    We present a new determination of the ratio of cross-sections (J/psi) /DY as expected for nucleus-nucleus reactions if J/psi would only be normally absorbed by nuclear matter. This anticipated behaviour is based on proton-nucleus data exclusively, and compared, as a function of centrality, with updated S-U results from experiment NA38 and with the most recent Pb-Pb results from experiment NA50.

    Plant must adapt to changing environmental factors and coordinate their growth and development accordingly. This is accomplished with effective cell communication that includes signaling molecules and receptors to perceive the signal. Plasma membrane proton pumps are key plant proteins...... activation of the pump. Plants exposed to exogenously applied PSY1 showed an increased level of phosphorylated T881 as well as rapid proton efflux from roots. The physiological effect of this proton pump activation was demonstrated to initiate cell elongation. The activation mechanism of PSY1R involved...

  8. $J/\\Psi$ mass shift in nuclear matter

    Gastao Krein, Anthony Thomas, Kazuo Tsushima

    2011-02-01

    The $J/\\Psi$ mass shift in cold nuclear matter is computed using an effective Lagrangian approach. The mass shift is computed by evaluating $D$ and $D^*$ meson loop contributions to the $J/\\Psi$ self-energy employing medium-modified meson masses. The modification of the $D$ and $D^*$ masses in nuclear matter is obtained using the quark-meson coupling model. The loop integrals are regularized with dipole form factors and the sensitivity of the results to the values of form-factor cutoff masses is investigated. The $J/\\Psi$ mass shift arising from the modification of the $D$ and $D^*$ loops at normal nuclear matter density is found to range from $-16$~MeV to $-24$~MeV under a wide variation of values of the cutoff masses. Experimental perspectives for the formation of a bound state of $J/\\Psi$ to a nucleus are investigated.

    PSI1 was identified as a gene that is co-expressed with the phytosulfokine (PSK) receptor genes PSKR1 and PSKR2 in Arabidopsis thaliana. It represents a plant-specific protein family of unknown function with six members in two clades. Clade 1 members PSI1, PSI2 and PSI3 were characterized in this study. All three are nuclear localized. A predicted N-terminal myristoylation site was functionally analyzed. psi1-1 seedlings have shorter roots and hypocotyls. This growth-retarded phenotype was restored by expression of either wildtype PSI1 or PSI1 G2A with a mutated myristate attachment site in the psi1-1 background suggesting that myristate attachment was not essential for PSI1 function. psi2-1 and psi3-1 seedlings have a wildtype phenotype but overexpression of PSI1 or PSI2 promoted seedling growth. PSI2 activity appears to be linked to PSK signaling as psi2-1 and psi2-1 psi3-1 roots are unresponsive to PSK. PSI3 functions in vegetative plant growth synergistic with PSI2. psi3-1 and particularly psi2-1 psi3-1 rosettes are small. Overexpression of PSI3 promoted plant growth indicating that PSI3 is limiting at the vegetative stage. Severe dwarfism of psi2-1 psi3-1 plants results from reduced cell growth and proliferation and premature leaf growth arrest. Plants further display reduced fertility and premature senescence revealing a crucial function of PSI proteins in vegetative growth and reproduction. Psi single and double knock-out plants have less and PSI3ox plants have more starch compared to wt and growth retardation is partially rescued by sucrose. Our studies reveal a crucial function of the nuclear-localized PSI proteins in growth possibly through metabolic control.

    For an effective and efficient management of large amounts of preservice/inservice inspection(PSI/ISI) data in nuclear power plants, an intelligent Windows 95-based data management program was developed. This program enables the prompt extraction of previously conducted PSI/ISI conditions and results so that the time-consuming data management, painstaking data processing and analysis in the past are avoided. The program extracts, and the associated remedies. Furthermore, additional inspection data and comments can be easily added or deleted for subsequent PSI/ISI operation. Although the initial version of the program was applied to Kori nuclear power plant, this program can be equally applied to other nuclear power plant. And also this program can be used to offer the fundamental data for application of evaluation data related to fracture mechanics analysis(FMA), probabilistic reliability assessment(PRA) of PSI/ISI results, performance demonstration initiative(PDI) and risk-informed ISI based on probability of detection(POD) information of ultrasonic examination. Besides, the program can be further developed as a unique PSI/ISI data management expert system that can be apart of PSI/ISI data management expert system that can be a part of PSI/ISI Total Support System(TSS) for Korean nuclear power plants

    The analysis and sizing of detect signal is the most essential in PSI/ISI technique. Ultrasonic testing is the most versatile technique, and the knowledge of ultrsonic attenuation of metal component examined by ultrasonic testing is important to evaluate the signal appeared and to size the flaw of the component. Ultrasonic attenuation measurements were made by using the specimens made of AISI 4140 Carbon Steel with different grain size. Yield strength and ultimate tensile strength were also taken. This report also describes about the principle of multifrequency eddy current test method using two or more operating frequencies simultaneously, and about the simple experiment to read and identify precisely the combined signal caused by more test parameters. It was found that ultrasonic attenuation was increased with increasing grain size and ultrasonic frequency, and yield strength and ultimate tensile strength were decreased with increasing grain size. The results are applicable for ultrasonic testing of carbon steel components as reactor vessel or pressured vessel. The complicated eddy current signal outputs caused by more test parameters and undesirables variables can be identified using multifrequency eddy current test method. It is intended to use multifrequency ECT method for ISI and PSI of steam generator tubes from 1985. (Author)

    Cold nuclear matter effects on J/{psi} production in proton-nucleus and nucleus-nucleus collisions are evaluated taking into account the specific J/{psi}-production kinematics at the partonic level, the shadowing of the initial parton distributions and the absorption in the nuclear matter. We consider two different parton processes for the c{bar c}-pair production: one with collinear gluons and a recoiling gluon in the final state and the other with initial gluons carrying intrinsic transverse momentum. Our results are compared to RHIC observables. The smaller values of the nuclear modification factor R{sub AA} in the forward rapidity region (with respect to the mid rapidity region) are partially explained, therefore potentially reducing the need for recombination effects.

    An intelligent database program has been developed under fully compatible with windows 95 for the construction of total support system and the effective management of Pre-/In-Service Inspection data. Using the database program, it can be executed the analysis and multi-dimensional evaluation of the defects detected during PSI/ISI in the pipe and the pressure vessel of the nuclear power plants. And also it can be used to investigate the NDE data inspected repetitively and the contents of treatment, and to offer the fundamental data for application of evaluation data related to Fracture Mechanics Analysis(FMA). Furthermore, the PSI/ISI database loads and material properties can be utilized to secure the higher degree of safety, integrity, reliability, and life-prediction of components and systems in nuclear power plant.

    The department 'Nuclear Energy and Safety Research' (F4) at PSI carries the responsibility of performing the essential nuclear energy research in Switzerland. This research is part of the remit of PSI and follows government directive; about one-fifth of the Institute's Federal budget is allocated to this task. Currently about 190 persons are working in this field. Approximately 45% of the salary and investment costs (5.5 million CHF in the budget period 1996/97) are externally funded. This funding is provided primarily by the Swiss Utilities, the NAGRA and the safety authority HSK. The activities in nuclear research concentrate on three main domains: safety and safety related problems of operating plants, safety features of future reactor and fuel cycle concepts and waste management; another 4% of staff are addressing broader aspects of energy. At the end of 1996, a policy evaluation with the laboratory heads took place in order to redefine the direction of F4 activities. (author) figs., tabs., refs

    Highlights: • The PSI air oxidation model has been successfully implemented in MELCOR. • The model treats oxygen as an active species and nitrogen as a catalyst. • The implementation has been assessed against the previous post-test analyses for QUENCH-16. • The pre-oxidation and air phase were consistent when similar modelling options were used. • All code versions were in fair agreement with the experimental data. - Abstract: The PSI air oxidation model has been successfully implemented in the lump parameter code MELCOR. The PSI air oxidation model treats oxygen as an active species and nitrogen as a catalyst that accelerates the oxidation kinetics. The essential feature of the model is the transition from parabolic to linear kinetics. The implementation has been assessed against the previous post-test analyses for the air ingress experiment QUENCH-16 performed with a local version of RELAP5/SCDAPSim3.5. This version contains the PSI air oxidation model. The pre-oxidation and air phase were consistent when similar modelling options were used and all code versions were in fair agreement with the experimental data, showing consistency in the implementation of the model. The PSI air oxidation model will be used in the future for analysis of spent fuel pool uncovery sequences where steam/air mixture is the prototypical environment

    We present a wide study on the comparison of different shadowing models and their influence on J/{psi} production. We have taken into account the possibility of different partonic processes for the c{bar c}-pair production. We notice that the effect of shadowing corrections on J/{psi} production clearly depends on the partonic process considered. Our results are compared to the available data on dAu collisions at RHIC energies. We try different break up cross section for each of the studied shadowing models.

    From research activities focused on civil and military uses of nuclear energy and developed after the second world war, the Paul Scherrer Institute (PSI) has been able to diversify its activities following 2 axis. First, the Gantry proton-therapy that is characterized by a compact equipment and an accurate 3-dimensional treatment of tumors (more than 260 patients have been treated by Gantry from 1996 to 2005). Secondly, new technologies in the fields of energy and transport. Nevertheless, PSI has been able to keep a high of valuation of its staff in nuclear engineering and materials that are the core of its activities. The main equipment of PSI are: -) SLS (Swiss Light Source): a synchrotron radiation source that is both a microscope and an X-ray source; -) SINQ: a neutron source based on spallation reactions; -)SμS: a muon source; and -) the Philips accelerator that is used in radiochemistry and the production of isotopes used for the treatment of eye tumors. PSI has established a large cooperation with French research laboratories on issues like: nuclear reactor safety, synchrotron radiation, the transmutation of nuclear wastes, the design of a source of ultra-cold neutrons, or the development of a hydrogen-fueled light vehicle. The total budget of PSI for 2007 reached 174.2 million euros. (A.C.)

  12. The Air Blast Wave from a Nuclear Explosion

    Science.gov (United States)

    Reines, Frederick

    The sudden, large scale release of energy in the explosion of a nuclear bomb in air gives rise, in addition to nuclear emanations such as neutrons and gamma rays, to an extremely hot, rapidly expanding mass of air.** The rapidly expanding air mass has an initial temperature in the vicinity of a few hundred thousand degrees and for this reason it glows in its early stages with an intensity of many suns. It is important that the energy density in this initial "ball of fire" is of the order of 3 × 103 times that found in a detonating piece of TNT and hence that the initial stages of the large scale air motion produced by a nuclear explosion has no counterpart in an ordinary. H. E. explosion. Further, the relatively low temperatures ˜2,000°C associated with the initial stages of an H. E. detonation implies that the thermal radiation which it emits is a relatively insignificant fraction of the total energy involves. This point is made more striking when it is remembered that the thermal energy emitted by a hot object varies directly with the temperature in the Rayleigh Jeans region appropriate to the present discussion. The expansion of the air mass heated by the nuclear reaction produces, in qualitatively the same manner as in an H.E. explosion or the bursting of a high pressure balloon, an intense sharp pressure pulse, a shock wave, in the atmosphere. As the pressure pulse spreads outward it weakens due to the combined effects of divergence and the thermodynamically irreversible nature of the shock wave. The air comprising such a pressure pulse or blast wave moves first radially outward and then back towards the center as the blast wave passes. Since a permanent outward displacement of an infinite mass of air would require unlimited energy, the net outward displacement of the air distant from an explosion must approach zero with increasing distance. As the distance from the explosion is diminished the net outward displacement due to irreversible shock heating of

    Inclusive J/$\\psi$ production has been studied with the ALICE detector in p-Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV at the CERN LHC, in the rapidity domains 2.03 < y$_{cms}$ < 3.53 and −4.46 < y$_{cms}$ < −2.96, down to zero transverse momentum. The J/$\\psi$ measurement is performed in the Muon Spectrometer through the $\\mu^+\\mu^−$ decay mode. In this Letter, the J/$\\psi$ production cross section and the nuclear modification factor R$_{pPb}$ for the rapidities under study are presented. While at forward rapidity a suppression of the J/$\\psi$ yield with respect to binary-scaled pp collisions is observed, in the backward region no suppression is present. The ratio of the forward and backward yields is also shown differentially in rapidity and transverse momentum. Theoretical predictions based on nuclear shadowing, as well as on models including, in addition, a contribution from partonic energy loss, are in fair agreement with the experimental results.

  14. Structural dynamic and resistance to nuclear air blast

    International Nuclear Information System (INIS)

    Qureshi, S.M.

    2003-01-01

    A need exists to design protective shelters attached to specialized facilities against nuclear airbursts, explosive shocks and impacting projectiles. Designing such structures against nuclear and missile impact is a challenging task that needs to be looked into for design methodology formulation and practicability. Structures can be designed for overpressure pulsed generated by a nuclear explosion as well as the scabbing and perforation/punching of an impacting projectile. This paper discuses and formulates the methods of dynamic analysis and design required to undertake such a task. Structural resistance to peak overpressure pulse for a 20 KT weapons and smaller tactical nuclear weapons of 1 KT (16 psi, overpressure) size as a direct air blast overpressure has been considered in design of walls, beams and slabs of a special structure under review. The design of shear reinforcement as lacing is also carried out. Adopting the philosophy of strengthening and hardening can minimize the effect of air blast overpressure and projectile impact. The objective is to avoid a major structural failure. The structure then needs to be checked against ballistic penetration by a range of weapons or be required to resist explosive penetration from the charge detonated in contact with the structure. There is also a dire need to formulate protective guidelines for all existing and future critical facilities. (author)

  15. J/psi production in proton-nucleus collisions at ALICE: cold nuclear matter really matters

    CERN Multimedia

    CERN. Geneva

    2013-01-01

    Heavy quarkonia are expected to be sensitive to the properties of strongly interacting matter, at both low and high temperatures. In nucleus-nucleus collisions, a phase transition to a deconfined state of quarks and gluons (Quark-Gluon Plasma) is thought to take place once the temperature of the system exceeds a critical temperature of the order of 150-200 MeV. The deconfined state can induce a suppression of charmonium (due to color screening, dominant at SPS and RHIC energies), which can be overturned at LHC energy by the (re)combination of the large number of free c and cbar quarks, taking place when the system cools down below the critical temperature. Cold nuclear matter also has an influence on heavy quarkonia. Such effects can be studied in proton-nucleus collisions, where no deconfined state is expected to be created. At LHC energy, they mainly include nuclear shadowing, gluon saturation, break-up of the quarkonium states, and parton energy loss in the initial and final state. The study of these eff...

    From research activities focused on civil and military uses of nuclear energy and developed after the second world war, the Paul Scherrer Institute (PSI) has been able to diversify its activities following 2 axis. First, the Gantry proton-therapy that is characterized by a compact equipment and an accurate 3-dimensional treatment of tumors (more than 260 patients have been treated by Gantry from 1996 to 2005). Secondly, new technologies in the fields of energy and transport. Nevertheless, PSI has been able to keep a high of valuation of its staff in nuclear engineering and materials that are the core of its activities. The main equipment of PSI are: -) SLS (Swiss Light Source): a synchrotron radiation source that is both a microscope and an X-ray source; -) SINQ: a neutron source based on spallation reactions; -)S{mu}S: a muon source; and -) the Philips accelerator that is used in radiochemistry and the production of isotopes used for the treatment of eye tumors. PSI has established a large cooperation with French research laboratories on issues like: nuclear reactor safety, synchrotron radiation, the transmutation of nuclear wastes, the design of a source of ultra-cold neutrons, or the development of a hydrogen-fueled light vehicle. The total budget of PSI for 2007 reached 174.2 million euros. (A.C.)

    Selected highlights in this years report include muon spin studies and investigations of polymer films, the chemical properties of element 112 and the antitumour effects of radionuclides. In its fifth year of operation, results from the SLS include shedding light on superconductivity and understanding magnetism at the nanoscale. From the energy research departments we hear that progress has been achieved in the conversion of biomass to methane fuel, and towards the generation of hydrogen by solar thermochemistry. Combustion research, among other themes, focused on efficiency in gas turbine processes. Neutronic studies dealt with safety aspects of present nuclear reactors, thermal hydraulics with reactors of the future. safety is also the issue in how ions migrate in waste repositories or in the operation of the MEGAPIE liquid metal target. The Competence Center Energy and Mobility of the ETH domain, for which PSI acts as he facilitator, started operation at the beginning of 2006, and several projects have been successfully launched. The reports in this volume are only a fraction of the varied research undertaken at PSI in the past year; for more information visit our website www.psi.ch. (author)

    We observe psi (3684) to decay into psi (3095) with a branching ratio of 0.57plus-or-minus0.08. The branching ratio for the particular decay mode psi (3095)+π + +π - is measured to be 0.32plus-or-minus0.04. Remaining decays leading to psi (3095) are largely, but not entirely, accounted for by the mode psi (3095)+π 0 +π 0 if the two pions in this decay are in a state of zero isospin

  10. Guidance for air sampling at nuclear facilities

    1976-11-01

    The principal uses of air sampling at nuclear facilities are to monitor general levels of radioactive air contamination, identify sources of air contamination, and evaluate the effectiveness of contaminant control equipment, determine exposures of individual workers, and provide automatic warning of hazardous concentrations of radioactivity. These applications of air sampling are discussed with respect to standards of occupational exposure, instrumentation, sample analysis, sampling protocol, and statistical treatment of concentration data. Emphasis is given to the influence of spacial and temporal variations of radionuclide concentration on the location, duration, and frequency of air sampling

    Nuclear techniques have important applications in the study of air pollution and many of its components. However, it is in the study of airborne particulate matter (APM) that nuclear analytical techniques find many of their most important applications. This article focuses on those applications, and on the work of the IAEA in this important field of study. 2 figs

    Most of the nuclear energy research carried out in Switzerland takes place in the research department of the same name at the Paul Scherrer Institut. The year 1992 was characterized by the commissioning of new experimental facilities and the realization of new projects, which have been conceived over the past few years. Along with work in the traditional fields of safety (including safety-related operational fields) of nuclear power plants, disposal of radioactive waste, and safety features of future reactor concepts, a new, interdisciplinary project for the global assessment of energy systems (with regard to safety, economics, and environmental impact) was initiated together with the General Energy Research Department of PSI and with ETH in Zuerich.

  13. Air filters for use at nuclear facilities

    Energy Technology Data Exchange (ETDEWEB)

    Linder, P [Aktiebolaget Atomenergi, Studsvik, Nykoeping (Sweden)

    1970-12-01

    The ventilation system of a nuclear facility plays a vital role in ensuring that the air in working areas and the environment remains free from radioactive contamination. An earlier IAEA publication, Techniques for Controlling Air Pollution from the Operation of Nuclear Facilities, Safety Series No. 17, deals with the design and operation of ventilation systems at nuclear facilities. These systems are usually provided with air-cleaning devices which remove the contaminants from the air. This publication is intended as a guide to those who are concerned with the design of air-filtering systems and with the testing, operation and maintenance of air-filter installations at nuclear facilities. Emphasis is mainly placed on so-called high-efficiency particulate air filters (HEPA filters) and on providing general information on them. Besides describing the usual filter types, their dimensions and construction materials, the guidebook attempts to explain their properties and behaviour under different operating conditions. It also gives advice on testing and handling the filters so that effective and safe performance is ensured. The guidebook should serve as an introduction to the use of high efficiency particulate air filters in countries where work with radioactive materials has only recently commenced. The list of references at the end of the book indicates sources of more advanced information for those who already have comprehensive experience in this field. It is assumed here that the filters are obtained from a manufacturer, and the guidebook thus contains no information on the design and development of the filter itself, nor does it deal with the cleaning of the intake air to a plant, with gas sorption or protective respiratory equipment.

    We have studied the transverse-momentum ($p_{\\rm T}$) dependence of the inclusive J/$\\psi$ production in p-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV, in three center-of-mass rapidity ($y_{\\rm cms}$) regions, down to zero $p_{\\rm T}$. Results in the forward and backward rapidity ranges ($2.03 < y_{\\rm cms} < 3.53$ and $-4.46 < y_{\\rm cms} < -2.96$) are obtained by studying the J/$\\psi$ decay to $\\mu^+\\mu^-$, while the mid-rapidity region ($-1.37 < y_{\\rm cms} < 0.43$) is investigated by measuring the ${\\rm e}^+{\\rm e}^-$ decay channel. The $p_{\\rm T}$ dependence of the J/$\\psi$ production cross section and nuclear modification factor are presented for each of the rapidity intervals, as well as the J/$\\psi$ mean $p_{\\rm T}$ values. Forward and mid-rapidity results show a suppression of the J/$\\psi$ yield, with respect to pp collisions, which decreases with increasing $p_{\\rm T}$. At backward rapidity no significant J/$\\psi$ suppression is observed. Theoretical models including a combinat...

  17. Continuing challenges in nuclear air cleaning

    The safe operation of nuclear facilities is heavily dependent upon the adequate performance of air cleaning systems. Although many problems have been solved, new questions and new challenges continue to arise. These are well illustrated by weaknesses in air cleaning and ventilating systems revealed by the Browns Ferry fire, and the need to develop additional data on the reliability of such systems, particularly under emergency conditions, as revealed by the Reactor Safety Study. Assessments of the degree to which engineered safety features can compensate for deficiencies in nuclear power plant sites continue to challenge those involved in risk/benefit evaluations. Additional challenges are being generated by the air cleaning requirements associated with the commercial development of the liquid metal fast breeder reactor

    A measurement of beauty hadron production at mid-rapidity in proton-lead collisions at a nucleon-nucleon centre-of-mass energy $\\sqrt{s_{\\rm NN}} = 5.02$ TeV is presented. The semi-inclusive decay channel of beauty hadrons into J/$\\psi$ is considered, where the J/$\\psi$ mesons are reconstructed in the dielectron decay channel at mid-rapidity down to transverse momenta of 1.3 GeV/$c$. The b$\\rm{\\overline b}$ production cross section at mid-rapidity, ${\\rm d}\\sigma_{\\rm{b\\overline b}}/{\\rm d}y$ , and the total cross section extrapolated over full phase space, $\\sigma_{\\rm{b\\overline b}}$, are obtained. This measurement is combined with results on inclusive J/$\\psi$ production to determine the prompt J/$\\psi$ cross sections. The results in p-Pb collisions are then scaled to expectations from pp collisions at the same centre-of-mass energy to derive the nuclear modification factor $R_{\\rm pPb}$, and compared to models to study possible nuclear modifications of the production induced by cold nuclear matter effects...

    The production of $J/\\psi$ mesons with rapidity 1.5 < $y$ < 4.0 or -5.0 < $y$ <-2.5 and transverse momentum $p_\\mathrm{T}$ < 14 GeV/$c$ is studied with the LHCb detector in proton-lead collisions at a proton-nucleon centre-of-mass energy $\\sqrt{s_{NN}}=5~\\mathrm{TeV}$. The J/ψ mesons are reconstructed using the dimuon decay mode. The analysis is based on a data sample corresponding to an integrated luminosity of about 1.6 nb$^{−1}$. For the first time the nuclear modification factor and forward-backward production ratio are determined separately for prompt J/ψ mesons and J/ψ from b-hadron decays. Clear suppression of prompt J/ψ production with respect to proton-proton collisions at large rapidity is observed, while the production of J/ψ from b-hadron decays is less suppressed. These results show good agreement with available theoretical predictions. The measurement shows that cold nuclear matter effects are important for interpretations of the related quark-gluon plasma signatures in he...

    We have carried out a wide study of Cold Nuclear Matter (CNM) effects on J/{Psi} = production in dAu, CuCu and AuAu collisions at {radical}s{sub NN} = 200 GeV. We have studied the effects of three different gluon-shadowing parameterizations, using the usual simplified kinematics for which the momentum of the gluon recoiling against the J/{Psi} is neglected as well as an exact kinematics for a 2 {yields} 2 process, namely g + g {yields} J/{psi} + g as expected from LO pQCD. We have shown that the rapidity distribution of the nuclear modification factor R{sub dAu}, and particularly its anti-shadowing peak, is systematically shifted toward larger rapidities in the 2 {yields} 2 kinematics, irrespective of which shadowing parameterization is used. In turn, we have noted differences in the effective final-state nuclear absorption needed to fit the PHENIX dAu data. Taking advantage of our implementation of a 2 {yields} 2 kinematics, we have also computed the transverse momentum dependence of the nuclear modification factor, which cannot be predicted with the usual simplified kinematics. All the corresponding observables have been computed for CuCu and AuAu collisions and compared to the PHENIX and STAR data. Finally, we have extracted the effective nuclear absorption from the recent measurements of RCP in dAu collisions by the PHENIX collaboration.

