----- Original Message ----- From: ajsekel Sent: 05/25/2011 02:46 PM AST To: [email protected] Subject: Re: Powernet: MDC vs. Critical Level DC Cook does the following. Does your site use: DL? DA? MDA? CL? LD? LC? LLD? MDC? ABC? 123? DC Cook uses MDA for Alpha and Beta counters. Specifically the Ludlum 3030P and the Canberra S5E. Also, procedurally we assume the LLD is the same as the MDA. What are your technicians expected to calculate? Since the Ludlum 3030P and the Canberra S5E calculate the MDA through internal firmware, the technicians are not required to calculate anything. How do you define these mathematically – what formulas do you use for each? If you need the individual formulas that the instruments calculate, just let me know and I can provide you with them. What is your basis – that is, what is the regulation you point to for your basis? EPRI document 1013509 is used for alpha guidance. The Pland ODCM is used for LLD calculation.
