Nuclear materials inventory-verification techniques for large split-table fast critical assemblies are being studied in this program. Emphasis has been given to techniques that minimize fuel handling in order to reduce facility downtime and radiation exposure to the inventory team. The techniques studied include drawer seals, autoradiography, and spectral index measurements. Two-drawer sealing techniques have been studied, and the relative strengths and weaknesses are pointed out. The rod-type locking mechanism would not disrupt the reactor cooling air flow or interfere with autoradiography but is more expensive to implement. Passive autoradiography was used in a ZPPR inventory to verify to a 93% confidence level that less than 8-kg plutonium was missing. The inventory was completed in four days by a five-member team with radiation exposures well within acceptable limits. Two autoradiographic film packages were developed to distinguish HEU from a DU matrix. The 30-mil pack requires an exposure between 4 and 16 hours and fits into most of the drawers. The 40-mil pack requires only a two-hour exposure but fits into less than half the drawers.

The fuel-pin modeling code LIFE-GCFR has been developed to predict the thermal, mechanical, and fission-gas behavior of a Gas-Cooled Fast Reactor (GCFR) fuel rod under normal operating conditions. It consists of three major components: thermal, mechanical, and fission-gas analysis. The thermal analysis includes calculations of coolant, cladding, and fuel temperature; fuel densification; pore migration; fuel grain growth; and plenum pressure. Fuel mechanical analysis includes thermal expansion, elasticity, creep, fission-product swelling, hot pressing, cracking, and crack healing of fuel; and thermal expansion, elasticity, creep, and irradiation-induced swelling of cladding. Fission-gas analysis simultaneously treats all major mechanisms thought to influence fission-gas behavior, which include bubble nucleation, resolution, diffusion, migration, and coalescence; temperature and temperature gradients; and fission-gas interaction with structural defects.

Nondestructive assay (NDA) methods, principally passive gamma measurements and active neutron interrogation, have been studied for their safeguards effectiveness and programmatic impact as tools for making inventories of highly enriched uranium fast critical assembly fuel plates. It was concluded that no NDA method is the sole answer to the safeguards problem, that each of those emphasized here has its place in an integrated safeguards system, and that each has minimum facility impact.

From abstract: "A thunderstorm during the evening of August 31 and the morning of September 1, 1978, caused flooding in a small area of South-central New Jersey. Maximum peaks of record occurred on the Upper Crosswicks Creek basin in the vicinity of Fort Dix, Wrightstown, and New Egypt. At New Egypt, high water crest elevations for Crosswicks Creek were approximately four feet higher than the previous maximum recorded on August 28, 1971.

This report was compiled at the Hanford Engineering Development Laboratory operated by Westinghouse Hanford Company, a subsidiary of Westinghouse Electric Corpoation, for the United States Department of Energy and the Nuclear Regulatory Commission, under DOE contract number DE-AC14-76FF02170 and NRC service request number TV-0176.

Post-test examinations were conducted to determine failure mechanisms, electrode morphologies, and in-cell corrosion of cell components, and to recommend appropriate design changes for improved cell performance and reliability. The reactive electrode materials required the design and construction of a special metallographic glovebox facility. Combinations of macro- and microscopic examinations determined that electrical short circuits were the predominant causes of cell failure. The major short circuit mechanism was extrusion of active material from one electrode and its subsequent contact with the opposing electrode (opposite polarity). Other mechanisms for short circuits included metallic deposits across separators, metallic deposits across the feed-through insulator (electrolyte leakage and corrosion), equipment malfunctions, cell assembly difficulties, etc. Post-test examinations confirmed that the short circuits were of mechanical origin; appropriate design changes were, therefore, recommended. Extensive microscopic examinations were conducted on both negative and positive electrodes to determine the morphology. Agglomeration of Li-Al was observed in the negative electrodes of most multi-plate cells. Examinations showed that the sulfides in the positive electrode remained as discrete particles in an electrolyte matrix. Also discussed are the results of post-test examinations to determine the following: lithium gradients in the negative electrodes, electrode expansion, materials distribution, copper deposition within electrode separators of …
