Ameren Missouri is disputing a violation it obtained for its Callaway County Nuclear Plant, following a September U.S. Nuclear Regulatory Fee inspection.
The NRC launched the inspection outcomes Oct. 12. The inspection was an issue identification and backbone inspection. The inspection crew examined the plant to “consider its effectiveness in figuring out, prioritizing, evaluating and correcting issues,” based on the NRC report. The inspection crew additionally confirmed NRC rules had been being adopted.
The disputed violation is a non-cited violation associated to “the failure to carry out required in-service testing of air-operated residual warmth elimination warmth exchanger outlet and bypass valves,” based on an NRC doc.
The violation alleges the Callaway plant didn’t carry out required testing for 4 pneumatically operated valves. This can be a results of incorrectly classifying them as passive valves, based on the NRC report.
A pneumatically operated valve, also called an air-operated valve, is outlined by Humphrey Merchandise as a valve that makes use of air strain to managed compressed air, liquids or fuel with a pneumatic system.
A passive valve is outlined in a Micromachines journal article as an “various answer for efficient move management in a microfluidic system, and it often depends on a microchannel construction or pure impact to control the move charge.”
Within the September inspection report, the NRC inspection crew recorded three non-cited violations. All three had been of “very low security significance,” based on the NRC’s report.
The NRC crew mentioned the findings with members of the Callaway plant workers. NRC is reviewing if the violation will be disputed. A choice will probably be reached inside 90 days of Nov. 14.
