Matropolitan Edison Company Opprating License No. DPR-50 Docket No. 50-289 Inspection Report No. 78-19 RESPONSE TO VIOLATION General Restense:
To. ensure that all of the Operating Procedures have received sufficient f
review, the Operations Engineer has been tasked to audit the Control i
Room file of Operating Procedures and identify and correct any additional discrepancies of this nature.
This audit is expected to be complete by March 1979 Specific Restonse:
Infraction (1):
- Changes were made to Operating Procedure (0P) 1103-2, " Filling and Venting Reactor Coolan: (RC) System," completed April 18, April 26, and April 28, 1978.
The changes, which did not alter the intent of the original procedure, were not approved, documented or reviewed.
Response
i Procedure Change Request (PCR) #78-909, to CP 1103-2 was submitted on 11/9/78.
PCR #78-909 vill ensure that these minor changes become a permanent change to the procedure.
PCR #78-909 vill become effective by January 15, 1979 Infraction (ii):
?
OP 110h-2, " Makeup and Purification System," which provided requirenents for l
each system startup and shutdown, had been used for multiple system startup and shutdown evolutions performed on April 25, April 28, June 22, and June 27, 1978.
In addition, verification of individual step (by operator initialing) and system startup satisfactory completion (by licensed operator signature),
as required by 0P 110h-2, was not ecmpleted for the system startup on June 27, 1978.
4
Response
Review of OP 110h-2 vith respect to these discrepancies, identified a procedural inad.equacy, in that the startup and shutdown sequence of evolutions could be confused to require a shutdown before a startup was complete.
Procedure i
Change Request #78-933 to OP 110h-2 was submitted on 12/8/78 to clarify this i
' sequence of operation.
PCR #78-933 vill help to ensure that this discrepancy does not occur.1:1 the future.
FCR #78-933 vill become effective by January 15, 1979 Infraction (iii):
[~
OP 1104 h, "DecayfHeat Removal System," completed April 28, and June 22, 1978, did not indicate completion of steps in Enclosure (1), Startup Valve i'
Checklist. In addition, the procedures required completion of an Enclosure (2), which did not exist.
i
.~
\\
Rdsponse:
A review of Il0h h, indicated an oversight in the Procedure revision process which did not renove the references to Enclosure (2).
Procedure Change Request #78-9h9 tc CP 110h h, submitted on 12/8/78, vill correct this oversight.
POR #78-9h9 vill becc=e effective by January 15, 1979 Infraction (iv):
Satisfactory completion of the post-refueling approach to criticality on April 28, 1978, could not be demonstrated by a cenpleted OP 1103-8,
" Approach to Criticality."
Besponse:
Further review of this discrepancy reveals that initial cycle criticality is achieved in accordance with Physics Test Precedure 1550-02.
All of the required critical data for the April 28, 1978 approach to criticality after refueling is doc"~aa*ad in PTP 1550-02. OP 1103-8 is used for a return to criticality other than after a refueling.
Therefore, no corrective action is deemed necessary.
Infraction (v):
Surveillance Procedure 1301-9. 5,'Teactivity Anocaly," completed and reviewed October 31, 1978, was not properly inplemented in that a data sheet contained an incorrect value for the power correction to reactivity.
Another unlisted, but correct, value was used in the cenputation of reactivity anomaly.
The erroneous data was not identified during subsequent procedure check and approval required by SP 1301-9.5
Response
Following the identification of this discrepancy concerning the incorrect value for the power correction to reactivity, a corrected data sheet was placed in the October 31, 1978, SP 1301-9.5 i
