Event Notification Report for April 06, 2010

STORM DRAIN SYSTEM TESTED POSITIVE FOR TRITIUM

"On 4/06/10, Salem management was notified that samples taken from the Salem Unit 2 north storm drain system were positive for tritium. Two storm drain catch basin sample results were confirmed above 1 million pico Curies per liter. The affected area of the north storm drain system has been isolated. Samples upstream of the river outfall were less than the minimum detectable level for tritium.

"NRC reporting criteria were reviewed and, although no direct reportable criteria were met, based on the public sensitivity to tritium issues, it was determined that a voluntary notification to the NRC was prudent.

"Salem is taking action to mitigate, locate, and remediate the source of the tritium. In addition to isolating the affected portion of the system, the station has increased the sample frequency for the storm drain system and ground water wells in the affected area.

"A voluntary notification has been made to the appropriate State agency and the NRC Resident Inspector."

"Based on further evaluation, Salem officially notified the New Jersey Department of Environmental Protection of the above tritium spill on 4/8/10 at 2003. This notification to New Jersey is reportable in accordance with 10 CFR 50.72(b)(2)(xi)."

INITIATION OF TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO CONTROL ROOM EMERGENCY FILTRATION SYSTEM BEING DECLARED INOPERABLE

"At 1650 PDT Columbia Generating Station entered LCO 3.0.3 as required by LCO 3.7.3 for both divisions of Control Room Emergency Filtration (CREF) [being] inoperable. Entry into LCO 3.0.3 was required by Condition E of LCO 3.7.3, 'Two CREF subsystems inoperable in MODE 1, 2, or 3 for reasons other than Condition B' and has a Required Action to enter LCO 3.0.3 with an immediate Completion Time. Columbia commenced a plant shutdown at 1747 as required by LCO 3.0.3.

"[Columbia Generating Station] entered into Condition E of LCO 3.7.3 when it was determined that Radwaste Building Outside Air Smoke Detectors WOA-SMD-1A and WOA-SMD-1B did not meet seismic qualifications. Actuation of these smoke detectors would cause Radwaste Building Mixed Air Fire Dampers WMA-FD-1 and WMA-FD-2 to close. These fire dampers shutting would cause all CREF airflow to cease, preventing the control room from achieving a positive pressure. Both divisions of CREF [being] inoperable is an unanalyzed condition requiring immediate entry into LCO 3.0.3.

"This event is reportable under 50.72(b)(2)(i) due to the initiation of a plant shutdown as required by Columbia's Technical Specifications. This event is also reportable under 50.72(b)(3)(v)(D) as an event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to mitigate the consequences of an accident.

"WMA-FD-1 and WMA-FD-2 have been deactivated in the open position for the smoke actuation function. [Columbia Generating Station] entered RFOLCS (Requirements for Operability of Licensee Controlled Specifications) 1.10.6 for these fire dampers [being] nonfunctional. [Columbia Generating Station] completed the required actions of LCS 1.10.6.

"The CREF system remains inoperable pending completion of a TMR (Temporary Modification Request)."

The licensee notified the NRC Resident Inspector.

* * * UPDATE FROM QUOC VO TO CHARLES TEAL ON 4/7/10 AT 1957 * * *

"Question posed by NRC at time of initial report: Have these smoke detectors been installed since startup?

"Response: These smoke detectors have been installed since initial plant startup.

"A temporary modification request was installed to de-energize the non-seismic detector logic that causes automatic fire damper actuation for the two dampers identified above. The alarm function of the smoke detectors remains active with this temporary modification.

"Entry into this condition was made when it was determined that the smoke detectors were not seismically qualified and there is a possible failure mode that during an earthquake the detectors would actuate the electro-thermal link and cause the associated fire damper (WOA-FD-1 or WOA-FD-2) to close, hence impacting control room emergency filtration function.

"With implementation of the temporary modification at 2218 PDT on 4/6/10, the CREF system is now considered to be in an 'operable but non-conforming' status. As such, LCOs 3.7.3 and 3.0.3 were exited at 2218 PDT on 4/6/10.

"This event was initially reported pursuant to paragraph 50.72(b)(2)(i) as an initiation of a plant shutdown required by Columbia's Technical Specifications. Reporting pursuant to paragraph 50.72(b)(2)(i) is being retracted because negative reactivity was not inserted into the reactor prior to exiting the LCOs described above. Reporting pursuant to paragraph 50.72(b)(2)(i) would not be consistent with the guidance provided in NUREG-1022 in that no negative reactivity was inserted and the condition was corrected before exceeding the required action times."

The licensee notified the NRC Resident Inspector.

* * * RETRACTION FROM KYLE CHRISTIANSON TO PETE SNYDER AT 1550 EDT ON 4/29/2010 * * *

"Subsequent to the April 7, 2010, event report (EN #45816), an Energy Northwest engineering evaluation concluded that the identified smoke detectors would not inadvertently actuate during a design basis safe shutdown earthquake (SSE). This conclusion is based on a seismic response spectrum test report for the smoke detectors. Therefore, since the safety function of the CREF system needed to mitigate the consequences of an accident would not be affected by an SSE, the event notification made pursuant to 10 CFR 50.72 (b)(3)(iv)(D) is hereby retracted."

"The NRC Senior Resident Inspector (Cohen) has been notified."

Notified R4DO (Clark).

AGREEMENT STATE REPORT - LOSS OF TRAINING BUTTON SOURCE

The following information was received via fax:

"A Training button source was lost on 3/6/2010 during training in Alachua county. The training facility was searched and the source was not found. Corrective actions include additional source handling procedures, daily checklists for use of sources, and training on proper notification to RSO of all events regarding use of RAM. No further action will be taken on this incident."

Florida Incident Number: FL10-049

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source

OHIO AGREEMENT STATE REPORT - D90 DOSE LESS THAN PRESCRIBED DOSE

The following information was obtained from the State of Ohio via email:

"Note: This information is reported as a result of a special inspection performed [by the State of Ohio] on July 28 and 29, 2010, limited to the licensee's prostate implant program.

"The licensee performed a prostate seed implant on April 6, 2010. The patient was prescribed a dose of 100 Gy using Iodine-125 seeds. The D90 post implant dosimetry performed on May 12, 2010, indicated a D90 of 62.5 Gy was given. This is a difference of 37.5% from the prescribed dose. The post plan dosimetry was performed by a radiation therapist on May 12, 2010, and the results were reviewed by a medical physicist on May 18, 2010. This qualifies as a Medical Event per rule 3701:1-58-101(A)(1)(a) of the Ohio Administrative Code (OAC).

"The licensee failed to notify by telephone the Ohio Department of Health no later than the next calendar day after the discovery of the medical event, and submit a written report within fifteen days after discovery of the medical [event]. This is a violation of ODH requirements as referenced in rule 3701:1-58-101 (c) and (D)."