  3. Nuclear air cleaning activities in Germany

    Wilhelm, J.

    1991-01-01

    The discussion is limited to nuclear air cleaning activities in the Federal Republic of Germany. Work is underway on containment venting with regard to filtration based on a combination of stainless steel roughing and fine filters with a decontamination factor similar to or better than that achieved with high-efficiency particulate air filters. The main point of interest is the development of relatively small filter units that can be located inside the containment. The concept of a new design for double containment having annular rooms between the steel containment and the concrete containment is discussed. Work related to the dismantling of decommissioned reactors and limited research for fuel reprocessing facilities are also noted

  4. Rare psi decays

    International Nuclear Information System (INIS)

    Partridge, R.

    1986-01-01

    Slightly more than ten years have passed since the psi was discovered, yet the study of psi decays continues to be an active and fruitful area of research. One reason for such longevity is that each successive experiment has increased their sensitivity over previous experiments either by improving detection efficiency or by increasing statistics. This has allowed the observation and, in some cases, detailed studies of rare psi decays. Branching ratios of ≅10-/sup 4/ are now routinely studied, while certain decay channels are beginning to show interesting effects at the 10-/sup 5/ level. Future experiments at the Beijing Electron Positron Collider (BEPC) have the potential for increasing sensitivities by one or two orders of magnitude, thus enabling many interesting studies impossible with current data samples. The author first examines the extent to which psi decays can be used to study electroweak phenomena. The remainder of this work is devoted to the more traditional task of using the psi to study quarks, gluons, and the properties of the strong interaction. Of particular interest is the study of radioactive psi decays, where a number of new particles have been discovered. Recent results regarding two of these particles, the θ(1700) and iota(1450), are discussed, as well as a study of the quark content of the eta and eta' using decays of the psi to vector-pseudoscalar final states

    A survey of the types and frequency of ligands that are bound to PSI structures is analyzed as well as their utility in functional annotation of previously uncharacterized proteins. Approximately 65% of PSI structures report some type of ligand(s) that is bound in the crystal structure. Here, a description is given of how such ligands are handled and analyzed at the JCSG and a survey of the types, variety and frequency of ligands that are observed in the PSI structures is also compiled and analyzed, including illustrations of how these bound ligands have provided functional clues for annotation of proteins with little or no previous experimental characterization. Furthermore, a web server was developed as a tool to mine and analyze the PSI structures for bound ligands and other identifying features

    Standardization in nuclear air and gas treatment spans a period of more than 25 years, starting with military specifications for HEPA filters and filter media, and now progressing to the development of a formal code analogous to the ASME Boiler and Pressure Vessel Code. Whereas the current standard for components and installation of nuclear air cleaning systems is limited to safety related facilities for nuclear power plants, the proposed code will cover all types of critical ventilation and air and gas treatment installations for all types of nuclear facilities

    Effective operation techniques were reviewed on the air treatment system to protect the personnel in nuclear facilities from the contamination of radio-active particles and to keep the environment clear. Nuclear air treatment system consisted of the ventilation and filtering system was characterized by some test. Measurement of air velocity of blowing/exhaust fan in the ventilation system, leak tests of HEPA filters in the filtering, and measurement of pressure difference between the areas defined by radiation level were conducted. The results acquired form the measurements were reflected directly for the operation of air treatment. In the abnormal state of virus parts of devices composted of the system, the repairing method, maintenance and performance test were also employed in operating effectively the air treatment system. These measuring results and techniques can be available to the operation of air treatment system of PIEF as well as the other nuclear facilities in KAERI.

    This invention concerns a ventilation-air conditioner system which enables, upon occurrence of accidents in a nuclear power plant, continuous operation for other adjacent nuclear power plants with no effect of accidents. Air supply system and exhaust system are operated during usual operaiton. If loss of coolants accidents should occur in an adjacent nuclear power plants, operation is switched from ventilation operaiton to the operation of re-cycling system based on an AND logic of three signals, that is, a pressure HIGH signal for the reactor container, a water level LOW signal for the reactor and a radioactivity signal of the ventilation-air conditioner sytem on the side of air supply in the nuclear power plant. Thus, nuclear reactor buildings of the nuclear power plant are from the external atmosphere. Therefore, the radioactivity HIGH signal for switching to the emergency air conditioner system of the nuclear power plant is not actuated due to the loss of coolant accidents in the adjacent nuclear power plant. In addition, since the atmospheric temperature in the nuclear reactor building can be maintained by a cooling device disposed to the recycling system, reactor shutdown can be prevented. (I.S.)

    The ALICE Collaboration has studied inclusive J/$\\psi$ and $\\psi$(2S) production in p-Pb collisions at $\\sqrt{s_{\\rm NN}} = 5.02$ TeV with the Muon Spectrometer. The measurement was performed at forward (2.03 $<$ $y_{\\rm cms}$ $<$ 3.53) and backward ($-$4.46 $<$ $y_{\\rm cms}$ $<$ $-$2.96) centre of mass rapidities. The nuclear modification factor of J/$\\psi$ and $\\psi$(2S) has been measured as a function of transverse momentum and event activity. Theoretical models based on nuclear shadowing, coherent energy loss or both are in reasonable agreement with the J/$\\psi$ results but cannot describe the $\\psi$(2S) behaviour. Other mechanisms must be invoked in order to explain the $\\psi$(2S) suppression in p-Pb collisions.

    Interactions of 209-GeV muons within an instrumented magnetized-steel calorimeter have produced 4374 +- 87 ..mu../sup +/..mu../sup -/ pairs from J/psi decay, corresponding to the cross section sigma(..mu..N ..-->.. ..mu.. psi X) = 0.64 +- 0.10 nb. These interactions are classified as either elastic (sigma = 0.36 +- 0.07 nb) or inelastic (sigma = 0.28 +- 0.06 nb) based primarily on the calorimetric determination of E/sub X/. The cross section for elastic psi production by virtual photons, sigma/sub eff/(..gamma../sub V/N), rises with energy nu as log nu. Its dependence on Q/sup 2/ fits the vector-meson dominance form P(..lambda..) = (1 + Q/sup 2//..lambda../sup 2/)/sup -2/, with ..lambda.. = (2.0 - 2.4) +- 0.15 GeV, where the spread in values arises from considering the possibility of a Q/sup 2/ dependence in the decay angular distribution W (theta,phi) and in the nuclear shadowing factor.

    Interactions of 209-GeV muons within an instrumented magnetized-steel calorimeter have produced 4374 +- 87 μ + μ - pairs from J/psi decay, corresponding to the cross section sigma(μN → μ psi X) = 0.64 +- 0.10 nb. These interactions are classified as either elastic (sigma = 0.36 +- 0.07 nb) or inelastic (sigma = 0.28 +- 0.06 nb) based primarily on the calorimetric determination of E/sub X/. The cross section for elastic psi production by virtual photons, sigma/sub eff/(γ/sub V/N), rises with energy nu as log nu. Its dependence on Q 2 fits the vector-meson dominance form P(Λ) = (1 + Q 2 /Λ 2 ) -2 , with Λ = (2.0 - 2.4) +- 0.15 GeV, where the spread in values arises from considering the possibility of a Q 2 dependence in the decay angular distribution W (theta,phi) and in the nuclear shadowing factor. We find that W(theta,phi) is consistent with the form expected if the reaction γ/sub V/N → psiN conserves helicity in the s channel through natural-parity exchange in the t channel.

    The Crystal Ball detector at SPEAR has been used to investigate the decays psi'→etaJ/psi and psi'→π 0 J/psi resulting from production of 776 000 psi'. Our measurement for the branching ratio of the eta mode is (2.18 +- 0.14 +- 0.35)%, where the first error results from statistics and acceptance uncertainties, and the second error is systematic; this is almost a factor of 2 smaller than found in early experiments. For the isospin-nonconserving π 0 mode, a branching ratio (0.09 +- 0.02 +- 0.01)% is obtained

  19. J/psi production in pp collisions from ALICE

    CERN Multimedia

    CERN. Geneva

    2012-01-01

    The ALICE experiment studied J/psi production in the mu+mu- and e+e- decay channels. Inclusive cross sections were measured at both forward and central rapidity down to zero transverse momentum. The results are compared with NRQCD calculations and, for the pp sample collected at sqrt(s)=2.76 TeV, are used as a reference for the determination of nuclear effects on J/psi production in Pb-Pb. At central rapidity, the fraction of J/psi coming from B-decays has been evaluated down to p_T=1.3 GeV/c. In addition, the J/psi yield has been found to linearly increase as a function of the charged hadron multiplicity produced in the collision. Finally, the first LHC results on J/psi polarization, an essential observable for the understanding of the production mechanisms and for theory comparisons, will be presented.

    Certified Reference Materials (hereafter called as to CRMs), which are indispensable for Quality Assurance and Material Accountability in nuclear fuel plants, are being provided by overseas suppliers to Japanese nuclear entities as Type A package (non-fissile) through air transport. However, after the criticality accident at JCO in Japan, special law defining nuclear disaster countermeasures (hereafter called as to the LAW) has been newly enforced in June 2000. Thereafter, nuclear fuel materials must meet not only to the existing transport regulations but also to the LAW for its transport

    Air is an important environmental component in human life. Presence of air pollutants or contaminants will have a negative impact on human health. According to the existence of a nuclear facility in Yogyakarta, the characterization of radionuclides in the air is absolutely necessary to ensure the safety of people and the environment and also to supervise the safe operation of the facility. In this research the characterization of radionuclides in the air was carried through the air sampling by using High Volume Air Sampler equipped with filter TFA 2133, followed by analysis using combination of a gamma and alpha spectrometers. The concentration of radioactivity in the air fluctuates depending on the time and duration of sampling. Characterization of gamma emitting radionuclides in the air is dominated by radon progeny radionuclides such as 214 Pb, 214 Bi with activity 20.09 ± 1.23 until 32.91 ± 4.87 Bq/m 3 and 31.22 ± 1.76 until 44.25 ± 4.91 Bq/m 3 . Alpha emitter radionuclide was dominated by 214 Po (7.69 MeV) which is also radon progeny and a primordial radionuclides. It can be concluded that the presence of radionuclides in the environmental air not as a product resulting from the operation of nuclear facilities in Yogyakarta. (author)

    The report at hand renders an account of the first year of PSI, which arose from the fusion of EIR and SIN, at the beginning of 1988. The since then more wide-spread field of activity makes a new form for the annual report necessary, because - specially in the case of the SIN reports - a relatively detailed, scientifically technical presentation would be too extensive and not of interest to all its readers. Therefore, a shorter and generally comprehensive report on the activities in each area of research - abridged by relevant information of administrative nature about the institute, is given. Additionally, each of the five areas of research are to submit, in leisurely sequence, a newsletter addressed to professionals. 64 figs., 7 tabs

    uv mutagenesis was used to probe the molecular nature of [psi], a nonmitochondrial cytoplasmic determinant of Saccharomyces cerevisiae involved in the control of nonsense suppression. The uv-induced mutation from [psi + ] to [psi - ] showed characteristics of forward nuclear gene mutation in terms of frequency, induction kinetics, occurrence of whole and sectored mutant clones and the effect of the stage in the growth cycle on mutation frequency. The involvement of pyrimidine dimers in the premutational lesion giving the [psi - ] mutation was demonstrated by photoreactivation. uv-induced damage to the [psi] genetic determinant was shown to be repaired by nuclear-coded repair enzymes that are responsible for the repair of nuclear DNA damage. uv-induced damage to mitochondrial DNA appeared to be, at least partly, under the control of different repair processes. The evidence obtained suggests that the [psi] determinant is DNA

    The Space Nuclear Thermal Propulsion (SNTP) Program is an initiative within the US Air Force to acquire and validate advanced technologies that could be used to sustain superior capabilities in the area or space nuclear propulsion. The SNTP Program has a specific objective of demonstrating the feasibility of the particle bed reactor (PBR) concept. The term PIPET refers to a project within the SNTP Program responsible for the design, development, construction, and operation of a test reactor facility, including all support systems, that is intended to resolve program technology issues and test goals. A nuclear test facility has been designed that meets SNTP Facility requirements. The design approach taken to meet SNTP requirements has resulted in a nuclear test facility that should encompass a wide range of nuclear thermal propulsion (NTP) test requirements that may be generated within other programs. The SNTP PIPET project is actively working with DOE and NASA to assess this possibility.

  11. Air and gas cleaning technology for nuclear applications

    International Nuclear Information System (INIS)

    First, M.W.

    1986-01-01

    All large-scale uses of radioactive materials require rigid control of off-gases and generated aerosols. Nuclear air and gas cleaning technology has answered the need from the days of the Manhattan Project to the present with a variety of devices. The one with the longest and most noteworthy service is the HEPA (high efficiency particulate air) filter that originally was referred to as an absolute filter in recognition of its extraordinary particle retention characteristics. Activated-charcoal adsorbers have been employed worldwide for retention of volatile radioiodine in molecular and combined forms and, less frequently, for retention of radioactive noble gases. HEPA filters and activated -charcoal adsorbers are often used with auxiliary devices that serve to extend their effective service life or significantly improve collection efficiency under unfavorable operating conditions. Use of both air cleaning devices and their auxiliaries figure prominently in atomic energy, disposal of high- and low-level nuclear wastes, and in the production of fissile materials. The peaceful uses of nuclear energy would be impossible without these, or equivalent, air- and gas-cleaning devices

  12. The ''Nuclear-Karlsruhe'' air-filter system

    International Nuclear Information System (INIS)

    Berliner, P.; Ohlmeyer, M.; Stotz, W.

    1976-01-01

    Increasing requirements for exhaust-air filter systems used in nuclear facilities induced the Gesellschaft fuer Kernforschung to develop the ''Nuclear-Karlsruhe'' HEPA filter system. This novel development has profited by experience gained in previous incidents as well as by maitenance and decontamination work performed with different HEPA filter systems. The proved ''Nuclear-Karlsruhe'' system takes equally into account the demands for optimum safety, maximum efficiency and economy, and is distinguished by the following features: (1) The air current is defected by 180 0 in the casing. Deflection causes quite a number of improvements, results in substantial reduction of space requirements, and avoids the dispersion of pollutants to the clean-air side. Besides, the HEPA filter is protected from damage by condensed particles or foreign materials entrained; (2) The ''Nuclear-Karlsruhe'' system allows gas-tight filter replacement. Special replacement collars have been provided at the casing, which allow the tight fastening of replacement bags which are self-locking. (3) In-place testing in the operating condition can be carried out very conveniently because the air is deflected. Minimum leaks in the filter medium or in the filter gasket can be detected by the high-sensitivity visual oil-thread test, which makes leaks distinctly visible as oil mist threads through a transparent front window provided on the clean-air side. The test takes only some minutes and its sensitivity is hardly matched by any other technique. (4) The clamping mechanism is installed outside the casing, i.e. outside the polluted or aggressive media. The contact force is spring-loaded absolutely uniformly to the circular filter gasket. (5) For practical and econmic reasons the filter casings can be locked individually so as to be gas-tight. (6) The entire system is made of stainless or coated steel and metal parts which are corrosion and fire-resistant. (author)

    Disclosed is an air box type shock absorber primarily for use in an ice condenser compartment of a nuclear reactor. The shock absorber includes a back plate member and sheet metal top, bottom, and front members. The front member is prefolded, and controlled clearances are provided among the members for predetermined escape of air under impact and compression. Prefolded internal sheet metal stiffeners also absorb a portion of the kinetic energy imparted to the shock absorber, and limit rebound. An external restraining rod guided by restraining straps insures that the sheet metal front member compresses inward upon impact. 6 claims, 11 figures

    The most recent results obtained by experiment NA50 show that the $J /\\psi$ cross-section per nucleon-nucleon collision in semi-peripheral Pb-Pb reactions is "normally" suppressed in the sense that it follows the trend already observed from p-p and up to the most central S-U reactions. A clear change of behaviour is observed for more central Pb-Pb collisions which could be due to the transition of normal nuclear matter to its predicted Quark-Gluon Plasma state

    The nuclear industry now has over 35 years of experience in nuclear air cleaning. This experience covers technology development, system design, operations, and maintenance. Much of the past experience has been directed towards technology development with particular emphasis on high efficiency particulate air (HEPA) filters. Implementation of this technology has lagged its development by a number of years. A recent study examines the cause and frequencies of HEPA filter changeouts and failures. These data lead to a conclusion that a shift in emphasis from technology development to the training of personnel and the designing and maintaining of such systems is needed. Some highlights of the data and a discussion of topics which should be addressed in training will be presented

    -coupled extrapolation to a multi-scale, coupled approach. The PSI Plasma Center consisted of three equal co-centers; one located at the MIT Plasma Science and Fusion Center, one at UC San Diego Center for Energy Research and one at the UC Berkeley Department of Nuclear Engineering, which moved to the University of Tennessee, Knoxville (UTK) with Professor Brian Wirth in July 2010. The Center had three co-directors: Prof. Dennis Whyte led the MIT co-center, the UCSD co-center was led by Dr. Russell Doerner, and Prof. Brian Wirth led the UCB/UTK center. The directors have extensive experience in PSI and material research, and have been internationally recognized in the magnetic fusion, materials and plasma research fields. The co-centers feature keystone PSI experimental and modeling facilities dedicated to PSI science: the DIONISOS/CLASS facility at MIT, the PISCES facility at UCSD, and the state-of-the-art numerical modeling capabilities at UCB/UTK. A collaborative partner in the center is Sandia National Laboratory at Livermore (SNL/CA), which has extensive capabilities with low energy ion beams and surface diagnostics, as well as supporting plasma facilities, including the Tritium Plasma Experiment, all of which significantly augment the Center. Interpretive, continuum material models are available through SNL/CA, UCSD and MIT. The participating institutions of MIT, UCSD, UCB/UTK, SNL/CA and LLNL brought a formidable array of experimental tools and personnel abilities into the PSI Plasma Center. Our work has focused on modeling activities associated with plasma surface interactions that are involved in effects of He and H plasma bombardment on tungsten surfaces. This involved performing computational material modeling of the surface evolution during plasma bombardment using molecular dynamics modeling. The principal outcomes of the research efforts within the combined experimental – modeling PSI center are to provide a knowledgebase of the mechanisms of surface degradation, and the

    Even as separate institutes, the EIR (Eidg. Institut fuer Reaktorforschung and the SIN (Schweiz. Institut fuer Nuklearforschung) made use of ionizing radiation and radioactivity in medical diagnosis and therapy. After their fusion into a national laboratory, the Paul Scherrer Institute (PSI), these projects were combined with those of the Radiation Protection Group and the Life Sciences Department was formed. In equality with the departments of Nuclear and Particle Physics, Condensed Matter and Materials Sciences, and Energy Research and Engineering Sciences, the department of Life Sciences is one of the major pillars of the new center. The activities are divided into three areas: radiation medicine, radiopharmacy, and radiation protection. The goal of the first two is to develop social and economic uses of radioactivity and elementary particles. The Division of Radiation Medicine proposes to achieve this through the development of original, dynamic and conformal tumor therapy with charged particles and the Division of Radiopharmacy through the investigation into, and the production of, highly specific diagnostic systems for SPECT, PET and MRI and the investigation of the use of radionuclides in therapy. The third division, Radiation Protection, evaluates the risks of ionizing radiation in biology and the ecosphere and proposes adequate protection measures. The present report describes, in the first section, the outstanding scientific results of the past year and, in the second section, gives a progress report on the on-going programs. It is the first report in this style, but it can be considered as a continuation of the earlier Medical Newsletter of SIN. (author) 59 figs., 19 tabs., 61 refs

    A large solid angle array (the Crystal Ball detector) of NaI(Tl) crystals, together with spark and multiwire proportional chambers for charged particle tracking, is used to study the decays of the psi' meson. Cascade reactions of the form psi' → γchi, chi → γpsi, psi → (e + e - or μ + μ - ) are used in this experiment to observe the intermediate chi states and to measure their spin by analyzing the angular correlations among the final-state particles. In addition, the multipole coefficients describing the individual radiative transitions are measured using the angular correlations. Values of J = 2 and J = 1 are obtained for the chi states with masses of 3.55 and 3.51 GeV, respectively. Radiative transitions to and from the chi states are found to be dominantly E1 in nature. The well-established J = 0 chi(3.41) state is observed in a cascade reaction, with a branching ratio BR(psi' → γchi → γγpsi) = (0.06 +- 0.02 +- 0.01)%; the first error describes uncertainties arising from statistics and acceptance corrections, while the second error is systematic. Branching ratios of (1.26 +- 0.08 +- 0.20)% for chi(3.55) and (2.38 +- 0.12 +- 0.38)% for chi(3.51) are consistent with those obtained in previous experiments. Natural line-widths of (4 +- 1) MeV for chi(3.55) and a full width consistent with the resolution of the apparatus for chi(3.51) are obtained

    A sample of J/psi → μ + μ - decays produced by a 225-GeV/c π - beam on nuclear targets has been analyzed for extra muons. Muons observed in coincidence with J/psi production could indicate either the production of charmed particles or the production of pairs of J/psi particles. We find 90% confidence limits of sigma/sub J/DD-bar/sigma/sub J/<0.016 for associated charm production and sigma/sub J/J/sigma/sub J/<0.005 for the production of J/psi pairs

  5. Supply air filters after the nuclear reactor accident at Chernobyl

    1989-01-01

    In the case of increased activity concentration in the air supply air filters are the facility compounds where enhanced activity is collected. Therefore, it was understandable that the people put questions about the doses caused by supply air filters after the nuclear reactor accident at Chernobyl. When comparing the local dose rate at a distance of 1 m in front of filters with the outdoor local dose rate due to dry deposited radionuclides, nearly the same local dose rate results assuming an air flow rate of approx. 60 m 3 /h. Supposing a 10 hours stay at a distance of 1 m in front of filters and an air flow rate of approx. 5000 m 3 /h the same dose is obtained after a 10 days delay as the dose due to outdoor inhalation. At Aachen, the local dose rate near to filters increased up to approx. 10 μSv/h. After a suitable time delay of one month filters could be rejected like normal waste. A review is given on individual measured values

Psi-calculi are significantly more expressive, yet their semantics is as simple......, an interactive proof assistant designed to facilitate formal reasoning about calculi with binders. Our main contributions are twofold. First, we have developed techniques that allow efficient reasoning about calculi that bind multiple names in Nominal Isabelle. Second, we have adopted these techniques...... to mechanise substantial results from the meta-theory of psi-calculi, including congruence properties of bisimilarity and the laws of structural congruence. To our knowledge, this is the most extensive formalisation of process calculi mechanised in a proof assistant to date....

    Full Text Available Tritium (3H is one of the important long-lived radioisotopes in the gaseous effluent from nuclear power plants. In this article, we present the results of 3H monitoring in ambient air samples around the Kaiga Nuclear Power Plant, on the West Coast of India. Air samples were collected by moisture condensation method and the 3H concentration was determined by liquid scintillation spectrometry. The 3H concentration in the 2.3–15 km zone of the power plant varied in the range of <0.04–6.64 Bq m−3 with a median of 0.67 Bq m−3. The samples collected from the 2.3–5 km zone of the power plant exhibit marginally higher concentration when compared to the 5–10 km and 10–15 km zones, which is as expected. The values observed in the present study for Kaiga region are similar to those reported from other nuclear power plants, both within India and other parts of the world.

    1990-08-01

    We have, in cooperation with industry, developed high-efficiency filters made from sintered stainless-steel fibers for use in several air-cleaning applications in the nuclear industry. These filters were developed to overcome the failure modes in present high-efficiency particulate air (HEPA) filters. HEPA filters are made from glass paper and glue, and they may fail when they get hot or wet and when they are overpressured. In developing our steel filters, we first evaluated the commercially available stainless-steel filter media made from sintered powder and sintered fiber. The sintered-fiber media performed much better than sintered-powder media, and the best media had the smallest fiber diameter. Using the best media, we then built prototype filters for venting compressed gases and evaluated them in our automated filter tester. 12 refs., 20 figs

    As pollution peaks are noticed in all big cities with dramatic consequences on health and on the economy, this article first outline these consequences of the use of fossil energies: 480.000 premature deaths in OECD countries due to the consequences of atmospheric pollution which results in heart and respiratory diseases, coronary diseases, cerebrovascular accidents or lung cancers, and nearly 120.000 deaths in dwellings, mainly in developing countries, due to the use of solid fuels for cooking and heating. Figures of the assessment of the economic cost and health impact of air pollution in 53 European countries are given. The author then outlines that the use of nuclear energy does not generate these pollutions: according to a study, nuclear energy avoided 1.8 million deaths between 1971 and 2009, and its replacement by coal would result in 4 to 7 million additional deaths

    Nuclear analytical methods are discussed with a view to their applicability in the determination of air pollutants. It is shown that some methods (use of radioactive kryptonates in automatic analyzers, application of activation analysis, X-ray fluorescence methods) are developed in theory and proven in practice in such an extent to be widely used in the near future in the control of the environment. Many other methods are becoming increasingly important for the solution of specific problems of environmental protection (such as the control of sudden environmental contamination in the proximity of chemical plants and industrial centers).

