Implementation of these controls was reviewed against the criteria contained in 10 CFR 20, technical specifications, and NextEra's procedures.

Radiological Hazards Control and Work Coverage The inspector identified areas at Seabrook where radiologically significant work was being done. The inspector reviewed radiation survey maps and radiation work permits (RWP) associated with these areas to determine if the associated controls were acceptable. The inspector interviewed selected workers to determine if the workers were informed of the radiological conditions at the job site, electronic dosimeter alarm set points, and actions to be taken if a dosimeter alarms. Specific work activities observed included replacement of the non-metallic liner in the transfer canal and cask wash pit in the fuel storage building.

The inspector toured the accessible radiological controlled areas in the plant, including the primary auxiliary building, fuel handling building, decay heat vault, and waste processing building, and with the assistance of a radiation protection technician performed independent surveys of selected areas to confirm the accuracy of survey data and the adequacy of postings. During this tour, the inspector verified that selected locked high radiation areas (LHRA) were properly secured and posted.

In evaluating the radiation work permits (RWP), the inspector reviewed electronic dosimeter dose/dose rate alarm set points to determine if the set pOints were consistent with the survey indications and plant policy. The inspector verified that workers were knowledgeable of the actions to be taken when the dosimeter alarms, or malfunctions, for tasks being performed under selected RWPs.

.

Problem Identification and Resolution A review of Nuclear Oversight Daily Quality Summary reports. related condition reports, and an audit report (No.SBK-10-012) was conducted to determine if identified problems and negative performance trends were identified and entered into the corrective action program, and evaluated for resolution.

Relevant condition reports (CR). associated with radiation protection control access were reviewed and discussed with NextEra staff to determine if the follow up activities were being conducted in an effective and timely manner, commensurate with their safety significance. The inspector also reviewed the electronic dosimeter dose and dose rate alarm reports to determine that for every alarm a condition report was initiated and that the cause was appropriately established.

High Radiation Area and Very High Radiation Area Controls Procedures for controlling access to High Radiation Areas (HRA) and Very High Radiation Areas (VHRA} were reviewed to determine if the administrative and physical controls were adequate. The inspector also reviewed the physical and procedural controls for securing and removing highly contaminated/activated materials stored in the spent fuel pool and transfer canal. The inspector discussed with radiation protection management, the adequacy of current LHRANHRA controls, including prerequisite communications and authorizations, and verified that any changes made to relevant procedures did not substantially reduce the effectiveness and level of worker protection.

Implementation of these controls was reviewed against the criteria contained in 10 CFR 20, applicable industry standards, and NextEra's procedures.

Radiological Work Planning The inspector reviewed pertinent exposure information regarding the fall 2009, OR13 refueling outage, current exposure trends, and ongoing activities to assess ALARA performance. A review of 2009 outage dose was conducted to compare actual exposures with forecasted estimates to determine if differences were properly addressed in Work-In-Progress and Post-Job ALARA reviews.

The inspector evaluated the departmental interfaces between radiation protection, operations, maintenance crafts, and engineering to identify misSing ALARA program elements and interface problems. The evaluation was accomplished by attending an ALARA briefing for replacement of the non-metallic liner in the transfer canal, reviewing Station Radiation Safety Committee meeting minutes, and a Nuclear Oversight audit:

and interviewing the acting Radiation Protection Manager.

Verification of Dose Estimates The inspector reviewed the assumptions and basis for the annual (2010) site collective dose, exposure projections and actual exposure data for routine power operations. The inspector reviewed the effectiveness of initial job planning measures and NextEra's efforts in monitoring and controlling dose, during job completion.

The inspector reviewed Next Era's procedures associated with monitoring and re evaluating dose estimates when the forecasted cumulative exposure for tasks differed from the actual exposure received. The inspector reviewed the dose/dose rate alarm reports, and exposure data for selected individuals receiving the highest Total Effective Dose Equivalent (TEDE) for 2009 and for 2010, to confirm that no individual exposure exceeded the regulatory limit, or met the performance indicator reporting guideline.

