| Event Text AN ISOLATION VALVE DID NOT CLOSE DURING A MAINTENANCE EVOLUTION
"On 8/20/2014, 0820 hrs [EDT], the Plant Shift Superintendent was notified of the following condition:
"During a maintenance evolution to change the machine drive unit (MDU) software, one of the four primary isolation valves comprising the machine isolation valve (MIV) set did not close as required. Specifically, the purge vacuum (PV) isolation valve did not close. All other isolation valves did close as required.
"This event is being reported as a loss or degradation of an IROFS [Item Relied on for Safety] that results in a failure to meet the performance requirements of Section 70.61 [and is reportable per 70.50(b)(2)]."
The licensee will notify the NRC Resident Inspector.

"On 09/08/2014, the Plant Shift Superintendent, with concurrence of USEC-ACP RO [Regulatory Oversight] determined that this event can be retracted.
"Engineering Evaluation, EE-2101-0053 Rev. 0, establishes the basis for retracting Event Number 50384. The retraction is based upon an analysis showing that failure of the purge vacuum (PV) isolation valve in the machine isolation valve (MIV) IROFS does not create a condition that results in a failure to meet the performance requirements of 10 CFR 70.61."
The licensee will notify the NRC Resident Inspector.

The following information was received via facsimile:
"On August 29, 2014, the licensee made a telephone notification of a medical event which occurred during a skin treatment using a Nucletron microSelecton 106.990 HDR. The Radiation Safety Officer indicated that a decay corrected value for the source activity was used during data entry for the treatment plan. The licensee discovered, after the administration of the treatment fraction, that the software also corrected for decay in determining the exposure time for the fraction. The extra decay correction resulted in a dose approximately twice the prescribed fraction dose of 600 cGy. The licensee has informed the referring physician and held a staff meeting to discuss the circumstances. Any future treatment fractions for the patient will be reviewed and the licensee will review its nine previous skin treatment procedures to determine if additional medical events may have occurred. Additional information, including the administered dose, will be provided by the licensee in its written report."

The following information was received via facsimile:
"At approximately 0950 MST on August 28, 2014, the Agency [Arizona Radiation Regulatory Agency] was informed that the licensee had a Troxler Model 3430, portable moisture/density gauge damaged at a construction site. The damage occurred at approximately 0930 MST on August 28, 2014. The gauge was in use and was run over by construction equipment. The sealed sources were not damaged and were intact. The damaged gauge was leak tested and will be returned to Troxler for repairs. The Troxler gauge, serial number 35809, contains 8 mCi of Cesium-137 and 40 mCi of Am:Be-241.
"The Agency continues to investigate the event. The Governor's Office and US NRC are being notified of this event."

PART 21 GROUP (EMAI)
| Event Text PART 21 - FAILURE TO MEET SPECIFIED IRRADIATION DURING TESTING OF COATED TEST PANELS
The following information is a synopsis of information received via facsimile:
Underwater Construction Corporation (UCC) was notified by Steris Isomedix Services (SIS) that test panels coated with Bio-Dur 560Blue epoxy coating, which SIS had been contracted to irradiate to a minimum accumulated dose of 1000 Mrad, could possibly have received a dose of only 949 Mrad due to a variance of 5.1 percent not previously reported on the Steris Component Irradiation Certificate. Bio-Dur 560Blue is a Service Level I coating. Failure to meet irradiation requirements for qualifying Service Level I coatings could result in the coating disbonding from the substrate, thus clogging Emergency Core Cooling Strainers during a postulated Loss of Cooling Accident (LOCA).
Bio-Dur 560Blue was used to reline the toruses at Peach Bottom Units 2 and 3. Also, 588 square feet of Bio-Dur 560Blue was applied to the liner of the suppression pool at Limerick Unit 1. UCC notified Exelon concerning the irradiation failure and provided the following recommendations:
- Perform evaluation of their Safety Analysis Report to determine if 949 Mrad meets licensing commitments.
- Perform a review and determine if Supplemental Test Report per Exelon Contract 00045628, Release 00735, whereby irradiation testing of Bio-Dur 560Blue was performed to 1000 Mrad by University of Massachusetts will provide reasonable assurance that coating will not fail during a LOCA.
