SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION REQUEST FOR EXEMPTION j
FROM OFFSITE EMERGENCY PLANNING REQUIREMENTS (TAC NO. M99689)
Dear Mr. Powers:
We are continuing our reviesy of your proposed changes to'your requested exemptions from emergency planning requirements, as detailed in your. letter to us dated September 19, 3
1997. However, in order for us to independently evaluate your conclusion that the spent i
fuel stored at BRP would ot be susceptible to a zircalloy fuel clad fire and would not result l
in offsite radiological dose consequences in excess of Environmental Protection Agency Protective Action Guides, should the spent fuel pool be drained of all water, we require j
site-specific dimensions and construction information pertaining to the BRP wet spent fuel i
l storage system. The roquested information was discussed with members of your staff on I
l February 12,1998, and we acknow! edged that additional discussions may be necessary to l
assure that the correct dimensions are obtained. This request affects nine or fewer respondents and therefor 6, is not subject to Office of Management and budget review under P.L. 96 511. In accordance with 10 CFR 50.30(b), your response must be executed in a signed original under oath or affirmation.
If you have any questions regarding this request, please contact me at (301) 415-1169.
