NOTES

1. Interim - Amend emergency procedure to account for valve action.

(By August 1, 1930)

Long term - Conduct engineering study to identify need for ad-ditional corrective action. (By October 1, 1980)

2. Administrative controls have already been implemented on the device. Tnis valve / equipment has been identified in Emergency Procedure 35 as a device that changes state upon reset. Engi-neering review to be conducted to determine if circuit modification is required. (By October 1, 1980)

3. Amend Emergency Procedure 35 to ' entify that this device can conceivably change state. (By ,ust 1, 1980)

4. Procedures will be changed to eliminate the possibility of tripping the 4160V ESF pump breakers. (By August 1, 1980)

Modifications to eliminate the potential tripping of the 4160V breakers will be made. (During 1981 refueling outage)

5. Actuated by Recirculation Actuation Signal, changes position upon reset.

6. Actuated by Safety Injection Actuation Signal, changes position upon reset.

7. Load Shed actuated, changes upon reset.  ;

8. Actuated by Containment Spray Actuation Signal, changes upon reset.

9. Load Shed actuated, pump starts on combination of reset and high level .

l

10. As installed, the circuitry is such that if both 86A/0PLS and i 86B/MS are tripped, the resetting of one of the lockouts will 1 trip the 4160V ESF pump breakers associated with the train on which l lockout relay is being reset. No breaker trips will occur as a result of the resetting of the second OPLS lockout.

11. Actuated by Ventilation Isolation Actuation Signal, changes posi-tion upon' reset.

12. Actuated by Containment Isolation Actuation Signal, closes with loss of pressure.

13. Actuated by Containment Isolation Actuation Signal, changes upon reset.