    Special law on nuclear disaster countermeasures (hereafter called as to nuclear disaster countermeasures low) that is domestic law for dealing with measures for nuclear disaster, was enforced in June, 2000. Therefore, nuclear enterprise was obliged to report accidents as required by nuclear disaster countermeasures law, besides meeting the technical requirement of existent transport regulation. For overseas procurement of plutonium reference materials that are needed for material accountability, A Type package must be transported by air. Therefore, concept of air transport of nuclear fuel materials according to the nuclear disaster countermeasures law was discussed, and the manual including measures against accident in air transport was prepared for the oversea procurement. In this presentation, the concept of air transport of A Type package containing nuclear fuel materials according to the nuclear disaster countermeasures law, and the experience of a transportation of plutonium solution from France are shown.

  14. $J/\\psi$ Absorption in Heavy Ion Collisions

    CERN Document Server

    Maiani, Luciano; Polosa, Antonio; Riquer, V

    2004-01-01

    We present a new calculation of the pi-J/psi dissociation cross sections within the Constituent Quark-Meson Model recently introduced. To discuss the absorption of J/psi in heavy-ion collisions, we assume the J/psi to be produced inside a thermalized pion gas, as discussed by Bjorken, and introduce the corrections due to absorption by nuclear matter as well. We fit the absorption length of the J/psi to the data obtained at the CERN SPS by the NA50 Collaboration for Pb-Pb collisions. Collisions of lower centrality allow us to determine the temperature and the energy density of the pion gas. For both these quantities we find values close to those indicated by lattice gauge calculations for the transition to a quark-gluon plasma. A simple extrapolation to more central collisions, which takes into account the increase of the energy deposited due to the increased nucleon flux, fails to reproduce the break in J/psi absorption indicated by NA50, thus lending support to the idea that an unconfined quark-gluon phase m...

    CERN Document Server

    Trombetta, Giuseppe

    Heavy-flavour hadrons, containing open or hidden charm and beauty quarks, provide one of the most important tools to test our understanding of various aspects of Quantum Chromodynamics (QCD). The heavy quark masses introduce indeed an effective threshold on the coupling of the strong interaction, allowing the hard-scattering process taking place at the initial stage of their formation to be calculated within the framework of perturbative QCD and compared to experimental measurements. In heavy-ion collisions, quarkonia and heavy-flavour hadrons play a further important role as they have long been proposed as ideal probes of the hot and deconfined medium, known as Quark-Gluon Plasma (QGP), which is thought to be produced in such collisions. The large momentum transfers involved in the formation of heavy quarks ensure their production to occur in the very first stages of the collision and allow them to traverse the medium during its full evolution. Different effects related to the presence of Cold Nuclear ...

    Since 1996 the IAEA TS-R-1 regulation included new requirements applicable to transport of fissile materials by air. The later 2005 and 2009 editions confirmed the validity of those provisions. Despite the fact that the IAEA TS-R-1 allows for air shipments of SNF in Type B and Type C packages, the examples of such shipments are not abundant. Nuclear regulatory bodies and transport safety experts are cautious about air shipments of SNF. Why so? What are the risks? What are the alternatives? In this new regulatory framework, in 2009, two air shipments in Type B packages of Research Reactor (RR) Spent Nuclear Fuel (SNF) from Romania and Libya were performed under the U.S. DOE/NNSA RRRFR Program. The first licensing process of such shipment brought up many questions about package and shipment safety from the licensing experts' side and so the scope of analyses exceeded the requirements of IAEA. Under the thorough supervision of Rosatom and witnessed by DOE and CNCAN, all questions were answered by various strength analyses and risk evaluations. But the progress achieved didn't stop here. In 2010-2011, an energy absorption container (EAC) with titanium spheres as absorbers based on the SKODA VPVR/M cask was designed as the first Type C package in the world destined for RR SNF, currently under approval process. At the same time, intense preparations for the safe removal of the Russian-origin damaged RR SNF from Serbia, Vinca were in progress. The big amount of SNF and its rapidly worsening condition imposed as requirements to organize only one shipment as fast as possible, i.e. using at the maximum extent the entire experience available from other SNF shipments. The long route, several transit countries and means of transport, two different casks, new European regulations and many other issues resulted for the Serbian shipment in one of the most complex SNF shipments’ licensing exercise. This paper shows how the international regulatory framework ensures the

  3. Certification of the PSI request for the renewal of the operation license for the Hot Laboratory

    International Nuclear Information System (INIS)

    2014-03-01

    At the Paul Scherrer Institute (PSI), the Hot Laboratory was built in the years 1961 to 1963 in the former EIR in order to make scientific material analyses on highly radioactive material samples and to prepare diagnostic and therapeutically useful radioisotopes. The 1964 safety report with the request for the granting of the operational warrant was revised for the first time in 2004. Further safety reports and radiation protection plans were produced and accepted by the surveying authorities. The operational regulations were revised and approved on a yearly basis by the PSI direction. The regulations reflect the experience gained in 40 years of safe operation and take new regulations in nuclear energy legislation into account. In the years 2000-2002 the Hot Lab was refitted especially with respect to the fields of radiation and fire protection. Presently, the Hot Lab is used for applied material research on highly radioactive samples which mainly come from nuclear power plants, research reactors and the target stations of the PSI accelerator facilities. The investigations on highly radioactive samples and the handling of large quantities of radioisotopes include the possibility of incidents. The analysis of such incidents shows that the legal safety requirements are satisfied. The Swiss Federal Nuclear Safety Inspectorate (ENSI) requirements concerning the protection of personnel, population and environment, as well as the protection against fire, are fulfilled. In the Hot Lab the principle of barriers for the containment of radioactive materials is applied. Open radioactive sources are manipulated in depressurized cells. The air extracted from the cells is filtered before being released to the environment. In the building, the total amount of radioactive materials is limited in order to reduce the exposition of the population in normal operation as well as in case of incidents, and to avoid criticality accidents. Possible weaknesses in this concept can be shown

    1996-01-01

    A phase I aging assessment of high efficiency particulate air filters and activated carbon gas adsorption units was performed by the Pacific Northwest Laboratory as part of the US Nuclear Regulatory Commission's Nuclear Plant Aging Research Program. Information was compiled concerning design features, failure experience, aging mechanisms, effects, and stressors, and monitoring methods. Over 1100 failures, or 12% of the filter installations, were reported as part of a US Department of energy survey. Investigators from other laboratories have suggested that aging could have contributed to over 80% of these failures. Several instances of impaired performance as the result of the premature aging of carbon were reported. Filter aging mechanisms range from those associated with particle loading to reactions that alter the properties of gaskets. Mechanisms that can lead to impaired adsorber performance include the loss of potentially available active sites as a result of the adsorption of moisture or pollutants. Stressors include heat, moisture, radiation, and airborne particles and contaminants. (orig.)

  6. Proton therapy project at PSI

    Particle radiation which might present steeper dose distribution has received much attention as the third particle facility at the Paul Scherrer Institute (PSI), Switzerland. Proton conformation with sharp fall-off is considered to be the radiation beam suitable for confining high doses to a target volume without complications and for verifying which factor out of high RBE or physical dose distribution is more essential for local control in malignant tumors. This paper discusses the current status of the spot scanning method, which allows three dimensional conformation radiotherapy, and preliminary results. Preliminary dose distribution with proton conformation technique was acquired by modifying a computer program for treatment planning in pion treatment. In a patient with prostate carcinoma receiving both proton and pion radiation therapy, proton conformation was found to confine high doses to the target area and spare both the bladder and rectum well; and pion therapy was found to deliver non-homogeneous radiation to these organs. Although there are some obstacles in the proton project at PSI, experimental investigations are encouraging. The dynamic spot scanning method with combination of the kicker magnet, wobbler magnet, range shifter, patient transporter, and position sensitive monitor provides highly confined dose distribution, making it possible to increase total doses and thus to improve local control rate. Proton confirmation is considered to be useful for verifying possible biological effectiveness of negative pion treatment of PSI as well. (N.K.)

    An emission inventory of nonradiological hazardous air pollutants (HAP) was prepared for TVA's Browns Ferry Nuclear Plant (BFN). The purpose of this effort was to determine whether BFN is a major HAP emission source. About 40 specific HAP were identified in products used at FBN. HAP emission totals from BFN were estimated at 6 T/Y, well below the major-source cutoff. Off-site waste disposal reduced gross emission estimates by about 8 percent. HAP emission evaluation by product categories showed the largest portion due to paints and coatings, followed by cleaning compounds. HAP emission breakdown by chemical species showed xylene to be the predominate HAP emitted, followed by methyl ethyl ketone

  8. An alternative way of plotting the data and results of models of $J/\\psi$ suppression

    2003-01-01

    We propose an alternative way of looking at data on anomalous J/ psi suppression. The proposed method is in principle equivalent to the one used by the NA50 Collaboration, but it permits to visualize separate contributions of individual processes responsible for the disintegration of J/ psi 's produced by a hard process in nuclear collisions. The method can be used provided that the time sequence of contributing mechanisms is known or assumed. It offers an alternative graphical presentation of the onset of anomalous J/ psi suppression in Pb-Pb interactions observed by the NA50 Collaboration at the CERN SPS and might contribute to explain why different mechanisms, such as J/ psi suppression by the quark-gluon plasma and by co-movers in the dual parton model or in Monte Carlo microscopic approaches, all lead to an approximate description of anomalous J/ psi suppression.

    1983-09-01

    We have studied the potential for physical or financial disruption of the electric utility system in New York as it may be affected by nuclear power availability, air pollution control policy, inflation, and economic growth. The method of analysis is the EPA-sponsored CCMU model which integrates utility economics, demand forecasting and customer charges, air pollution control, and power plant dispatching. The CCMU model is a partial version of the AUSM; the latter model is being developed to include coal supply and capacity planning. Of all the cases examined, only one type seems to create a severe crisis which leads to possible public reorganization of the industry. These are the cases in which the Shoreham and Nine Mile 2 plants are not operated, and 50% or more of the investment cost is not allowed in the rate base. In these circumstances, the state's utilities would apparently be unable to meet debt obligations and would also need to discontinue dividend payments. The extremity of this situation should be emphasized. These specific cases already assume that liability for debt and dividend payments has been shared equally over all of the state's utilities and customers. It assumes that the state's Power Pool has already implemented a plan by which the principal owners of the two plants are relieved of their principal financial and generating responsibilities. In all other cases studied, the statewide industry appears capable of managing the problems examined

    Objective: According to the regulations of nuclear safety rules and related standards, in-place test of the nuclear air-cleaning systems should be carried out before and during operation of the nuclear facilities, which ensure them to be in good condition. In some special conditions, the use of sample and injection manifolds is required to make the test tracer and ventilating duct air fully mixed, so as to get the on-spot typical sample. Methods: This paper introduces the technology and application of the sample and injection manifolds in nuclear air-cleaning system. Results: Multi point injection and multi point sampling technology as an effective experimental method, has been used in a of domestic and international nuclear facilities. Conclusion: The technology solved the problem of uniformly of on-spot injection and sampling,which plays an important role in objectively evaluating the function of nuclear air-cleaning system.

    At the 'pion factory' of the Swiss Paul Scherrer Institute, a collaboration of PSI, Heidelberg and Zurich (ETH) has recently produced intense beams of positive muons which have kinetic energies as low as 10 eV and with complete polarization (spin orientation). The new results were achieved at a surface muon channel, transporting positive muons from the decay of positive pions stopped at the surface of a pion production target. Surface muons with 4 MeV kinetic energy were transported by a conventional secondary beam channel and partially stopped in a moderator consisting of a layer of solidified noble gas deposited on a cold metallic substrate

    2001-08-01

    Within the CASTOC-project (5th EU FW programme), the environmentally-assisted crack growth (EAC) behaviour of low-alloy reactor pressure vessel (RPV) steels is experimentally investigated under simulated transient and steady-state BWR power operation conditions by 6 European laboratories. The present report contains a summary of the PSI contribution to the Working Package 1 (WP1) of this project. WP1 is an interlaboratory round robin EAC test in simulated BWR/NWC environment under cyclic and static loading conditions. The round robin shall demonstrate the applicability of the used advanced test technique and establishes the technical basis for the decision of test conditions in the other working packages. In the first part of the report, the PSI testing facility/measurement instruments and the applied test and evaluation procedure are discussed in detail. In the second part, the exact test conditions and test results with detailed post-test fractographical evaluation in the SEM are presented. The test results are compared with other PSI results, literature data and nuclear codes. Stable and stationary test conditions within the specified range could be achieved in the PSI test during the whole conditioning and experimental phase. The cyclic crack growth rate results agree well with recent PSI results at a higher dissolved oxygen content of 8 ppm and are slightly below the 'high-sulphur line' of the PLEDGE-model. The crack growth rates are significantly above the ASME XI 'wet' curve. Compared to fatigue crack growth rates in air under otherwise identical test conditions, the effect of the high-temperature water environment resulted in an acceleration of crack growth by a factor of 150-250 under these low-cyclic loading conditions. The test results at constant load confirm the extremely low susceptibility to SCC crack growth under static load at 288 {sup o}C observed in tests at MPA, PSI and in a European Round Robin. They agree well with the RPV

    A detailed study of J/psi hadronic production has been performed in a high statistics experiment (more than 1.5 10 6 J/psi observed in their dimuon decay mode). Data have been taken with incident πsup(+-), Ksup(+-), psup(+-), on hydrogen and platinum targets, at 150, 200 and 280 GeV/c. We find from the observed nuclear dependance of the cross sections, that about 18% of the J/psi are produced diffractively. Using known structure functions of the quarks in the nucleon and in the pion, we derive estimations for the gluon structure functions. (orig.)

    2004-01-01

    In order to investigate chemical behaviors of the graphite during an air-ingress accident in HTGR, the kinetic tests on nuclear graphite IG-110 were performed in chemical reaction dominant regime. In the present experiment, inlet gas flow rate ranged between 8 and 18 SLPM, graphite temperatures and oxygen mole fraction ranged from 540 to 630degC and from 3 to 30% respectively. The test section was made of a quartz tube having 75 mm diameter and 750 mm length and the test specimen machined to the size of 21 mm diameter and 30 mm length was supported at the center of it by the alumina rod. The 15 kW induction heater was installed around the outside of test section to heat the specimen and its temperature was measured by 2 infrared thermometers. The oxidation rate was calculated from the gas concentration analysis between inlet and outlet using NDIR (non-dispersive infrared) gas analyzer. As a result the activation energy (Ea) and the order of reaction (n) were determined within 95% confidence level and the qualitative characteristics of the two parameters were also widely investigated by experimental and analytical methods.

    The compressed air system of nuclear power plants provides pneumatic power for both operation and control of various plant equipment, tools, and instrumentation. Included in the air supply systems are the compressors, coolers, moisture separators, dryers, filters and air receiver tanks that make up the major items of equipment. The service air system provides oil-free compressed air for general plant and maintenance use and the instrument air system provides dry, oil-free, compressed air for both nonessential and essential components and instruments. NRC recommended the periodic checks on GL88-14 'Instrument air supply system problems affecting safety-related equipment'. To ensure that the quality of the instrument air is equivalent to or exceeds the requirement s of ISA-S7.3(1975), air samples are taken at every refueling outage and analyzed for moisture, oil and particulate content. The over all results are satisfied the requirements of ISA-S7.3

    The first axis of research of the NA38 experiment, realized at CERN, is to bring to the fore the quark gluon plasma (QGP). In this aim, the study of the J/{psi} production relatively to dimuon continuum and in correlation with energy density started in 1986. The relative decrease of the J/{psi} production observed was however in agreement with some models without plasma. On the other hand study of the relative production on the {psi}` and J/{psi} must allow to distinguish between nuclear absorption model and QGP. This thesis describes this study made with high statistics data taken in 1992. In this document, the apparatus is describe and especially the electromagnetic calorimeter and its pile-up rejection system which has allowed to save about 40 extra events. On top of this , because of the low {psi}` production cross-section as well as the small mass splitting between the two resonances J/{psi} and {psi}`, thorough study of all the phenomena affecting the mass resolution of the spectrometer was performed. The results show that the ratio {psi}`/{psi} is multiplied by a factor 0.61 when the density obtained during the collisions goes from 1.34 GeV/fm{sup 3} to 2.33 GeV/fm{sup 3} (density at which the plasma is supposed to occur). This ratio is also expressed as a function of the width of the nuclear matter traversed and compared to the results of other experiments. Nevertheless, due to the large error bars, it can`t be claimed that QGP was observed in laboratory. (author). 47 refs., 90 figs., 14 tabs.

    A variety of air cleaning systems may be operating in nuclear power plants and under severe accident conditions, these systems may be treating airborne concentrations of aerosols which are very high. Predictions of airborne aerosol concentrations in nuclear power plant containments under severe accident conditions are reviewed to provide a basis for evaluating the potential effects on the air cleaning systems. The air cleaning systems include filters, absorber beds, sprays, water pools, ice beds, and condensers. Not all of these were intended to operate as air cleaners but will in fact be good aerosol collectors. Knowledge of expected airborne concentrations will allow better evaluation of system performances

Major accomplishments of the past year include: a pioneer solar power-plant; improvements in catalysts and processes for the production of methane from wood; development of characterization tools to improve combustion processes; fuel cells, and batteries under operating conditions; carbon dioxide in forests; and a new dating method for glacial ice. Progress was made in determining the suitability of opalinus clay to store radioactive waste and how iodine exposure could be reduced under normal operation and in the event of a severe accident at a nuclear power-plant. Systems analysis research also included a report on the external environmental costs of electricity and whether the Swiss population are willing to pay for renewable energy. This report only highlights a selection of the work done at PSI in the past year; information about many other ongoing projects can be accessed through our website, (www.psi.ch). (author)

    This paper introduces the design evolution, system schemes and design and construction of main nuclear air cleaning components such as HEPA filter, charcoal adsorber and concrete housing etc. for Qinshan 300MW PWR Nuclear Power Plant (QNPP), the first indigenously designed and constructed nuclear power plant in China. The field test results and in-service test results, since the air cleaning systems were put into operation 18 months ago, are presented and evaluated. These results demonstrate that the design and construction of the air cleaning systems and equipment manufacturing for QNPP are successful and the American codes and standards invoked in design, construction and testing of nuclear air cleaning systems for QNPP are applicable in China. The paper explains that the leakage rate of concrete air cleaning housings can also be assured if sealing measures are taken properly and embedded parts are designed carefully in the penetration areas of the housing and that the uniformity of the airflow distribution upstream the HEPA filters can be achieved generally no matter how inlet and outlet ducts of air cleaning unit are arranged.

  9. Range war: IPALCO's bid for PSI resources

    International Nuclear Information System (INIS)

    Studness, C.M.

    1993-01-01

    IPALCO Enterprises Inc. announced a hostile, unsolicited bid to acquire PSI Resources on March 15. IPALCO's bid for PSI is aggressive and well thought out, which befits the strong incentive that it had to take action. Besides topping Cincinnati Gas ampersand Electric's offering price made late last year, IPALCO took the initiative on three other fronts. First, it filed a lawsuit in federal court in Indianapolis to block the merger between PSI and Cincinnati. The suit claims that the proposed merger violates Indiana law and that PSI and Cincinnati have made false and misleading statements about the benefits of their proposed merger. Second, IPALCO announced it will oppose the merger between PSI and Cincinnati in proceedings before Indiana regulators. Third, IPALCO said it plans to nominate a slate of five candidates to stand election for PSI's Board of Directors at the company's annual shareholders meeting this spring. However, these initiatives and IPALCO's accompanying appeal to Hoosier loyality are little more than diversionary tactics. In the final analysis, whether PSI merges with IPALCO or with Cincinnati will depend rather simply on who is willing to make the highest bid

  10. Inclusive J / $\\psi$ Production at D0

    Energy Technology Data Exchange (ETDEWEB)

    Murphy, Christopher R. [Indiana U.

    1995-04-01

    We present results on inclusive $J/\\psi$ and b-quark production in $p\\bar{p}$ collisions at $\\sqrt{s}$ = 1.8 TeV. The results are based on data collected at the D0 experiment during the 1992-1993 FermiLab collider run. There is excellent agreement between the differential $J/\\psi$ cross section measured at D0 and that measured at the CDF detector. A measurement of the fraction of $J/\\psi$ events due to b-quark decays is presented and we extract from this a measurement of the integrated b-quark cross section. The radiative decays of $_{Xc}$ charmonium states into the $J/\\psi$ is discussed and we present results on the fraction of $J/\\psi$ mesons that are due to $_{Xc}$ decays. We also observe that a fraction of promptly produced $J/\\psi$ mesons is larger than the measured fraction of $J/\\psi$ due to $_{Xc}$ decays and is not accounted for by existing charmonium. production models.

  11. Phenomenology of deflagration and detonation of hydrogen-air mixtures in water cooled nuclear power plants

    1984-01-01

    This paper summarizes fundamentals of the flammability of the hydrogen-air mixtures and hydrogen-air containing added steam or other inerting agent. The flammability behaviour of such gaseous mixtures is described with reference to physical and chemical conditions close enough to those expected in the containment of a nuclear reactor during a LOCA

  12. psi and excess leptons in photoproduction

    Ritson, D.M.

    1976-03-01

    The A-dependence of psi photoproduction was measured on beryllium and tantalum. From this it is found sigma/sub psi N/ = 2.75 +- 0.90 mb. A study was made of excess leptons relative to pion production in photoproduction. A μ/π ratio of 1.40 +- 0.25 x 10 -4 was found at 20 GeV incident photon energy. The energy dependence of psi photoproduction was determined and appeared to have a ''pseudo-threshold'' at 12 GeV

  13. AEC Regulatory view of the reliability of air cleaning systems in nuclear facilities

    International Nuclear Information System (INIS)

    Bellamy, R.R.; Zavadoski, R.W.

    1975-01-01

    Air cleaning systems in nuclear facilities can be divided into three categories: ventilation exhaust systems, containment atmosphere cleanup systems, and process offgas systems. These systems have been the subject of numerous reports, regulatory guides, discussions, and meetings. Some of the analyses have been critical of the operation and design of these air cleaning systems--in particular, the engineered safety features containment atmosphere cleanup systems. Although for the most part the criticism is applicable, and recognizing that there are a number of unresolved issues pertaining to gaseous waste management systems, there are data to show that air cleaning systems in use in nuclear facilities are performing their intended function.

  14. Techniques for controlling air pollution from the operation of nuclear facilities. Report of a panel

    International Nuclear Information System (INIS)

    1966-01-01

    This manual is provided for the guidance of those persons or authorities who are responsible for the organization, control and operation of ventilation systems and air-cleaning installations in nuclear establishments. It is intended to generalize about existing experience in the operation of such systems at nuclear facilities including reactors and laboratories for production, use and handling of radionuclides and other toxic materials. This manual will provide designers and operators of nuclear facilities in which ventilation and air-cleaning systems are used with the factors which have to be considered to create safe working conditions inside facilities and without polluting the atmosphere or the environment to a hazardous level.

  17. Measurement of an excess in the yield of J/$\\psi$ at very low-$p_{\\rm T}$ in Pb--Pb collisions with the ALICE detector

    CERN Document Server

    Massacrier, Laure

    2015-01-01

    We report on the measurement of J/$\\psi$ production at very low transverse momentum ($p_{\\rm T} < $ 300 MeV/$c$) in Pb--Pb collisions performed with the ALICE detector at the LHC. We find an excess in the yield of J/$\\psi$ with respect to expectations from hadronic production. Coherent photo-production of J/$\\psi$ is proposed as a plausible origin of this excess. We show the nuclear modification factor of very low-$p_{\\rm T}$ J/$\\psi$ as a function of centrality. Then we measure the J/$\\psi$ coherent photoproduction cross section in peripheral events assuming that it is the mechanism at the origin of the measured excess. It's worth noting that the observation of J/$\\psi$ coherent photoproduction in Pb--Pb collisions at impact parameters smaller than twice the nuclear radius has never been observed so far and would open new theoretical challenges.

