Source Term and Shielding Calculations to Support Decommissioning of Shippingport Reactor.

摘要

An experimental pressurized light-water reactor was operated at Shippingport, Pennsylvania from 1957 to 1982 to generate power for a public utility. The facility is being decommissioned and the reactor vessel, neutron shield tank, and radioactive internal hardware will be shipped by barge for burial on the Hanford site in Washington state. Shipping regulations require that the radioisotope inventory of the package be defined and that radiation dose rates be predicted for normal and accident conditions. Monte Carlo calculations and actual gamma-ray measurements were made to support the design of the package and preparation of paper work for the shipment. Calculational methods are described together with the results. 12 refs., 5 figs., 1 tab. (ERA citation 14:003036)
