| ENS 40981 | 24 August 2004 17:30:00 | 10 CFR 50.72(b)(3)(xiii), Loss of Emergency Preparedness | North Plant Vent Radiation Monitor Skid Test Connection Valve Inadvertently Left Open. | On Tuesday 8/24/04 at 1330 hours, a test connection valve on the North Plant Vent radiation monitor skid was identified to have been inadvertently left open. This configuration issue appears to have occurred sometime on 8/19/04 following corrective maintenance on the North Plant Vent radiation monitor skid. With this valve left open, the process flow path for the skid was effectively diluted as room air was drawn into the normal process flow from the North Plant Ventilation ductwork. The physical location of the valve left open on the skid was such that the High/Low Noble Gas Range Monitors Iodine Sampler and Particulate Sampler would have been affected by this oversight. Technical Specification section 3.3.7.5 for Accident Monitoring as well as Offsite Dose Calculation Manual section 3.3.7.11 would have been applicable for the condition described. The preplanned alternate method of monitoring (sampling) the parameters was not established. This is in contrary to the requirements of Technical Specifications and the Off Site Dose manual. This condition has been corrected and the North Plant Vent radiation monitor skid is currently operable. Though alternate sampling capability was available, it was not recognized that it was required. Should an accident have occurred during the time that the valve was open emergency assessment capability would have been compromised. This report is being made under Hope Creek Event Classification Guide RAL# 11.7.1.c in accordance with 10CFR50.72(b)(3)(xiii)." Local authorities will be notified of this by the licensee. The NRC Resident Inspector will be notified of this event by the licensee. | ||
| ENS 40172 | 19 September 2003 01:11:00 | 10 CFR 50.72(b)(3)(xiii), Loss of Emergency Preparedness | Loss of Emergency Siren Capability Due to Adverse Weather Conditions | Due to the effects of severe weather related to Hurricane Isabel, local power outages have resulted in an excessive number of sirens within the Salem/Hope Creek 10-mile Emergency Protection Zone (EPZ) being unavailable. At 21:11 on September 18, 2003, 29 offsite sirens were unavailable (22 in Delaware and 7 located in New Jersey). As of 22:11, some sirens have been restored, but there are still 14 unavailable in Delaware and 7 unavailable in New Jersey. It is likely that the functionality of the EPZ sirens will continue to change due to the ongoing severe weather. Sirens will be recovered when power is restored. This notification is being for both Salem Generating Station and Hope Creek Generating Station pursuant to 10CFR50.72(b)(3)(xiii) as a major loss of emergency assessment, offsite response, or communication capability. Salem Units 1 and 2 are operating at 100% power with all safety related equipment operable. Hope Creek is operating at 94% power with all safety related equipment operable. Power is reduced due to the degraded performance of the non-safety related ventilation system that cools the Reactor Recirculation Pump Motor-Generator Sets. The licensee informed the NRC Resident Inspector.
There are currently 11 unavailable sirens within the Salem/Hope Creek 10-mile Emergency Preparedness Zone (EPZ) (6 in New Jersey and 5 in Delaware). The current availability of sirens no longer constitutes a major loss of emergency assessment capability, offsite response capability, or offsite communication capability pursuant to 10C'FR50.72(b)(3)(xiii). It is anticipated that all sirens will be rendered available as power is restored and storm recovery actions are completed. No further updates to this event report will be provided. The NRC Resident Inspector was informed. | Reactor Recirculation Pump |