  18. Applied research on air pollution using nuclear-related analytical techniques

    International Nuclear Information System (INIS)

    1994-01-01

    A co-ordinated research programme (CRP) on applied research on air pollution using nuclear-related techniques is a global CRP which will run from 1992-1996, and will build upon the experience gained by the Agency from the laboratory support that it has been providing for several years to BAPMoN - the Background Air Pollution Monitoring Network programme organized under the auspices of the World Meterological Organization. The purpose of this CRP is to promote the use of nuclear analytical techniques in air pollution studies, e.g. NAA, XFR, and PIXE for the analysis of toxic and other trace elements in suspended particulate matter (including air filter samples), rainwater and fog-water samples, and in biological indicators of air pollution (e.g. lichens and mosses). The main purposes of the core programme are i) to support the use of nuclear and nuclear-related analytical techniques for practically-oriented research and monitoring studies on air pollution ii) to identify major sources of air pollution affecting each of the participating countries with particular reference to toxic heavy metals, and iii) to obtain comparative data on pollution levels in areas of high pollution (e.g. a city centre or a populated area downwind of a large pollution source) and low pollution (e.g. rural areas). This document reports the discussions held during the first Research Co-ordination Meeting (RCM) for the CRP which took place at the IAEA Headquarters in Vienna. Refs, figs and tabs

    Schuler, C.; Butterweck-Dempewolf, G.

    1997-05-01

    The 1996 Radon Intercomparison Exercise at PSI was organized by the PSI Reference Laboratory for Radon Gas Activity Concentration Measurements. A total of 14 laboratories, companies and institutions participated with radon gas detectors and measuring instruments. The detectors and instruments were exposed in the PSI radon chamber during seven days in a reference atmosphere with an average radon gas concentration of about 6000 Bqm -3 . Comparison of the results of electret ionization chambers, track etch detectors and measuring instruments with the PSI target value showed the criteria for traceability and reproducibility demanded by the Federal Office for Health for the acknowledgement of Swiss Radon Gas Measurement Laboratories to be fulfilled for all participants. Exposure of track etch detectors stored for more than one year demonstrated that this detector type can suffer sensitivity loss by a too long storage period. (author) figs., tabs., refs

    1999-01-01

    Using the color evaporation model (CEM), we consider the decay rate of B -> J/PSI + X and the polarization of J/PSI therein, and we compare the results with the data and with the predictions by the nonrelativistic quantum chromodynamics (NRQCD) approach. In the CEM, we use the input parameter determined from photo/hadro productions of J/PSI, and we find that it is difficult to make the CEM predictions confront with the CLEO data on these observables.

    Supermirror coatings for the seven neutron guides of the continuous spallation source SINQ at PSI are being produced on a DC-magnetron sputtering plant at PSI since April 1993 at a rate of up to 2 meters of guide per day. All Supermirrors are characterised after production on the test spectrometer TOPSI at reactor Saphir. The more than 300 production runs allow interesting comparisons between coatings made on various types of glasses. (author) 3 figs

  5. J/psi physics at BEPC

    International Nuclear Information System (INIS)

    Chanowitz, M.S.

    1984-06-01

    J/psi physics is discussed which will be of interest at T > 1988, the period of operation of the Beijing Electron Positron Collider. Emphasis is placed on the gluonic states which are best studied in radiative J/psi decay. The difficulties of these studies are discussed and the need for very high statistics is stressed. In particular it is essential to partial-wave-analyze the hadronic final states produced in J/psi → γX. An estimate using fixed target data suggests that 0(10 8 ) J/psi decays are needed to do an unambiguous partial wave analysis for hadron masses up to about 2 GeV. This requirement is an excellent match to the BEPC design parameters, which imply production of 0(10 8 ) J/psi's per year. With a J/psi production rate an order of magnitude greater than other electron-positron storage rings, BEPC will be a unique world facility for these studies. 58 references

    1985-01-01

    In the past 20 years, with the utilization of nuclear technology in China, air cleaning techniques were developed to prevent the environment from pollution caused by radioactive materials and to ensure the safety of occupational personnel. The technical developments involve many fields including the manufacture of filter media and adsorbents; the application of filters and iodine adsorbers and the testing of them; the improvement of instruments and methods for aerosol concentration measurement; the retention of radioactive noble gases; and others. As nuclear power stations are to be built in China, nuclear air cleaning will be advancing more rapidly. Many programs have been scheduled, such as producing other types of adsorbers, moisture separators, nuclear grade HEPA filters that have excellent performance to resist adverse circumstances, and in-place testing for units of ventilation systems in nuclear facilities. These programs are discussed

    Air spaces in a deep geologic repository for nuclear high level waste will have an important effect on the long-term performance of the waste package. The important temperature effects of an annular air gap surrounding a high level waste canister are determined through 3-D numerical modeling. Air gap properties and parameters specifically analyzed and presented are the air gap size, surfaces emissivity, presence of a sleeve, and initial thermal power generation rate; particular emphasis was placed on determining the effect of these variables have on the canister surface temperature. Finally a discussion based on modeling results is presented which specifically relates the results to NRC regulatory considerations

    Using the selective I 2 sorption materials DSM 10 and DSM 11 measurements were performed with radioiodine species samplers in the exhaust air of a research reactor and of several nuclear power stations (BWR, PWR). The radioiodine species samplers were used upstream and downstream of iodine filters (containment exhaust air stand-by filter, shutoff room exhaust air filter) as well as in the exhaust air of the stack. The results obtained by use of DSM 10 and DSM 11 generally agreed. The percentage of aerosol iodine was low in all cases ( [de

    A measurement of $J/\\psi$ and $\\psi(2\\mathrm{S})$ production is presented. It is based on a data sample from Pb+Pb collisions at $\\sqrt{s_{\\mathrm{NN}}}$ = 5.02 TeV and $pp$ collisions at $\\sqrt{s}$ = 5.02 TeV recorded by the ATLAS detector at the LHC in 2015, corresponding to an integrated luminosity of 0.42 nb$^{-1}$ and 25 pb$^{-1}$ in Pb+Pb and $pp$, respectively. The measurements of per-event yields, nuclear modification factors, and non-prompt fractions are performed in the dimuon decay channel for $9 < p_{T}^{\\mu\\mu} < 40$ GeV in dimuon transverse momentum, and $-2.0 < y_{\\mu\\mu} < 2.0$ in rapidity. Strong suppression is found in Pb+Pb collisions for both prompt and non-prompt $J/\\psi$, as well as for prompt and non-prompt $\\psi(2\\mathrm{S})$, increasing with event centrality. The suppression of prompt $\\psi(2\\mathrm{S})$ is observed to be stronger than that of $J/\\psi$, while the suppression of non-prompt $\\psi(2\\mathrm{S})$ is equal to that of the non-prompt $J/\\psi$ within uncertainties,...

    A measurement of $J/\\psi$ and $\\psi(2\\mathrm{S})$ production is presented. It is based on a data sample from Pb+Pb collisions at $\\sqrt{s_{\\mathrm{NN}}}$ = 5.02 TeV and $pp$ collisions at $\\sqrt{s}$ = 5.02 TeV recorded by the ATLAS detector at the LHC in 2015, corresponding to an integrated luminosity of $0.42\\mathrm{nb}^{-1}$ and $25\\mathrm{pb}^{-1}$ in Pb+Pb and $pp$, respectively. The measurements of per-event yields, nuclear modification factors, and non-prompt fractions are performed in the dimuon decay channel for $9 < p_{T}^{\\mu\\mu} < 40$ GeV in dimuon transverse momentum, and $-2.0 < y_{\\mu\\mu} < 2.0$ in rapidity. Strong suppression is found in Pb+Pb collisions for both prompt and non-prompt $J/\\psi$, as well as for prompt and non-prompt $\\psi(2\\mathrm{S})$, increasing with event centrality. The suppression of prompt $\\psi(2\\mathrm{S})$ is observed to be stronger than that of $J/\\psi$, while the suppression of non-prompt $\\psi(2\\mathrm{S})$ is equal to that of the non-prompt $J/\\psi$ withi...

    The production of J/$\\psi$ and $\\psi(2S)$ was measured with the ALICE detector in Pb-Pb collisions at the LHC. The measurement was performed at forward rapidity ($2.5 < y < 4 $) down to zero transverse momentum ($p_{\\rm T}$) in the dimuon decay channel. Inclusive J/$\\psi$ yields were extracted in different centrality classes and the centrality dependence of the average $p_{\\rm T}$ is presented. The J/$\\psi$ suppression, quantified with the nuclear modification factor ($R_{\\rm AA}$), was studied as a function of centrality, transverse momentum and rapidity. Comparisons with similar measurements at lower collision energy and theoretical models indicate that the J/$\\psi$ production is the result of an interplay between color screening and recombination mechanisms in a deconfined partonic medium, or at its hadronization. Results on the $\\psi(2S)$ suppression are provided via the ratio of $\\psi(2S)$ over J/$\\psi$ measured in pp and Pb-Pb collisions.

  13. Air-conditioning and ventilation systems and components of nuclear facilities

    International Nuclear Information System (INIS)

    2006-01-01

    The Guide defines the requirements for the design, implementation and operation of the air-conditioning and ventilation systems of nuclear facilities belonging to safety classes 3 and 4, and for the related documents to be submitted to STUK (Radiation and Nuclear Safety Authority, Finland). Furthermore, the Guide describes the inspections of air-conditioning and ventilation systems to be conducted by STUK during construction and operation of the facilities. As far as systems and components belonging to safety class 2 are concerned, STUK sets additional requirements case by case. In general, air-conditioning systems refer to systems designed to manage the indoor air cleanness, temperature, humidity and movement. In some rooms of a nuclear power plant, ventilation systems are also used to prevent radioactive materials from spreading outside the rooms. Guide YVL1.0 defines the safety principles concerning the air-conditioning and ventilation of nuclear power plants. Guide YVL2.0 gives the requirements for the design of nuclear power plant systems. In addition, YVLGuide groups 3, 4, 5 and 7 deal with the requirements for air-conditioning and ventilation systems with regard to the mechanical equipment, fire prevention, electrical systems, instrumentation and control technology, and the restriction of releases. The rules and regulations issued by the Ministry of the Environment and the Ministry of the Interior (RakMK, the Finnish building code) concerning the design and operation of air-conditioning and ventilation systems and the related fire protection design bases also apply to nuclear facilities. Exhaust gas treatment systems, condenser vacuum systems of boiling water reactor plants and leak collection systems are excluded from the scope of this Guide

  14. Ventilation and air-conditioning system for PWR nuclear power plant

    International Nuclear Information System (INIS)

    Ohmoto, Kenji

    1987-01-01

    This report outlines the ventilation and air conditioning facilities for PWR nuclear power plant as well as design re-evaluation and optimization of ventilation and air-conditioning. The primary PWR installations are generally housed in the nuclear reactor building, auxiliary buildings and control building, which are equipped with their own ventilation and air-conditioning systems to serve for their specific purposes. A ventilation/air-conditioning system should be able to work effectively not only for maintaining the ordinary reactor operation but also for controlling the environmental temperature in the event of an accident. Designing of a ventilation/air-conditioning system relied on empirical data in the past, but currently it is performed based on information obtained from various analyses to optimize the system configuration and ventilation capacity. Design re-evaluation of ventilation/air-conditioning systems are conducted widely in various areas, aiming at the integration of safety systems, optimum combination of air-cooling and water-cooling systems, and optimization of the ventilation rate for controlling the concentrations of radioactive substances in the atmosphere in the facilities. It is pointed out that performance evaluation of ventilation/air-conditioning systems, which has been conducted rather macroscopically, should be carried out more in detal in the future to determine optimum air streams and temperature distribution.

    The methods of neutron activation, both instrumental and radiochemical, and atomic absorption spectrophotometry are used in a study of the concentrations of Al, As, Br, Cd, Cl, Co, Cr, Cu, Fe, Hg, Mn, Sb, Sc, Se, Si, V, Zn and Pb in airborne particulate matter collected from 7 permanent and 9 temporary air quality monitoring stations. The location of the stations are urban residential, suburban residential, mixed (commercial and residential), commercial and industrial areas and near major roads in Bangkok Metropolitan areas. Air sampling is performed once a month for 24 hours continuously using the high volume air sampler (GMW 2000 H) and for 5, 10, and 15 days continuously using an Anderson Air Sampler (SIBATA AN-200). The elements As, Cd and Cu are determined destructively using ion exchange chromatography while Hg and Se are determined by the dry combustion technique. The determination of Pb was done by atomic absorption spectrophotometry. The results of Pb concentrations in airborne particulate matters, collected during 1987 to 1991, were reported by the Office of the National Environment Board. Levels of Pb content were found to be lower than the National Ambient Air Quality Standards. (author). 3 refs, 4 tabs

  18. Internal gelation at PSI. The past and the future

    International Nuclear Information System (INIS)

    Pouchon, Manuel A.; Ingold, Franz

    2009-01-01

    The Paul Scherrer Institute used to be very active in fuel fabrication R and D using the internal gelation process, which is a promising production method for spherical nuclear fuel. Such fuel kernels can be directly packed in a cylindrical cladding (a sphere-pac pin), or they can be coated in the TRISO concept. The internal gelation offers several advantages, as it is aqueous up to the forming of the sphere. Consequently, the process is almost dustless, with lower risk of incorporation. The production does not require mechanical and maintenance intensive equipment, as for example presses and grinding machines necessary for pellet type fuel. Especially for low decontaminated fuel coming from aqueous reprocessing, this offers a great advantage, because the production line can easily be handled remotely in a hot cell. In the past, many different fuel matrices were produced and tested at PSI (carbide, nitride and oxide fuels). The paper summarizes the past activities, and some important findings. Furthermore, future perspectives of this concept are shown. These are especially seen in context of Generation IV nuclear systems such as the sodium cooled fast reactor (SFR), the very high temperature reactor (VHTR), and the gas cooled fast reactor (GFR). The paper describes the former production line, which was a classical internal gelation process. Some advantages and disadvantages of this system will be illustrated which lead to a new project at PSI. A silicon oil-free system will be developed over the next years. The oil as a heat carrier is replaced by a cavity, where microwaves act on falling drops and lead to the desired gelation before the spheres drop into a washing solution. The idea of a microwave gelation has already been tested at several laboratories in the past. The paper gives an overview of these activities. Finally the concept of the new production at PSI is introduced. (author)

    Gaiser, J.E.

    1982-08-01

    The Crystal Ball NaI(T1) detector was used to study the photon spectra from the following inclusive charmonium decays: e + e - → J/psi → #betta# + hadrons and e + e - → psi' → #betta# + hadrons. Data were collected at the Stanford Linear Accelerator Center's electron-positron colliding beam machine, SPEAR. The Crystal Ball detector consists of a highly segmented array of 732 NaI(T1) crystals (16 radiation lengths) covering approx. = 98% of 4π steradians, and is used to measure the photon energies, directions, and lateral shower distributions. This detector is excellently suited for studying the radiative transitions among the charmonium family of states: (1) from psi' to the triplet P states, chi(3415), chi (3510), chi(3550); (2) from psi' and J/psi to the singlet S state eta/sub c/(2984); and (3) from psi' to the radially excited singlet S state eta'/sub c/(3592). The analysis of 1.8 x 10 6 psi' and 2.2 x 10 6 J/psi decays yields the following spectrum of states: chi 0 (3418), chi 1 (3512), chi 2 (3558), eta/sub c/(2984), and eta'/sub c/(3592), each with a +-4 meV error on its mass. The branching ratios are measured to be: B(psi' → #betta# chi 0 1 2 ) = (9.9 +- 0.5 +- 0.8)%, (9.0 +- 0.5 +- 0.7)%, and (8.0 +- 0.5 +- 0.7)%, respectively; B(psi' → #betta# eta/sub c/) = 0.28 +- 0.06)% and B(J/psi → #betta# eta/sub c/) = 1.27 +- 0.36)%; and B(psi' → #betta# eta'/sub c/) = (0.5-1.2)% at the 90% confidence level. Values for the natural line widths are obtained: GAMMA(chi 0 1 2 ) = (13.5-20.4) MeV, < 3.8 MeV, (0.85-4.9) MeV, respectively (90% C.L.); GAMMA(eta/sub c/) = 11.5 +4.5/-4.0) MeV; and GAMMA(eta'/sub c/) < 7 MeV (90% C.L.). Cascade product branching ratios B(psi' → #betta# chi/sub J/).B(chi/sub J/ → #betta#J/psi) were measured for J = 1 and 2 to be: (2.56 +- 0.12 +- 0.20)% and (0.99 +- 0.10 +- 0.08)% respectively. No signal was seen for the J = 0 transition

    PSI domains are cysteine-rich modules found in extracellular fragments of hundreds of signaling proteins, including plexins, semaphorins, integrins, and attractins. Here, we report the solution structure of the PSI domain from the human Met receptor, a receptor tyrosine kinase critical for proliferation, motility, and differentiation. The structure represents a cysteine knot with short regions of secondary structure including a three-stranded antiparallel β-sheet and two α-helices. All eight cysteines are involved in disulfide bonds with the pattern consistent with that for the PSI domain from Sema4D. Comparison with the Sema4D structure identifies a structurally conserved core comprising the N-terminal half of the PSI domain. Interestingly, this part links adjacent SEMA and immunoglobulin domains in the Sema4D structure, suggesting that the PSI domain serves as a wedge between propeller and immunoglobulin domains and is responsible for the correct positioning of the ligand-binding site of the receptor

    Full Text Available “How can Psi Chi best partner with international psychologists to expand the honor society world-wide?” This has been an important question since 2009, when the 1,100 chapters of Psi Chi in the United States voted to become “The International Honor Society in Psychology”. This report updates and expands on a unique symposium offered at the 120th meeting of the American Psychological Association in Orlando, Florida, in August of 2012 - the first symposium on the Presidential theme of “Building Bridges” between Psi Chi and international psychology [8]. Here, seven leaders in international psychology in North and South America join to address different aspects of this timely question--with many suggestions on how to “build bridges” to expand Psi Chi globally. It was in part due to this historic symposium that in 2013 Guatemala became the first nation in Latin America, and Russia the first nation in mainland Europe to launch a chapter of Psi Chi.

    Romania safely air shipped 23.7 kilograms of Russian origin highly enriched uranium (HEU) spent nuclear fuel from the VVR S research reactor at Magurele, Romania, to the Russian Federation in June 2009. This was the world’s first air shipment of spent nuclear fuel transported in a Type B(U) cask under existing international laws without special exceptions for the air transport licenses. This shipment was coordinated by the Russian Research Reactor Fuel Return Program (RRRFR), part of the U.S. Department of Energy Global Threat Reduction Initiative (GTRI), in cooperation with the Romania National Commission for Nuclear Activities Control (CNCAN), the Horia Hulubei National Institute of Physics and Nuclear Engineering (IFIN-HH), and the Russian Federation State Corporation Rosatom. The shipment was transported by truck to and from the respective commercial airports in Romania and the Russian Federation and stored at a secure nuclear facility in Russia where it will be converted into low enriched uranium. With this shipment, Romania became the 3rd country under the RRRFR program and the 14th country under the GTRI program to remove all HEU. This paper describes the work, equipment, and approvals that were required to complete this spent fuel air shipment.

    The proliferation security initiative (PSI), launched by President Bush on May 31, 2003, aims at intercepting any transfer of mass destruction weapons, of their vectors and related equipments, towards or coming from countries or organizations suspected to have a proliferation activity. This initiative, which involves coercive means to fight against proliferation, raises international lawfulness and legal questions, the answers of which are today under construction. This article analyzes the place of the European Union in the PSI, the action means (optimization of existing means, cooperation between intelligence and interception services), and the PSI stakes (lawfulness with respect to the international law, bilateral agreements, draft boarding agreement, sustain of the United Nations, widening of the partnership and of the field of action).

    2017-09-26

    A nuclear reactor includes a reactor core comprising fissile material disposed in a reactor pressure vessel. A radiological containment contains the nuclear reactor. A containment compartment contains the radiological containment. A heat sink includes a chimney configured to develop an upward-flowing draft in response to heated fluid flowing into a lower portion of the chimney. A fluid conduit is arranged to receive fluid from the containment compartment and to discharge into the chimney. A filter may be provided, with the fluid conduit including a first fluid conduit arranged to receive fluid from the containment compartment and to discharge into an inlet of the filter, and a second fluid conduit arranged to receive fluid from an outlet of the filter and to discharge into the chimney. As the draft is developed passively, there is no need for a blower or pump configured to move fluid through the fluid conduit.

  10. Sizing of air cleaning systems for access to nuclear plant spaces

    Estreich, P.J.

    A mathematical basis is developed to provide the practicing engineer with a method for sizing air-cleaning systems for nuclear facilities. In particular, general formulas are provided to relate cleaning and contamination dynamics of an enclosure such that safe conditions are obtained when working crews enter. Included in these considerations is the sizing of an air-cleaning system to provide rapid decontamination of airborne radioactivity. Multiple-nuclide contamination sources, leak rate, direct radiation, contaminant mixing efficiency, filter efficiencies, air-cleaning-system operational modes, and criteria for maximum permissible concentrations are integrated into the procedure.

    Martin Blanco, Javier

    2017-01-01

    The understanding of charmonium production in PbPb collisions requires the inclusion of many phenomena, such as dissociation in the quark gluon plasma and statistical recombination, on top of cold nuclear matter effects. Measurements of charmonium production in pPb collisions are crucial to disentangle the effects related to the presence of a quark gluon plasma from cold nuclear matter effects. In this paper, final prompt J/$\\psi$ results in pPb collisions at \\mbox{$\\sqrt{s_{\\mathrm{NN}}}$} $= 5.02$ TeV are presented, including the new measurement of the $R_{\\mathrm{pPb}}$ using the 2015 pp data taken at the same energy. In addition, new results are reported regarding the prompt $\\psi$(2S) meson production in pPb collisions at 5.02 TeV as a function of transverse momentum and rapidity. Final results on the relative J/$\\psi$ and $\\psi$(2S) modification, based on the pp and PbPb data collected at 5.02 TeV by CMS in 2015, are also reported.

    Results are presented on the elastic and inelastic production of psi (3.1). The elastic data are qualitative agreement with the predictions of photon-gluon fusion but have a steeper dependence on Q 2 than the model predicts. A QCD calculation accounts well for the shape of the inelastic data in inelasticity, Q 2 and E/sub γ/, but fails to account for the absolute cross section. At 209 GeV, the cross-section for elastic psi production is 0.36 +- 0.07 nb; for inelastic, 0.28 +- 0.06nb

    The status and ranking of any country, in the context of globalisation, is decided by its economic progress, which is directly linked into power generation. The power is generated by many routes and the nuclear and thermal routes are noteworthy among them. As the power production and its associated activities may cause qualitative deterioration, it is essential to study the impact of power production on atmospheric environment. In this connection, a comparative study has been carried out to assess the air quality with special reference to criteria pollutants in the vicinity of nuclear and thermal power stations. In the present investigation, the air samples are collected on weekly basis and the pollutants such as sulphur dioxide (SO 2 ), nitrogen oxides (NOx), carbon monoxide (CO), suspended particulate matter (SPM) and respirable particulate matter (RPM) are estimated by adopting standard procedures set by United States-Environmental Protection Agency (US-EPA) and Central Pollution Control Board (CPCB). As the micro meteorological parameters influence on the status of air quality, simultaneous measurements of these parameters are also carried, out during sampling. It is studied that estimated concentrations of all criteria pollutants in the vicinity of these power stations are within the permissible limits set by CPCB. On the basis of the generated database pertaining to the concentrations of criteria air pollutants in the vicinity of nuclear and thermal power stations, it is concluded that nuclear power production may be considered as a viable option in terms of environmental protection in our country.

    Irradiation tests and post-irradiation examinations in the framework of JNC-PSI-NRG collaboration project will be performed in 2003-2005. Irradiation fuel pins will be fabricated by the middle of 2003. The fabrication procedure for irradiation fuel pins has been started in 2001. Several fabrication tests and qualification tests in JNC and PSI (Paul Scherrer Institut, Switzerland) have been performed before the fuel pin fabrication. According to the design assignment between PSI and JNC in the frame of this project, PSI should make specification documents for the fuel pellet, the sphere-pac fuel particles, the vipac fuel fragments, and the fuel segment fabrication. JNC should make the fabrication drawings for irradiation pins. JNC has been performed the fuel design in cooperation with PSI and NRG (Nuclear Research and Consultancy Group, Holland). In this project, the pelletized fuel, the sphere-pac fuel, and the vipac fuel will be simultaneously irradiated on HFR (High Flux Reactor, Holland). The fabrication drawings have been made under the design assignment with PSI, and consist of the drawings of MOX pellet, thermal insulator pellet, pin components, fuel segments, and the constructed pin. The fabrication drawings were approved in October 2001, but after that, the optimization of specifications was discussed and agreed among all partners. According to this agreement, the fabrication drawings were revised in January 2002. After the earlier revision, the shape of particle retainer to be made by PSI was modified from its drawing beforehand delivered. In this report, the fabrication drawings revised again will be shown, and the fabrication procedure (welding Qualification Tests) will be modified in accordance with the result of discussion on the 3rd technical meeting held in September 2002. These design works have been performed in Fuel Design and Evaluation Group, Plutonium Fuel Fabrication Division, Plutonium Fuel Center under the commission of Plutonium Fuel

  2. Research activities related to accelerator-based transmutation at PSI

    International Nuclear Information System (INIS)

    Wydler, P.

