1 NOTICE OF VIOLATION United States Enrichment Corporation Docket No. 70-7001 Paducah Geseous Diffusion Plant Certificate No. GDP-1 EA 98-556 During an NRC inspection conducted from October 15 through November 30,1998, a violation of NRC requirements was identified, in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, Rev,1, the violation is listed below:

Safety Limit 2.3.2.1 of the Technical Safety Requirements for Paducah Gaseous Diffusion Plant requires that the Normetex withdrawal pump discharge bellows pressure shall not exceed 45 psia [ pounds per square inch absolute] for all modes.

Contrary to the above, on October 17,1998, at 5:30 p.m. (Central Daylight Time), the discharge bellows pressure for the Number 1 Normetex Withdrawal Pump in Building C-315 exceeded 45 psia as the pump transitioned from Mode 2 (Withdrawal) to Mode 3 (Standby). Specifically, a pressure transient caused by the inadvertent closure of the pump discharge valve reached a maximum of approximately 50 psia.

This is a Severity Level IV violation (Supplement VI).
