AGREEMENT STATE REPORT INVOLVING A LEAKING SEALED SOURCE WITH CONTAMINATION
The following information was provided via fax:
"Duratek called DRH at approx. 1430 EST Jan. 17, 2008 to report a contamination event which required control of an area of their building for greater than 24 hours. While unpackaging a sealed source that was sent to them for processing for disposal, the container which the source was in was found to be contaminated. An area of about 10' by 10', covered with herculite, was contaminated and an area of 20' by 50' is being access controlled. Three personnel working at the scene were contaminated with the maximum contamination found on the personnel being 300 cpm alpha. The source was a 140 µCi U-232 solid source from the Portsmouth Facility in Ohio. The source was re-secured in containers and the contaminated area is being decontaminated. Max contamination levels on container were 400,000 dpm/100 cm2 beta/gamma and 100,000 dpm/100 cm2 alpha. The personnel were decontaminated and had lung counts. Lung counts for all were negative for elevated intake. Fecal bioassays were initiated and are ongoing.
"Media attention: None at this time.

INVALID ACTUATION OF GROUP 5 AND GROUP 10 PRIMARY CONTAINMENT VALVES DURING SURVEILLANCE TESTING
"This is not an LER. The reports being made to the NRC under 10 CFR 50.73(a)(2)(iv)(A), and the 60 day telephone notification option under 10 CFR 50.73(a)(1). The event included invalid '. . .general isolation signals affecting containment isolation valves in more than one system. . .' as discussed in 10 CFR 50.73(a)(2)(iv)(B).
"The following information is provided as requested in NUREG-1022:
"(a) The specific train(s) and systems that were actuated?
"On January 14, 2008 at 13:41 hours. Unit 2 received invalid Division 1 Primary Containment isolation signals to both Group 5 (RHR Shutdown Cooling Isolation valves) and Group 10 (Reactor Core Isolation Cooling [RCIC] system isolation valves) during Division 1 instrumentation surveillance testing. While performing testing, an incorrect lead was lifted causing this invalid actuation.
"(b) Whether each train actuation was complete or partial.
"The event resulted in closure of the RCIC steam supply header outboard containment isolation valve. The Division 1 RHR Shutdown Cooling System isolation valves were already closed at the time of the isolation signal.
"(b) Whether or not the system started and functioned as designed.
"The Primary Containment isolation instrumentation logic and associated valve closure function (for RCIC) actuated as designed."
The licensee took prompt actions to recover the RCIC and RHR systems.
The licensee notified the NRC Resident Inspector. |

EMERGENCY RESPONSE DATA SYSTEM UNAVAILABLE
"On 1/23/08 at 0010 the Unit 4 Emergency Response Data Acquisition and Display System (ERDADS) was noted to be not functioning. Reboot was attempted several times prior to achieving success. During this timeframe a loss of the ability to supply Emergency Response Data System (ERDS) data existed for greater than 30 minutes. This is also an ERDADS failure that was not corrected within 30 minutes. These fall into a 'major loss of emergency assessment capability' 10 CFR 50.72 (b) (3) (xiii). The system was restored 1/23/08 at 0045."
The licensee notified the NRC Resident Inspector. |