    1993-01-01

    Transmutation of actinides and fission products using reactors and other types of nuclear systems may play a role in future waste management schemes. Possible advantages of separation and transmutation are: volume reductions, the re-use of materials, the avoidance of a cumulative risk, and limiting the duration of the risk. With its experience in reactor physics, accelerator-based physics, and the development of the SINQ spallation neutron source, PSI is in a good position to perform basic theoretical and experimental studies relating to the accelerator-based transmutation of actinides. Theoretical studies at PSI have been concentrated, so far, on systems in which protons are used directly to transmute actinides. With such systems and appropriate recycling schemes, the studies showed that considerable reduction factors for long-term toxicity can be obtained. With the aim of solving some specific data and method problems related to these types of systems, a programme of differential and integral measurements at the PSI ring accelerator has been initiated. In a first phase of this programme, thin samples of actinides will be irradiated with 590 MeV protons, using an existing irradiation facility. The generated spallation and fission products will be analysed using different experimental techniques, and the results will be compared with theoretical predictions based on high-energy nucleon-meson transport calculations. The principal motivation for these experiments is to resolve discrepancies observed between calculations based on different high-energy fission models. In a second phase of the programme, it is proposed to study the neutronic behaviour of multiplying target-blanket assemblies with the help of zero-power experiments set up at a separate, dedicated beam line of the accelerator.

    International Nuclear Information System (INIS)

    Rose, D.J.

    1985-01-01

    An increasingly important advantage of nuclear power is its minimal air pollution, in particular the absence of combustion products such as acid rain and carbon dioxide. Developing a consensus about acceptable limits of such pollutants is a slow process that culminates in domestic an international agreements. Therefore, the pace of adoption of new technologies, nuclear power included, is often controlled by the level and intensity of debate, rather than by the technology alone. The state of understanding and consensus about local and long-range transboundary air pollution is therefore germane to the nuclear sector. Progress over the past several decades, mainly between the United States and Canada and within Europe, in developing a more comprehensive and effective international consensus, both informal and formal, is reviewed. There appears to be a trend toward more effective international participation in seeking a less-polluting world, albeit it is punctuated at times by unconcern

Those methods were used to study the pollution of atmospheric particulate matter (PM) in Shanghai. The speciation of Cr, Mn, Cu, and Zn in the PM10 and PM2.5 and different character of vehicle exhausted particles from other emission sources were studied. Source apportionment of the atmospheric lead was calculated with a combined method of lead isotope ratios and lead mass balance, along with μ-PIXE analysis of single particles and pattern recognition of the spectra. The fabricated ultrafine particles to simulate aerosol particle was used to study the translocation from alveolus into circulation across the air blood barrier

    Sorption, co-precipitation and re-crystallisation are important retention processes for dissolved contaminants (radionuclides) migrating through the sub-surface. The retention of elements is usually measured by empirical partition coefficients (Kd), which vary in response to many factors: temperature, solid/liquid ratio, total contaminant loading, water composition, host-mineral composition, etc. The Kd values can be predicted for in-situ conditions from thermodynamic modelling of solid solution, aqueous solution or sorption equilibria, provided that stoichiometry, thermodynamic stability and mixing properties of the pure components are known (Example 1). Unknown thermodynamic properties can be retrieved from experimental Kd values using inverse modelling techniques (Example 2). An efficient, advanced tool for performing both tasks is the Gibbs Energy Minimization (GEM) approach, implemented in the user-friendly GEM-Selector (GEMS) program package, which includes the Nagra-PSI chemical thermodynamic database. The package is being further developed at PSI and used extensively in studies relating to nuclear waste disposal. (author)

  12. Use of nuclear and nuclear-related analytical techniques in studies of trace and minor elements in air pollution

    Among nuclear and nuclear-related analytical techniques, neutron activation and X-ray fluorescence analysis are particularly useful for environmental studies owing to their non-destructive character and multi-element capability. In this work, procedures for k o -standardized instrumental neutron activation analysis (INAA) and energy-dispersive X-ray fluorescence (EDXRF) spectrometry for trace and minor elements in air pollution studies were investigated. The methods applied were validated by the analysis of suitable reference materials. Using INAA, 20 experimentally obtained elemental values out of 21 certified and all 29 experimentally obtained values compared with 'consensus' values (for the elements where no certified numbers are available) in two SRMs were statistically indistinguishable. Also, the contents of 28 elements in candidate NIST SRM 1573a Tomato Leaves are reported. The EDXRF results were statistically indistinguishable from certified values for eight out of nine elements in NIST SRM 3087. The detection limit for this method is around at 0.1 μg cm -2 per element, so in BCR CRM No. 128, which is intended for ambient air pollution data, only Fe and Zn out of 14 elements reported in the certificate were detected with acceptable precision (i.e., 10%) owing to the very low air particulate matter loading, lying in the region of only 250 μg cm -2 .

    Radionuclides handled in nuclear medicine departments are often characterized by high volatility and short half-life. It is generally difficult to monitor directly the intake of these short-lived radionuclides in hospital staff: this makes measuring air contamination of utmost interest. The aim of the present work is to provide a method for the evaluation of internal doses to workers in nuclear medicine, by means of an air activity sampling detector, to ensure that the limits prescribed by the relevant legislation are respected. A continuous air sampling system measures isotope concentration with a Nal(TI) detector. Energy efficiency of the system was assessed with GEANT4 and with known activities of 18F. Air is sampled in a number of areas of the nuclear medicine department of the IRST-IRCCS hospital (Meldola- Italy). To evaluate committed doses to hospital staff involved (doctors, technicians, nurses) different exposure situations (rooms, times, radionuclides etc) were considered. After estimating the intake, the committed effective dose has been evaluated, for the different radionuclides, using the dose coefficients mandated by the Italian legislation. Error propagation for the estimated intake and personal dose has been evaluated, starting from measurement statistics.

    The impact development of Nuclear power plant in Malaysia, can be very negative to the nearby population, causing public restlessness and consequently affecting the image of the authorities in the countries. The precise source of the pollution from the nuclear power plant must be determined, pollution emission level and the meteorological conditions are needed to predict and established the ambient air to the save level at the perimeter fence of the plant and address it with respect to the radiological ambient standards. Upon modeling using an established package as well as site measurements, the radiological level at the perimeter fence of the plant must deduced and lower than the normal ambient level. Based on this issue, a modeling study was made in vicinity of Malaysian Nuclear Agency TRIGA reactor in the area of Bangi, Selangor to evaluate the possibility of movement of air around the area and their impact. This paper will address and discuss the modeling base on the data getting from Meteorological Department such as measurement of wind speed, temperature, humidity, ambient air radiological concentration and ect. The purpose of Air Dispersion Modeling is to establish the critical ambient emission level, as well as radiological modeling. The focus will be made on exploring the use of Ausplume modeling to develop correlations between the radiological concentrations, chemical compositions and ambient model for emission controls.

    The production rates of heavy quarkonia states in A-A collisions provide sensitive probes to the hot and dense QGP. However, a reference for understanding the dissociation in the hot medium is necessary; p-A collisions open the possibility to study heavy quarkonia states in a smaller system. This is an important step in forming a baseline for understanding A-A collisions, as well as an investigation into the nature of modifications of the parton distributions in the nucleus. Using data collected at the LHC in 2013, the ATLAS experiment will show results on the prompt J/psi and psi(2S) nuclear modification factors and the double ratio, psi(2S) divided by J/Psi in p-Pb divided by the same in p-p, in p-Pb collisions at 5.02 TeV. The charmonia states were reconstructed via the dimuon decay channel and the yield will be differentially presented in bins of transverse momentum, rapidity, and event activity.

    The production rates of heavy quarkonia in ion-ion collisions provide sensitive probes in the studies of the hot and dense matter formed in these collisions at high energies. However, a reference for understanding the behavior in the hot medium is necessary; p-A collisions open the possibility to study heavy quarkonia states in a smaller system of much lower average temperature. This is an important step in forming a baseline for understanding A-A collisions, as well as an investigation into the nature of modifications of the parton distributions in the nucleus. Using data collected at the LHC in 2013, we show results on the prompt J/{\\Psi} and {\\Psi}(2S) nuclear modification factors and the double ratio, {\\Psi}(2S) divided by J/{\\Psi} in p-Pb divided by the same in p-p, in p-Pb collisions at 5.02 TeV. The charmonia states were reconstructed via the dimuon decay channel and the yield is analyzed differentially in bins of transverse momentum, rapidity, and event activity.

A total of 224 air-cleaning specialists attended the conference. The United States and 12 foreign countries were represented, and the specialists were affiliated with government agencies, educational institutions, and all aspects of the nuclear industry, including utilities, architect engineers, equipment suppliers, and consultants. Several major topics were discussed, similar to areas covered at previous conferences: chemical processing off-gas cleaning; particulate filler developments, including filter testing, performance, and response to physical stress,adsorber testing and performance, including laboratory and in-place testing; waste management; system operation; codes and standards; and advanced nuclear power plants. The conference continued to provide an effective forum for direct interchange of information of both a practical and theoretical nature. International participation and interest continues, as evidenced by over 40% of the papers being sponsored by foreign interests and almost 20% of the attendees being from outside the United States. The potential for new, safer nuclear plants of an advanced design was an optimistic note during the conference. Regulatory authorities are playing a major role in providing guidance in the development of safety goals and other technical criteria for these new installations

    We present a new measurement of J/psi production in Pb-Pb collisions at 158 GeV/nucleon, from the data sample collected in year 2000 by the NA50 Collaboration, under improved experimental conditions with respect to previous years. With the target system placed in vacuum, the setup was better adapted to study, in particular, the most peripheral nuclear collisions with unprecedented accuracy. The analysis of this data sample shows that the (J/psi)/Drell-Yan cross-sections ratio measured in the most peripheral Pb-Pb interactions is in good agreement with the nuclear absorption pattern extrapolated from the studies of proton-nucleus collisions. Furthermore, this new measurement confirms our previous observations that the (J/psi)/Drell-Yan cross-sections ratio departs from the normal nuclear absorption pattern for semi-central Pb-Pb collisions and that this ratio persistently decreases up to the most central collisions.

    Long term tests of PSI membranes based on radiation-grafted FEP and ETFE films were carried out and FEP-based membranes were evaluated by monitoring the in-situ membrane area resistance measured by a current pulse method. By modifying our irradiation procedure and using the double crosslinking concept we obtain reproducible membrane cell lifetimes (in term of in-situ membrane resistance) of greater than 5000 hours at 60-65{sup o}C. Preliminary tests at 80-85{sup o}C with lifetimes of greater than 2500 demonstrate the potential long term stability of PSI proton exchange membranes based on FEP over the whole operating temperature range of low-temperature polymer electrolyte fuel cells. Radiation grafted PSI membranes based on ETFE have better mechanical properties than those of the FEP membranes. Mechanical properties are particularly important in large area cells and fuel cell stacks. ETFE membranes have been tested successfully for approximately 1000 h in a 2-cell stack (100 cm{sup 2} active area each cell). (author) 4 figs., 4 refs.

  1. Decays of J/psi (3100) to baryon final states

    We present results for the decays of psi(3100) into baryon and hyperon final states. The sample studied here consists of 1.3 million produced psi decays. The decays into nonstrange baryons agree well with currently established results, but with better statistics. In addition, significant resonance formation in multibody final states is observed. The decay psi → anti ppγ, the first direct photon decay of the psi involving baryons in the final state, is presented and the theoretical implications of the decays are briefly explored. Several new decays of the psi involving strange baryons are explored, including the first observations of three body final states involving hyperons. The I-spin symmetry of the strong decay psi → baryons has clearly been observed. The reduced matrix elements for psi → B anti B are presented for final states of different SU(3) content. The B 8 anti B 8 results are in excellent agreement with the psi being an SU(3) singlet as are the results for psi → B 10 anti B 10 . We present the first evidence for the SU(3) violating decays of the type psi → B 8 anti B 10 + c.c.. Angular distributions for psi → B 8 anti B 8 are presented and compared with theoretical predictions. Statistics are limited, but the data tends to prefer other than a 1 + Cos 2 theta distribution

    The inclusive production of the $\\psi$(2S) charmonium state was studied as a function of centrality in p-Pb collisions at the nucleon-nucleon center of mass energy $\\sqrt{s_{\\rm NN}}$ = 5.02 TeV at the CERN LHC. The measurement was performed with the ALICE detector in the center of mass rapidity ranges $-4.46psi$(2S) decay to a muon pair. The $\\psi$(2S) production cross section $\\sigma_{\\psi(\\rm 2S)}$ is presented as a function of the collision centrality, which is estimated through the energy deposited in forward rapidity calorimeters. The relative strength of nuclear effects on the $\\psi$(2S) and on the corresponding 1S charmonium state J/$\\psi$ is then studied by means of the double ratio of cross sections $[\\sigma_{\\psi(\\rm 2S)}/\\sigma_{\\rm J/\\psi}]_{\\rm pPb}/[\\sigma_{\\psi(\\rm 2S)}/\\sigma_{\\rm J/\\psi}]_{\\rm pp}$ between p-Pb and pp collisions, and by the values of the nuclear modification...

    The cross sections for inelastic photoproduction of J/{psi} and {psi}' mesons have been measured in ep collisions with the ZEUS detector at HERA, using an integrated luminosity of 468 pb{sup -1} collected in the period 1996-2007. The {psi}' to J/{psi} cross section ratio was measured in the range 0.55psi} cross sections were measured for 0.11 GeV. Theoretical predictions within the non-relativistic QCD framework including NLO colour-singlet and colour-octet contributions were compared to the data, as were predictions based on the k{sub T}-factorisation approach.

    Results from a detailed study using the Crystal Ball detector at the SLAC e + e - storage ring SPEAR of the inclusive photon spectra from 1.8 x 10 6 psi' and 2.2 x 10 6 J/psi decays are presented. Radiative transitions from the psi' to the chi/sub 2,1,0/ states are observed with photon energies of 126.0 +- 0.2 +- 4, 169.6 +- 0.3 +- 4, and 258.4 +- 0.4 +- 4 MeV and branching ratios B(psi'→γchi/sub 2,1,0/) = (8.0 +- 0.5 +- 0.7)%, (9.0 +- 0.5 +- 0.7)%, and (9.9 +- 0.5 +- 0.8)%, respectively. Values for the natural linewidths of the chi states are obtained: GAMMA(chi/sub 2,1,0/) = 0.8--4.9, <3.8, and 13--21 MeV, respectively (90% C.L.). Improved values are found for the branching ratios B(psi'→γeta/sub c/) = (0.28 +- 0.06)% and B(J/psi→γeta/sub c/) = (1.27 +- 0.36)%, and for the natural width GAMMA(eta/sub c/) = 11.5 +- 4.5 MeV

    Irradiation tests and post-irradiation examinations in the framework of JNC-PSI-NRG collaboration project will be performed in 2003-2005. Irradiation fuel pins will be fabricated by the middle of 2003. The fabrication procedure for irradiation fuel pins has been started in 2001. Several fabrication tests and qualification tests in JNC and PSI (Paul Scherrer Institute, Switzerland) have been performed before the fuel pin fabrication. According to the design assignment between PSI and JNC in the frame of this project, PSI should make a specification document for the fuel pellet, the sphere-pac fuel particles, the vipac fuel particles, and the fuel pin. JNC should make a fabrication drawing for irradiation pins. JNC has been performed the fuel design in cooperation with PSI and NRG (Nuclear Research and Consultancy Group, Netherlands). In this project, the pelletized fuel, the sphere-pac fuel, and the vipac fuel will be simultaneously irradiated on HFR (High Flux Reactor, Netherlands). This fabrication drawing has been made under the design assignment with PSI, and consists of the drawing of MOX pellet, thermal insulator pellet, pin components, fuel segments, and the constructed pin. The fabrication drawings were approved in October 2001, but after that, the optimization of specifications has been discussed and agreed among all partners. In this report, the revised fabrication drawings will be shown. Based on the commission of Plutonium Fuel Technology Group, Advanced Fuel Recycle Technology Division, this design work has been performed in Fuel Design and Evaluation Group, Plutonium Fuel Fabrication Division, Plutonium Fuel Center.

    It has long been recognized by the NRC Technical Staffs that estimating the quantity of radioactivity inhaled by an individual worker involved large uncertainties. General air samples usually produce concentrations lower than those in the workers Breathing Zone (BZ). NRC guides have recognized this problem by specifying air monitoring programs which sample the Breathing Zone or concentrations known to be higher than that actually inhaled. In addition the availability of suitable samplers to obtain BZ samples and the practicality of requiring their use was somewhat in question to the NRC technical staff. AN NRC development contract was issued to provide a detailed review of the technical aspects of the problems and recommendations for practical upgrade of federal guidance. This project accomplished a review of the nuclear industry experience and knowledge through a literature search, site visits to representative licensed facilities, telephone surveys of many others, laboratory testing of personal air samplers (lapel samplers) and aerosol diffusion experiments to verify key conclusions and assumptions

    Preliminary testing of dissolved air flotation (DAF) for wastewater treatment is presented. A combined coagulation-flocculation/DAF column system is used to remove oil and 60 Co from nuclear industry wastewater. In this work, operational conditions and coagulant/flocculant concentrations are optimized by varying pH. Determinations of air-solids ratio (G/S), retention time (θ), pressure (P), volume of depressurized air-water mixture (V), turbidity and 60 Co concentrations are reported. The effect of the treatment on the efficiency of separation of oily residues is also discussed. The results establish that the coagulant/flocculant system, formed by a modified polyamine (25 mgL -1 ) and a slightly cationic polyacrylamide (1.5 mgL -1 ), under specific operational conditions (pH = 7, mixing intensity Im 1 = 300 s -1 and Im 2 = 30 s -1 ), allowed the destabilization of colloidal matter, resulting in resistant flocs. It was concluded that by using G/S = 0.3, θ = 15 min, P = 620 kPa and V = 0.0012 m 3 , the greatest percentage removals of oil, turbidity, total cobalt and 60 Co were obtained. These preliminary results then show that dissolved air flotation represents a good alternative for treatment of nuclear industry wastewater contaminated with radionuclides. (author)

    The ALICE collaboration has made the first measurement at the LHC of J/$\\Psi$ photoproduction in ultra-peripheral Pb-Pb-collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV. The J/$\\Psi$ is identified via its dimuon decay in the forward rapidity region with the muon spectrometer for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 55 mub-1. The cross section for coherent J/$\\Psi$ production in the rapidity interval -3.6 < y < -2.6 is measured to be $d\\sigma^{coh}_{J/\\Psi}/dy = 1.00 \\pm 0.18 (stat) ^{+0.24}_{-0.26}$ (syst) mb. The result is compared to theoretical models for coherent J/$\\Psi$ production and found to be in good agreement with models which include nuclear gluon shadowing.

    The decays B+-> J/psi 3 pi(+)2 pi(-) and B+ -> psi(2S)pi(+)pi(+)pi(-) are observed for the first time using a data sample corresponding to an integrated luminosity of 3.0 fb(-1), collected by the LHCb experiment in proton- proton collisions at the centre-of-mass energies of 7 and 8 TeV. The branching fractions relative to that of B+ -> psi(2S)K+ are measured to be B(B+-> J/psi 3 pi(+)2 pi(-))/B(B+ -> psi (2S)K+) = (1.88 +/- 0.17 +/- 0.09)x10(-2). B(B+ -> psi(2S)pi(+)pi(+)pi(-))/B(B+ -> psi (2...

  13. Forward production of J//psi/ in hadronic interactions and calibration of a large BGO electromagnetic calorimeter

    In the first part of this thesis, we describe an analysis of J//psi/ produced in the forward direction in the reaction πN → μ + μ/sup /minus//X. The data for this analysis were collected by Fermilab experiment E615. We measured the cross section for J//psi/ production and the angular distribution of muons from J//psi/ decay. We found evidence for longitudinal polarization of J//psi/ produced in the kinematic limit where the J//psi/ carries a large fraction of the incident pion's longitudinal momentum. This is the first experimental observation of longitudinal polarization of J//psi/ produced in hadronic interactions. In the second part of this thesis, we describe the construction and calibration of a large Bismuth Germanante (BGO) electromagnetic calorimeter designed to study e + e/sup /minus// collisions at center-of-mass energies near the Z 0 mass. The calorimeter is a subdetector of the L3 detector and will be installed in the Large Electron Positron collider (LEP) of the European Organization for Nuclear Research. We present the results of a calibration of the calorimeter in an electron test beam at electron energies of 2, 10, and 50 GeV. We show that the accuracy of the calibration is 0.8% at 2 GeV, improving to better than 0.5% at 10 GeV and above. 65 refs., 72 figs., 21 tabs

    This paper describes the major issues that impacted the organization and structure of a project for developing a comprehensive non- radiological air emissions inventory for a nuclear weapons facility. The major issues addressed paralleled the development of the inventory project and fall into the following categories: (1) defining the scope of work, (2) developing and managing the air emission inventory project, and (3) field investigations and evaluating operations for air emissions. This paper also describes the lines of communication that were established with state regulators to resolve problems and develop a successful working relationship. This paper illustrates a means to complete a complex air emission inventory with proper organization and cooperation with regulatory agencies. Further, it indicates the need of critical evaluation of project tasks to evaluate their impact on project schedule; it provides a method for implementing a quality assurance program that audits all phases of the emission survey; and it demonstrates a way of effectively managing outside contractors to meet schedule requirements and assure a high quality product. This paper is of value to those undertaking a similar complex air emission survey. 2 refs

  15. Aging and service wear of air compressors and dryers in nuclear power plants

    Compressed air systems and their associated compressors and dryers as incorporated in LWR power plants usually are not classified as safety related systems and components because their continued operation is not required to bring the plant to a safe shutdown condition. However, control air is a vital requirement for maintaining stable plant operation and its loss often results in a reactor trip and, on occasion, the actuation of engineered safety feature systems. Concerns caused by repeated instances of failures in air systems resulted in the high-priority ranking of Generic Issue No. 43, ''Reliability of Air Systems'' by the NRC. In support of the Nuclear Plant Aging Research (NPAR) Program, the Oak Ridge National Laboratory is carrying out a Phase I aging assessment of air compressors and dryers used in LWR power plants. The objectives of this study include: (1) determination of the types and ratings of equipment utilized in typical plants; (2) identification of aging and service wear stressors imposed on the machines; (3) evaluation of operating experience with the machines; (4) comparison of user and manufacturer-recommended inspection, surveillance, and monitoring (ISM) methods; and (5) the identification of any improved ISM methods that might lead to longer, more reliable, service. 2 refs

    The ALICE Collaboration has studied the inclusive production of the charmonium state $\\psi(2S)$ in proton-lead (p-Pb) collisions at the nucleon-nucleon centre of mass energy $\\sqrt{s_{NN}}$ = 5.02 TeV at the CERN LHC. The measurement was performed at forward ($2.03 < y_{cms} < 3.53$) and backward ($-4.46 < y_{cms} < -2.96$) centre of mass rapidities, studying the decays into muon pairs. In this paper, we present the inclusive production cross sections $\\sigma_{\\psi(2S)}$, both integrated and as a function of the transverse momentum $p_{T}$, for the two $y_{cms}$ domains. The results are compared to those obtained for the 1S vector state (J/$\\psi$), by showing the ratios between the production cross sections, as well as the double ratios $[\\sigma_{\\psi(2S)}/\\sigma_{J/\\psi}]_{pPb}/[\\sigma_{\\psi(2S)}/\\sigma_{J/\\psi}]_{pp}$ between p-Pb and proton-proton collisions. Finally, the nuclear modification factor for inclusive $\\psi(2S)$ is evaluated and compared to the measurement of the same quantity for J...

