SUBJECT:
RESOLUTION OF SPENT FUEL STORAGE POOL SAFETY ISSUES:
ISSUANCE OF FINAL STAFF REPORT AND NOTIFICATION OF STAFF PLANS TO PERFORM PLANT-
- SPECIFIC, SAFETY ENHANCEMENT BACKFIT ANALYSES, TURKEY POINT UNITS 3 AND 4
Dear Mr. Plunkett:
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 NRC staff determined through a review of spent fuel pool design information that Turkey Point Units 3 and 4 have piping that extends to near the bottom of the spent fuel pools.
The design information indicated that this piping lacks a passive -anti-siphon device, but the piping,. is normally isolated by a locked closed valve.
Because this piping is connected to the SFP cooling and cleanup system through a normally locked closed valve and lacks passive anti-siphon protection, mispositioning of the normally locked-closed valve coincident with a pipe break or refueling water transfer operation could reduce the SFP coolant inventory by siphon flow to a level below the top of the stored fuel.
Although consistent with design standards at the time of construction, the absence of a passive anti-siphon device on piping that extends below the top of stored fuel is rare among U.S. operating reactors and contrary to current design standards for spent fuel pools.
On this basis, the staff intends to initiate activities to evaluate the potential for a safety enhancement backfit.

Mr. T.
F. Plunkett 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.
If you have any questions regarding this matter, please do not hesitate to contact me at (301) 415-1475.
