This voluntary notification is being made to inform the NRC of a condition that may be of interest to the public.
Upon arrival at the Barnwell South Carolina waste disposal facility, a shipping cask containing irradiated hardware that was shipped from Nine Mile Point Nuclear Station (NMPNS) [Unit 2] was observed to have a number of bolts that were not fully torqued [Six of 12 bolts were not fully torqued]. The subject bolts secure the cask base plate to the cask body. There was no radiological safety concern associated with the bolting condition as survey results confirmed that no radioactivity leaked from the cask. This issue has been entered into the NMPNS corrective action program and an investigation is underway to determine the cause of the as-received bolting condition.
The licenses notified the NRC Resident Inspector and
New York Public Service Commission.
