: (1) Quality Assurance Audits and Surveillances  
: (1) Quality Assurance Audits and Surveillances An on-site review of Quality Assurance (QA) audits and surveillance reports related to dry cask storage activities at the River Bend Station ISFSI was performed by NRC inspectors. Since the last NRC inspection in September 2012, RBS had not issued a completed ISFSI QA audit report. The last ISFSI QA audit was performed in August 2012 and was reviewed in the last ISFSI inspection report. At the time of this routine ISFSI inspection RBS had completed the 2014 ISFSI QA audit but the report had not been issued yet. Two licensee surveillances documented in Oversight Observation Checklist (O2C) reports were reviewed during this inspection. The OC2 reports documented QA observations made in ISFSI areas of radiation protection and maintenance. The surveillances did not result in any QA findings.
 
: (2) Radiological Conditions Related to Stored Casks The RBS ISFSI was located approximately 500 feet south of the reactor building within the plant protected area (PA). The pad was roughly 60 feet wide and 209 feet long designed to hold 40 HI-STORM 100S spent fuel storage casks configured in a 4 by 10 array. The pad was also designed to contain four extra cask spaces which were intended to facilitate cask movement operations. The RBS ISFSI was protected on all sides by an exclusion area fence, which was properly posted as a Radioactive Materials Area. No flammable or combustible materials, debris, or notable vegetative growth were observed inside the ISFSI area. Twenty-one casks were loaded with spent fuel at the time of the inspection. The current ISFSI loading campaign was scheduled to add an additional two casks to the pad, bringing the total number to 23 by the end of September 2014. The inspectors found the 21 HI-STORM casks to be in good physical condition.

Radiological conditions at the RBS ISFSI were determined from the most recent semi-annual radiological survey and records from three years of optically stimulated luminescence dosimeter (OSLD) monitoring results. There were eight OSLD monitoring locations that were positioned along the four sides of the ISFSI exclusion area fence, two OSLDs per side.

A RBS radiation protection (RP) techni cian accompanied the NRC inspectors during the walk-down of the ISFSI pad area. A radiological survey was performed by the RP technician with an ion-chamber to record gamma exposure rates in milli-roentgens per hour (mR 1/h). The RP technician also carried a survey meter that measured neutron exposure in units of dose equivalent, millirem per hour (mrem/h). The NRC inspector carried a Ludlum Model 19 scintillation detector that was capable of measuring low level gamma radiation exposure rates in micro-roentgens per hour (µR/h). Survey measurements were taken at ISFSI area fence locations, around the perimeter of the ISFSI pad, at selected areas between casks, and at HI-STORM lower vent locations.
A RBS radiation protection (RP) technician accompanied the NRC inspectors during the walk-down of the ISFSI pad area. A radiological survey was performed by the RP technician with an ion-chamber to record gamma exposure rates in milli-roentgens per hour (mR1/h). The RP technician also carried a survey meter that measured neutron exposure in units of dose equivalent, millirem per hour (mrem/h).


General area gamma background readings outside the power plant prior to entry into the ISFSI pad area were 6 µR/h. The 21 storage casks were situated along the eastern edge and northeastern corner of the ISFSI pad. Radiation readings taken along the fence-line showed radiation levels ranging from 20 to 44 µR/h. General area measurements on the pad ranged from 60 to 300 µR/h. Several cask lower vent measurements were taken. The vent measurements ranged from 0.3 to 1.1 mR/h gamma and 0.5 to 1.0 mrem/h neutron. The measurements recorded by the NRC inspector and RP technician confirmed the most recent semi-annual ISFSI survey.

: (3) Environmental Radiological Monitoring Program The primary purpose of the RBS Radiological Environmental Monitoring Program (REMP) was to evaluate the radiological impacts that reactor operations and stored radioactive materials may have on the local environment. The REMP was focused on measuring airborne (gaseous and particulate), liquid effluent, and direct radiation levels onsite, at the site boundary, and at offsite locations. By design, there were no airborne or liquid effluents released from the RBS ISFSI. NRC reviewed the


Spent Fuel Storage Radioactive Effluent Release Reports for 2012 (ML13064A382)and 2013 (ML14064A206) for RBS, which confirmed that the RBS ISFSI did not produce any effluent radioactive releases during 2012 or 2013.