    The application of spectrometric methods of nuclear techniques to the investigations of atmospheric air pollution by toxic and radioactive elements and results of these investigations conducted in the highly industrialized and urbanized regions of Poland have been presented. The method of precipitation of the samples, the measurements and analysis of radiation spectra of alpha and gamma radiation emitted by isotopes present in the samples have been described. The concentrations of toxic metal dust in the air have been evaluated by neutron activation and X-ray fluorescence analysis. Appropriate methods of measurement, calibration of instrument and the discussion of results have been presented. The work presents the results of investigations performed in Siersza within the years 1973-1974 and in Warsaw in the period of 1975-1977, which have permitted to estimate the mean monthly values of concentration in the atmospheric air of the following radioisotopes: 7 Be, 54 Mn, 95 Zr, 103 Ru, 106 Ru, 125 Sb, 131 I, 137 Cs, 140 Ba, 141 Ce, 144 Ce, 226 Ra, Th-nat, U-nat and the following stable elements: Sc, Cr, Fe, Co, Zn, As, Se, Sb, W, Pb. The analysis of changes in concentration of each particular artificial radioisotope in the air for the region of Poland in connection with Chinese nuclear explosions have been given. On the basis of the performed environmental investigations the method of analysis of relations between the concentrations of particular elements present in the dust has been discussed. The applications of this method have been presented. The hazard to the population and the environment caused by the radioactive and toxic dust present in the atmospheric air has been estimated.

  18. Review of failures in nuclear air cleaning systems (1975--1978)

    Moeller, D.W.

    1979-01-01

    During the period from January 1, 1975 through June 30, 1978, over 9,000 Licensee Event Reports (LERs) pertaining to the operation of commercial light water nuclear power plants in the US were reported to the Nuclear Regulatory Commission. Of these reports, over 1,200 (approximately 13%) pertained to failures in air monitoring, ventilating and cleaning systems. For BWR installations, over half of the reported events related to failures in equipment for monitoring the performance of air cleaning systems as contrasted to failures in the systems themselves. In PWR installations, failures in monitoring equipment amounted to about 32% of the total. Reported problem areas in BWR installations included the primary containment and standby gas treatment and off-gas systems, as well as the High Pressure Coolant Injection and Reactor Core Isolation Systems. For PWR installations, reported problem areas included primary containment and associated spray systems and waste processing equipment. Although data on reported failures in power reactor installations can be interpreted in a variety of ways, one message is clear. There is a need for research on the development of more reliable equipment for sampling and monitoring air systems. Equipment that provides inaccurate data on the performance of such systems can lead to as many problems as inadequacies in the systems themselves

  19. Compressed-air and backup nitrogen systems in nuclear power plants

    This report reviews and evaluates the performance of the compressed-air and pressurized-nitrogen gas systems in commercial nuclear power units. The information was collected from readily available operating experiences, licensee event reports, system designs in safety analysis reports, and regulatory documents. The results are collated and analyzed for significance and impact on power plant safety performance. Under certain circumstances, the fail-safe philosophy for a piece of equipment or subsystem of the compressed-air systems initiated a series of actions culminating in reactor transient or unit scram. However, based on this study of prevailing operating experiences, reclassifying the compressed-gas systems to a higher safety level will neither prevent (nor mitigate) the reoccurrences of such happenings nor alleviate nuclear power plant problems caused by inadequate maintenance, operating procedures, and/or practices. Conversely, because most of the problems were derived from the sources listed previously, upgrading of both maintenance and operating procedures will not only result in substantial improvement in the performance and availability of the compressed-air (and backup nitrogen) systems but in improved overall plant performance

  20. Charmonium spectroscopy from inclusive photons in J/psi and psi' decays

    1982-03-01

    Comparing our precise measurements for the E1 transitions psi' → γ chi/sub J/ with theory has underscored the importance of including (i) spin and relativistic corrections, (ii) variations in the 2P and 1S wave function shapes resulting from corrections, and (iii) coupling to closed and open decay channels. Considering our best measured total widths, i.e., GAMMA/sub tot/(eta/sub c) and GAMMA/sub tot(chi/sub o/), it appears that higher order QCD corrections are important and large. Our measurements for the E1 rates chi/sub J/ → γ J/sub psi/ suffer from the large errors in GAMMA/sub tot/(chi/sub J/); our best value is for GAMMA(chi/sub o/ → γ J/psi), and the agreement here is slightly better with the corrected theories. Both the potential models and the lowest order QCD derived predictions are capable of consistency with our observed HFS, although QCD radiative corrections appear to go in the wrong direction (less splitting than measured). For the best measured M1 allowed pseudoscalar transition, J/psi → γ eta/sub c/, the naive potential model and dispersion theory predictions are roughly a factor of 2 large. Perhaps corrections to the M1 formula are important

    In the course of nuclear power plant operation radioactive tritium is generated which is released to the environment as HTO via the exhaust air and the liquid effluents. Measurement and balancing of the tritium emissions are required in order to be able to evaluate the resulting radiation exposure of the population. For determination of the HTO emission the humidity of the measured air is absorbed at a rod shaped molecular sieve of 1/16'' mesh size. The desiccant is contacted with T-free water and the T activity concentration of the water is determined after 3 H/ 1 H isotope exchange. The rod shaped molecular sieves are suited for use under this method on account of their drying capacity largely independent of temperature and air humidity and the good handling capability. The detection limit is at 19 Bq HTO/m 3 air. The exhaust air from several 3 H-emitters of the Karlsruhe Nuclear Research Center was monitored by this method for its HTO content and the results were compared with the values measured at existing points of measurement. The good results have been the reason for the application of such collectors in the routine T-measurement performed within the framework of exhaust air monitoring on the site of the Karlsruhe Nuclear Research Center.

    Cross sections for elastic production of J/Psi mesons in photoproduction and electroproduction are measured in electron proton collisions at HERA using an integrated luminosity of 55 pb^{-1}. Results are presented for photon virtualities Q^2 up to 80 GeV^2. The dependence on the photon-proton centre of mass energy W_{gamma p} is analysed in the range 40 < \\Wgp < 305 GeV in photoproduction and 40 < \\Wgp < 160 GeV in electroproduction. The \\Wgp dependences of the cross sections do not change significantly with Q^2 and can be described by models based on perturbative QCD. Within such models, the data show a high sensitivity to the gluon density of the proton in the domain of low Bjorken x and low Q^2. Differential cross sections d\\sigma/dt, where t is the squared four-momentum transfer at the proton vertex, are measured in the range |t|<1.2 GeV^2 as functions of \\Wgp and Q^2. Effective Pomeron trajectories are determined for photoproduction and electroproduction. The J/Psi production and decay ang...

    Highlights: Black-Right-Pointing-Pointer Phi ({Phi}) and psi ({Psi}) angles determine sterile protective immunity. Black-Right-Pointing-Pointer Modified peptide's tendency to assume a regular conformation related to a PPII{sub L}. Black-Right-Pointing-Pointer Structural modifications in mHABPs induce Ab and protective immunity. Black-Right-Pointing-Pointer mHABP backbone atom's interaction with HLA-DR{beta}1{sup Asterisk-Operator} is stabilised by H-bonds. -- Abstract: Modified HABP (mHABP) regions interacting with HLA-DR{beta}1{sup Asterisk-Operator} molecules have a more restricted conformation and/or sequence than other mHABPs which do not fit perfectly into their peptide binding regions (PBR) and do not induce an acceptable immune response due to the critical role of their {Phi} and {Psi} torsion angles. These angle's critical role was determined in such highly immunogenic, protection-inducing response against experimental malaria using the conformers (mHABPs) obtained by {sup 1}H-NMR and superimposed into HLA-DR{beta}1{sup Asterisk-Operator }-like Aotus monkey molecules; their phi ({Phi}) and psi ({Psi}) angles were measured and the H-bond formation between these molecules was evaluated. The aforementioned mHABP propensity to assume a regular conformation similar to a left-handed polyproline type II helix (PPII{sub L}) led to suggesting that favouring these conformations according to their amino acid sequence would lead to high antibody titre production and sterile protective immunity induction against malaria, thereby adding new principles or rules for vaccine development, malaria being one of them.

    Optimization is one of the bases of radioprotection and aims to move doses away from the dose limit that is the borderline of acceptable radiological risk. The work aims to use the monitoring of the concentration of alpha emitters in the air as a tool of the optimization process. We analyzed 27 sampling points of airborne alpha concentration in a nuclear fuel cycle facility. The monthly averages were considered statistically different, the highest in the month of February and the lowest in the month of August. All other months were found to have identical mean activity concentration values. Regarding the sampling points, the points with the highest averages were points 12, 15 and 9. These points were indicated for the beginning of the optimization process. Analysis of the production of the facility should be performed to verify possible correlations between production and concentration of alpha emitters in the air

    The characteristics of different types of PML were analyzed and the convolutional PML was chosen to truncate the open boundaries in numerical simulation of nuclear electromagnetic pulse from air explosions. On the basis of the split-field PML and the plane-wave solution of electromagnetic field in free space, the unsplit-field PML was constructed. By applying the convolutional theorem of Fourier transform, the discrete iterative equations of electromagnetic field components were presented in the CPML media under the two-dimension prolate-spheroidal coordinate system. The numerical results indicate that the method of CPML can largely decrease calculation errors of boundary fields. (authors)

    The safety and process analyses of the proposed Integrated Process Strategy (IPS) to move the N-Reactor spent nuclear fuel (SNF) stored at K-Basin to an interim storage facility require information about the oxidation behavior of the metallic uranium. Limited experiments have been performed on the oxidation reaction of SNF samples taken from an N-Reactor outer fuel element in various atmospheres. This report discusses studies on the oxidation behavior of SNF using two independent experimental systems: (1) a tube furnace with a flowing gas mixture of 2% oxygen/98% argon; and (2) a thermogravimetric system for dry air oxidation

  12. Dose factors to calculate the radiation exposure due to radioactive waste air from nuclear facilities

    Brenk, H.D.; Vogt, K.J.

    1977-01-01

    An evaluation of the environmental impact of nuclear plants according to paragraph 45 of the Radiation Protection Directive of the Federal Republic of Germany requires the calculation of dose conversion factors indicating the correlation between the contaminated medium and individual radiation exposure. The present study is to be conceived as a contribution to discussion on this subject. For the determination of radiation exposure caused by the waste air of nuclear plants, models are being specified for computing the dose conversion factors for the external exposure pathways of β-submersion, γ-submersion and γ-radiation from contaminated ground as well as the internal exposure pathways of inhalation and ingestion, which further elaborate and improve the models previously applied, especially as far as the ingestion pathway is concerned, which distinguishes between 6 major food categories. The computer models are applied to those radionuclides which are significan for nuclear emitters, in particular nuclear light-water power stations. The results obtained for the individual exposure pathways and affected organs are specified in the form of tables. For this purpose, calculations were first of all carried out for the so-called 'reference man'. The results can be transferred to population groups with different consumption habits (e.g. vegetarians) by the application of correction factors. The models are capable of being extended with a view to covering other age groups. (orig.) [de

    Objective: To detect artificial radionuclide content in the spinach and soil in open air vegetable garden in Beijing during Fukushima nuclear accident and to study the radioactive contamination characteristics of the samples. Methods: 6 spinach samples and 3 soil samples in open air vegetable garden were obtained through continuously sampling. High-purity germanium (HPGe) γ spectrometry was used to analyze activity concentrations of artificial radionuclide 131 I etc in these samples. Results: Artificial radionuclide 131 I was detected in the 6 open air spinach samples. Artificial radionuclide 137 Cs was detected in 3 vegetable garden soil samples, trace amount of 131 I was detected in 1 open-air surface soil sample alone. Conclusions: Following the Fukushima nuclear accident, spinach in Beijing's open-air vegetable garden was slightly polluted by artificial radionuclide 131 I, with the highest values of pollution appeared around April 4, 2011, but it could not cause harm to human health.

    Indoor air quality effects on human health are of increasing concern to public health agencies and building owners. The prevention and treatment of 'sick building' syndrome and the spread of air-borne diseases in hospitals, for example, are well known priorities. However, increasing attention is being directed to the vulnerability of our public buildings/places, public security and national defense facilities to terrorist attack or the accidental release of air-borne biological pathogens, harmful chemicals, or radioactive contaminants. The Indoor Air Nuclear, Biological, and Chemical Health Modeling and Assessment System (IA-NBC-HMAS) was developed to serve as a health impact analysis tool for use in addressing these concerns. The overall goal was to develop a user-friendly fully functional prototype Health Modeling and Assessment system, which will operate under the PNNL FRAMES system for ease of use and to maximize its integration with other modeling and assessment capabilities accessible within the FRAMES system (e.g., ambient air fate and transport models, water borne fate and transport models, Physiologically Based Pharmacokinetic models, etc.). The prototype IA-NBC-HMAS is designed to serve as a functional Health Modeling and Assessment system that can be easily tailored to meet specific building analysis needs of a customer. The prototype system was developed and tested using an actual building (i.e., the Churchville Building located at the Aberdeen Proving Ground) and release scenario (i.e., the release and measurement of tracer materials within the building) to ensure realism and practicality in the design and development of the prototype system. A user-friendly "demo" accompanies this report to allow the reader the opportunity for a "hands on" review of the prototype system's capability.

  3. Aging assessment of nuclear air-treatment system HEPA filters and adsorbers

    Winegardner, W.K.

    1993-08-01

    A Phase I aging assessment of high-efficiency particulate air (HEPA) filters and activated carbon gas adsorption units (adsorbers) was performed by the Pacific Northwest Laboratory (PNL) as part of the US Nuclear Regulatory Commission's (NRC) Nuclear Plant Aging Research (NPAR) Program. Information concerning design features; failure experience; aging mechanisms, effects, and stressors; and surveillance and monitoring methods for these key air-treatment system components was compiled. Over 1100 failures, or 12 percent of the filter installations, were reported as part of a Department of Energy (DOE) survey. Investigators from other national laboratories have suggested that aging effects could have contributed to over 80 percent of these failures. Tensile strength tests on aged filter media specimens indicated a decrease in strength. Filter aging mechanisms range from those associated with particle loading to reactions that alter properties of sealants and gaskets. Low radioiodine decontamination factors associated with the Three Mile Island (TMI) accident were attributed to the premature aging of the carbon in the adsorbers. Mechanisms that can lead to impaired adsorber performance include oxidation as well as the loss of potentially available active sites as a result of the adsorption of pollutants. Stressors include heat, moisture, radiation, and airborne particles and contaminants

    Land-use changes (intensification, extensification and abandonment) in agriculture and forestry are considered to be the major driving forces for changes in ecosystem function and dynamics, and in landscape patterns in Europe. The aim of the EU project ECOMONT is to investigate the potential risks due to land-use change in the mountainous ecosystem. Fluxes of sensible and latent heat, water vapour, CO{sub 2} and pollutants between the vegetation and the atmosphere are sensitive and critical factors characterising landscape function. The Atmospheric Pollution Section of the PSI contributes to this project with the measurements of these fluxes. The measuring techniques, the experimental setup and first results are presented.

    Results on diffractive photoproduction of psi(2S) mesons are presented using data collected between 1996 and 2000 with the H1 detector at the HERA ep collider. The data correspond to an integrated luminosity of 77 pb^(-1). The energy dependence of the diffractive psi(2S) cross section is found to be similar to or possibly somewhat steeper than that for J/psi mesons. The dependences of the elastic and proton dissociative psi(2S) photoproduction cross sections on the squared momentum transfer t at the proton vertex are measured. The t-dependence of the elastic channel, parametrised as e^(bt), yields b_(el)^(psi(2S))=(4.31+-0.57+-0.46) GeV^(-2), compatible with that of the J/psi. For the proton dissociative channel the result b_(pd)^(psi(2S))=(0.59+-0.13+-0.12) GeV^(-2) is 2.3 standard deviations smaller than that measured for the J/psi. With proper account of the individual wavefunctions theoretical predictions based on perturbative QCD are found to describe the measurements well.

    The Department of Energy (DOE) has a major effort underway in dismantling nuclear weapons. In support of this effort we have been developing a workstation for removing the high explosive (HE) from nuclear warheads using hot sprays of dimethyl sulfoxide (DMSO) solvent to dissolve the HE. An important component of the workstation is the air cleaning system that is used to contain DMSO aerosols and vapor and radioactive aerosols. The air cleaning system consists of a condenser to liquefy the hot DMSO vapor, a demister pad to remove most of the DMSO aerosols, a high efficiency particulate air (HEPA) filter to remove the remaining aerosols, an activated carbon filter to remove the DMSO vapor, and a final HEPA filter to meet the redundancy requirement for HEPA filters in radioactive applications. The demister pad is a 4{double_prime} thick mat of glass and steel fibers and was selected after conducting screening tests on promising candidates. We also conducted screening tests on various activated carbons and found that all had a similar performance. The carbon breakthrough curves were fitted to a modified Wheeler`s equation and gave excellent predictions for the effect of different flow rates. After all of the components were assembled, we ran a series of performance tests on the components and system to determine the particle capture efficiency as a function of size for dioctyl sebacate (DOS) and DMSO aerosols using laser particle counters and filter samples. The pad had an efficiency greater than 990% for 0.1 {mu}m DMSO particles. Test results on the prototype carbon filter showed only 70% efficiency, instead of the 99.9% in small scale laboratory tests. Thus further work will be required to develop the prototype carbon filter. 7 refs., 18 figs., 10 tabs.

    To find out the leak characteristic of research reactor 'HANARO' building in a typhoon condition MELCOR code which normally is used to simulate severe accident behavior in a nuclear power plant was used to simulate the leak rate of air and fission products from reactor hall after the shutdown of the ventilation system of HANARO reactor building. For the simulation, HANARO building was designed by MELCOR code and typhoon condition passed through Daejeon in 2012 was applied. It was found that the leak rate is 0.1%·day{sup -1} of air, 0.004%·day{sup -1} of noble gas and 3.7×10{sup -5}%·day{sup -1} of aerosol during typhoon passing. The air leak rate of 0.1%·day can be converted into 1.36 m{sup 3}·hr{sup -1} , but the design leak rate in HANARO safety analysis report was considered as 600 m3·hr{sup -1} under the condition of 20 m·sec{sup -1} wind speed outside of the building by typhoon. Most of fission products during the maximum hypothesis accident at HANARO reactor will be contained in the reactor hall, so the direct radiation by remained fission products in the reactor hall will be the most important factor in designing emergency preparedness for HANARO reactor.

  9. Design of off-gas and air cleaning systems at nuclear power plants

    International Nuclear Information System (INIS)

    1987-01-01

    The primary purpose of this report is to describe the current design of air and process off-gas cleaning technologies used in nuclear power plants (NPPs). Because of the large inventory of fission products that are produced in the fuel (i.e. in the range of 5x10 19 Bq per GW(e)·a) and the highly restrictive airborne radionuclide release limits being established by Member States, air and process off-gas cleaning technologies are constantly being improved to provide higher airborne radionuclide recovery efficiencies and a smaller probability of malfunction. For various technologies considered an attempt has been made to provide the following information: (a) Process description in terms of principles of off-gas and air cleaning, operating parameters and system performance; (b) Design for normal and accident situations; (c) Design of components with regard to construction materials, size, shape and geometry of the system, resistance to chemical and physical degradation from the operational environment, safety and quality assurance requirements

  10. Air particulate pollution studies in Asian countries using nuclear analytical techniques

    1998-01-01

    Air particulate pollution is regarded as critical in Asian cities. The levels of suspended particulate matter in major Asian cities far exceed the WHO's guideline. Nuclear analytical techniques have been widely used in the studies of air particulate pollution to provide aerosol elemental compositions for the purpose of deriving the structure of emission sources. This paper presents some preliminary observations and findings based on publications in scientific literatures. Data on PM-10 levels and socio-economic indicators are used for searching a relationship between air quality and the level of development across Asia. An inverse linear relationship between PM-10 levels and logarithm of per capita GDP appears to exist, although there are large fluctuations of data caused by the very different climatic and geographical conditions of cities studied. Soil dust is generally a major, or even predominant aerosol source in Asian cities. Other common sources include vehicular emissions, coal and oil combustion, burning of refuse (in open) and biomass (including forest fires). The relevance and the trends of these sources in Asian context are discussed. Multivariate receptor modelling techniques applied in source characterization are illustrated through the cases of Lahore and Hochiminh City. Although having limitations in dealing with mixing and overlapping sources, receptor modelling based on principal component factor analysis has been proven to be uncomplicated and sufficiently reliable for characterising aerosol sources in urban areas.

    Thermal diffusivity (TD) of p-Si and Ag/p-Si samples were measured by photoacoustic technique using open photoacoustic cell (OPC). The samples were annealed by heating them at 960, 1050, 1200, and 1300 °C for 3 h in air. The thermal diffusivity of Ag-coated samples was obtained by fitting the photoacoustic experimental data to the thermally thick equation for Rosencwaig and Gersho (RG) theory. For the single layer samples, the thermal diffusivity can be obtained by fitting as well as by obtaining the critical frequency f c . In this study, the thermal diffusivity of the p-Si samples increased with increasing the annealing temperature. The thermal diffusivity of the Ag/p-Si samples, after reaching the maximum value of about 2.73 cm2/s at a temperature of 1200 °C, decreased due to the silver complete melt in the surface of the silicon.

    This report was produced under the Detection of Defects and Degradation Monitoring of Nuclear Plant Safety Equipment element of the Nuclear Plant Aging Research Program. This element includes the identification of practical and cost-effective methods for detecting, monitoring, and assessing the severity of time-dependent degradation (aging) of control and service air compressors and dryers in nuclear power plants. These methods are to provide capabilities for establishing degradation trends prior to failure and developing guidance for effective maintenance. The topics of this Phase 1 assessment report are failure modes and causes resulting from aging, manufacturer--recommended maintenance and surveillance practices, and measurable parameters (including functional indicators) for use in assessing operational readiness, establishing degradation trends, and detecting incipient failure. the results presented are based on information derived from operating experience records, manufacturer-supplied information, and input from plant operators. For each failure mode, failure causes are listed by subcomponent, and parameters potentially useful for detecting degradation that could lead to failure are identified. 13 refs., 9 figs., 16 tabs

    Nuclear graphite endures gas oxidation in High Temperature Gas-cooled Reactor (HTGR), which may threaten the safety of reactor. To study the oxidation behavior of nuclear graphite, weight loss curve is usually measured through Thermo Gravimetric Analysis (TGA) method. In this work, three brands of nuclear graphite for HTGR (i.e., HSM-SC, IG-11, and NBG-18) are oxidized under 873 and 1073 K in open air, and their weight loss curves are obtained. The acceleration of oxidizing rate is observed for both HSM-SC and IG-11, and is attributed to the large porosity increase during oxidation process. For HSM-SC, the porosity increase comes from preferential binder oxidation, and thus its binder quality shall be improved to obtain better oxidation resistance. Temperature effects on oxidation for HSM-SC are also studied, which shows that oxidizing gas tends to be exhausted at graphite surface at high temperature instead of penetrate into the interior of bulk.

    After the Indiana Supreme Court ruled last November that the utility may not recover its investment from the cancelled plant, Public Service Indiana (PSI) decided to write off a substantial portion of the $2.7 million already invested in the cancelled Marble Hill nuclear plant. The board will omit common stock dividends for three years and the preferred stock dividend for the first quarter. It will also accept a negotiated rate settlement of 8.2% increase. A 5% emergency surcharge will become permanent. The settlement calls for the utility to restrict capital expenditures over the next three years to the $285.1 million already budgeted for construction. Opposition from a consumers group argues that ratepayers should not be the risk bearers for PSI, but the utility argues that its long-term financial health depends on attracting and keeping investors

    The main aim of research is to investigate the physical features of spatial distribution of the adsorbed chemical elements and their isotopes in the granular filtering medium in the iodine air filters of the type of AU-1500 in the forced-exhaust ventilation at the nuclear power plant. The ?-activation analysis method is applied to accurately characterize the distribution of the adsorbed radioactive chemical elements and their isotopes in the granular filtering medium in the AU-1500 iodine air filter after its long term operation at the nuclear power plant. The typical spectrum of the detected chemical elements and their isotopes in the AU-1500 iodine air filter, which was exposed by the irradiation of bremsstrahlung gamma-quantum producing by the accelerating electrons in the tantalum target, are obtained. The spatial distributions of the detected chemical element 127 I and some other chemical elements and their isotopes in the layer of absorber, which was made of the cylindrical coal granules of the type of SKT-3, in the AU-1500 iodine air filter are also researched. The possible influences by the standing wave of air pressure in the iodine air filter on the spatial distribution of the chemical elements and their isotopes in the iodine air filter are discussed. The comprehensive analysis of obtained research results on the distribution of the adsorbed chemical elements and their isotopes in the absorber of iodine air filter is performed.

