Grafoil applications on-plant  

International Nuclear Information System (INIS)

Presented in this report are the quantitative and qualitative aspects of the more than 5,800 applications of Grafoil on-plant. The subject all-graphite product was originally made by the Union Carbide Corporation. Its utilization in the forms of valve packing, gasketing and sealant tapes for leak repair and prevention on-plant since March 1970 is marked with typical zero-leak results. For all practical purposes, the successful results with Grafoil implementation indicate an unqualified control of leakage problems that began in 1967 with the V-11 and V-12 valves in the primary system of N Reactor. Meaningfully, the accruals of savings with existing and future applications shall continue to be incalculable in personnel exposure, maintenance, and capital. Inherent in the savings are the devised methodology and innovative developments coordinately employed in resolving the leak repair problems.

Lifetime and {ital g}-factor measurements of the 11{sup {minus}} isomer in {sup 92}Tc  

Energy Technology Data Exchange (ETDEWEB)

The half-life ({ital T}{sub 1/2}) and {ital g} factor of the 2002 keV 11{sup {minus}} isomer in the odd-odd nucleus {sup 92}Tc produced by the pulsed heavy-ion reaction {sup 68}Zn({sup 28}Si,{ital p}3{ital n}){sup 92}Tc have been measured using time differential perturbed angular distribution method. The measured {ital T}{sub 1/2} value is 3.15(20) ns. From the observed spin precession frequency {omega}{sub {ital L}} of a {sup 92}Tc recoil implanted into a ferromagnetic Ni host, we obtain the {ital g} factor to be 0.806(20). The measured value of the {ital g} factor is in good agreement with a shell model analysis carried out using {pi}({ital p}{sub 1/2}{ital g}{sub 9/2}) and {nu}({ital p}{sub 1/2}{ital g}{sub 9/2}) orbitals for the proton particles and neutron holes outside the {sup 88}Sr core. {copyright} {ital 1996 The American Physical Society.}

Neutron-hole strengths and core coupling in /sup 87/Sr via the /sup 88/Sr("3He,#alpha#)/sup 87/Sr reaction  

International Nuclear Information System (INIS)

Neutron-hole states in /sup 87/Sr were studied by means of the /sup 88/Sr("3He,#alpha#)/sup 87/Sr reaction at 36 MeV. Angular distribution measurements were carried out from 3"0 to 41"0 (lab) and analyzed with the zero-range distorted-wave Born approximation method. Spectroscopic factors have been determined for about 50 discrete levels in /sup 87/Sr located below 6 MeV excitation energy and for the three lowest isobaric analog states 2p(3/2, 1f(5/2, and 2p(1/2 observed around 11 MeV. Many l = 1 and l = 3 discrete levels are observed in the 3--6 MeV excitation energy range. In addition, a large part of the 1f-2p strength is found to lie in the higher-lying continuum up to 13 MeV (about 10% and 40% for the l = 1 and 3 contributions, respectively). The distribution of the 1f-2p neutron-hole strength is compared to previous data on neighboring nuclei /sup 89/Zr and /sup 91/Mo. In addition, angular distributions for some low-lying high-spin states in /sup 87/Sr are nicely reproduced by ...

High-Resolution Infrared Spectra of Bicyclo[1.1.1]pentane  

Energy Technology Data Exchange (ETDEWEB)

Infrared spectra of bicyclo[1.1.1]pentane (C5H8) have been recorded at a resolution (0.0015 cm-1) sufficient to resolve for the first time individual rovibrational lines. This initial report presents the ground state constants for this molecule determined from the detailed analysis of three of the ten infrared-allowed bands, v14(e?) at 540 cm-1, v17(a2?) at 1220 cm-1, v18(a2?) at 832 cm-1, and a partial analysis of the v11(e?) band at 1237 cm-1. The upper states of transitions involving the lowest frequency mode, v14(e?), show no evidence of rovibrational perturbations but those for the v17 and v18 (a2?) modes give clear indication of Coriolis coupling to nearby e? levels. Accordingly, ground state constants were determined by use of the combination-difference method for all three bands. The assigned frequencies provided over 3300 consistent ground state difference values, yielding the following constants for the ground state (in units of ...