: (4) Records Related to Fuel Stored in the Casks


A site review of dry fuel storage records for eight randomly selected loaded casks at the RBS ISFSI was performed to determine whether adequate descriptions of the spent fuel was documented as a permanent record as required by 10 CFR 72.212(b)(12). In addition, the fuel contents of the first two casks loaded during the current four cask loading campaign were verified against Holtec CoC 1014 Technical Specification (TS) requirements for BWR fuel assemblies loaded into an MPC-68 canister. The spent fuel contents of the eight randomly selected casks were recorded in documents that included procedure REP-0061, "Fuel Selection for Dry Storage," dated November 18, 2005 and October 22, 2008; and EN-DC-215, "Fuel Selection for Holtec Dry Cask Storage," Revs. 3 and 5.

PLANT AND ISFSI STATUS River Bend Station (RBS) Independent Spent Fuel Storage Installation (ISFSI) stored nineteen loaded Holtec HI-STORM 100S Version B casks and two HI-STORM 100S casks at the time of the routine inspection. RBS was loading the third canister in their four cask loading campaign.

Inspectors observed loading operations associated with cask number 22 at the time of the routine inspection. The licensee utilized a general Part 72 license in accordance with the Holtec HI-STORM 100 System, approved under Certificate of Compliance 1014, License Amendment 5 and Final Safety Analysis Report (FSAR), Revision 7. The version of the Holtec systems used by the licensee included the MPC-68, a 68 fuel bundle multi-purpose canister (MPC), designed to hold 68 boiling water reactor (BWR) fuel assemblies. The ISFSI consisted of one concrete pad that could accommodate 40 casks. The storage casks were located inside the Part 50 facilitys protected area (PA).

The reactor at RBS is a BWR with a core containing 624 fuel assemblies. Refueling outages are performed approximately every 24 months. The spent fuel pool capacity at RBS is 3,104 spaces. After the current loading campaign is complete, spent fuel pool will contain 946 spaces that are open and available for use. The licensee has maintained the ability to perform a full core off-load.

a. Inspection Scope

(1) Quality Assurance Audits and Surveillances An on-site review of Quality Assurance (QA) audits and surveillance reports related to dry cask storage activities at the River Bend Station ISFSI was performed by NRC inspectors. Since the last NRC inspection in September 2012, RBS had not issued a completed ISFSI QA audit report. The last ISFSI QA audit was performed in August 2012 and was reviewed in the last ISFSI inspection report. At the time of this routine ISFSI inspection RBS had completed the 2014 ISFSI QA audit but the report had not been issued yet. Two licensee surveillances documented in Oversight Observation Checklist (O2C) reports were reviewed during this inspection. The OC2 reports documented QA observations made in ISFSI areas of radiation protection and maintenance. The surveillances did not result in any QA findings.
(2) Radiological Conditions Related to Stored Casks The RBS ISFSI was located approximately 500 feet south of the reactor building within the plant protected area (PA). The pad was roughly 60 feet wide and 209 feet long designed to hold 40 HI-STORM 100S spent fuel storage casks configured in a 4 by 10 array. The pad was also designed to contain four extra cask spaces which were intended to facilitate cask movement operations. The RBS ISFSI was protected on all sides by an exclusion area fence, which was properly posted as a Radioactive Materials Area. No flammable or combustible materials, debris, or notable vegetative growth were observed inside the ISFSI area. Twenty-one casks were loaded with spent fuel at the time of the inspection. The current ISFSI loading campaign was scheduled to add an additional two casks to the pad, bringing the total number to 23 by the end of September 2014. The inspectors found the 21 HI-STORM casks to be in good physical condition.

Radiological conditions at the RBS ISFSI were determined from the most recent semi-annual radiological survey and records from three years of optically stimulated luminescence dosimeter (OSLD) monitoring results. There were eight OSLD monitoring locations that were positioned along the four sides of the ISFSI exclusion area fence, two OSLDs per side.

A RBS radiation protection (RP) technician accompanied the NRC inspectors during the walk-down of the ISFSI pad area. A radiological survey was performed by the RP technician with an ion-chamber to record gamma exposure rates in milli-roentgens per hour (mR1/h). The RP technician also carried a survey meter that measured neutron exposure in units of dose equivalent, millirem per hour (mrem/h).

The NRC inspector carried a Ludlum Model 19 scintillation detector that was capable of measuring low level gamma radiation exposure rates in micro-roentgens per hour (µR/h). Survey measurements were taken at ISFSI area fence locations, around the perimeter of the ISFSI pad, at selected areas between casks, and at HI-STORM lower vent locations.

