OK I'm glad we all agree but that doesn't mean that our PCE classifications bear any relationship to importance or risk significance. Why couldn't we have Level 1 begin at 1000 ccpm on shoes, 500 ccpm on external clothing, 200 ccpm on skin, and 100 ccpm on the face? Wouldn't that make more sense?

Another point to make, in case it comes up, is that the industry agreed with these definitions – so wasn’t just INPO coming up with the definitions. Dane R. Williams, CHP Organizational Effectiveness Team Leader Institute of Nuclear Power Operations [email protected] 770.644.8882 From: [email protected] [mailto:[email protected]] On Behalf Of cindy connelly Sent: Tuesday, October 19, 2010 8:14 AM To: [email protected] Subject: Re: Powernet: PCE Question INPO position: It is still a level 1 PCE if inside of the clothing is less than level 1 criteria but outside meets level 1. This is very important to provide consisitency in reporting/trending of the additional indicators. These are the definitions from the Data Element Manual. Total Contaminated Personnel 8.4.1 This is a unit level data element. Data is entered for each unit at a station. The number of occurrences in each month in which an individual was contaminated (≥100 cpm above background) on skin, clothing or modesty garments. This is a count of the number of logged occurrences (Action Level 1, 2, and 3) in accordance with EPRI guidance. Refueling Outage Contaminated Personnel 8.4.2 This is a unit level data element. Data is entered for each unit at a station. The number of occurrences during a refueling outage in which an individual was contaminated (≥100 cpm above background) on skin, clothing or modesty garments. This is a count of the number of logged occurrences (Action Level 1, 2, and 3) in accordance with EPRI guidance. In months in which no refueling outage has occurred the value field should be left blank with a status of "Final". If you have any questions, please give us a call. 770-644-8839.

Been recommended to me that EPRI guidance (excerpted below) is interpreted as suggesting that approach at some benchmark plants. The determination of the EPRI PCE level classification should be based on a frisker reading of the skin or the highest reading on clothing. For skin contaminations, a frisker reading should be the maximum reading with the frisker held approximately ½ inch away from the affected skin. For clothing, the frisker reading should be on the inside of the clothing with the detector faced away from the skin.
