In Steam affected Areas Browns Ferry only performs surveys as needed for entry. Hopefully the entry is not at 100%. We do not survey these areas on a routine basis just to have a survey of them.

Sent: Wednesday, May 18, 2011 9:38 AM To: [email protected] Subject: Powernet: 100% power steam affected surveys Cooper Nuclear Station has the following question concerning BWR 100% power steam affected area surveys. CNS currently performs a 100% power survey post outage and accumulates approximately 200 mrem, and the question was posed do we need to perform this survey? At what frequency does you plant perform steam affected area 100% power surveys? Do you post the areas survey required prior to entry or do you do surveys on some frequency (semi-annual, annual, post outage 100% power?)