General area gamma background readings outside the power plant prior to entry into the ISFSI pad area were 6 µR/h. The 21 storage casks were situated along the eastern edge and northeastern corner of the ISFSI pad. Radiation readings taken along the fence-line showed radiation levels ranging from 20 to 44 µR/h. General area measurements on the pad ranged from 60 to 300 µR/h. Several cask lower vent measurements were taken. The vent measurements ranged from 0.3 to 1.1 mR/h gamma and 0.5 to 1.0 mrem/h neutron. The measurements recorded by the NRC inspector and RP technician confirmed the most recent semi-annual ISFSI survey. The radiological conditions of the ISFSI were as expected for the age and heat-load of the 21 (at the time of inspection) loaded spent fuel storage casks. The licensee was properly posting and controlling the ISFSI pad area consistent with 10 CFR Part 20 requirements.

The licensee provided personnel dose estimates associated with the first two casks loaded during the current ISFSI loading campaign, which began in late July 2014.

The estimated worker doses ranged from 0.334 to 0.194 person-rem per cask. The dose estimates were consistent with worker doses seen in previous loading campaigns at RBS. Personnel radiation doses were estimated using electronic For the purposes of making comparisons between NRC regulations based on dose-equivalent and measurements made in Roentgens, it may be assumed that one Roentgen equals one rem. (http://www.nrc.gov/about-nrc/radiation/protects-you/hppos/qa96.html)personnel dosimeters (EPDs) that were sensitive to both gamma and neutron radiation.

(3) Environmental Radiological Monitoring Program The primary purpose of the RBS Radiological Environmental Monitoring Program (REMP) was to evaluate the radiological impacts that reactor operations and stored radioactive materials may have on the local environment. The REMP was focused on measuring airborne (gaseous and particulate), liquid effluent, and direct radiation levels onsite, at the site boundary, and at offsite locations. By design, there were no airborne or liquid effluents released from the RBS ISFSI. NRC reviewed the Spent Fuel Storage Radioactive Effluent Release Reports for 2012 (ML13064A382)and 2013 (ML14064A206) for RBS, which confirmed that the RBS ISFSI did not produce any effluent radioactive releases during 2012 or 2013.

The REMP monitors direct radiation impacts using thermoluminescent dosimeter (TLD) monitoring. The ISFSI was monitored for direct radiation using OSLDs.

TLDs and OSLDs report in the same units and are considered to be functionally equivalent. The OSLD data for the ISFSI and the TLD data for the REMP were handled by different programs at RBS for different purposes. The ISFSI OSLD monitoring was performed by the RP department to track radiological exposures at the ISFSI boundary to ensure that NRC occupational limits for unmonitored individuals were not exceeded. The REMP monitoring was performed to provide an annual assessment of the licensees total impacts to the environment, which includes contributions from the ISFSI.

OSLDs were placed at eight monitoring locations on the fence around the ISFSI.

The OSLD monitoring results from 2012, 2013, and 2014 were reviewed by NRC inspectors (see Table 1, below). The OSLDs were collected and replaced twice a year.

Table 1 OSLD Monitoring Results for River Bend ISFSI in mR/yr OSLD # Location 2012 2013 20142 Z58 ISFSI North Fence 1 79 99 58 Z60 ISFSI North Fence 2 115 116 108 Z61 ISFSI South Fence 1 36 47 26 Z62 ISFSI South Fence 2 31 38 28 Z63 ISFSI East Fence 1 46 72 48 Z64 ISFSI East Fence 2 83 76 66 Z65 ISFSI West Fence 1 87 98 90 Z66 ISFSI West Fence 2 48 57 52 NRC Inspectors verified the radiation exposure rates at each OSLD monitoring location during the ISFSI walk-down. The highest reported dose rate, 116 mrem per year, was measured at the ISFSI North Fence 2 monitoring location. All accessible areas near the RBS ISFSI boundary were below the 10 CFR 20.1502(a)(1) limit, of 500 mrem per year for unmonitored workers.

The annual radiological exposure data for 2014 was estimated from actual monitoring data for the first half of the year.

