SUMMARY

OF OPERATING EXPERIENCE MONTH/YEAR

- -MARCH

- - -1989---

Listed below in chronological sequence by unit is a summary of operating experiences for this month which required load reductions or resulted in significant non-load related incidents.

UNIT ONE 03/01/89 0000 This reporting period begins with the unit at CSD.

03/17 /89 2144 Loss of RHR cooling commenced due to valve mispositioning of component cooling valve by operations personnel.

03/18/89 0912 RHR cooling restored - event duration was eleven hours and twenty-eight minutes.

1302 A four hour report was made to NRC for the loss of RHR cooling.

03/31/89 1120 Notified the State Water Control Board of significant oil leak from our underground fuel oil tank.

1234 Notified the NRC of the significant oil leak from the underground fuel oil tank due to notification to the other offsite agencies.

2400 This reporting period ends with the unit at CSD.

UNIT TWO 03/01/89 0000 This reporting period begins with the unit at CSD.

03/31/89 2400 This reporting period ends with the unit at CSD.

FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR MARCH 1989 UFSAR-88-31 CHANGE NOTIFICATION 03/02/89 Page 9.4-33 of the UFSAR is incorrect and should be changed.

No unreviewed safety question is involved, administrative correction to UFSAR only.

l-TOP-2080 TEMPORARY OPERATING PROCEDURES 03/03/89 l-TOP-2081 l-TOP-2082 The spent fuel pool cleanup ion exchanger is full of spent resin and l-TOP-2083 cannot be changed out until the new spent resin transfer system is operational. The temporary modification is to allow use of temporary*

ion exchangers for spent fuel pool water cleanup.

The probability of leakage of water from the spent fuel pool is increased but the design of the system prevents lowering water level below the technical specification limit for refueling and leakage is analyzed in the UFSAR. Consequences of leakage would be loss of spent fuel

• pool cooling until water level is restored. Testing has shown several hours before loss of cooling becomes a problem and this temporary modification would not inhibit restoration of fuel pool level. Operation of the system will be in accordance with the approved procedures;

• abnormal procedures are in effect for loss of level.

2-TOP-2076 TEMPORARY OPERATING PROCEDURE DEVIATION 03/03/89 03/09/89 This deviation is to ensure availability of equipment for remotely monitoring the reactor coolant system level inventory and annunciating loss of inventory. In addition, precautions were added to help prevent PRT pressurization by not venting the unit two accumulators and requiring monitoring PR T pressure if venting the unit one accumulators.

No changes are made to the plant systems/components by this change.

The change procedurally enhances the reactor coolant system inventory control and helps to ensure shutdown cooling. No increase in accident probability, consequences or results.

TM-Sl-89-046 TEMPORARY MODIFICATION 03/06/89 Temporary modification to wire open the exhaust damper for l-VS-F-1 A.

This change does not constitute an unreviewed safety question in that the containment air recirculation system is not required to function during design basis events.

PAGE 10 e e FACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR MARCH 1989 SCAFFOLDING REQUEST 03/09/89 This request erected temporary scaffolding located in the mechanical equipment room # 3 to work insulation on west wall.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

JUSTIFICATION FOR CONTINUED OPERATION (JCO) 03/13/89 This JCO for the emergency service water system provides various restrictions and operator actions to be performed prior to completion of various modifications.

An unreviewed safety question does not exist since the JCO provides the necessary restrictions and required operator actions to assure adequate service water inventory is maintained to keep both units in the cold shutdown condition in the event of a loss of offsite power.

S2-89-20 TEMPORARY REMOVAL OF HVAC DUCT ELBOW 03/19/89 Removal of an elbow will allow increased air flow into Unit 2 relay room and will provide increased cooling.

Increased airflow will enhance the cooling in the room.

SCAFFOLDING REQUEST 03/19/89 This request erected temporary scaffolding located in the # 1 emergency diesel generator room to work '1-HS-297, HS supply to 1-HS-UH-FA.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

SCAFFOLDING REQUEST 03/19/89 This request erected temporary scaffolding located in auxiliary building 47' elevation to work 1-VS-FL-3A outlet damper, l-VS-DMP-61A.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability /function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

e PAGE 11 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR MARCH 1989 l-TOP-3007 TEMPORARY OPERATING PROCEDURE 3/25/89 Temporary procedure to open the loop bypass motor operated valves to prevent a reactor coolant system adverse condition during reduced inventory conditions pursuant to Generic Letter 88-17.

This procedure prevents a reactor coolant system adverse condition by providing a hot leg to cold leg flow path.

This procedure has no negative impacts.

'-Sl-89-62 TEMPORARY MODIFICATION .3/29/89 Temporary modification to remove auto stop signal to containment sump pumps.

No safety analyses, accident or malfunction described in UFSAR is affected.
