Letter V. Stello to C. C. Andognini dated July 8,1980
Dear Sir:
This letter is in response to the Notice of Violatica dated July 8, 1980 which states that I was not in full corpliance with my Senior Operator License (No. SOP-1585-4) in that I icitiated refueling activities without verifying secon?ary containment and without verifying conformance with the requirements of PNPS Procedure 4.3.
As the Sentor Licensed Operator I was directing the activities of licensed operators on the refueling floor on March 8, 1980.
I would like to provide you with some insight as, to the circumstances which I believe caused this item of noncompliance and to inform you of the actions-I have take~n to prevent re-currence of a similar noncompliance.
During the evening of March 7, 1980 (1600 to 2400 hrs) as Refueling Floor Supervisor, I had supervised the unlatching of the last control rod to be re-moved from the reactor vessel during the outaga. As this control rod un-latching ccmpleted all of the scheduled in-vessel work, I returned to the main control room to plan ny work for the next shif t (0000 to 0800 hrs).
While in the control room I performed a routine evaluation of the availability of the systems required for fuel handling.
I neted that both trains of the Standby Gas Treatment System were operable. I also was aware that the auto close feature of the emergency diesel generator had been temporarily modified to pre-clude a possiblity of their closing on the bus out of phase with the 23 kv lines and that the control room personnel were cognizant of this condition and had been instructed of all actions requtred by them, if an auto start of the diesel generators occurred.
Nothing I learned during either my visual inspection or my discussions with the control room personnel gave me reason to suspect that secondary containment integrity was other than intact as previously demonstrated during the successful performance of the leak rate test in January 1980.

.The Chief Operating Engineer's instruction log specified that two fuel elements were to be reoriented in the spent fuel pool when the work schedule would perndt it As I had completed all other scheduled refuel floor activities, I returned to the refuel floor and supervised the reorientation of the two fuel bundles withira the spent fuel pool as specified on FBA Transfer Form #828. Procedure 4.3 " Fuel Handling" was not utilized during this maneuver as it did not include a checklist applicable solely to fuel movenent ultl.in the spent fuel pool.
Upon completion of the fuel movement I notified the control room to enabic them I
to update the status of the fuel tag boards maintained in the control room.
Iogged the fuel movement in the Refueling Floor Supervisor's Log when I returned to the control room, prior to completica of my shift.
The ORC's met during the af ternoon on March 8,1980 and determinc.1 that the fuel movement which had been made under my supervision had in fact been made without secondary containuent integrity intact and I was subsequently made aware of their determination.
During the dayn following the incidrat, I participated in meetings with members 4
l-of station management to determine the events which led to the occurrence of the incident.
I provided direct input into the development of corrective actions, both immediate and long term to preclude a recurrence of the event.
I made suggestions to station management concerning ways to revise station procedures and checklists utilized during fuel handling.
I was instrumental in developing the training meetings given to all licensed operators prior to the recommence-ment of fuel handling to assure that myself and the other licensed personnel were aware of the situations and the corrective actions taken in response.
I have assisted in developing training sessions to be implemented during the next
~
scheduled training program in the fall and immediately prior to the next refueling outage.
Please note that Revision 16 to Procedure 4.3 " Fuel Handling" was in effect on March 8, 1980 and that this revision did not require convening ORC for their review of plant conditions and for their approval to begin f uel movement.
This requirement was added to Procedure 4.3, Revision 17, on, March 20, 1980 as im-mediate corrective action in response to the subject event.
Therefore I at no time violated the requirements of Procedure 4.3 I wish to emphasize that, at no time, did I willfully disregard the commissions regulations or deliberately violate any applicable requirements or procedures.
Ver v truly yours, John Alukonis cc:
