For a long time Palo Verde checked all LHRA locks shiftly, however per Reg. Guide 8.38, 1.2.5 Verification of Controls we changed this periodicity to weekly (during non-outage periods) we nevertheless retained the once per shift check during outage periods. We typically do not incur any dose was performing on-line LHRA checks.
From: [email protected] [mailto:[email protected]] On Behalf Of Creamer, Charles E Sent: Friday, November 11, 2011 12:51 PM To: [email protected] Subject: Powernet: LHRA door check Browns Ferry currently conducts a weekly walk down of our Locked High Radiation Area Doors. Based upon the use of secondary locking devices and second party checks when securing an area we are looking at reducing this frequency to biweekly. What frequency do you check your locked high rad doors? Being a 3 unit BWR, we have about 100 of these doors so this can be a dose saving measure. ___________________________ Chuck Creamer Charles E.