    The ventilation and air cleaning system in the nuclear or radiological installations is one of the essential nuclear safety concerns. It is responsible for confining the radioactive materials involved behind suitable barriers during normal and abnormal conditions. It must be designed to prevent the release of harmful products (radioactive gases, or airborne radioactive materials) from the system or facility, impacting the public or workers, and doing environmental damage. There are two important safety functions common to all ventilation and air cleaning system in nuclear facilities. They are: a) the requirements to maintain the pressure of the ventilated volume below that of surrounding, relatively non-active areas, in order to inhibit the spread of contamination during normal and abnormal conditions, and b) the need to treat the ventilated gas so as to minimize the release of any radioactive or toxic materials. Keeping the two important safety functions is achieved by applying the fire protection for the ventilation system to achieve safety and adequate protection in nuclear applications facilities during fire and accidental criticality conditions.The main purpose of this research is to assist ventilation engineers and experts in nuclear installations for safe operation and maintaining ventilation and air cleaning system during fire accident in nuclear facilities. The research focuses on fire prevention and protection of the ventilation systems in nuclear facilities. High-Efficiency particulate air (HEPA) filters are extremely susceptible to damage when exposed to the effects of fire, smoke, and water; it is the intent of this research to provide the designer with the experience gained over the years from hard lessons learned in protecting HEPA filters from fire. It describes briefly and evaluates the design safety features, constituents and working conditions of ventilation and air cleaning system in nuclear and radioactive industry.This paper provides and

    The broad objective of this analysis was to provide risk-based information to help focus regulatory actions related to Instrument Air (IA) systems at operating nuclear power plants. We first created an extensive data base of summarized and characterized IA-related events that gave a qualitative indication of the nature and severity of these events. Additionally, this data base was used to calculate the frequencies of certain events, which were used in the risk analysis. The risk analysis consisted of reviewing published PRAs and NRC Accident Sequence Precursor reports for IA-initiated accident sequences, IA interactions with frontline systems, and IA-related risk significant events. Sensitivity calculations were performed when possible. Generically, IA was found to contribute less to total risk than many safety systems; however, specific design weaknesses in safety systems, non-safety systems, and the IA system were found to be significant in risk. 22 refs., 13 figs., 24 tabs

    In a very high temperature reactor (VHTR), graphite will be used not only for as a moderator and reflector but also as a major structural component due to its excellent neutronic, thermal and mechanical properties. In the VHTR, wear of graphite components is inevitable due to a neutron irradiation-induced dimensional change, thermal gradient, relative motions of graphite components and a shock load such as an earthquake. Large wear particles accumulated at the bottom of a reactor can influence the cooling of the lower part and small wear particles accumulated on the primary circuit and heat exchanger tube can make it difficult to inspect the equipment, and also decrease the heat exchange rate. In the present work, preliminary wear tests were performed at room temperature in ambient air environment to understand the basic wear characteristics of selected nuclear grade graphites for the VHTR

    The Proceedings of the sixteen conferences comprise a vertible encyclopedia on the technology of nuclear air and gas treatment and the control of airborne nuclear waste. These Proceedings cover the history of the technology; describe most of the research and developments in the field, worldwide, since the early 1950's; describe the problems that have been encountered and the solutions found to those problems; and summarize experience with equipment and systems developed for the control of airborne radioactive wastes in laboratory, radiochemical, and reactor operations, both government and commercial. The problem with this encyclopedia is that there has been no index to it; there has been no easy way for searching it to find what was available. This index fills the gap. The first conference was an informal meeting of a number of interested parties from among the then AEC contractors. Consequently, there were no proceedings for that meeting. The subsequent conferences, with their years, locations, and Proceedings numbers, are listed. This index consists of three parts: a tabulation of papers and their authors by paper number (Part I); a tabulation of papers and their paper numbers by author (Part II); and a key-word-in context (KWIC) index of papers. The paper number is a two-part designation consisting of the number of the conference (2, 3...16) followed by the page number of the paper in the corresponding Proceedings. The author index lists each author who has participated in the air cleaning conferences over the years, and the paper index lists all authors of the respective papers. The KWIC index is, in effect, a comprehensive subject cross index; each paper is listed as many times, by keyword, as there are major terms (i.e., keywords) in its title. Although this multiple listing results in a lengthy list, it provides a very deep cross-indexing of the papers

    In this study, air sampling locations in the stack of the Advanced Fuel Science Building (AFSB) at the Korea Atomic Energy Research Institute (KAERI) were assessed according to the ANSI/HPS N13.1-1999 specification. The velocity profile, flow angle and 10 μm aerosol particle profile at the cross-section as functions of stack height L and stack diameter D (L/D) were assessed according to the sampling location criteria using COMSOL. The criteria for the velocity profile were found to be met at 5 L/D or more for the height, and the criteria for the average flow angle were met at all locations through this assessment. The criteria for the particle profile were met at 5 L/D and 9 L/D. However, the particle profile at the cross-section of each sampling location was found to be non-uniform. In order to establish uniformity of the particle profile, a static mixer and a perimeter ring were modeled, after which the degrees of effectiveness of these components were compared. Modeling using the static mixer indicated that the sampling locations that met the criteria for the particle profile were 5-10 L/D. When modeling using the perimeter ring, the sampling locations that met the criteria for particle profile were 5 L/D and 7-10 L/D. The criteria for the velocity profile and the average flow angle were also met at the sampling locations that met the criteria for the particle profile. The methodologies used in this study can also be applied during assessments of air sampling locations when monitoring stacks at new nuclear facilities as well as existing nuclear facilities.

    The primary objective of this investigation was to ascertain if a dynamic, self-cleaning particulate exclusion precleaner, designed for relatively large dust removal (2 to 100+ {mu}m diameter particles) from helicopter turbine inlets, could be extended to submicron filtration. The improved device could be used as a prefilter for HEPA filtration systems, significantly increasing service life. In nuclear air cleaning, its use would reduce the amount of nuclear particulate matter that would otherwise be entrapped in the HEPA filter cartridge/panel, causing fouling and increased back pressure, as well as requiring subsequent disposal of the contaminated media at considerable expense. A unique (patent-pending) mechanical separation device has recently been developed to extract particulate matter from fluid process streams based on a proprietary concept called Boundary Layer Momentum Transfer (BLMT). The device creates multiple boundary layers that actively exclude particles from entering the perimeter of the device, while allowing air to traverse the boundaries relatively unimpeded. A modified two-dimensional (2-D) computerized flow simulation model was used to assist in the prototype design. Empirical results are presented from particle breakthrough and AP experiments obtained from a reduced-scale prototype filter. Particles larger than 0.23 {mu}m were actively excluded by the prototype, but at a higher pressure drop than anticipated. Experimental data collected indicates that the filter housing and the inlet flow configuration may contribute significantly to improvements in device particle separation capabilities. Furthermore, preliminary experiments have shown that other downstream pressure drop considerations (besides those just across the spinning filtration disks) must be included to accurately portray the AP across the device. Further detailed quantitative investigations on a larger scale (1,000 CFM) prototype are warranted. 3 refs., 5 figs., 2 tabs.

    Among nuclear and nuclear related analytical techniques, neutron activation analysis and X-ray fluorescence spectrometry proved to be particularly useful for environmental studies owing to their nondestructive character and multi element capability. This paper emphasizes their importance among other multielement analytical methods by discussing their specific role due to specific physics basis, quite different to other destructive non-nuclear methods, and by summarizing results obtained in several studies related to air pollution research, including analyses of airborne particulate matter, water samples, lichens and mosses.

    At the Paul Scherrer Institute (PSI), the Hot Laboratory was built in the years 1961 to 1963 in the former EIR in order to make scientific material analyses on highly radioactive material samples and to prepare diagnostic and therapeutically useful radioisotopes. The 1964 safety report with the request for the granting of the operational warrant was revised for the first time in 2004. Further safety reports and radiation protection plans were produced and accepted by the surveying authorities. The operational regulations were revised and approved on a yearly basis by the PSI direction. The regulations reflect the experience gained in 40 years of safe operation and take new regulations in nuclear energy legislation into account. In the years 2000-2002 the Hot Lab was refitted especially with respect to the fields of radiation and fire protection. Presently, the Hot Lab is used for applied material research on highly radioactive samples which mainly come from nuclear power plants, research reactors and the target stations of the PSI accelerator facilities. The investigations on highly radioactive samples and the handling of large quantities of radioisotopes include the possibility of incidents. The analysis of such incidents shows that the legal safety requirements are satisfied. The Swiss Federal Nuclear Safety Inspectorate (ENSI) requirements concerning the protection of personnel, population and environment, as well as the protection against fire, are fulfilled. In the Hot Lab the principle of barriers for the containment of radioactive materials is applied. Open radioactive sources are manipulated in depressurized cells. The air extracted from the cells is filtered before being released to the environment. In the building, the total amount of radioactive materials is limited in order to reduce the exposition of the population in normal operation as well as in case of incidents, and to avoid criticality accidents. Possible weaknesses in this concept can be shown

    Yeast SUP7' or SUP11 nonsense suppressors have no phenotypic expression in strains deficient in the isopentenylation of A37 in tRNA. Here we show that such strains spontaneously produce cells with a nonsense suppressor phenotype which is related to the cytoplasmically inherited determinant and manifests all the key features of the [PSI+] prion. A screen of a multicopy yeast genomic library for genes that inactivate the [PSI+]-related suppressor phenotype resulted in the isolation of the SSB1 gene. Moreover, we demonstrate that multicopy plasmid encoding the Ssb1 chaperone cures cells of the [PSI+] prion.

    The J/ psi production in Pb-Pb interactions induced by 158 GeV/c incident Pb ions is studied as a function of centrality, as estimated from the neutral transverse energy or, alternatively, from the very forward hadronic energy of the collision. The J/ psi yield exhibits a similar pattern with a first drop for mid-peripheral collisions and a steady decrease for the most central reactions. Conventional hadronic models axe unable to fairly reproduce this trend which finds a natural explanation in a deconfined quark-gluon phase scenario. The J / psi transverse momentum distributions and their dependence with centrality are also reviewed in this presentation. (20 refs).

    Assuming a generalised Drell-Yan type mechanism for hadronic PSI-production, the relative importance of the different possible contributions is estimated from the data. We find that about 80% of the pp → PSI X cross-section is due to gluons. Therefore, these data give some information on the gluon distribution G(x) in the proton. Assuming xG(x) approximately (1-x)sup(n), data restrict n to 4... 6, in agreement with dimensional counting rules. The energy dependence of sigma(anti p p → PSI X)/sigma(pp → PSIX) is predicted.

    This paper will continue the review of HVAC/NATS related LERS presented at past Air Cleaning Conferences by Dr. D. W. Moeller and his associates. The general approach and format are similar. LER abstracts from mid 1985 through 1987 were reviewed and those related to HVAC/NATS classified and analyzed. The categories were jointly developed by Dr. Moeller, Dr. Casper Sun and myself. In appropriate cases both primary and secondary categories fora problem are given. A basic listing by category and brief statistical review are presented. Additionally a number of categories are discussed in some detail. The categories chosen for specific review are intended to highlight particular problem areas. NUREG/CR-2000 License Event Report (LER) Compilation is the basis for the initial review and coding. In essentially all cases where an LER is classified as of interest the complete LER was obtained and reviewed in full. The intent of this paper is to provide a basis for the industry to document and analyze problem areas that require additional attention. It appears that about 15% of all LERS in the subject period are HVAC/NATS related. This figure is generally consistent with those reported at the 17th DOE Nuclear Air Cleaning Conference. It is hoped that such attention will allow additional resources to be allocated to upgrade systems, procedures and training as well as in some cases government regulation

    In the stack exhaust air of the nuclear power stations the portion of inorganic 131 I was, apart from 2 sampling periods, less than 50%. In the stack exhaust air of the research reactor the inorganic 131 I prevailed. The removal efficiency of the I 2 sorption materials DSM 11 and DSM 17 for 131 I in the form of CH 3 I and C 6 H 5 I was very low. 131 I in the form of C 6 H 5 I was removed by AC 6120 and LMS 13 X-Ag (Linde molecular sieve in the Ag form) to a very small extent too, by activated charcoal impregnated with KI or TEDA however to a very high extent. In the experiments concerning the preparation and removal of 131 I in the form of HIO an iodine species that was difficult to remove with AC 6120 was found which could be HIO. Its maximum portion in the carrier gas was 50%. (orig./RW) [de

    It was therefore necessary to implement a PC based software for the prediction of the radiological impact on the environment and on the population around the JRC Ispra site caused by any accident occurring at any nuclear facilities within the site. For this reason the SSRP unit has developed with other partners a specific decision PC based support tool, whose characteristics are described in this paper. The developed SW is the first implementation of GIS technology applied to an existing MS-DOS trademark model validated model for wind field definition, calculation of atmospheric dispersion and concentration of pollutants at receptors. The software has been designed as to be able to superimpose, for each point in an area of 50 km radius from the JRC Ispra, layers of information coming from customisable databases. The result is a user-friendly Windows trademark based software, able to quickly calculate and display values of ground and air radioactive contamination around JRC Ispra, following an accidental release of radioactive substances from within a JRC Ispra nuclear installation.

The repackaging procedures mandated that no plastics were permitted, all labels and tape were to be removed and the pins to be clean and inspected Loading of the fuel into the CCC/ISV package was permitted only if it was not raining or snowing. This was to preclude the introduction of any water The purpose was to minimize the presence of any hydrogenous material inside the storage vessels. The scope of NFPA 69, 'Standard on Explosion Prevention Systems', precludes its applicability for this case. The reactor fuel pins are helium bonded. The non-fuel pins, such as the pellet stacks, are also helium bonded. The fuel pellets were sintered at temperatures that preclude any residual hydrogenous material. Hydrogen gas can be formed from neutron and gamma radiolysis of water vapor. The radiolysis reaction is quite complex involving several intermediate radicals, and competing recombination reactions. Hydrogen gas can also be formed through corrosion. This analysis takes a simplistic approach and assumes that all water vapor present in the storage vessel is decomposed into hydrogen gas. Although the analysis is needed to specifically address HUFP storage of nuclear fuel, it is equally applicable to any sealed fuel storage vessel under the assumptions listed

    Highlights: • A benchmark exercise on stratification erosion in containment was conducted using a test in the PANDA facility. • Blind calculations were provided by nineteen participants. • Results were compared with experimental data. • A ranking was made. • A large spread of results was observed, with very few simulations providing accurate results for the most important variables, though not for velocities. - Abstract: The third International Benchmark Exercise (IBE-3) conducted under the auspices of OECD/NEA is based on the comparison of blind CFD simulations with experimental data addressing the erosion of a stratified layer by an off-axis buoyant jet in a large vessel. The numerical benchmark exercise is based on a dedicated experiment in the PANDA facility conducted at the Paul Scherrer Institut (PSI) in Switzerland, using only one vessel. The use of non-prototypical fluids (i.e. helium as simulant for hydrogen, and air as simulant for steam), and the consequent absence of the complex physical effects produced by steam condensation enhanced the suitability of the data for CFD validation purposes. The test started with a helium–air layer at the top of the vessel and air in the lower part. The helium-rich layer was gradually eroded by a low-momentum air/helium jet emerging at a lower elevation. Blind calculation results were submitted by nineteen participants, and the calculation results have been compared with the PANDA data. This report, adopting the format of the reports for the two previous exercises, includes a ranking of the contributions, where the largest weight is given to the time progression of the erosion of the helium-rich layer. In accordance with the limited scope of the benchmark exercise, this report is more a collection of comparisons between calculated results and data than a synthesis. Therefore, the few conclusions are based on the mere observation of the agreement of the various submissions with the test result, and do not

    It is proposed by a large community of PSI- and external scientists to install an electron cyclotron resonance (ECR) source for highly charged heavy ions at the PHILIPS (injector I) cyclotron. Such a facility would then allow to produce high intensity ion beams with energies up to 30 MeV/u. A workshop hold in June 1989 clearly showed that with such a machine a large variety of interesting heavy ion experiments could be performed. While at foreign heavy ion centres the main focus is given to basic research in the field of nuclear physics we propose to concentrate the scientific effort at a PSI heavy ion facility mainly onto applications in the fields of atomic physics, chemistry, accelerator mass spectrometry, radiation biology and solid state physics. This is adequate, in view of the broad infrastructure available at PSI together with the existing know-how in many different fields. The proposed machine will thus be of great potential use for a large community. (author) 19 figs., 3 tabs., 82 refs

    Exclusive $J/\\psi$ and $\\psi$(2S) vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured and are found to be in good agreement with results from previous experiments and theoretical predictions. The $J/\\psi$ photoproduction cross-section is reported as a function of the photon-proton centre-of-mass energy, and is shown to be consistent with measurements obtained at HERA with power law behaviour.

  6. Probabilistic reconstruction of internal exposure for nuclear power plant workers using air concentration measurements

    Air surveys, whole-body counting, bioassays or combination of these measurements can be utilized for purposes or assessing internal doses to determine compliance with occupational dose equivalent limits. Air sampling with a little support provided by whole body counting and/or bioassays was often relied on in dose calculations. The utility of air sampling for internal dose reconstruction is addressed in this paper through the probabilistic analysis of environmental factors and their impact on dose estimates. In this paper we attempt to reconstruct an internal dose due to inhalation of beta + gamma emitting radionuclides for a contractual electrician, Mr. X. The data available for reconstruction of internal dose for Mr. X was found to be highly variable and uncertain. Uncertainty describes a lack of knowledge about a parameter, this lack of knowledge theoretically can be reduced, e.g., if more measurements were to be taken (for example, estimated activities for alpha-emitting radionuclides are uncertain due to the influence of naturally-occurring alpha-emitters). Variability describes the existence of different values that represent different environmental conditions (for example, the air concentrations of radionuclides may vary over time because of the different tasks performed by workers in the area). Variability can not be reduced by additional data collection because the varying values reflect the variable nature of the environment, not a lack of data. The high variability in measured air concentrations in the restricted areas of a LWR nuclear power plant where he worked do not allow adequate reconstruction of his individual internal dose using deterministic methods and therefore probabilistic methods are desirable. The guidance for probabilistic assessment developed by the United States Environmental Protection Agency as well as recommendations of the National Council of Radiation Protection provide an adequate framework for probabilistic reconstruction of

    Inhalation of radioiodine-131 is the largest cause of internal dose to nuclear medicine workers. The concentration of radioiodine-131 in air is limited by the Derived Air Concentration (DAC) of 416.67 Bq/m3. In this study air monitoring shall be performed to measure the radioiodine-131 contaminant in air by sample collection and analysis. Air samples were drawn from areas where there is a potential for I-131 airborne radioactivity e.g. in the hot laboratory, radioiodine treatment rooms, radioactive waste collection areas and waste water treatment plant. A portable battery-operated air sampler, Gilian BDX II with carbon- impregnated cellulose filters was used for air sampling. The flow rate was adjusted to 3 liters per minute and the sampler run for 180 minutes. Iodine-131 radioactivity on filter was measured for 10 minutes by 2 NaI(Tl) gamma counters, Perkin Elmer Wallac Wizard 1480 (3''x3'') and Atomlab 950 PC (2''x2'') with and objective for inter comparison. Counting efficiency of the counters are 57 and 39 percent respectively. Agreeable results of I-131 radioactivity were obtained from both gamma counters. The mean I-131 concentrations measured by Wallac(Atomlab) were 31.59±16.31 (29.84±14.74) Bq/m 3 in radioiodine fume hood for treatment dose dispensing, 8.98±4.33 (7.58±5.10) Bq/m 3 in fume hood accommodated with a dose calibrator, 7.80±5.39 (7.54±5.04) Bq/m 3 in radioactive waste storage area, 0.03±0.54 (0.03±0.57) Bq/m 3 in patient waiting area, 2.94±3.60 (2.55±2.98) Bq/m 3 in hospital ward waste collection area and 0.03±0.01 (0.03±0.01) Bq/m 3 in the water treatment plant area. Radioiodine concentrations in patient's room increases linearly as the administered dose was increasing. Mean±SD of the measured concentrations were 11.63±9.30 (9.86±8.98) Bq/m 3 , 18.57±13.24 (17.35±12.33) Bq/m 3 and 31.90±22.32 (30.90±22.49) Bq/m 3 for the administered doses of 3.7, 5.55 and 7.4 Bq respectively.

    A study of the J/psi state of the charmomium (c antic state) was performed at the D.C.I. collider in Orsay with the DM2 detector. 9 millions of J/psi have been produced, corresponding to more than one half of the actual world statistics. The very simple mecanism of the e +- annihilation into baryon-antibaryon via the J/psi state, allows measurements of the gluon spin through the emitted baryon angular distribution. The analyse of the channels J/psi → p antip and Λ antiΛ, permits to obtain parameters for the angular distributions. These experimental values favour very clearly a vectorial gluon hypothesis, as postulated by the quantum Chromodynamics [fr

    During the period of testing from 1945 to 1962 at the territory of Semipalatinsk test site (STS) within the Degelen Mountains in tunnels, 209 underground nuclear explosions were produced. Many of the tunnels have seasonal water seepage in the form of streams, through which tritium migrates from the underground nuclear explosion (UNE) venues towards the surface. The issue of tritium contamination occupies a special place in the radioactive contamination of the environment. In this paper we assess the level and distribution of tritium in the atmospheric air of ecosystems with water seepage at tunnels № 176 and № 177, located on "Degelen" site. There has been presented general nature of tritium distribution in the atmosphere relative to surface of a watercourse which has been contaminated with tritium. The basic mechanisms were studied for tritium distribution in the air of studied ecosystems, namely, the distribution of tritium in the systems: water-atmosphere, tunnel air-atmosphere, soil water-atmosphere, vegetation-atmosphere. An analytical calculation of tritium concentration in the atmosphere by the concentration of tritium in water has been performed. There has experimentally obtained the dependence for predictive assessment of tritium concentrations in air as a function of tritium concentration in one of the inlet sources such as water, tunnel air, soil water, vegetation, etc.. The paper also describes the general nature of tritium distribution in the air in the area "Degelen". Copyright © 2012 Elsevier Ltd. All rights reserved.

    Nowadays air pollution, consequent reduction of Ozone layer's thickness and increase of UV radiations are included as the hazardous phenomenon, which confronts mankind with fundamental challenges. Increase of population, use of high living standards together with the consumption of fossil fuels for generations of electrical energy have increases air pollution at the global. scale. According to the carried out studies carried out in the three latest decades, alteration of atmospheric gases such as Ozone, dioxide azoth, dioxide sulphur, dioxide carbon, Methane, monoxide carbon and hydrocarbons have caused the appearance of water and air new forms of pollutions all over the world the harmful side effects resulted from air pollution on the respiratory systems and other cordial and blood vessels are well documented. Due to the air and water uncommon pollutions resulted from fossil fuels consumptions, use of nuclear power plants as a safe option can prevent several pollutants such as gases, poisoning metals and suspended elements or downpour of acidic rains in environment. In this article, it is tried difficulties and hazardous results of air pollution and resulted from consumption of fossil fuels, and discusses the effective role of nuclear energy studies in reduction of such pollutions

    Air quality has been monitored at selected areas in Jamaica using high volume samplers. The results obtained, showed elevated levels of aluminium in bauxitic areas and very high lead concentrations in urban areas, from 5 to 35 times greater than in rural areas. The lower throughput of the conventional air particulate samplers however, restricts the air quality and health assessment on a nation-wide scale. Biomonitoring offers a cost-effective alternative to air-quality assessment if appropriate indicator species are chosen. The epiphytic lower plants such as lichens and mosses have been used as indicators of regional air quality in several European countries and USA. However, there is not enough studies on lichens and mosses in tropical countries, probably due to the lower occurrence of these species, which cover only 8% of the world's land surface. In Jamaica the epiphytic higher plants, represented by the genus Tillandsia are widely distributed, which make them along with the lichens and mosses potential site-specific bioindicators of air quality. The IAEA Co-ordinated Research Project entitled 'Biomonitoring of Air Pollution in Jamaica Through Trace-Element Analysis of Epiphytic Plants Using Nuclear And Related Analytical Techniques' will address these needs of the country. The primary purpose of the present study was to develop specific bioindicators of atmospheric air pollution in Jamaica, which will provide baseline information for health hazards assessment

    Freeman, W.P.

