 Junk Plant RIver Bend: Following Grand Gulf Into The "Not Following" Procedure Abyss

Basically three "slap on the wrist" procedure violations at River Bend this inspection cycle. How prevalent is bum procedures in River Bend??? It just might be River Bend is maliciously not following procedures to inflate profits or minimize losses?

Green. The inspectors identified a non-cited violation of Technical Specification 5.4, “Procedures,” for the licensee’s failure to follow station maintenance procedures related to the control of scaffolding in the reactor building. Specifically, the licensee installed scaffolding less than two inches from safety-related containment unit cooler HVR-UC1B without completing an engineering evaluation. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2016-07963. Corrective actions included removing the scaffolding.

Green. The inspectors identified a non-cited violation of Technical Specification 5.4, “Procedures,” for the licensee’s failure to properly pre-plan and perform maintenance on safety-related components in accordance with documented instructions appropriate to the circumstances. Specifically, the licensee used work order instructions that did not contain sufficient detail for the reassembly of SWP-PVY32C, a safety-related valve in the control building ventilation system. As a result, SWP-PVY32C developed a refrigerant leak, and on November 17, 2015, the valve failed. This in turn caused the control building ventilation system to fail, and the high pressure core spray system was consequently declared inoperable. The licensee entered this condition into their corrective action program as Condition Report CR-RBS-2017-02364. Corrective actions included incorporating the torque values into the model work order instructions for future maintenance and reassembly.


Green. The inspectors identified a non-cited violation of Technical Specifications 3.8.4, “DC Sources - Operating,” 3.8.7, “Inverters – Operating,” and 3.8.9, “Distribution Systems – Operating,” for the licensee’s failure to either restore inoperable electrical power subsystems, inverters, and distribution subsystems to operable status within the applicable completion times, or be in Mode 3 in 12 hours and Mode 4 in 36 hours. Specifically, electrical power systems required by the above limiting conditions for operation were inoperable due to the associated division of the control building chilled water system chillers being out of service and therefore unavailable to provide the technical specification support function of attendant cooling that is needed for the associated electrical systems to perform their specified safety functions. As a result of this deficiency, the station reduced the reliability and availability of systems cooled by control building chilled water system chillers by allowing configurations that did not conform to the single failure criterion. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2015-02525. Corrective actions included entering the appropriate limiting conditions for operation of affected safety-related systems when the non-safety related support system were non-functional.
