AGREEMENT STATE REPORT - QSA GLOBAL REPORT OF DEFECT

"On January 8, 2010, at 1552 hrs. EST, QSA Global, Inc. reported a product defect to the Massachusetts Radiation Control Program in accordance with 105 CMR 120.142(B)(2)(a). The affected equipment that was identified was the QSA Model 87703 source assembly for a QSA Global radiography camera. A customer had received a Model 87703 source assembly and reported problems with the assembly connection on October 21, 2009. The unit was returned to their Burlington office and QSA Global, Inc. performed an evaluation of the extent of the defect. The Model 55000-3 female connector sleeve was identified as the source of the problem.

"The defect causes the male connector to not be fully seated in the sleeve of the connector and it was, therefore, not locking in. This could give the user the false impression that the source is connected to the drive cable when there is only a partial connection. The operations manual requires that the user visually check the connection prior to use. If the user does not do a full visual inspection of the connection, the source assembly may not be secure and could dislodge inside guide tube.

"The manufacturer conducted a 100% search of a lot of 1,567 pieces in stock and found 5 to be defective. The manufacturer is sending out notice dated January 11, 2010 to all of their radiography customers describing this disconnect issue. There are 236 sources in the field with 29 different licensees that have not sent their units back to QSA Global in Burlington, MA at this time. They will continue to monitor this problem as assemblies are returned."

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO CONTROL ROOM CHILLERS OUT OF SERVICE

"The A-YC chiller [was] shutdown and tagged for yearly inspection and work. The B-YC chiller has developed a refrigerant leak and has been declared inoperable. This places both Unit 1 and Unit 2 in Tech Spec 3.0.3. Both units will have to be in Mode 3 within 7 hours; Mode 4 within 13 hours; and 37 hours to be in Mode 5. 3.0.3 was declared at 2332 on 1/12/2010. The event time is when Unit 1 began load reduction. Unit 2 will commence load reduction at 0230."

The licensee notified the NRC Resident Inspector.

WRONG TRAIN OF EMERGENCY CORE COOLING SYSTEM REMOVED FROM SERVICE

"On January 13, 2010, at about 1125 PST, Train A suction piping from the SONGS Unit 3 Refueling Water Storage Tank (RWST) was determined to be inoperable following detection of weld flaw indications during ultrasonic testing. Due to miscommunication, operators mistakenly declared the Train B Emergency Core Cooling System (ECCS) header inoperable at about 1125 and removed DC control power to the Train B ECCS pumps. This resulted in both trains of Unit 3 ECCS being inoperable and entry into the Technical Specification (TS) 3.0.3 one-hour shut down action. At 1140 PST, the DC control power was restored to the Train B ECCS pumps, Train B ECCS was declared operable, and TS 3.0.3 was exited. SCE is reporting this in accordance with 10 CFR 50.72(b)(3)(v) as an event that could have prevented the fulfillment of a safety function.

"SCE is further evaluating the indications found on Train A piping to determine if the piping is capable of performing its safety function. At the time of this occurrence, Unit 2 was in a Steam Generator Replacement Outage, and Unit 3 was at approximately 100% power."

The licensee notified the NRC Resident Inspector.
