0m, T M OCT ?5 2006 U. S. Nuclear Regulatory Commission Attn: Document Control Desk Mail Stop OP1-17 Washington, DC 20555 SUSQUEHANNA STEAM ELECTRIC STATION LICENSEE EVENT REPORT 50-387/2006-005-00 PLA-6122 Docket 50-387 Attached is Licensee Event Report 50-387/2006-005-00. This event was determined to be reportable per 10 CFR 50.73(a)(2)(v)(D) when surveillance testing revealed a condition that could have compromised the Unit 1 High Pressure Coolant Injection System's ability to respond within Technical Specification time limitations.
There were no actual consequences to the health and safety of the public as a result of this event.
No new regulatory commitments have been created through issuance of this report.
