"On Tuesday, November 06, 2012, at 00:06 EST, during the application of a tag-out associated with feedwater level control, the 12 feedwater flow control valve (FCV-29-137) unexpectedly partially opened. As a result, reactor vessel water level rose to the high level turbine trip set point causing the main turbine to trip. The turbine trip signal then resulted in the initiation of High Pressure Coolant Injection (HPCI) channels 11 and 12 logic. No actual system component starts or actuations occurred as a result of the logic initiation and no actual HPCI injection occurred due to the system configuration, nor was injection required.
"Actions were taken to manually isolate the 12 feedwater flow control valve and reactor vessel water level was restored to normal.
"This meets NRC 8-Hour reporting criteria per 10 CFR 50.72(b)(3)(iv)(A) due to a valid actuation of the High Pressure Coolant Injection System."
The licensee has notified the NRC Resident Inspector.
* * * RETRACTION FROM JERRY HELKER TO CHARLES TEAL ON 12/17/12 AT 1543 EST * * *
"This notification is being made to retract Event Notification (EN) #48481, which reported an automatic actuation of the High Pressure Coolant Injection (HPCI) system initiation logic.
"The HPCI system is automatically initiated based on conditions representing a small break loss of coolant accident (LOCA). The initiation signals are:
- Low reactor water level - This is a direct indication of a potential loss of adequate core cooling.
- Turbine trip - During a LOCA within the drywell, high drywell pressure due to the line break will cause a reactor scram, which causes a turbine trip, which then by design initiates the HPCI system.
"The event occurred with the reactor in the cold shutdown condition, with the main turbine and main turbine shaft-driven feedwater pump (#13) out of service. In the cold shutdown condition, the probability of a LOCA is low and the HPCI system is not required by the Technical Specifications to be operable. Neither of the conditions requiring actuation of the safety function of the HPCI system (high drywell pressure or low reactor water level) was present. Although the turbine trip signal was in response to an actual sensed high reactor water level condition, high reactor water level is not a plant condition satisfying the requirement for actuation of the safety function of the HPCI system. With reactor vessel water level high, the safety function of the HPCI system (i.e. to provide adequate core cooling) was already completed. Thus, the HPCI initiation signal was invalid, and the event is not reportable under 10 CFR 50.72(b)(3)(iv)(A)."
The NRC Resident Inspector has been informed. Notified the R1DO (Hunegs). |

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text AGREEMENT STATE REPORT - STATIC ELIMINATOR MISSING
The licensee reported to the State of Iowa that they could not account for one static eliminator, NRD model P-2021, which contains a nominal 10 mCi Po-210 source. The State is investigating and will update this report when more information is obtained.
* * * UPDATE FROM RANDAL DAHLIN TO VINCE KLCO ON 12/10/12 AT 1527 EST * * *
The following information was received by facsimile:
"AGRI Industrial Plastics reported the loss of an NRD static eliminator model P-2021, serial number A2HW186 that contained a nominal activity of 0.37 GBq (10 mCi) Po-210 sealed source. The general license registrant had received seven static eliminators from NRD on October 12, 2011. The RSO for the facility discovered the device in question to be lost on December 6, 2012. The apparent cause for the lost device is human error and inattention to detail. The remaining six devices were shipped back to NRD on December 7, 2012. The corrective action for this event is that AGRI Industrial Plastics will no longer use static eliminators that contain radioactive material."
Notified the R3DO (Cameron) and the FSME Resources via email.
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.

| This material event contains a "Less than Cat 3" level of radioactive material. | Event Text TRUCK STOLEN WITH LOCKED HYDROPROBE GAUGE IN BED OF TRUCK
The following information was received via E-mail:
"The RSO for GeoLogic Associates notified the RHB [Radiologic Health Branch] that a CPN DR-503 hydroprobe #H330306914 (containing 1.85 GBq (50 mCi) of Am-241:Be) was found to be stolen on 12/7/2012. The hydroprobe's Type A transportation case was locked with two padlocks, out of sight in the rear bed of the employee's personal vehicle; a Honda Ridgeline. The vehicle was reported as stolen to the Riverside City Police Department, report #P12177015, on 12/7/2012.
"A notice for return of the stolen hydroprobe will be placed in the local newspaper if the stolen vehicle containing the hydroprobe is not recovered within 24 hours."

"This is a non-emergency notification. At 1804 PST on December 17, 2012, Diablo Canyon Unit 1 experienced a loss of plant vent continuous radiation monitors (RM) and redundant monitors 14/14R, 24/24R, 28/28R and 87. These radiation monitors are credited for Emergency Action Level (EAL) classification in the Diablo Canyon Emergency Plan. This event is reportable per 10 CFR 50.72(b)(3)(xiii) as described in NUREG-1022, Rev. 2. Compensatory measures of periodic sampling have been established in accordance with plant equipment control guidelines. Event classification can be performed by means of the sampling in accordance with plant procedures. Additionally, continuous radiation monitoring of the plant vent remains via high range radiation monitor RM-29.
"The cause of the loss of radiation monitors is not known at this time.
"This condition does not affect the health and safety of the public or the operation of the facility.
"The NRC Resident Inspector was informed." | |
