As I was throwing away my no longer useful, handwritten comments on the SONGS replacement steam generators, I noticed a problem that I do not believe has been addressed by the Nuclear Regulatory Commission.
According to my notes, the SONGS AIT report, (ML12188A748), describes about 30 "valid" vibration and loose parts alarms at San Onofre. My recollection is that these alarms were described as valid although no cause had been identified for any alarm.
Does it make sense to keep in service, inaccurate PWR monitoring equipment?
Thank you, Tom Gurdziel On page 22 of the referenced report, you will find that all the alarms apparently occurred between February 18, 2011 and January 31, 2012. (This would not be even one complete year.)
Is there any NRC group responsible for seeing that PWR nuisance alarms get addressed? Is there any recommended response time?
