FROM:
Wmiam D. Travers Executive Director for Operations L
SUBJECT:
DIFFERING PROFESSIONAL OPINION CONCERNING VOLUMETRIC INSPECTION OF WELDS IN SPENT FUEL STORAGE CANISTERS
)
Attached is a copy of the report, dated April 15,1999, that was issued by the panel I chartered 1
to review a Differing Professional Opinion concerning the non-destructive examination of welds l
In austenitic stainless steel dry storage casks.
The panel made three recommendations: (1) the staff should continue to work closely with the American Society of Mechanical Engineers (ASME) to speed the development of a consensus standard specifically applicable to these casks and should take timely action to endorse the standard, with limitations, if necessary; (2) the staff should not provide full inspection oversight of the welding and inspection process; and (3) the staff should consider a risk analysis on austenitic stainless steel casks as a followup to the integrated safety analysis work on the Ventilated Storage Cask Model No. 24. I concur with these recommendations. I request that you continue to work with ASME on a consensus standard and that you perform such a risk assessment, on a schedule that considers other actions in the Office.