    1993-01-01

    Ever since the publication of the NRC Information Notice No. 87-32: Deficiencies in the Testing of Nuclear-Grade Activated Charcoal, nuclear power facilities in the US have struggled in their efforts to open-quotes...review the information for applicability to their facilities and consider action, if appropriate ...close quotes as stated in the notice. The encouragement of resident NRC inspectors at some nuclear power facilities has prompted a variety of responses ranging from no change at all in testing requirements to contemplated changes in plant technical specifications. This confusion is the result of a couple factors. The first factor is the lack of a current revision to NRC Regulatory Guide 1.52, the basic document used in nuclear power plant technical specifications for the testing of engineered-safety feature (ESF) post accident air cleaning systems. The second factor is the standards that have been written since the last revision of Reg. Guide 1.52 which include two revision of ANSI N509 and N510, two revisions of RDT M16-1T, two version of ASTM D3803, two versions of ASTM D4069, and three versions of an SME code AG-1. Few of the standards and codes listed above are commensurate with each other and, thus, present a nearly insolvable maze to the HVAC engineer asked to upgrade adsorbent testing requirements following the standards. This paper describes the authors experience with a number of nuclear power facilities in their efforts to meet the requirements of the new standards of testing adsorbents from nuclear power plant air cleaning systems. The existing standards are discussed in light of the current state of the art for adsorbent testing of adsorbent media from nuclear air treatment systems. Test results are presented showing the impact of new test requirements on acceptance criteria when compared to the old test requirements and recommendations are offered for solution of this testing problem in the future. 12 refs., 5 tabs

    Nuclear Power Plant (NPP) radiological hazards due to accidental failure or deliberated attacks are of most concern due to their destructive and global consequences: large area contaminations, injuries, exposure to ionizing radiation (which can cause death or illness, depends on the levels of exposure), loss of lives of both humans and animals, and severe damage to the environment. Prevention of such consequences is of a global importance and it has led to the definition of safety & design guidelines, and regulations by various authorities such as IAEA, U.S. NRC, etc. The guidelines define general requirements for the integrity of a NPP’s physical barriers (such as protective walls) when challenged by external events, for example human induced explosion. A more specific relation to the design of a NPP is that its structures and equipment (reactor building, fuel building, safeguards building, diesel-generator building, pumping station, nuclear auxiliaries building, and effluent treatment building) must function properly: shutdown the reactor, removal of decayed heat, storage of spent fuel, and treatment and containment of radioactive effluents) under external explosion. It requires that the NPP’s structures and equipment resistance to external explosion should be analyzed and verified. The air blast loading created by external explosion, as well as its effects & consequences on different kinds of structures are described in the literature. Structural elements response to the air blast can be analyzed in general by a Single Degree of Freedom (SDOF) system that converts a distributed mass, loads, and resistance to concentrated mass, force, and stiffness located at a representative point of the structure's element where the displacements are the highest one. Proper shielding should be designed if the explosion blast effects are greater than the resistance capacity.External explosion effects should be considered within the Screening Distance Value (SDV) of the NPP

  17. \\psi (2S) enhancement in p-Pb collision as an indication of quark-gluon plasma formation at the Large Hadron Collider

    Proton-nucleus collisions serve as an important baseline for the understanding and interpretation of the nucleus-nucleus collisions. These collisions have been employed to characterize the cold nuclear matter effects at SPS and Relativistic Heavy-Ion Collider energies for the past several years, as it was thought that quark-gluon plasma (QGP) is not formed in such collisions. However, at the Large Hadron Collider (LHC), there seems a possibility that QGP is formed during proton-lead (p-Pb) collisions. In this work, we have derived an expression for gluon induced excitation of J/\\psi to \\psi (2S), using pNRQCD, and show that the relative enhancement of \\psi (2S) vis-à-vis J/\\psi , especially at high p T , gives further indication that the QGP is indeed formed in p-Pb collisions at the most central collisions at LHC energy. J/\\psi and \\psi (2S) suppression effects seen at ALICE are also qualitatively explained.

The measurement is performed with the ALICE detector in Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV in the rapidity range 2.5 < y < 4.0. The dependence of the J/$\\psi v_2$ on the collision centrality and on the J/$\\psi$ transverse momentum is studied in the range 0 $\\le p_T \\lt $10 GeV/c. For semi-central Pb-Pb collisions at $\\sqrt{s_{NN}}$ = 2.76 TeV, an indication of non-zero v2 is observed with a maximum value of v2 = 0.116 $\\pm$ 0.046(stat.) $\\pm$ 0.029(syst.) for J/$\\psi$ in the transverse momentum range 2 $\\le p_T \\lt$ 4 GeV/c. The elliptic flow measurement complements the previously reported ALICE results on the inclusive J/$\\psi$ nuclear modification factor and favors the scenario of a significant fraction of J/$\\psi$ production from charm quarks in a deconfined partonic phase.

  19. Effects of welding fumes on nuclear air cleaning system carbon adsorber banks

    Standard Technical Specifications for nuclear air cleaning systems include requirements for surveillance tests following fire, painting, or chemical release in areas communicating with the affected system. To conservatively implement this requirement, many plants categorize welding as a chemical release process, and institute controls to ensure that welding fumes do not interact with carbon adsorbers in a filter system. After reviewing research data that indicated welding had a minimal impact on adsorber iodine removal efficiency, further testing was performed with the goal of establishing a welding threshold. It was anticipated that some quantity of weld electrodes could be determined that had a corresponding detrimental impact on iodine removal efficiency for the exposed adsorber. This value could be used to determine a conservative sampling schedule that would allow the station to perform laboratory testing to ensure system degradation did not occur without a full battery of surveillance tests. A series of tests was designed to demonstrate carbon efficiency versus cumulative welding fume exposure. Three series of tests were performed, one for each of three different types of commonly used weld electrodes. Carbon sampling was performed at baseline conditions, and every five pounds of electrode thereafter. Two different laboratory tests were performed for each sample; one in accordance with ASTM 3803/1989 at 95% relative humidity and 30 degrees C, and another using the less rigorous conditions of 70% relative humidity and 80 degrees C. Review of the test data for all three types of electrodes failed to show a significant correlation between carbon efficiency degradation and welding fume exposure. Accordingly, welding is no longer categorized as a `chemical release process` at McGuire Nuclear Station, and limits on welding fume interaction with ventilation systems have been eliminated. 4 refs., 3 figs., 1 tab.

    The production of J/psi and psi' charmonium states in proton-nucleus interactions has been investigated by the NA50 experiment, at the CERN SPS. High statistics data sets were collected with collisions induced by 450GeV protons incident on Be, Al, Cu, Ag and W targets. The J/psi and psi' production cross-sections have been determined for each p-A system and their dependences on the nucleus size have been studied, leading to the so-called normal nuclear absorption. Comparing the two patterns we see that the nuclear absorption is stronger for the psi' than for the J/psi. Given the high statistics of the data samples, the x_F (or rapidity) differential cross-sections of the J/psi and psi' states have also been studied, for each of the target nuclei.

  1. Are the PSI'→etasub(c)γ, PSI''→etasub(c)γ decays due to the gluon admixture

    1980-01-01

    A new method for estimating the radiative transitions between the excited 1 - charmonium levels and etasub(c) is proposed. The method is based on quantum chromodynamics plus the hypothesis of local duality and makes no reference to the standard potential picture. It is argued that the psi'(3.698) → etasub(c)γ decay is essentially due to gluon admixture in the psi' wave function. The most native analysis yields approximately 0.15 keV for the psi' → etasub(c)γ decay width, five times smaller than preliminary experimental data. The experimental number for GITA(psi' → etasub(c)γ)=0.7 keV can be reproduced only at a price of introducing a rather large psi''(3.772) → etasub(c)γ amplitude, GITA(psi'' → etasub(c)γ) approximately 1 keV. As a byproduct, a reliable prediction for the rho → πγ decay rate, GITA(rho → πγ) approximately 70 keV, is obtained in good agreement with recent measurement

    After a brief presentation of the context of his works, i.e. the nuclear fuel, its behaviour in a nuclear reactor, and studies performed in high activity laboratory, the author more precisely presents its research topic: the behaviour of defective nuclear fuel in air. Then, he describes the researches performed in three main directions: firstly, the characterization and understanding of fission gas localisation (experimental localisation, understanding of the bubble forming mechanisms), secondly, the determination of mechanisms related to oxidation (atomic mechanisms related to UO 2 oxidation, oxidation of fragments of irradiated fuel, the CROCODILE installation). He finally presents his scientific project which notably deals with fission gas release (from UO 2 to U 3 O 7 , and from U 3 O 7 to U 3 O 8 ), and with further high activity laboratory experiments

    The measurement of the $J/\\psi$ production cross-section with the LHCb detector is presented. The cross-section is measured as a function of the $J/\\psi$ transverse momentum and rapidity, in the forward region. Contributions from prompt $J/\\psi$ and $J/\\psi$ from $b$ are measured separately. Prospects for measurements of the $J/\\psi$ polarisation with a full angular analysis are also shown.

  5. Comprehensive study of psi meson production. Progress report

    International Nuclear Information System (INIS)

    Jones, S.T.; Harms, B.C.

    1985-01-01

    Our first paper under this grant is a calculation of prompt lepton production in upsilon and toponium decay. The results should prove useful in identifying signals for charm or bottom production. Our work has led to some improvement in our understanding of psi production in hadronic interactions, although further work is needed. Attempts to explain the difference between experimental and theoretical rates of psi hadroproduction led to a study of quark-gluon scattering, which proved to have a negative impact on the theoretical cross section once a leading mass singularity was absorbed into the gluon distribution function. Our study of psi production in B meson decays has led to an improvement in the leading-log calculation of this rate, which gives a much more precise prediction of the decay rate. We have also calculated all first-order QCD corrections to this weak process. We are now completing a companion calculation of n/sub c/ production, for which there is presently no data. Dr. Harms and Dr. Cox have collaborated on an attempt to determine the dominant contribution to the difference sigma(pN → psi x) - sigma(anti pN → psi x). The lowest order process contributing to this difference (q anti q → psi GG) has been shown previously to be small. They have calculated the next order process (q anti q → G*G* → psi G) and have apparently uncovered a new example of the violation of the Bloch-Nordsieck mechanism in QCD. Our work outside the realm of QCD has included a new fit to the total pp and anti pp cross sections. Dr. Cox has also been pursuing the question of representations of extended (especially N=8) supersymmetry

  8. Radiative decays of the psi' to all-photon final states

    Lee, R.A.

    1985-05-01

    A sample of 1.8 x 10 6 produced psi's collected by the Crystal Ball detector at SPEAR is used to measure branching ratios of selected radiative psi' decays to non-charmonium states which decay into photons. A sample of 2.2 x 10 6 produced J/psi's is used to measure the same radiative decays from the J/psi. The ratios BR(psi' → γf)/BR(J/psi → γf) = 9 +- 3%, BR(psi' → γtheta)/BR(J/psi → γtheta) < 10% - 15%, BR(psi' → γeta)/BR(J/psi → γeta) < 1.8%, and BR(psi' → γeta')/BR(J/psi → γeta') < 2.6% have been obtained. (Upper limits are 90% confidence level. The upper limit for the radiative decay to the theta is uncertain due to the possible presence of an f' signal in the J/psi data). Assuming these decays proceed via the annihilation of the initial quark and antiquark to a photon and two gluons, these ratios are predicted by lowest order QCD to be the same as the ratio of leptonic branching ratios of the psi' and J/psi, or 12.0 +- 2.2%. There currently exists no compelling explanation for the discrepancy between the ratios measured for the last two decays and the theoretical expectation

    In recent years several regulations and standards for air quality and limits for air pollution were issued or are in preparation by the European Union, which have severe influence on the environmental monitoring and legislation in Austria. This chapter of the environmental control report of Austria gives an overview about the legal situation of air pollution control in the European Union and in specific the legal situation in Austria. It gives a comprehensive inventory of air pollution measurements for the whole area of Austria of total suspended particulates, ozone, volatile organic compounds, nitrogen oxides, sulfur dioxide, carbon monoxide, heavy metals, benzene, dioxin, polycyclic aromatic hydrocarbons and eutrophication. For each of these pollutants the measured emission values throughout Austria are given in tables and geographical charts, the environmental impact is discussed, statistical data and time series of the emission sources are given and legal regulations and measures for an effective environmental pollution control are discussed. In particular the impact of fossil-fuel power plants on the air pollution is analyzed. (a.n.)

    2008-01-01

    Full text of publication follows: In these work we report the current status of the Swiss project Multi-scale Modeling Analysis (MSMA), jointly financed by PSI and Swissnuclear. The project aims at addressing the multi-scale (down to nano-scale) modelling of convective boiling phenomena, and the development of physically-based closure laws for the physical scales appropriate to the problem considered, to be used within Computational Fluid Dynamics (CFD) codes. The final goal is to construct a new computational tool, called Parallel Simulator of Boiling phenomena (PSI-BOIL) for the direct simulation of processes all the way down to the small-scales of interest and an improved CFD code for the mechanistic prediction of two-phase flow and heat transfer in the fuel rod bundle of a nuclear reactor. An improved understanding of the physics of boiling will be gained from the theoretical work as well as from novel small- and medium scale experiments targeted to assist the development of closure laws. PSI-BOIL is a computer program designed for efficient simulation of turbulent fluid flow and heat transfer phenomena in simple geometries. Turbulence is simulated directly (DNS) and its efficiency plays a vital role in a successful simulation. Having high performance as one of the main prerequisites, PSIBOIL is tailored in such a way to be as efficient a tool as possible, relying on well-established numerical techniques and sacrificing all the features which are not essential for the success of this project and which might slow down the solution procedure. The governing equations are discretized in space with orthogonal staggered finite volume method. Time discretization is performed with projection method, the most obvious a the most widely used choice for DNS. Systems of linearized equation, stemming from the discretization of governing equations, are solved with the Additive Correction Multigrid (ACM). methods. Two distinguished features of PSI-BOIL are the possibility to

    Ratios of the {psi}' over the J/{psi} production cross sections in the dilepton channel for C, Ti and W targets have been measured in 920 GeV proton-nucleus interactions with the HERA-B detector at the HERA storage ring. The {psi}' and J/{psi} states were reconstructed in both the {mu}{sup +}{mu}{sup -} and the e{sup +}e{sup -} decay modes. The measurements covered the kinematic range -0.35{<=}x{sub F}{<=}0.1 with transverse momentum p{sub T}{<=}4.5 GeV/c. The {psi}' to J/{psi} production ratio is almost constant in the covered x{sub F} range and shows a slow increase with p{sub T}. The angular dependence of the ratio has been used to measure the difference of the {psi}' and J/{psi} polarization. All results for the muon and electron decay channels are in good agreement: their ratio, averaged over all events, is R{sub {psi}}{sub '}({mu})/R{sub {psi}}{sub '}(e)=1.00{+-}0.08{+-}0.04. This result constitutes a new, direct experimental constraint on the double ratio of branching fractions, (B'({mu}).B(e))/(B({mu}).B'(e)), of {psi}'' and J/{psi} in the two channels. (orig.)

  12. Analysing the Air: Experiences and Results of Long Term Air Pollution Monitoring in the Asia-Pacific Region Using Nuclear Analysis Techniques

    Atanacio, Armand J.

    2015-01-01

    Particles present in the air we breathe are now recognized as a major cause of disease and premature death globally. In fact, a World Health Organization (WHO) report recently ranked ambient air pollution as one of the top 10 causes of death in the world, directly contributing annually to around 3.7 million premature deaths worldwide 65% of which occurred in the Asian region alone. Airborne particulate matter (PM) can be generated from natural sources such as windblown soil or coastal sea-spray; as well as anthropogenic sources such as power stations, industry, vehicles and domestic biomass burning. At low concentration these fine pollution particles are too small to be seen by eye, but penetrate deep into our lungs and even our blood stream as our nose and throat are inefficient at filtering them out. At large concentrations, they can also have wider regional effects including reduced visibility, acid rain and even climate variability. The International Atomic Energy Agency (IAEA) in 2000, recognizing air pollution as a significant local, national and global challenge, initiated a collaborative air pollution study involving 14 countries across the greater Asia-pacific region from 2000 to 2015. This has amassed a database containing more than 14,000 data lines of PM mass concentration and the concentration of up to 40 elements using nuclear analytical techniques. It represents the most comprehensive and long-term airborne PM data set compiled to date for the Asia-Pacific region and as will be discussed, can be used to statistically resolve individual source fingerprints and their contributions to total air pollution using Positive Matrix Factorization (PMF). This sort of data necessary for implementing or reviewing the effectiveness of policy level changes aimed at targeted air pollution reduction. (author)

  13. J/{psi} production and decay at the Z resonance

    Energy Technology Data Exchange (ETDEWEB)

    Vikas, P

    1994-10-13

    In the Large Electron Positron collider (LEP) bunches of electrons and positrons are brought in collision. At a collision energy of 91.2 GeV the Z resonance is excited. The Z boson, the uncharged mediator of the weak force, decays into a particle and an antiparticle almost instantaneously. The probability that in this process heavy quarks charm-anticharm(c anti c) and bottom-antibottom(b anti b) are formed is {approx}12% and {approx}15% respectively. Thus, LEP provides an ideal environment to make precision measurements in the heavy quark sector. The data for this thesis was collected with the L3 detector from 1990-1992. L3 is one of the four experiments at LEP. The integrated luminosity collected by L3 in this period is 43.5 pb{sup -1}. The L3 detector was designed to measure e{sup +}e{sup -} collisions up to 200 GeV with special emphasis on high resolution measurements of photons, electrons and muons. The detector is installed within a magnet providing 0.5 T field. It consists of subdetectors to detect and measure the direction and momentum/energy of charged particles, electromagnetic particles, hadrons and muons. In this thesis the production of the 1{sup 3} S{sub 1} (the j/{psi} meson) and the 2{sup 3} S{sub 1} (the {psi}` meson) and the c anti c bound states are investigated. The leptonic decays of the two mesons (J/{psi}, {psi}`{yields}l{sup +}l{sup -}, l=e, {mu}) provide the cleanest signals of heavy quarks. In this thesis, the {psi}` and J/{psi} mesons have been tagged via their decay into a muon pair. From the invariant mass distribution of the {mu}{sup +}{mu}{sup -} pairs the branching ratio for J/{psi} production at the Z, Br(Z{sup 0}{yields}J/{psi}+X), was determined to be 4.0{+-}0.6(stat.){+-}0.4(sys.)x10{sup -3} while the branching ratio for {psi}` production at the Z is smaller than <2x10{sup -3}.

    Richman, J.D.

    1985-01-01

    An analysis of the production, decay, and quantum numbers of the iota(1440) in radiative J/psi decays is presented. The iota(1440), because of its large production in this OZI-suppressed channel, is considered a possible gluonic bound-state, or glueball. The data, 2.7 x 10 6 produced J/psi's, were obtained using the Mark III detector at the SPEAR e + e - storage ring. The spin-parity of the iota(1440) is independently determined to be O - using two decays modes, iota → K/sub s/ 0 K/sup +/-/π/sup -/+/ and iota → K + K - π 0 . Measurements of the iota mass, width, and branching fractions are obtained using iota → K/sub s/ 0 K/sup +/-/π/sup -/+/, iota → K + K - π 0 , and iota → K/sub s/ 0 K/sub s/ 0 π 0 . The double radiative channels J/psi α γX, X → γ+ Vector, where Vector = rho 0 , phi, omega are studied to probe the quark content of the object X. Measurements of the hadronic decays J/psi → phi-eta, omega-eta, and omegaπ 0 , as well as the observation of the isospin-violating decay J/psi → rho 0 eta, are presented

  16. Concurrency Models with Causality and Events as Psi-calculi

    Directory of Open Access Journals (Sweden)

    Håkon Normann

    2014-10-01

    Full Text Available Psi-calculi are a parametric framework for nominal calculi, where standard calculi are found as instances, like the pi-calculus, or the cryptographic spi-calculus and applied-pi. Psi-calculi have an interleaving operational semantics, with a strong foundation on the theory of nominal sets and process algebras. Much of the expressive power of psi-calculi comes from their logical part, i.e., assertions, conditions, and entailment, which are left quite open thus accommodating a wide range of logics. We are interested in how this expressiveness can deal with event-based models of concurrency. We thus take the popular prime event structures model and give an encoding into an instance of psi-calculi. We also take the recent and expressive model of Dynamic Condition Response Graphs (in which event structures are strictly included and give an encoding into another corresponding instance of psi-calculi. The encodings that we achieve look rather natural and intuitive. Additional results about these encodings give us more confidence in their correctness.

    We present a study of J/{psi} meson production in collisions of 26.7 GeV electrons with 820 GeV protons, performed with the H1-detector at the HERA collider at DESY. The J/{psi} mesons are detected via their leptonic decays both to electrons and muons. Requiring exactly two particles in the detector, a cross section of {sigma}(ep{yields}J/{psi}X)=(8.8{+-}2.0{+-}2.2) nb is determined for 30 GeV{<=}W{sub {gamma}p}{<=}180 GeV and Q{sup 2}< or {approx}4 GeV{sup 2}. Using the flux of quasi-real photons with Q{sup 2}< or {approx}4 GeV{sup 2}, a total photoproduction cross section of {sigma}({gamma}p{yields}J/{psi}X)=(56{+-}13{+-}14) nb is derived at an average W{sub {gamma}p}=90 GeV. The distribution of the squared momentum transfer t from the proton to the J/{psi} can be fitted using an exponential exp(-bvertical stroke tvertical stroke ) below avertical stroke tvertical stroke of 0.75 GeV{sup 2} yielding a slope parameter of b=(4.7{+-}1.9) GeV{sup -2}.

    Valid inter-comparisons of operating performance parameters among all members of the nuclear industry are essential for the implementation of continuous improvement and for obtaining credibility among regulators and the general public. It is imperative that the comparison of performances among different industry facilities be as accurate as possible and normalized to industry-accepted reference standards

    The J/$\\psi$ production in Pb-Pb interactions induced by 158 GeV/c incident Pb ions is studied as a function of centrality, as estimated from the neutral transverse energy or, alternatively, from the very forward hadronic energy of the collision. The J/$\\psi$ yield exhibits a similar pattern with a first drop for mid-peripheral collisions and a steady decrease for the most central reactions. Conventional hadronic models axe unable to fairly reproduce this trend which finds a natural explanation in a deconfined quark-gluon phase scenario. The J/$\\psi$ transverse momentum distributions and their dependence with centrality are also reviewed in this presentation. (20 refs).

    Exclusive $J/\\psi$ and $\\psi(2S)$ vector meson production has been observed in the dimuon channel using the LHCb detector. The cross-section times branching fractions to two muons with pseudorapidities between 2.0 and 4.5 are measured to be \\begin{equation*} \\sigma_{pp\\rightarrow J/\\psi (\\rightarrow \\mu^{+} \\mu^{-})} (2.0 <\\eta_{\\mu^{\\pm}}< 4.5) = 307 \\pm 21 \\pm 36~\\text{pb}, \\end{equation*} \\begin{equation*} \\sigma_{pp\\rightarrow \\psi(2S) (\\rightarrow \\mu^{+} \\mu^{-})} (2.0 <\\eta_{\\mu^{\\pm}}< 4.5) = 7.8 \\pm 1.3 \\pm 1.0~\\text{pb}, \\end{equation*} where the first uncertainties are statistical and the second are systematic. The measurements are found to be in good agreement with results from previous experiments and theoretical predictions. The $J/\\psi$ photoproduction cross-section has been measured as a function of the photon-proton centre-of-mass energy. The results are consistent with measurements obtained at HERA and confirm a similar power law behaviour for the photoproduction cross-se...

    For the experimental study on the air/water countercurrent flow limitation in Nuclear Reactors, were built at CDTN an acrylic test sections with the same geometric shape of 'hot leg' of a Pressurized Water Reactor (PWR). The hydraulic circuit is designed to be used with air and water at pressures near to atmospheric and ambient temperature. Due to the complexity of the CCFL experimental, the numerical simulation has been used. The aim of the numerical simulations is the validation of experimental data. It is a global trend, the use of computational fluid dynamics (CFD) modeling and prediction of physical phenomena related to heat transfer in nuclear reactors. The most used CFD codes are: FLUENT®, STAR- CD®, Open Foam® and CFX®. In CFD, closure models are required that must be validated, especially if they are to be applied to nuclear reactor safety. The Thermal- Hydraulics Laboratory of CDTN offers computing infrastructure and license to use commercial code CFX®. This article describes a review about CCFL and the use of CFD for numerical simulation of this phenomenal for Nuclear Rector. (author)

    We briefly review recent results which we have obtained in the study of J/psi+Z production at the LHC. Considering our NLO computation in the Colour Evaporation Model (CEM) as an upper theory limit for the single-parton-scattering contributions, we claim that the existing data set from ATLAS points at a dominant double-parton-scattering contribution with an effective cross section smaller than that for jet-related observables. As a side product of our analysis, we have computed, for the first time, the one-loop QCD corrections to the J/psi P_T-differential cross section in the CEM.
