Commissioner Proposes NRC Revisit Tracking of Category 3 Sources

In a memo dated July 29, 2016, NRC Commissioner Baran proposes that U.S. Nuclear Regulatory Commission (NRC) staff revisit the question of whether and how to track Category 3 sources.  In the memo, Commissioner Baran asserts that the “case for doing so is even stronger today than it was seven years ago.”

The memo concludes with the following proposed staff direction:

In light of [the Government Accountability Office’s] GAO’s findings and the years of operating experience with the [National Source Tracking System] NSTS, I propose that the NRC staff take a fresh look at the question of whether and how to track Category 3 sources. This re-evaluation can build on the efforts of the working groups established in response to the GAO investigation. I propose that, within six months of the Staff Requirements Memorandum resulting from this paper, the staff should submit a notation vote paper to the Commission that includes the following:

1)   An evaluation of the pros and cons of different methods of requiring transferors of Category 3 sources to verify the validity of a transferee’s license prior to the transfer; 

2)   An evaluation of the pros and cons of including Category 3 sources in the NSTS; and 

3)   Based on these evaluations, options for addressing the GAO recommendations.

In conducting these evaluations, the staff should assess the risks posed by the aggregation of Category 3 sources into Category 2 quantities and consider the current views of our Agreement States partners.

The memo, which has been posted to the Resources Page of the Disused Sources Working Group (DSWG) web site, is also publicly available via the “Recently Released Commission Documents for 2016” area of the NRC Web site at under Accession No. ML16197A229.
