SUBJECT:

RESOLUTION OF SPENT FUEL STORAGE POOL SAFETY ISSUES:

ISSUANCE OF FINAL STAFF REPORT AND NOTIFICATION OF STAFF PLANS TO PERFORH PLANT-

SPECIFIC, SAFETY ENHANCEMENT BACKFIT ANALYSES, WASHINGTON NUCLEAR PROJECT NO.

2 (WNP-2)

(TAC NO. M88094)

Dear Mr. Parrish:

The Nuclear Regulatory Commission staff recently completed a detailed review of spent fuel storage pool safety issues.

The results of the staff's review are documented in a report to the Commission which is enclosed for your information.

In the report, the staff concludes that existing structures,

systems, and components related to the storage of irradiated fuel provide adequate protection of public health and safety.

Notwithstanding this finding, the staff has also identified certain design features that reduce the reliability of spent fuel pool decay heat removal, increase the potential for loss of spent fuel coolant inventory, or increase the potential for consequential loss of essential safety functions at an operating reactor.

The staff intends to conduct plant-specific regulatory analyses to evaluate potential safety enhancement backfits pursuant to 10 CFR

50. 109(a)(3) at a number of operating plants that possess one'or more of these design features.

The staff noted that WNP-2 appears to be reliant on infrequently operated backup SFP cooling systems to address long-term LOOP events and mechanical failures.

The staff will examine administrative controls on the availability of the backup cooling systems during refueling and technical analyses demonstrating the capability of these backup systems to cool the SFP at WNP-2 to determine the need for further regulatory analyses.

If you wish to comment on the accuracy of the staff's understanding of the plant design, the safety significance of the above design features, the cost of potential modifications to address the above design features, or the existing protection from the above design concerns which may be provided by administrative controls or other means, comments received before November 15, 1996, will be considered in developing plans for inspections and other activities associated with the planned regulatory analysis.
