SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 62 TO FACILITY OPERATING LICENSE NO. NPF-58 THE CLEVELAND FIECTRIC ILLUMINATING COMPANY. ET AL.
PERRY NUCLEAR POWER PLANT. UNIT NO. 1 DOCKET NO. 50-440
1.0 INTRODUCTION
By letter dated February 28, 1992, the Cleveland Electric illuminating Company, et al. (licensees), proposed changes to the Technical Specifications (TSs) for the Perry Nuclear Power Plant, Unit No.1.
The change requested deletion of the area criticality monitors for the fuel preparation and storage pool, spent fuel storage pool and the upper containment pools from TS Table 3.3.7.1-1, " Radiation Monitoring Instrumentation" and Table 4.3.7.1-1,
" Radiation Monitoring Instrumentation Surveillance Requirements."
2.0 EVALUATION The NRC staff has reviewed the proposed changes to the TS regarding removal of the area criticality monitors for the fuel preparation pool, spent fuel pool, and upper containment pools.
The proposed changes do not affect the methods that prevent criticality, specifically the design of the pools, spacing requirements maintained in the pools, requirements for specific levels or quantities of neutron absorbers, and maintaining cooling and shielding by requiring specific pool water levels.
Criticality evaluations are provided for the fuel preparation pool, spent fuel pool, and upper containment pools in Updated Safety Analysis Report (USAR)
Section 9.1.2.
No credit is taken in these analyses for the area criticality monitors.
The area criticality monitors provide only an alarm function when radiation levels increase above their setpoint (equal to or greater than 5 mR/hr and less than or equal to 20 mR/hr), and, by themselves, initiate no action to prevent or mitigate an event.
Since the licensee will continue to utilize the existing monitors as area radiation monitors as discussed in USAR Section 12.3.4.1.2, the monitors will alert personnel if radiation levels exceed the monitors' setpoint.
9407060044 940628 PDR ADOCK 05000440 p
As specified in 10 CFR 70.24, criticality monitoring requirements are not intended to require underwater monitoring when special nuclear material is handled or stored beneath water shielding.
This same change is included in the licensee's submittal (PY-CEI/NRR-1732 L) to improve and reformat the PNPP TS, based on NUREG-1434, " Improved BWR-6 Technical Specifications,"
Revision 0, September 1992.
Based on the above, the NRC staff finds the proposed changes to be acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Ohio State official was notified of the proposed issuance of the amendment.
The State official had no comments.
4.0 ENVIRONMENTAL CONSIDERATION
Pursuant to 10 CFR 51.21, 51.32, and 51.35, an environmental assessment and finding of no significant impact has been prepared and published in the Federal Register on June 17, 1994 (59 FR 31272).
Accordingly, based upon the environmental assessment, the Commission has determined that the issuance of this amendment will not have' a'significant effect on the quality of human environment.
5.0 CONCLUSION
The staff has concluded, based on the considerations discussed above, that:
(lJ there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
