AGREEMENT STATE REPORT - STOLEN TROXLER GAUGE
"A gauge was stolen on Sunday night, October 12, 2001. The RSO learned of the theft today. The gauge was a Troxler Model 3430, serial number 28502. The sealed sources were as follows: a 40 millicurie Am-241/Be, serial number 4725568 and an 8 millicurie Cs-137 source, serial number 7502724.
"The gauge was taken from the back of a truck at a residence. It was in its case which was stolen along with other equipment on the back of the truck. The case was probably not secured or locked to the truck. The source rod was probably locked. A police report is being made. Also DOT is being contacted by the Licensee.
"The Licensee will submit a written report within thirty days".

PACKAGE CONTAINING PHOSPHOROUS-32 WITH EXTERNAL RAD LEVELS GREATER THAN LIMITS
The Washington Hospital Center received a package from Isotex Diagnostics Incorporated(Texas lic # L02999) of Friendswood, Texas that measured on surface contact 48 Rads/hr using an ion chamber with the beta shield off. This was over a small area of the package. At one meter with the beta shield off it measured 77 millirads/hr. Both the shipper and the carrier(FedEx) have been notified. The package contained 92.8 millicuries of phosphorous-32 with packing label yellow-2 and transport index 0.6. There was no contamination detected. They are holding the package for inspection by the shipper.

DISCOVERY OF A THROUGH-WALL LEAK AROUND 8 THERMOCOUPLE NOZZLES (REACTOR COOLANT SYSTEM PRESSURE BOUNDARY LEAK)
On October 11 and 12, 2001, following shutdown for a scheduled refueling outage, three Mile Island Unit 1 (TMI-1) performed a visual inspection of the Reactor Vessel (RV) Thermocouple (TC) nozzles per NRC Bulletin 2001-01. The inspection revealed evidence of boric acid buildup around all eight (8) TCs nozzles. At approximately 1230 on October 12, 2001, Engineering evaluation of the visual inspection results confirmed that the boron deposits around the eight TCs indicate a Reactor Coolant System (RCS) pressure boundary leak. This condition is consistent with industry experience with Primary Water Stress Corrosion Cracking (PWSCC) in reactor vessel head nozzles that have been evaluated as part of the NRC Generic Letter 97-01 and NRC Bulletin 2001-01. TMI-1 plans to perform repairs during the current refueling outage. Since the condition resulted in leakage through the RCS pressure boundary, it is being reported as a non-emergency [8-hour] report in accordance with 10 CFR 50.72(b)(3)(ii)(A) and 50.73(a)(2)(ii)(A).
Results from the CRDM nozzle inspection have not yet been submitted.
The NRC resident inspector has been notified.
