Yes 1. 144 hours (best ever is 128, best ever for offload-CEA shuffle-reload is 144) 2. 217, 89 CEAs 3. 217 + 92 = 319 fuel, 89 CEA 4. Yes, we have a dual masted refuel machine - one for CEAs and one for fuel (including a fuel assembly with a CEA in it) Clint Alday Waterford 3 -----Original Message----- From: respvr-bounces(a)retaqs.com [mailto:respvr-bounces@retaqs.com] On Behalf Of Fago, Carl D Sent: Friday, December 07, 2007 8:37 PM To: respvr(a)retaqs.com Subject: [Respvr] PWR Core Reload Question Some questions for the PWR folks: Do you perform in-core shuffle for reloads? If yes ... 1. How much time is normally scheduled for in-core shuffle? 2. How many FA in your core? How many components (burnable poisons, control rods, sources, thimbles, etc.)? 3. Roughly, how many individual assembly or component moves is your normal reload? 4. Do you have an installed mast for components (I've heard that some use a temporary component mast installed each outage)? Thanks! Carl Carl D.