Jobs-In-Progress The inspector observed a job-in-progress to evaluate the effectiveness of dose and contamination control measures. The job observed was replacement of the non-metallic liner in the transfer canal. As part of this evaluation, the inspector attended the pre-job ALARA briefing, reviewed the RWP and associated survey maps, evaluated contamination control measures, and observed the job in progress.

Problem Identification and Resolution The inspector reviewed elements of Next Era's corrective action program related to implementing ALARA program controls, including condition reports, Nuclear Oversight daily quality summary reports, an audit, and dose/dose rate alarm reports, to determine if problems were being entered at a conservative threshold and resolved in a timely manner.

.2 Annual Sample: Actions to Address Service Water System Issues Inspection Scope

a. Inspection Scope

This inspection was conducted to assess whether NextEra's corrective actions associated with issues concerning the service water (SW) system were reasonable to correct the identified causes and prevent recurrence of the problems. Specifically, the inspectors reviewed actions taken to address a non-cited violation (NCV 05000443/2009004-01) regarding the failure to verify that boundary valve leakage was within design assumptions (CR 201099). The inspectors also reviewed the actions taken regarding corrosion of the bolting on the "A" diesel generator (DG) jacket water heat exchanger drain valve, 1-SW-V-515 (CR 197963).

The inspectors reviewed calculations, work orders, condition reports (CRs) and an apparent cause evaluation to assess the effectiveness of NextEra's corrective actions.

The inspectors discussed with station personnel the short and long term corrective action plans and the extent-ot-condition reviews. Additionally. the inspectors conducted a walkdown of accessible portions ot the SW system to evaluate the material condition of the system. Documents reviewed are listed in the Attachment.

b. Findings and Observations

No findings were identified.

The inspectors determined that NextEra's actions associated with the two service water issues were reasonable to correct the identified causes and repair the degraded conditions. For the CRs reviewed, the associated evaluations were appropriately detailed to identify apparent causes and to develop suitable corrective actions. During the course of the review, the inspectors noted that the SW system had some material degradation challenges (e.g., surface corrosion), most of which appeared to be attributed to environmental conditions of the system {e.g., humidity}. NextEra had submitted CRs for the noted deficiencies, and was developing actions to improve the material condition.

40A3 Event Follow Up (71153 -1 sample)

.1 . (Closed) LER 05000443/2010-002, Containment Penetration Protection Devices

Licensee Event Report 2010-02 dated 6/8/2010 reported NextEra's determination per 10CFR50.73(a)(2)(i)(B) that the plant had operated in a condition prohibited by Technical Specifications (TSs). Surveillance testing in April 2010 identified that the instantaneous trip set points for containment penetration over current protection devices were not set correctly. Both the primary and secondary device trip set points for the train-B hydrogen re-combiner were set at 1094 amps versus the design value of 781 amps. Past plant operations with the incorrect trip settings was contrary to the requirements of TS 3.8.4.2. The correct set points were re-established after they were identified. An engineering evaluation (CR220912) determined that, even with the incorrect settings, the protection devices would have protected the containment penetration. Thus, the containment protection circuit remained functional with large margins to the equipment limits. .

The condition was discovered by NextEra during a planned surveillance activity whose purpose was to verify trip setting met TS requirements. The NextEra investigations of the issue (apparent cause for CR220912) identified that the issue was caused by previous performance deficiencies. The incorrect set pOints were established when the devices were installed in 2002 (90MMOD663); further, there were missed opportunities to identify the error in 2004 due to an inadequate procedure, and in 2008 due to the failure to follow procedures. The A-train hydrogen recombiner protection devices were verified to be set correctly. An extent of condition review determined there were no other protection devices with incorrect trip setpoints.

The inspectors reviewed the accuracy of the LERand verified compliance with the reportability reqUirements in 10 CFR 50.73. The LER concerned a condition that was a minor violation of NRC requirements established in TS 3.8.4.2, and caused by the failure to meet requirements stated in Technical Specification 6.7.1 related to procedures and procedure use. The failure to comply with the aforementioned TS requirements constitutes violations of minor Significance that are not subject to enforcement action in accordance with the NRC Enforcement Policy. This LER is closed.
