I Update on the plant

1. The licensee has completed the whole body count of about 150 workers in containment. 20 of these workers had estimated between 10 mrem and 36 mrem. 5 of these workers initially show higher doses, but th results are suspect and are being evaluated.
2. The licensee continues to maintain a tarp on the containment hole for the SG replacement.
3. Two potential causes of the airborne contamination event are being reviewed. The first is associated with welding activities on a small plug inside the skirt on the bottom of the B SG, during which the associated HEP filter which is powered via an extension cord was found tripped. The other is pipe decontamination and preparation activities associated with the A cold leg, which they identified high contamination on the outside of a wet vac located near the work.
4. Both these two activities are located in the D ring. The license has maintained a hold on work in these areas, as they continue to assess the cause and clean up areas of high containment.
