UNANALYZED CONDITION DUE TO ALL FOUR SAFETY INJECTION ACCUMULATORS INOPERABLE
"Following shift turnover from days to nights on 11/18/2014, it was discovered that all (4) of the Safety Injection (SI) Accumulator Outlet Isolation Valve breakers were unlocked and closed. At the time of discovery, 3 of the safety injection accumulator valves were open and 1 was closed for testing. At that time the plant was in MODE 3 at normal operating pressure and temperature. The plant had been performing RCS pressure isolation valve testing prior to shift turnover. The condition was discovered during testing of valves associated with the 'C' safety injection accumulator.
"After discovery of the condition, Operations directed that the 'A', 'B', and 'D' SI Accumulator Outlet Isolation Valve breakers be opened and locked. This action was completed by approximately 1930 [CST] on 11/18/2014.
"The NRC Resident Inspector was notified."
The plant entered T.S. 3.0.3 for approximately 30 minutes while restoring the 'A', 'B' and 'D' accumulators to operable (breakers opened and locked with their associated outlet valves open).

SECONDARY CONTAINMENT INTERLOCK DOORS OPEN SIMULTANEOUSLY
"On November 18, 2014, at 0900 [CST], the Shift Manager was notified that two Secondary Containment interlock doors were open simultaneously. The doors were immediately closed and Secondary Containment pressure remained negative throughout the event.
"This condition represents a failure to meet Surveillance Requirement 3.6.4.1.2 given two doors in a single access opening were open. As a result entry into Technical Specification 3.6.4.1, Condition A, was made momentarily due to Secondary Containment being inoperable.
"This event is reportable under 50.72(b)(3)(v)(C) as an event or condition that could have prevented the fulfillment of a safety function.
"The NRC Resident Inspector has been notified."
The State of Illinois has been notified.

PART 21 - LACK OF PROPER POWER SUPPLY INDICATION
The following information was summarized from the report obtained from the vendor via facsimile:
Technology for Energy Corporation [TEC] has determined that the Model 1414 Valve Flow Monitoring Systems power supply may not provide proper output voltage contrary to power supply status indicators on the rack. This may result in the power supply not providing necessary power to its associated input sensor. A subsequent loss of the sensor output would result in the inability of the system to indicate any valve flow. Depending on the specific configuration, signals from more than one sensor could be lost on a single failure.
This Model 1414 system design dates back to 1979. TEC has not been made aware of any instances of the described failure mode in the 35 year history of the product design, suggesting that the robustness of power supply design and the users periodic maintenance of the system has provided for acceptable continued operation.
The potentially affected plants include Clinton Unit 1; Comanche Peak Units 1 & 2; Nine Mile Point Unit 2; Palo Verde Units 1, 2, & 3; River Bend Unit 1; Susquehanna Units 1 & 2; Watts Bar Units 1 & 2.
* * * UPDATED FROM DONNA MULLALY TO DONALD NORWOOD AT 1329 EST ON 11/24/2014 * * *
After submitting the original Part 21 notification, TEC discovered that Columbia Generating Station had been omitted from the list of affected plants.
"The following correction should be applied: The potentially affected plants include Clinton Unit 1; Columbia Generating Station, Comanche Peak Units 1 & 2; Nine Mile Point Unit 2; Palo Verde Units 1, 2, & 3; River Bend Unit 1; Susquehanna Units 1 & 2; and Watts Bar Units 1 & 2."