The yearly results of the REMP were issued in an Annual Radiological Environmental Operating Report (AREOR). NRC reviewed the RBS AREORs for 2012 (ML12157A078), issued May 1, 2013 and 2013 (ML14126A007), issued May 1, 2014. The AREORs did not include the OSLD direct radiation monitoring results for the ISFSI, but provided reporting and analyses for the REMP TLD monitoring results.

The RBS ISFSI was located approximately 0.1 miles from the reactor building in the in the southern (S) REMP monitoring sector. Two of the 24 total REMP TLD monitoring sites were at site boundary locations in reasonably close proximity to the RBS ISFSI: TJ1, 0.9 miles from the reactor in the southern (S) sector and TK1, 0.6 miles from the reactor, in the south-southwest (SSW) sector. TEC was a control monitoring station located 9.9 miles east of the RBS reactor building. This TLD can be treated as a radiological background.

Table 2, TLD Monitoring Results near RBS ISFSI in mR/yr TLD# Station and Location 2012 2013 TJ1 S Sector, 0.9 miles from reactor 53.2 54.7 TK1 SSW Sector, 0.6 miles from reactor 55.0 58.5 TEC (Control) E Sector, 9.9 miles from reactor 57.8 57.9 Both REMP TLD monitoring results in close proximity to the RBS ISFSI were close to background (control levels). The most elevated readings were from the TK1 monitoring location for the years reviewed. That monitoring location was slightly below background in 2012 and slightly above background for 2013. Correcting the 2013 value for background yielded a net annual exposure rate of 0.6 mR1. This was well below the 10 CRF 72.104(a)(2) requirement of less than 25 mrem annual dose equivalent to any real individual located beyond the site controlled area. The radiological influence of the ISFSI on site boundary locations was minimal.

(4) Records Related to Fuel Stored in the Casks A site review of dry fuel storage records for eight randomly selected loaded casks at the RBS ISFSI was performed to determine whether adequate descriptions of the spent fuel was documented as a permanent record as required by 10 CFR 72.212(b)(12). In addition, the fuel contents of the first two casks loaded during the current four cask loading campaign were verified against Holtec CoC 1014 Technical Specification (TS) requirements for BWR fuel assemblies loaded into an MPC-68 canister. The spent fuel contents of the eight randomly selected casks were recorded in documents that included procedure REP-0061, Fuel Selection for Dry Storage, dated November 18, 2005 and October 22, 2008; and EN-DC-215, Fuel Selection for Holtec Dry Cask Storage, Revs. 3 and 5. These procedures included multi-purpose canister (MPC) loading maps and fuel assembly qualification data, including fuel assembly identifiers, decay heat (kW), cooling time (years),initial assembly average U-235 enrichment (%), burn-up values (MWd/MTU), and other fuel assembly characterization information. A complete set of forms were reviewed for the first two casks loaded of the current campaign and eight of the previously loaded MPCs. Select fuel data is tracked by cask on Attachment 2 of this inspection report. RBS was in compliance with all applicable license and FSAR requirements for fuel stored at the ISFSI and met retrievability requirements for storage of spent fuel records.
(5) Technical Specification 3.1.2, Cask Temperature Monitoring Technical Specification (TS) 3.1.2 included a surveillance requirement for either a daily inspection of the inlet and outlet vents for blockage or daily verification that the temperature difference between the HI-STORM outlet temperature and ISFSI ambient temperature was 126 degrees F for all casks loaded under Certificate of Compliance (CoC) Amendment 2 (casks 1-7) and 137 degrees F for casks loaded under CoC Amendment 5 (casks 8-21). None of the 21 total HI-STORM casks placed on the RBS ISFSI at the time of the inspection were equipped with remote temperature monitoring equipment. The vent inspection surveillances were performed using Surveillance Test Procedure STP-000-0001, Daily Operating Logs, Revisions 72, 74, and 76. Documentation was reviewed for three randomly selected weeks, the weeks of December 16, 2012, March 17, 2013, and November 24, 2013, for compliance with the TS surveillance. Of the three weeks selected for review, the surveillance requirement was met by performing daily vent inspections and logging the results into the aforementioned operating log. No cask inlet or outlet vents were reported as being blocked.
(6) Corrective Action Program A list of Condition Reports (CRs) issued since the last NRC inspection in September of 2012 was provided by the licensee for the cask handling crane and the ISFSI.

Issues were processed in accordance with Procedure EN-LI-102, Corrective Action Process, Revision 23. When a problem was identified the licensee documented the issue as a CR in the licensees corrective action program (CAP).

