Mr. Oliver J. Kingsley, Jr. December 8, 1988 Item 7 above requires a formal response from TVA.
We request that you provide this response within 30 days of the Appendix R audit currently scheduled for March 6, 1989.
Prior to the Appendix R audit, the staff has indicated previously that additional documentation and analyses will be required to assure BFN conformance and readiness relative to Appendix R for the plant configuration resulting from the single unit operation of Unit 2.
TVA has responded to this request by providing specific information pertaining to single-unit operation of Unit 2 by letter dated August 12, 1988.
This submittal is currently under staff review.
As previously noted, the staff intends to address the overall adequacy of fire protection in the Browns Ferry Appendix R inspection report.
If you have any questions, please contact the Browns Ferry Project Manager, Gerald E.
Gears at 301-492-0767.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than ten respondents; therefore, OMB clearance is not required.
Sincerely,
