Dochet Ho: 50-344 Date:
1-8-79 Compiered by: G. C. Ed r Telephone:
503-556-3713 Ext. 234 Sul! MARY OF OPERATING 1:7.PERIENCE OPERATION:
The month began with the reactor in the cold shutdown condition.
The plant startup had been delayed pending license action regarding the seismic quali-fication.pf the Contro.1 Building. structure.
IIcatup began on December 25, 1978,'and the plant reached normal temperature and pressure on December 25, 1978.
The. reactor went critical at 2119 on December ~30, 1978 and zero power physics tests commenced and ' continued thtough the end of'the month.
11AJOR SAFETY-RELATED MAINTENANCE:
The spare service water pump was. reinstalled after repairs were made for the effects of part-iqulate matter.(sand) that had been ingestpd'via the suction impellers.
Modification of pipe restraints required due to the se.ismic r.eanalysis of the control building. structure gnd resultant ' change in piping restraint requirements were conclud'ed.
Saf ety injection pump B seal ' leak was ' repaired.
The contain-P ment purge inlet valve MO 10002 was repaired. '. Work continued on' assuring required clearances between turbine building and ' category 1 structures.
LICENSE:
Amendment 35, LCR-NA, LCA-NA:
Th,is -change to the license serves to waiver'.those portions of Technical Specification 5.7.1 and FSAR criter'ia that are rbt' complied with due,to-design deficiency'in the control building shear walls with regard to seisaic qualifi, cation.
ASL3 order to amend our license res,ultel in A.aea_dment 35.
Notification was received on December ^ 22, 1978 from the ASLB/NRC'to allow resumption of conditional plant operation.
A, exemption was received on December 20, 1978, addressing the 10.CFR 50.46a1 req.uirement to have a correct and approv.ed ECCS model
' error regarding zirconium-water reaction heati*ng is corrected.
This action is not related to the seismic qualification of, Trojan bu'11 dings.
The c made by,orrection will be llISCELLANEOUS:
April 1, 1979.
The Control Building seismic qualificat'idh hearings were concluded and determined that resumption of conditional power operation co61d;take pldc'e while permanent corrective actions are undertaken.
Cold weather at the end of the month resulted in several cas'es of f reezing instrument '
transmitters and process lines which required periodic attention to correct.
Installed special turbine trip sensing relay devices to provide earlier warning to BPA load dispatchers of impending generator trip to enhance grid protection.
