摘要

RA-6 reactor is located in Bariloche Atomic Centre (CAB), in the city of San Carlos de Bariloche, inthe south of Argentina. In 2005, CNEA and DOE signed a contract for the conversion of the RA-6 reactor to LEUand for shipping back in a single shipment the HEU spent fuel inventory that consisted of 42 MTR - type fuelassemblies. The shipment activity was performed in the frame of the DOE′s Spent Fuel Acceptance Program. Theshipment campaign took place in the last quarter of 2007 and the receiving facility for the RA-6 fuel wasSavannah River Site. One unit of a NAC – LWT shipping cask was used to ship the fuel. In order to place inside itall the fuel assemblies, cropping of their non active parts (structural parts) was required. In order to provideadequate shielding to the operators, fuel cropping was performed under water. Transfer of baskets loaded withconditioned fuel to the transport cask was made by shielded intermediate transfer systems. Especially designedshielded drums were manufactured for the storage of the cropped parts that remained in the reactor site asmedium-level radioactive waste. After testing of the loaded LWT (radionuclide sampling test, helium test), thepackage check out was completed by measuring the superficial contamination ( and β/γ emitters) and the doserate in contact and at 1 m. An additional requirement was to verify that the package was “self-protected”. The ISOcontainers with the package and with the auxiliary equipment were also subjected to an equivalent radiologicalcontrol. The typical daily staff that participated in the loading campaign was about twelve people. The collectivedose was 0.72 mSv.man.