Of the list of CRs provided relating to the ISFSI and the cask handling crane, approximately 15 CRs were selected by the NRC inspectors for further review. The CRs related to a variety of issues. The CRs reviewed were well documented and properly categorized based on the safety significance of the issue. The corrective actions taken were appropriate for the situations. Based on the level of detail of the corrective action reports, the licensee demonstrated a high attention to detail in regard to the maintenance and operation of their ISFSI program and the cask handling crane. No NRC concerns were identified related to the CRs reviewed.

(7) Preparation of Loading Activities The inspectors requested documentation related to maintenance of the fuel building cask handling crane, the annual maintenance of the licensees special lifting devices, and the calibration of various gauges associated with the loading activities.

Documents were reviewed that demonstrated that the cask handling crane was inspected on an annual basis in accordance with American Society of Mechanical Engineers (ASME) B30.2 prior to the 2014 loading campaign. RBS utilized Procedure PM MHF-CRN2, Crane Periodic Inspection Mechanical, dated April 24, 2012 and Work Order (WO) 52506664 to perform the annual maintenance in June of 2014.

The annual maintenance as required by American National Standards Institute (ANSI) N14.6 for special lifting devices was completed for the following special lifting devices: the lift yoke, HI-STORM brackets, and the HI-TRAC lifting trunnions.

Documentation reviewed included WO 52494786, WO 52472971, WO 00383578, WO 00382024, and WO 00382023 and associated non-destructive examination documentation associated with the testing. All equipment passed the magnetic particle, liquid penetrant, and dimensional testing.

Calibration documentation of the hydrostatic pressure gages were reviewed to ensure the equipment had been properly calibrated prior to the loading operations.

All calibration certificates reviewed demonstrated that the gages were properly calibrated prior to the loading campaign. Documentation of the calibration was recorded in WO 00388250.

(8) HI-STORM 100 Cask Yearly Maintenance Holtec Final Safety Analysis Report (FSAR), Section 9.2, Maintenance Program, specified the HI-STORM maintenance schedule in Table 9.2.1. Among other tasks, the schedule called for annual visual inspection of the storage casks external surfaces and identification markings for signs of damage or degradation. NRC inspectors reviewed the documentation related to the annual visual examination of the HI-STORM casks for 2012 and 2013. Those documents included the work orders and filled out copies of Procedure WM-105-00, Attachment 1, HI-STORM Annual Inspection Form, dated, November 10, 2010. Those visual examination checklists included 25 points of inspection that were verified as satisfactory, unsatisfactory, or not applicable (N/A). For the years reviewed, one instance of an unsatisfactory condition was identified: A bolt holding a vent air screen in place was broken and needed to be replaced during the 2013 inspection. A work order was initiated to replace the broken bolt. The NRC inspectors determined that the licensees yearly maintenance activities and records satisfied the requirements of FSAR Section 9.2.
(9) Cask Loading Observations Various loading activities were observed by the NRC inspectors during the course of the routine ISFSI inspection. RBS was in the process of loading canister #22 at the time of the inspection. The NRC inspectors observed the fuel movement activities to place spent fuel assemblies into canister #22. The licensees staff was experienced in moving the spent fuel assemblies and was proficient in locating the correct assembly, verifying the assembly, moving the assembly from the rack to the canister, and inserting the assembly into the assigned canister slot. The time from grappling the assembly, placing the assembly into the assigned canister slot, and returning to the next assigned spent fuel assembly was approximately nine to ten minutes.

Selected welding and non-destructive examination activities were observed during the loading associated with canister #22. An automatic welding process was used to weld the canister lid. The automated welding machine utilized one weld head to weld the lid to shell weld. The welders operated the equipment remotely in a low dose rate area. Hydrogen monitoring was performed during the welding of the root weld and subsequent passes. The licensee monitored for combustible gas every ten minutes utilizing an in-line monitor through the MPC vent port until the final weld pass had been completed. Additionally, the NRC inspectors observed the non-destructive dye penetrant exams conducted on the shell to lid welds. No weld indications were identified from the various non-destructive examinations.

Other activities that were observed by NRC inspectors during the loading of canister

  1. 22 included the lifting the HI-TRAC transfer cask and fully loaded MPC out of the spent fuel pool. The licensees cask handling crane was able to handle the heavy load without problems.
