The Transportation, Aging and Disposal (TAD) canister-based system is being
proposed to transport and store spent nuclear fuel at the Monitored Geologic Repository
(MGR) located at Yucca Mountain, Nevada. The preliminary design of this system
identifies borated stainless steel as the neutron absorber material that will be used to
fabricate fuel basket inserts for nuclear criticality control. This paper discusses corrosion
test results for verifying the performance of this material manufactured to the
requirements of ASTM A887, Grade A, under the expected repository conditions.
