LOST RADIOACTIVE MATERIAL FOUND IN SCRAP YARD
"Material received at scrap yard on August 5, 2008. Wisconsin DHS verified via phone that material was locked in a secure location from members of the public. On August 7, 2008 DHS investigated the radioactive material, a compacted 55 gallon drum with multiple pieces of scrap inside drum. A mini-spec GR-135DN was used to determine the source of radiation as Ra-226. Radiation exposure and contamination surveys were conducted on the outside of the compacted drum. The maximum exposure observed was 500 uRem/hr. The contamination survey on the drum found no contamination. DHS staff tried to locate the source of radiation inside the drum where the highest radiation levels were located. During the attempt, several pieces of scrap were removed and surveyed and no radiation above background except for one piece that read above background. Material was properly tagged and bagged. The staffs gloved hands were frisked and contamination was present. Individual doffed gloves and re-performed hand frisk and no contamination was found. The staff halted any further handling activities at this time to prevent any possible spread of contamination. The material was properly tagged, bagged and stored at the scrap yard in a locked holding area that is not accessible by members of the public. DHS is exploring options to properly dispose of this radioactive material."
State Event Report: WI080008
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source

TECH SPEC REQUIRED SHUTDOWN DUE TO EXCESSIVE UNIDENTIFIED LEAKAGE
"On August 5, 2008, a planned shutdown was in progress to repair a control rod drive mechanism due to excessive leakage (within Tech Spec identified leakage limits). During the shutdown, the site experienced excessive unidentified leakage of approximately four gallons per minute for short periods following charging pump starts, due to leakage past the letdown relief valve. [this first occurred at 1629] As a result of the plant shutdown, and not being in a steady state condition, PCS leakage is unable to be definitively determined. Limiting Condition of Operation 3.4.13 was entered at 1629 hrs. The plant was in Mode 3 at 1955 hrs. The Tech Spec requirement is to restore leakage to within limits within 4 hours. If not within limits within 4 hours, be in Mode 3 within 6 hours (August 6, 2008 at 0229 hours) and be in Mode 5 within 36 hours (August 7, 2008 at 0829 hrs). This event is being reported as a 4-hour non-emergency report in accordance with 10 CFR 50.72(b)(2)(i), Tech Spec required shutdown."
The licensee will notify the NRC Resident Inspector.
