Abstract

The effectiveness of a neutron well correlation counter (NWCC) and a random driver (RD) for plutonium-containing item assay and loss detection has been studied. The items were 4" x 2" x 1/4" stainless steel-clad metal plates and 6" x 3/8" stainless steel-clad oxide rods, each in two types of containment. It was found that absorption by dummies increases one's chance of detecting substitution over the chance of detecting simple removal. In all the loss-detection tests, however, there was only one failure to detect a loss. The NWCC did not separate out (α,n) neutrons well enough that one could use a calibration made with plates to assay for rods. The RD was found to have minimal usefulness for the assay of irradiated plates.

Fast Critical Assembly Safeguards: NDA Methods for Highly Enriched Uranium (Summary Report, October 1978 - September 1979)

Technical Report Bellinger, F.; Winslow, G.

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. It was found that the 185-keV area, as determined with a NaI detector, was independent of highly-enriched uranium (HEU) plate irradiation history, though the random neutron driver methodsmore »« less

Sensitivity Analysis of an Experimental Breeder Reactor II Fuel Assembly

Journal Article Ryan, Emerald; Pope, Chad - Transactions of the American Nuclear Society

The Experimental Breeder Reactor II (EBR-II) was selected as a candidate for a reactor physics benchmark evaluation due to its unique features and capabilities. In connection with the benchmark evaluation, the goal of this work was to perform a sensitivity analysis. The EBR-II was a sodium cooled, pool type, metal fueled, fast spectrum reactor. EBR-II operated from 1964 through 1994. It had a maximum heat output of 62.5 MW which could produce 20 MW of electricity. The design of EBR-II consisted of 637 hexagonal shaped, removable assemblies. The assemblies were divided into three regions: the core, an inner blanket, andmore »« less
Development of a Safeguards Verification Method and Instrument to Detect Pin Diversion from Pressurized Water Reactor (PWR) Spent Fuel Assemblies

Conference Ham, Y; Maldonado, G; Burdo, J; ...

A technical safeguards challenge has remained for decades for the IAEA to identify possible diversion of nuclear fuel pins from Light Water Reactor (LWR) spent fuel assemblies. In fact, as modern nuclear power plants are pushed to higher power levels and longer fuel cycles, fuel failures (i.e., ''leakers'') as well as the corresponding fuel assembly repairs (i.e., ''reconstitutions'') are commonplace occurrences within the industry. Fuel vendors have performed hundreds of reconstitutions in the past two decades, thus, an evolved know-how and sophisticated tools exist to disassemble irradiated fuel assemblies and replace damaged pins with dummy stainless steel or other typemore »« less

MATERIALS TESTING REACTOR-ENGINEERING TEST REACTOR TECHNICAL BRANCHES QUARTERLY REPORT, JULY 1-SEPTEMBER 30, 1962

Technical Report

9 : 5 8 < 4 9 6 6 = 9 7 8 9 5 was determined experimentally in the ETRC. This is the first phase in the development of a technique for identifying the neutron energy spectra. A method is presented for predicting the excess reactivity in the ETR as a function of power-time. A semi- empirical equation is developed which describes the time dependence of the excess reactivity in terms of certain reactivity parameters determined in the ETRC. Preliminary values were established for the infinitely dilute absorption resonance integrals of natural Hf and Rh. Measurements of the ARMFmore »« less
