SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 160 TO FACILITY OPERATING LICENSE NO. DPR-32 AND AMENDMENT NO.159 TO FACILITY OPERATING LICENSE NO. DPR-37 VIRGINIA ELECTRIC AND POWER COMPANY SURRY POWER STATION, UNIT NOS. 1 AND 2 DOCKET N05. 50-280 AND 50-281
1.0 INTRODUCTION
The licensee, Virginia Electric and Power Company, in its submittal dated July 1, 1988, as modified October 20, 1989, proposed to amend the Technical Specifications (TS) to facility Operating License Nos. DPR-32 and DPR-37 The proposed amendments would revise TS Sections 3.1.D.3, 3.1.D.4 and 6.6.A.2.
Technical Specification 3.1.D.3 currently requires that a Special Report be submitted if the reactor coolant iodine activity limits are exceeded for 300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br /> in a 6-month period. This specification (3.1.D.3) would be eliminated with the appropriate reporting requirement being fulfilled under TS Section 6.6.A.2.
Technical Specification Section 6.6.A.2 would be revised to include iodine spiking information in an annual report.
Technical Specification Section 3.1.D.4 would also be revised to delete information regarding fuel
-burnup by core region.
2.0 EVALUATION Generic Letter 85-19, " Reporting Requirements on Primary Coolant ;odine Spikes,"
states that licensees may eliminate the requirement in the TS to shut down a plant if the reactor coolant activity limits are exceeded for 800 hours0.00926 days <br />0.222 hours <br />0.00132 weeks <br />3.044e-4 months <br /> in a 12-month period. This is due to the fact that the quality of nuclear fuel has been greatly improved over the past decade with the result that normal coolant iodine activity (i.e., in the absence of iodine spiking) is well below the limit.
No corresponding shutdown requirement exists in the current Surry, Units 1 and 2 TS.
However, Surry TS Section 3.1.D.3, which the licensee has proposed to delete, specifies that a Special Report be submitted if the reactor coolant iodine activity limits are exceeded for 300 hours0.00347 days <br />0.0833 hours <br />4.960317e-4 weeks <br />1.1415e-4 months <br /> in a 6-month period. Generic Letter 85-19 also states that the reporting requirements for iodine spiking can be reduced from a short-term report, such as a Licensee Event Report or a Special Report, to an item which is included in an annual report.
The licensee initially proposed to revise TS Section 6.6.A.3 to include this information in the.
Monthly Operating Report; however, based on discussions with the staff, the licensee amended its initial application to require such reports on an annual basis. This is in accordance with the staff guidance set forth in Generic Letter 85-19, and is therefore acceptable.

l Moreover, the licensee, in accordance with Generic Letter 85-19, proposed to delete information regarding fuel burnup by core region from TS Section 3.1.D.4 As stated in Generic Letter 85-19, 10 CFR 50.72(b)(1)(ii) requires the NRC to be immediately notified of fuel cladding failures that exceed expected values or that are caused by unexpected factors. This TS limit is no longer considered necessary on the basis that proper fuel management by licensees and existing reporting requirements should preclude ever approaching the lin.it.
Based on our review of the licensee's submittal, we conclude that the proposed amendments conform with the guidelines presented in Generic letter 85-19 and are acceptable.
3.0 STATE CONSULTATION
In accordance with the Commission's regulations, the Virginia State official was notified of the proposed issuance of the amendments. The State official had no comment.
4.0 ENVIRONMENTAL CONSIDERATION
These amendments relate to changes in reporting requirements. Accordingly, these amendments meet the eligibility criteria for categorical exclusion set forth in 10CFR51.22(c)(10).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of these amendments.
5.0 CONCLUSION
The Commission has concluded, based on the considerations discussed above, that:
(1) 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 these amendments will not be inimical to the common defense and security or to the health and safety of the public.
