"As part of an extent of condition review related to ENS report 50362 (Unanalyzed Condition Due to Lack of Appropriate Fuse Protection), it was identified that, within the past three years, three additional examples existed of missing fire barriers that could have impacted separation of redundant safe shutdown trains. For the affected areas associated with each of the three missing barriers, compensatory measures (hourly fire watches) had been in place for three years prior to the discovery of the condition. However, it was determined the missing barriers met the reporting criteria for 10 CFR 50.72(b)(3)(ii)(B) as unanalyzed conditions that significantly degraded plant safety.
"The first condition was the use of rodofoam material in Auxiliary Building seismic joint seals. Rodofoam is a combustible foam material and does not provide a fire rating equivalent to the barriers in which it was used. This issue was corrected in a plant modification.
"The second condition is the lack of required fire dampers in ventilation supply ducts to the Aux. Feedwater (AFW) Pump Rooms (Fire areas 31 and 32). An engineering change package has been approved to implement a plant modification to install the required dampers as part of the NFPA-805 transition.
"The third condition is a gap where the ventilation duct passes through the wall from the Bus 150/160 room into the AFW pump room. An engineering change package has been approved to implement a plant modification to correct this condition as part of the NFPA-805 transition.
"The protection of the health and safety of the public was not affected by this issue. In all cases, compensatory measures existed to ensure the protection of safe shutdown equipment.
"The licensee has notified the NRC Senior Resident Inspector."
* * * UPDATE FROM DOUG LARSON TO DANIEL MILLS AT 2122 EST ON 11/18/14 * * *
"Northern States Power Company (NSPM) has determined that the missing fire damper and the wall gap (the second and third identified conditions) are not separating redundant equipment and no longer meet the regulatory definition of an unanalyzed condition. This was identified when it was determined that the redundant pressurizer heater cables credited for safe shutdown were routed through the same fire area. This was reported under EN 50531 (Unanalyzed Condition Due To Missing Fire Barrier). Since the missing fire barrier does not separate redundant equipment, the condition does not degrade plant safety, and is no longer reportable.
"The protection of the health and safety of the public was not affected by this issue.
"The licensee has notified the NRC Resident Inspector."

"During a Fire Penetration walkdown, an opening less than 1 [inch] tall under a duct was identified between the Train B Aux Feedwater Pump (AFWP) Room (Unit 1 side) and the Bus150/160 room. This constitutes a missing fire barrier between Fire Area (FA) 32 and FA 37 such that the required degree of separation for redundant safe shutdown trains is lacking.
"A firewatch has been established on the Unit 1 side of the AFWP Room and Bus 150/160 room. The compensatory fire watch will remain in place per F5 Appendix K until the fire barrier is returned to full functional status.
"The discovery of this non-compliance is being reported as an unanalyzed condition as defined by 10CFR50.72(b)(3)(ii)(B).
"The protection of the health and safety of the public was not affected by this issue.

PART 21 GROUP (EMAI)
| Event Text 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. |

"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 'C' accumulators to operable (breakers opened and locked with their associated outlet valves open). | |
