| Title | 4-Hour Report Due to Notification of Ohio Epa Because of Boiler Opacity Limit Being Exceeded |
| Event Description | At 2130 hours0.0247 days <br />0.592 hours <br />0.00352 weeks <br />8.10465e-4 months <br />, 07/06/09, the PORTS Plant Shift Superintendent's (PSS) Office was notified of an operational upset at the X-600 Steam Plant Facility due to a loss of power on the #3 (operating) Boiler. The operational upset resulted in three separate six minute periods, where the permissible opacity limit was exceeded, while power was being restored to the boiler. The PORTS PSS Office notified the Ohio Environmental Protection Agency (OEPA) of this incident, at 0054 hours6.25e-4 days <br />0.015 hours <br />8.928571e-5 weeks <br />2.0547e-5 months <br />, 07/07/09. This notification to another government agency is reportable to the NRC as a 4-hour Event, per the United States Enrichment Corporation (USEC) Nuclear Regulatory Event Reporting Procedure UE2-RA-RE1030, Appendix D, Section P (Miscellaneous) which states: 'USEC shall notify NRC of any event or situation, related to the health and safety of the public or on-site personnel, or protection of the environment, for which a news release is planned or notification to other government agencies has been or will be made. Such an event may include an on-site fatality or inadvertent release of radioactively contaminated materials'.
The licensee notified the Paducah NRC Resident Inspector.
PORTS [Nuclear Regulatory Affairs] NRA has reviewed the basis for the above NRC event notification and recommends that event notification #45188 be retracted. The following provides the basis for this recommendation. NUREG-1022, Event Reporting Guidelines 10 CFR 50.72 and 50.73 was reviewed. In essence, the following sentence from the NUREG provides sufficient clarification of the reporting criteria to assess the applicability of the steam plant opacity exceedances: 'The purpose of this criterion is to ensure the NRC is made aware of issues that will cause heightened public or government concern related to the radiological health and safety of the public or on-site personnel or protection of the environment.' The significance of opacity exceedances as they might impact the public or on-site workers was discussed with environmental compliance personnel. It was concluded that beyond any regulatory issues, opacity exceedances of limited duration pose no significant health or environmental concerns. Based on the specifics of this event and the additional guidance provided by the NRC, more specifically that NRC is most concerned about events or situations that would cause heightened public or government concern, the opacity exceedances reported to the OEPA should not trigger a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> NRC report. The licensee notified the NRC Resident Inspector. Notified R2DO(Nease) and NMSS EO(Tschiltz) |
