Diablo Canyon does latch the dose rate alarm. We changed our process after our Fuel Handling Building event in 2012. Briefly, the workers did not hear their rate alarms because of all the other rad monitors alarms that sounded. The workers got a fuel bundle too close to an open Weir gate and the empty transfer canal. They recognized the situation when a number of rad monitoring devices went into alarm and moved the bridge back. Because all the alarms cleared the magnitude of the event was not recognized until RCA logout. The spotters ED indicated a rate alarm of approximately 2200 mR/hr.
Please take a look at our OE on this event. It presents a compelling case for latching the dose rate alarm.

We have DMC 2000s (eventually going to 3000s), and currently latch for accumulated dose only. Thank you in advance for your time and consideration!
