Braidwood does not have alpha spec. We currently use Ludlum 3030P and the Tennelec prop counter
Amanda L. Stenson Exelon Corp - Braidwood NPS RP Technical Specialist (815)417-2712 ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Holmes, Stephen J:(Constellation) Sent: Friday, May 04, 2012 11:41 AM To: '[email protected]' Subject: Powernet: Benchmark: Alpha Spec At Ginna, we are evaluating purchasing Alpha Spec equipment (such as the Canberra Alpha Analyst with Alpha Apex software). Part of our justification for this expense would be to reduce our reliance on independent laboratories for performing alpha characterization (i.e. per the EPRI alpha monitoring guidelines). We currently have Ludlum 3030Ps and MGPI ABPMs which use alpha spec in a limited manner to perform radon rejection, but no true alpha spectroscopy equipment. We would like to know what the rest of the industry is doing; any experience, comments, or feedback are appreciated. Do you have Alpha Spec capabilities at your facility? If so, what equipment do you use? What do you use the equipment for (e.g. radon rejection or a quantitative alpha spectrum of individual nuclides)? If using for alpha spectrum analysis, what energy resolution can you achieve? What type of sample preparation is required? Any other equipment strengths/limitations or lessons learned you would like to share?
