Subject:
fyi - TMI contamination event fyi - The Pennsylvania Gov Rendell is asking the NRC Chairman some questions about the TMI contamination event, and the Chairman needs answers today. The Chairman evidently asked Rg I John White/Sam Collins for the answers. Rg I is asking us to support getting answers Questions:
- 1. What are the notification protocols? 10CFR 50.72. In this case, 10 CFR50.72(b)(2)(xi).
- 2. How many contamination events are normal? The licensee had developed performance goals of less than X PCE. (Get X from Ron.) The number of contamination events during a RIFO will depend on the types of maintenance activities performed during the outage. A typical number of contamination events for a S/G replacement may be on the order of 10 to 20 PCEs.
- 3. How many workers are exposed (normally)? In a typical RFO, the typical worker entering the containment building receive some exposure, but all exposures are typically less than the NRCs limits for occupational workers.
- 4. How many workers dose exceed 2 rem normally? Only a very small fraction (significantly less than 1% of the occupational workers) receive exposrees in excess of 2 rem annually.
