- v RESPONSE TO NOTICE OF VIOLATION VIOLATION NUMBER 50-395/89-13-01 I.
ADMISSION OR DENIAL'0F THE VIOLATION South Carolina Electric & Gas Company (SCE&G) is in agreement with the alleged violation.
II.
REASON FOR'THE VIOLATION Procedures were inadequate in that an evaluation was not performed' prior to installing two temporary demineralizers_to permit draining of the' steam generators.
In addition, a work document was not initiated.
which would have required an' evaluation, allowed tracking the installation, and insured removal prior to mode escalation.
III.-
CORRECTIVE STEPS TAKEN AND RESULTS ACHIEVED Demineralized units were removed on July 6, 1989. An Engineering evaluation was conducted to determine if the temporary demineralizers could have prevented the Service Water or Component Cooling Water Systems from performing their design basis function during a seismic event.
It was determined that the condition did not place the plant outside the design basis or reduce the margin of safety.
IV.
CORRECTIVE ACTIONS TAKEN TO AVOID FURTHER VIOLATIONS A Health Physics procedure is in development which'will delineate the necessary requirements'for installation / removal of portable or temporary demineralizers.
In the interim, the established Removal and Restoration Program will be used to establish data and mode restraints to ensure that this equipment is removed, when required, prior to unit startup.
In addition, plant procedures will be revised to ensure temporary equipment / scaffolding is removed, when required, prior to Mode 4.
V.
DATE OF FULL COMPLIANCE Procedure will be reviewed / approved by December 31, 1989.
