"On July 17, 2012, at 1120 hours the Control Room Emergency Ventilation Air Conditioning (CREV AC) system was declared inoperable due to a cooling water leak from the condenser on the Refrigeration Compressor Unit (RCU). The leakage originates from an apparent gasket leak at a bolted connection on the condenser. As a result, Technical Specification 3.7.5, Condition A, was entered. A repair plan and schedule is being developed.
"The CREV AC system maintains a habitable control room environment and ensures the operability of components in the control room emergency zone during accident conditions.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(v)(D) because the CREV system is a single train system, and loss of the CREV AC could impact the plant's ability to mitigate the consequences of an accident."
The licensee has notified the NRC Resident Inspector.
* * * UPDATE AT 1317 EDT ON 09/10/12 FROM DEREK DROCKELMAN TO S. SANDIN * * *

| Event Text POTENTIAL PART 21 ISSUE RELATED TO TYCO TIMING RELAY
The following information was provided via facsimile:
"QualTech NP is providing this notification as a potential 10 CFR Part 21 issue. We have discovered a manufacturing defect in a timing relay which prevents the relay from operating at a specific setting. This relay was purchased as a commercial grade item and dedicated through our dedication process for safety related applications at our Cincinnati facility.
"The subject equipment is TYCO Model CNT-35-96, a timing relay with adjustable trip ranges from seconds up to 9,990 hours. QualTech NP has recently identified a failure mode for this relay in that the device will not trip in the 10H setting. In communications with the manufacturer, they have confirmed that there is a flaw in the design that prevents this specific setting from tripping.
"QualTech NP has only sold this unit to two plants, both Exelon. We recognize, however that other utilities could have these installed. Based on the information in hand we are evaluating the need for a 10 CFR Part 21 notification. Since the item was qualified under the EPRI SQURTS [Seismic Qualification Reporting and Testing Standardization] Program, the recommended corrective action is to notify EPRI of the condition in order for SQURTS members to perform an impact evaluation.
"Additional details will be provided in the formal written report. Please contact Tim Franchuk at 513-528-7900, ext. 176 (office), [redacted] or via email tfranchuk@curtisswright.com for any additional information."
* * * UPDATE ON 8/2/12 AT 1659 EDT FROM MARGIE BREWER TO DONG PARK * * *
The licensee has revised the third paragraph to read as follows:
"QualTech NP has only sold this unit to two plants, Exelon LaSalle and Quad Cities. We recognize, however that other utilities could have these installed. Based on the information in hand we are evaluating the need for a 10 CFR Part 21 notification. Since the item was qualified under the EPRI SQURTS [Seismic Qualification Reporting and Testing Standardization] Program, QualTech NP recognizes that other SQURTS members may have used the qualification basis as part of licensee dedication activities, and therefore, will notify EPRI of the condition."

The following information was obtained from the state of Mississippi via email:
"DRH [Mississippi Department of Radiation Health] was notified on 8/27/2012 by Licensee's RSO regarding a stuck source incident that occurred on 8/24/2012 while performing industrial radiography at a temporary job site in Mississippi.
"The RSO claims the camera (880D) fell onto the guide tube during one of the shots and crimped the guide tube preventing the source from retracting back into the camera. The RSO suspects the technician may have pulled on the cranks while trying to crank back in the source after the shot. This could have then caused the camera to fall onto the guide tube and crimp it.
"The restricted area boundary was readjusted to one (1) mR/hr, maintained, and the RSO was called by the radiographers at the job site. An ARSO and technician from the company who are trained in source retrieval arrived at the job site and retrieved the source. The camera was wiped and leak tests were submitted for analysis.
"The Licensee's ARSO received 82 mR and the technician received 8 mR/hr from actions taken during the source retrieval."

The following information was received from the State of Nevada via email:
"A graduate student inhaled a mixture of U-233 and U-238 while working in the lab grinding a compound of Uranium Octoxide. [The graduate student] used a glove box instead of the hood with the HEPA filter, contrary to UNLV [University of Nevada Las Vegas] approved procedure.
"This happened twice and could have been between October 1, 2011 and April 1, 2012.
"The first bioassay, based on an inhalation date of October 1, 2011, showed 17.72 rem total. When the inhalation date was assumed to be April 1, 2012, the result was 5.52 rem.
"[U-233]*1.6 = [U-238] contribution.
"The student will be getting a third bioassay on September 5, 2012 at the Lawrence Livermore National Lab (LLNL). This will involve a low-energy chest count to detect Th-234 and an organ count, looking at the kidneys for Uranium.
"The student has been restricted from all lab work since April.
"The bioassay was done at Test America." |

"At 0900 CDT on September 10, 2012, the Unit 1 Plant Process Computer (PPC) was removed from service for a planned replacement in the current Unit 1 Refueling Outage. The Unit 1 PPC feeds the Safety Parameter Display System (SPDS) used in the Main Control Room (MCR) and the Technical Support Center (TSC). The Unit 1 PPC also feeds the Emergency Response Data System (ERDS).
"The Unit 1 and Unit 2 PPCs also feed the Plant Parameters Display System (PPDS) used in the MCR, TSC and Emergency Operations Facility (EOF). Meteorological data will remain available. The dose assessment program will remain functional as the Unit 2 PPC will be capable of providing the necessary data through PPDS to run the program. The dose assessment program is not affected by the Unit 1 PPC being out of service. As compensatory measures, a proceduralized backup method to fax or communicate via a phone circuit applicable data to the NRC, TSC, and EOF exists. There is no impact on the Emergency Notification System (ENS) or Health Physics Network (HPN) communication systems.
"The new Unit 1 PPC is scheduled to be functional on September 17, 2012. However, based on the Mode Unit 1 will be in, this will limit the number of points that would provide usable data. The Unit 1 PPC will be tested as Mode changes occur. The Unit 1 PPC is planned to be declared functional by Mode 2. A follow-up ENS call will be made once the Unit 1 PPC is declared functional.
"The loss of SPDS and ERDS is a 'major loss of assessment capability' and is reportable under 10CFR50.72(b)(3) (xiii).
"The NRC Senior Resident Inspector and the State of Illinois (through the Illinois Emergency Management Agency Resident Inspector) have been notified of this ENS call." |

"Unit 1 and Unit 2 entered LCO 3.0.3 due to both Control Structure (CS) chillers 'A & B' concurrently inoperable.
"At 1025 [EDT], the control room was notified that the 'B' CS Chiller was not running. There were no control room alarms due to this condition. Review of indications on control room panel 0C681 noted that the loop circ pump and all three CS fans remained in service. Indication of CS loop flow and loop temperature remained normal, approximately 600 gpm and 44 degrees.
"The 'B' CS Chiller restarted at 1027 [EDT] and normal system parameters were observed.
"Work on the 'A' CS Chiller was released at 0928 [EDT] on 9/10/2012 for scheduled maintenance, LCO's 3.7.3 and 3.7.4 were entered, however no work had actually commenced or was performed. The 'A' CS Chiller remained available and in standby during the entire evolution.
"Since the cause of the 'B' CS Chiller to shutdown has not been determined, the 'B' CS Chiller was declared inoperable. Inoperability of both CS chillers 'A & B' required immediate entry into LCO 3.0.3 per TS 3.7.4 Condition D. Both chillers were inoperable from 1025 [EDT] until 1042 [EDT] (17 minutes), when the 'A' CS Chiller was restored to operable status.
"This condition is being reported as an event or condition that could have prevented fulfillment of a safety function per 10CFR 50.72(b)(3)(v)(D)."
