AGREEMENT STATE REPORT - UNATTENDED RADIOGRAPHIC EXPOSURE DEVICE

The following report was received from the State of Ohio via email:

"On 12-11-2015, at 1738 EST, a radiographic exposure device was left unattended by licensee personnel and found by a customer's employee.

"Licensee's investigation indicated that their crew had performed 2 exposures at 2 minutes and 30 seconds on each exposure. Customer operations wanted to get their nuclear gauges back online as soon as possible so when the last exposure was complete the radiographer sent the assistant to let [the Customer] operations know they were complete. The radiographer then broke down everything and picked up the assistant [radiographer] at the ops building. They then drove back to the trailer where the radiographer went to the smoking area and the assistant went to the restroom. When the assistant came out they both went to back of the vehicle to grab film and they realized that the source was not in the vehicle. They immediately drove back to the area.

"While enroute back to the location of the radiography work they received a phone call from the customer's project manager that an employee had located an unattended exposure device. When the crew arrived, they determined the device was in the same place where they left it and the device was locked. Estimated time that the device was unsecured was 15 minutes. They surveyed the device, secured the device in the vehicle, and went back to the trailer. The licensee left a voice mail at ODH [Ohio Department of Health] at 1819 EST describing the situation.

"There was an immediate safety stand down put in place and no further exposures were to be made. On Saturday morning, 12/15/15, there was a conference call made at 0706 EST to the licensee's crews that were working. The crew that was involved in the incident were suspended from any radiographic work until a full investigation was made.

"On 12-14-2015, the [licensee's] RSO [Radiation Safety Officer] conducted a site visit and there was another safety meeting held with all crews on site.

"The exposure device was an 880 Delta made by QSA, the device contained 33.2 curies of IR-192, the source was made by QSA, model number 424-9.

"A more detailed report is expected from the licensee."

Ohio State NMED Report: OH150013

THIS MATERIAL EVENT CONTAINS A "CATEGORY 2" LEVEL OF RADIOACTIVE MATERIAL

Category 2 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for a short time (minutes to hours). It could possibly be fatal to be close to this amount of unshielded radioactive material for a period of hours to days. These sources are typically used in practices such as industrial gamma radiography, high dose rate brachytherapy and medium dose rate brachytherapy.

PART 21 REPORT - MPR EMERGENCY DIESEL ENGINE TIMING MODULE FAILURE

The following is excerpted from a report submitted by MPR Associates, INC.:

"The basic component that contains a defect is an MPR Model 0380-1103 Timing Module. Six modules are in use for the three Emergency Diesel Generators (EDGs) at Plant Hatch Unit 2. Eight modules are at Plant Hatch as spares. The modules use a field programmable gate array (FPGA) to implement a specific pre-programmed load shedding and load sequencing logic associated with the standby power source safety function of the Hatch Unit 2 EDGs.

"MPR Timing Module Part Number 0380-1103, Serial Number 16 failed after operating successfully, along with five other installed modules, for more than eight months. The module failure resulted from a capacitor short in the input power circuit. When the capacitor shorted, the module ceased to function and annunciated its failure in the Main Control Room. The other five installed modules have given no indication of failure to date.

"MPR identified a replacement capacitor model that is suitable for the application and the application is within the manufacturer's recommendations. MPR is working with Plant Hatch to develop a schedule for rework to restore the expected design life of the timing modules."

PART 21 REPORT - ERROR IN REPORTING THE VARIABILITY IN THE DOSE DELIVERED ON CERTIFICATE OF PROCESSING

The following information was received from Homewood Products Corporation via fax:

"Steris Isomedix Services measuring and test equipment used by NTS (Formerly Wyle Laboratories, Inc.) to determine the applied radiation dose did not account for all of the uncertainties involved, and therefore the actual radiation dose applied to components and reported to Homewood Products Corporation by Wyle Laboratories, could be less than the requested service condition dose."

The following information was received from Homewood Products Corporation as provided to them by National Technical Services, Inc. (formerly Wyle Laboratories, Inc.):

"The defect is an error in reporting the variability in the dose delivered or lack thereof on the lsomedix Certificate of Processing for the Whippany, NJ facility. The U.S. Nuclear Regulatory Commission (NRC) under 10 CFR Part 50, Appendix B issued a Notice of Nonconformance 99901145/2014-201-01 to Steris stating that the measuring and testing equipment used to determine the applied radiation dose reported on the lsomedix Certificate of Processing provided with each gamma irradiation run did not account for all the uncertainties involved (i.e. density of unrelated products in carriers, off-carrier locations within the irradiator, and Cobalt-60 source decay) and therefore the actual radiation dose applied to components could be less than requested as reported on the Certificate of Processing.

"Steris lsomedix Services completed an evaluation of the dose rate variability of items processed in off-carrier locations in the irradiator. Steris Isomedix Services Position Paper dated 4/27/15 states the overall variability (uncertainty) associated with gamma radiation exposures at their Whippany, NJ facility."

The affected facilities have been notified of the non-conformance. They are:

Homewood Products Corporation, Pittsburgh, PA
Homewood Energy Services, Pittsburgh, PA
