Arizona Public Service Company.
(EA 98-382)
Palo Verde Nuclear Generating Station Docket Nos. 50-528, 50-529, 50-530
~Sub'ect:
PROPOSED IMPOSITION OF CIVIL PENALTY - $55,000 This is to inform the Commission that a Notice of Violation and Proposed Imposition of Civil Penalty in the amount of $55,000 will be issued on or about December 21, 1998, to Arizona Public Service Company.
This action is based on a Severity Level III problem which involved the degraded performance capability of the HPSI system for certain accident conditions due to incorrectly assembled check valves that would have resulted in a decrease in flow to the reactor vessel significantly below the flow assumed in the safety analysis.
The ECCS flow was reduced to the extent that by"using the analysis of record, clad temperatures would have exceeded 2200' for certain accident conditions.
This condition existed for approximately 6 years in Unit 1, 5 years in Unit 2, and 1Y2 years in Unit 3. The Severity Level III problem consisted of three violations which involved: (1) failures to adhere to technical specification limiting conditions for operation when ECCS subsystems were inoperable; (2) a failure to identify and correct significant conditions adverse to quality despite numerous indicators; and (3) inadequate procedures which caused the problems and prevented timely identification of the significant conditions adverse to quality.
Because the facility has been the subject of enforcement within the last two years, the staff considered whether credit was warranted for identification and corrective action.
Credit was not warranted for identification because the problem was identified as a result of an event and the facility had numerous prior opportunities to identify it. Credit was warranted for, corrective actions because the licensee's corrective actions were considered prompt and comprehensive.
It should be noted that the licensee has not been specifically informed of the enforcement action.
The schedule of issuance and notification is:
Mailing of Notice Telephone Notification of Licensee December 21, 1998 December 21, 1998 The State of Arizona will be notified.
RI Rll Rill The licensee has thirty days from the date of the Notice in which to respond.
Following NRC evaluation of the response, the civil penalty may be remitted, mitigated, or imposed by Order.
