AGREEMENT STATE REPORT - LOST MOISTURE DENSITY GAUGE

"Licensee's case containing gauge [Troxler Moisture Density Gauge, Model 3411-B, Serial Number 18168, 8 millicuries Cs-137, 40 millicuries Am-241:Be] fell out of a truck while driving down the road. A fire truck just happened to be following the truck and secured the gauge. The technician noted loss and returned to the scene. Gauge and case were not damaged. The technician forgot to chain the gauge to the truck after finishing a job. The licensee will submit a written report on this incident."

A SIGNIFICANT REDUCTION IN THE EFFECTIVENESS OF ANY SPENT FUEL OR GTCC WASTE STORAGE CONTAINMENT SYSTEM DURING USE.

"A significant reduction in the effectiveness of any spent fuel storage confinement system during use "

"This reportability notification addresses a potential unanalyzed condition of 18 Transportable Storage Canisters (TSCs) which are loaded with spent nuclear fuel (SNF). Seventeen of these TSCs are stored in Vertical Concrete Casks (VCCs) at the Haddam Neck Plant Independent Spent Fuel Storage Installation (ISFSI). One TSC is currently in transport operations and will be transferred to the ISFSI in the near future.

"SNF clad temperature is affected by changes in the TSC internal environment that are encountered during fuel transfer operations. In order to maintain SNF clad temperatures within the analyzed limits, the time duration of certain fuel transfer activities are limited (for example, time in dewatering phase, time in vacuum drying phase and time in helium backfill phase).

"The canister dewatering section of CY procedures allowed multiple blowdowns of the TSC while in the dewatering time clock. This is contrary to the NAC thermal analysis which assumes a water environment in the canister during the dewatering period. It appears that this condition is not consistent with current analysis assumptions and is therefore a potential unanalyzed condition.

"NAC International (holder of the C of C) has been advised of this condition and is analyzing the TSC loading conditions. VCC outlet temperatures are within acceptable limits and there is no evidence of unusual radiation exposure in the ISFSI environs."

CRACKS/FISSURES IN POWER AIR PURIFYING RESPIRATORS (PAPR) MOTOR/BLOWER ASSEMBLY CASINGS



"Exact content of notification: Battelle is notifying NRC of a potential defect as from the manufacturer
concerning the MSA equipment provided Model MM2K PAPR motor/blower assembly (Part 10022695). After limited field use at its West Jefferson, Ohio site noticeable cracks/fissures developed on some of the motor/blower casings. The manufacturer of the equipment, MSA, has been notified of the problem and several of the cracked/fissure units have been returned to MSA for testing in early September. Battelle discontinued use of the MSA Model MM2K PAP'R in mid September as a result of the observed equipment cracks/fissures at its West Jefferson, Ohio site.

"Describe the event: We have been experiencing noticeable cracks/fissures of some of our MSA brand MM2K Powered Air Purifying Respirators (PAPR) motor/blower assembly casings (Part #10022695). We have not experienced any break through of the casings tied to employee exposure as evidenced by our In place personnel monitoring programs. Our original note of the circumstance was on August 25, 2004 during the re-use inspection process of the MSA MM2K PAPR by the Respiratory Protection Supervisor on site. We have field verified that our respirator cleaning and use processes are adequate and in line with the manufacturer recommendations. We again experienced a similar crack/fissures Issue with a different order of MSA MM2K PAPR motor/blower assemblies by a different vendor ordering from a different lot number in early September 2004. We have discontinued use of the MSA MM2K PAPR on site in mid September as a result of the issues we have had and have supplied MSA with several of the cracked/fissured MM2K PAPR motor/blower assembly casings for testing at their facility In Pennsylvania. MSA Is working on a solution for the identified issue.
