k DUKE POWER COMPANY OCONEE NUCLEAR STATION Response to IE Inspection Report 50-269/80-33, -270/80-29, -287/80-26 Item A As required by Technical Specification 6.4.1.j, procedures shall be followed when performing safety-related periodic test procedures.
Contrary to the above, on October 13, 1980, periodic test procedures IP/0/A/310/12A and IP/0/A/310/13A were performed.without regard to sequence resulting in an unplanned, radioactive gaseous release of 13 curies.
This is an infraction and applies to Oconee Unit 2.
Response
This event resulted from personnel error on the part of the Nuclear Control Operator performing the tests.
He performed several steps of the two procedures simultaneously and out of sequence without approval of any member of the Station supervisory staff, and in violation of Station Directive 4.2.1, " Procedures."
For details of this incident see the letter dated November 12, 1980 from W. O.
Parker, Jr. to J. P. O'Reilly.
The NCO involved has been counseled about this incident. As additional correc-I tive action to prevent recurrence of this type incident, all licensed shif t personnel will review the incident report and Station Directive 4.2.1.
The group heads or their designees will review whether or not to limit the, number or type of procedures which can be performed simultaneously. These corrective actions will be completed by January 31, 1981.
Item B As required by Technical Specification 3.14 shock suppressorn are required l
to be operable and once an inoperable suppressor is discovered, operation may continue for a period not to exceed 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
l Contrary to the above, the oil reservoir for suppressor 3-54A-3-0-2435B-SR22 was found to be empty on August 19, 1980.
Work request 54499 was issued i
August 26, 1980 to test and repair the suppressor.
Testing was performed on September 8, 1980 and revealed the suppressor to be inoperable.
Repairs were completed on September 9, 1980 and the suppressor was restored to operable s tatus.
This is an infraction and applies to Oconee Unit 3.
Response
This item resulted from an inadequate suppressor inspection procedure which did not specify the importance of promptly reporting an empty raservoir.
The responsible engineer thus was not notified in time to have the suppressor l
restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

s o*
To prevent recurrence of this type event, all suppressor inspection procedures have been revised to require that all empty reservoirs and obvious operability problems be immediately reported to the responsible Maintenance Engineer or his designee for action. The time of inspection will be recorded on all data sheets. A Priority One work request will be issued to test and/or repair any suppressor suspected of inoperability within the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> time limit. The procedures also now require that the Shif t Supervisor be notified when a suppressor is confirmed to be inoperable so that it can be formally declared inoperable from the time of discovery.
Iteu C As required by Technical Specification 4.1, Table 4.1-2, Item 10, non-operating LPI pump casings are required to be vented prior to testing.
Contrary to the above on 10-7-80, the 3A LPI pump was started and run for PT 3/A/0230/06 LPI Performance TEST without first having been vented.
This is an infraction and applies to Oconee Unit 3.
Response
This item resulted from procedure PT/3/A/030/06 not requiring venting of the LPI pump casings prior to starting the pumps for testing. All periodic test procedures for both LPI and HPI pumps have been revised to require venting of the pump casings of non-operating pumps prior to starting for
.these tests.
