REPORT DETAILS
Summary of Plant Status
Oyster Creek began the quarter at 100% power. On July 23, 2012, an unplanned scram occurred due to a loss of all offsite power. Operators commenced startup on July 26, 2012 and returned to full power on July 28, 2012.
On July 29, 2012, operators lowered power to 70% to perform a rod for flow swap. During the subsequent power ascension, C feed water regulating valve failed at 83% power and operators performed an unplanned power reduction to 67% power to conduct repairs. Oyster Creek returned to full power on July 31, 2012, following repairs to the C feed water regulating valve.
On July 31, 2012, operators lowered power to 70% to perform a rod pattern adjustment and returned the plant to full power on August 1, 2012.
On August 3, 4, 5, 6, and 12, 2012, Oyster Creek performed downpowers to comply with the New Jersey Department of Environmental thermal discharge permit.
On August 8, 2012, operators conducted an unplanned downpower to 90% in response to a trip of the reactor water cleanup system. Oyster Creek returned to full power on August 10, 2012.
On August 16, 2012, operators conducted a planned downpower to 98% to place the reactor water cleanup system back in service and returned to full power later that day.
On September 1, 2012, operators lowered power to 80% to perform a rod for flow swap and returned the plant to full power later that day.
On September 5, 2012, operators conducted a planned downpower to 95% to perform core spray system 1 surveillance testing. Oyster Creek returned to full power on September 7, 2012.
On September 11, 2012, operators conducted a planned downpower to 92% to perform core spray system 2 surveillance testing. Oyster Creek returned to full power on September 12, 2012.
On September 15, 2012, operators lowered power to 70% to perform a rod for flow swap and returned the plant to full power later that day.
On September 28, 2012, operators conducted an unplanned downpower to 70% in response to a salt water leak on the A-north circulating water discharge piping. Following repairs, Oyster Creek returned to full power on September 29, 2012.

2RS4 Occupational Dose Assessment
a. Inspection Scope
The inspectors reviewed the results of Exelon radiation protection program audits related to internal and external dosimetry. The inspectors reviewed the most recent National Voluntary Laboratory Accreditation Program accreditation report on the licensee vendors most recent results to determine the status of the accreditation. The inspectors reviewed licensee procedures associated with dosimetry operations, including issuance/use of external dosimetry, assessment of internal dose, and evaluation of and dose assessment for radiological incidents. The inspectors evaluated whether the licensee had established procedural requirements for determining when external dosimetry and internal dose assessments are required. The inspectors waked down and evaluated the onsite storage of dosimeters before issuance, during use, and before processing/reading. The inspectors also reviewed the guidance provided to radiation workers with respect to care and storage of dosimeters. The inspectors reviewed dosimetry occurrence reports or corrective action program documents for adverse trends related to electronic pocket dosimeters. The inspectors reviewed procedures used to assess the dose from internally deposited radionuclides using whole body counting equipment. The inspectors reviewed the documentation for two individuals who had declared pregnancy during the current assessment period and evaluated whether the licensees radiological monitoring program (internal and external) for declared pregnant workers is technically adequate to assess the dose to the embryo/fetus. The inspectors reviewed exposure results and monitoring controls the licensee implemented. The inspectors evaluated the licensees neutron dosimetry program, including dosimeter types and/or radiation survey instrumentation.
b. Findings

2RS5 Radiation Monitoring Instrumentation
a. Inspection Scope
The inspectors reviewed maintenance records, testing records, source check records, calibration records, alarm setpoint calculations and walked down a sample of various radiation monitors including whole-body counters used to detect workers surface and internal contamination to verify proper setup and operation. The inspectors reviewed Exelon and third-party evaluation reports of the radiation monitoring program since the last inspection to look for trends. The inspectors reviewed procedures that govern instrument source checks and calibrations, focusing on instruments used for monitoring transient high radiological conditions, including instruments used for underwater surveys.
The inspectors walked down a representative sample of Exelons effluent radiation monitoring systems and observed Exelon personnel conducting source checks to verify proper operation of the monitors. The inspectors walked down area radiation monitors and continuous air monitors to determine whether they are appropriately positioned relative to the radiation sources or areas they were intended to monitor.
The inspectors reviewed daily performance checks and calibration data to show that the frequency of the calibrations is adequate and there were no indications of degraded performance of laboratory analytical instruments used for radiological analyses.
b. Findings
