PY-CEI/NRR-1961L i Attachment 3 l Page 1 l SIGNIFICANT HAZARDS CONSIDERATION The standards used to arrive at a determination that a request for amendment involves no significant hazards considerations are included in the Commission's Regulations, 10 CFR 50.92, which state that the operation of the facility in accordance with the proposed amendment would not (1) involve a significant increase in the probability or consequences of an 4

accident previously evaluated, (2) create the possibility of a new or different kind of accident from any previously evaluated, or (3) involve a

, significant reduction in a margin of safety.

$ The proposed amendment has been reviewed with respect to these three factors and it has been determined that the proposed change does not involve a significant hazard because:

1. The proposed change does not involve a significant increase in the i probability or consequences of an accident previously evaluated.

The proposed TS change requests one-time only extensions of the surveillance intervals related to TS SR 4.3.3.1, Table 4.3.3.1-1, Items D.1 and D.2, Division 1, 2, and 3 Degraded Voltage and Undervoltage l instrumentation calibration. As discussed in Attachment 1, extension of the interval for this instrumentation is acceptable based on the testing  !

results from the past two refueling outages. No failures have occurred  !

which would negate the assurance that the instrumentation vould function  ;

as required for the requested extended period. Accordingly, the  !

proposed change vill not significantly increase the probability or l' consequences of an accident previously evaluated.

2. The proposed change vould not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed TS change requests one-time extensions of the surveillance intervals for the Division 1, 2, and 3 Undervoltage and Degraded Voltage instrumentation calibration. The proposed changes do not i necessitate a physical alteration to the plant (no new or different type of equipment vill be installed). In that the requested extension durations are small as compared to the overall interval allowed by TS and past testing results provide confidence of no effect on equipment availability by extending the surveillance interval, the change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

'3.- The proposed change vill not involve a significant reduction in the margin of safety.

The proposed TS change requests a one-time e; *ension of the surveillance intervals for the Division 1, 2, and 3 Under' ltage and Degraded Voltage instrumentation calibration. The proposed enanges do not necessitate a physical alteration to the plant (no new or different type of equipment t

vill be installed). In that the requested extension durations are small '

as compared to the overall interval allowed by TS and past testing results provide confidence of no effect on equipment availability by extending the surveillance interval, the change does not involve a significant reduction in the margin of safety.
