden on the management and the disposal of the spent fuel. The research on recycling of recovered uranium was carried out 10 years ago and most of the recovered uranium was assumed to be imported from abroad at that time. The preliminary results showed there is the sufficient possibility to recycle recovered uranium in terms of a reactor's characteristics as well as the fuel performance. However, the spent CANDU fuel is another issue in the storage and disposal problem. At present, most countries are considering that the spent CANDU fuel is disposed directly due to the low enrichment (∼0.5 wt%) of the discharge fissile content and lots of fission products. If mixing the spent CANDU fuel and the spent PWR fuel, the estimated uranium fissile enrichment will be about 0.6 wt% ∼ 1.0 wt% depending on the mixing ratio, which is sufficiently reusable in a CANDU reactor. Therefore, this paper deals with a feasibility study on the recovered uranium of the mixed spent fuel from the pyroprocessing. With the various mixing ratios between the PWR spent fuel and the CANDU spent fuel, a reactor characteristics including the safety parameters of the CANDU reactor was evaluated

    Full Text Available Abstract Background Enzymes belonging to the same super family of proteins in general operate on variety of substrates and are inhibited by wide selection of inhibitors. In this work our main objective was to expand the scope of studies that consider only the catalytic and binding pocket amino acids while analyzing enzyme specificity and instead, include a wider category which we have named the Interface Forming Residues (IFR. We were motivated to identify those amino acids with decreased accessibility to solvent after docking of different types of inhibitors to sub classes of serine proteases and then create a table (matrix of all amino acid positions at the interface as well as their respective occupancies. Our goal is to establish a platform for analysis of the relationship between IFR characteristics and binding properties/specificity for bi-molecular complexes. Results We propose a novel method for describing binding properties and delineating serine proteases specificity by compiling an exhaustive table of interface forming residues (IFR for serine proteases and their inhibitors. Currently, the Protein Data Bank (PDB does not contain all the data that our analysis would require. Therefore, an in silico approach was designed for building corresponding complexes The IFRs are obtained by "rigid body docking" among 70 structurally aligned, sequence wise non-redundant, serine protease structures with 3 inhibitors: bovine pancreatic trypsin inhibitor (BPTI, ecotine and ovomucoid third domain inhibitor.

    Full Text Available This paper represents a study on the implementation of the international accounting standards in Romania. Through this paper we find out about the stages covered and the solutionsadopted by Romania as well as the perspectives concerning the adaptability of the national accounting system to the performance of the international standards in the accounting domain, namely: the elaboration of accounting regulations harmonized with International Accounting Standards or, in other words, the internationalization of the national accounting system; ensuring the compliance of Romanian accounting regulations with the European directives and, in consequence,waiving the International Accounting Standards (at least at declarative level for the financial reporting in relation to the state institutions; the transition to the gradual implementation of International Accounting Standards/Financial Reporting (IAS/IFRS. We made also some assessments on the perspectives of using IAS/IFRS as a unique set of norms (as accounting basis for the preparation of individual financial statements and we are pointing a series of costs and benefitsof their application. To accomplish this work it has been carried out an analysis on the normalization of accounting and particularly on the accounting norms which apply in Romania.Keywords: normalization, regulations, convergence, conformity, standards, accounting

    This paper describes the results from the Integral Fast Reactor (IFR) metallic fuel Run-Beyond-Cladding-Breach (RBCB) experiments conducted in the Experimental Breeder Reactor II (EBR-II). Included in the report are scoping test results and the data collected from the prototypical tests as well as the exam results and discussion from a naturally occurring breach of one of the lead IFR fuel tests. All results showed a characteristic delayed neutron and fission gas release pattern that readily allows for identification and evaluation of cladding breach events. Also, cladding breaches are very small and do not propagate during extensive post breach operation. Loss of fuel from breached cladding was found to be insignificant. The paper will conclude with a brief description of future RBCB experiments planned for irradiation in EBR-II

    Full Text Available There are several factors that affect the company's delay in submitting the financial statements are often referred to as Audit Delay, among others IFRS (International Financial Reporting Standards, firm size, profitability, size public accounting firm, audit opinion, and complexity. One factor that is quite prominent is the application of IFRS that have not been uniform across all companies in Indonesia. It could also lead to Audit Delay. Firm size theoretically means companies bigger scale required to submit financial reports on time. As for profitability, KAP size, and complexity of the audit opinion is also decent enough to be considered as one of the influential factors on Audit Delay. The results of this study indicate that the application of IFRS, profitability, size KAP, audit opinion, and complexity does not have a significant impact on the delay for submission of financial statements. Finaly, a factor that leads to significant effect of time delay submission of financial statements is the size of the company.
