SAFETY EVALUATION This amendment request is to incorporate into the monthly operating report requirements of the Technical Specification, Section 6.9.1.6

-(Administrative Controls) to include the reporting of challenges to the Pressurizer Power Operated Valve (PORV) and the Pressurizer Code Safety Valves.(CSV).

The safety function of Technical Specifications is to provide safe operating conditions and surveillance requirements for the plant and public safety, and the safety' function of Section 6.9.1.6 is to provide.

monthly operating report of operating statistics and shutdown experience.

At present, the technical specification section 6.9.1.6 does not cover reporting of challenges to the pressurizer PORV and CSV. Also, under the revised Licensee Event Reporting System (10CFR50.73) challenges of the PORV and CSV are not reported. To comply with the NRC request dated February 8, 1984 (Log No. 1446), reportability of challenges to the pressurizer PORV and CSV will be included in the monthly operating report.

Since the safety function of the Technical Specification has not been degraded by the' proposed change, no unreviewed safety question is involved, i

v.

. . . A SIGNIFICANT HAZARD CONSIDERATION The proposed amendment request to add the requirement to report challenges to reactor coolant safety and relief valves does not represent a Significant Hazard.

Toledo' Edison was requested by a letter from the NRC dated February 8, 1984 (Log No. 1446) to submit an amendment for the reporting of challenges to reactor coolant safety and relief valves. The NRC requested this change as our present-Technical Specifications only require reporting failure of safety and relief valves. The new rule (10CFR50.73) that modifies the Licensee Event Report system does not require ceporting of challenges to safety and relief valves. By the addition to section 6.9.1.6 (monthly operating report) Toledo Edison will ensure that all challenges to the safety and relief valves will be reported.

i The Commission has provided examples of amendments which are not likely to involve a significant hazards consideration (48 FR 14870). Such as a change that constitutes an additional limitation, restriction, or control  ;

not presently included in the technical specifications: for example, a more stringent surveillance requirement. (Example 11). Toledo Edison at present does not have the proposed requirement for monthly reporting of challenges to reactor coolant safety and relief valves. The challenges will be reported in the Monthly Operating Report that is submitted to the Director, Ofilce of Management and Program Analysis and a copy to the Regional Office.

. Based on the above information, this amendment request would not (1) involve a significant increase in the probability or consequences of -

an accident previously evaluated; or (2) create the possibility of a new

.or different kind of accident from any accident previously evaluated; or (3) involve a significant reduction in a margin of safety.

Therefore, based on the above, the requested license amendment does net present a Significant Hazard.
