On May 14, 2012, via electronic mail, the NRC provided adraft request for additional information (RAI) related to radiation protection needed to supportthe AHPB technical review of the CR-3 Extended Power Uprate (EPU) License AmendmentRequest (LAR) following a teleconference on May 9, 2012 with FPC to confirm anunderstanding of the information provided in the CR-3 EPU LAR. On July 5, 2012, the NRCprovided a formal RAI required to complete its evaluation of the CR-3 EPU LAR. Thefollowing provides the CR-3 formal response to the RAI needed to support the AHPB technicalreview of the CR-3 EPU LAR. For tracking purposes, each item related to this RAI is uniquelyidentified as AHPB X-Y, with X indicating the RAI set and Y indicating the sequential itemnumber.AHPB RAIAHPB 3-1On page 2.10.1-2 of Attachment 5 to the original LAR dated June 15, 2011, the licensee statesthat the zone criteria established for the general accessible areas in the containment was < 25millirem per hour. It acknowledges that during the design of the plant, this was accomplished bydesigning the shields at an assumed power level of 2544 MWt to ensure dose rates at variouslocations were less than the specified zone criteria. The licensee evaluates the impact of the EPUby using actual operating data and providing the total person-rem for containment entries atpower as well as the maximum dose to any individual working at the plant. While it may be truethat the change in dose rates in accessible areas is not expected to increase significantly after theEPU and therefore, cumulative doses can be kept as low as reasonably achievable and individualdoses below Title 10 of the Code of Federal Regulations, Part 20 occupational dose limits, thedose information does not demonstrate that the original dose rates established in the originalshield design will not increase beyond their original design values. Provide justification thatdemonstrates that the dose rates are not expected to increase beyond the dose rates establishedunder the original shielding design analysis performed at an assumed power level of 2544 MWt.Response:The intent of the statement related to the zone criteria established for the general accessible areasin the containment on page 2.10.1-2 of the CR-3 EPU Technical Report (TR) (Reference 1,Attachments 5 and 7) was to acknowledge the historic basis for the plant shielding design asdescribed in Section 11.3, "Radiation Shielding," of the CR-3 Final Safety Analysis Report(FSAR). FSAR Section 11.3 provides a list of radiation occupancy zones; Zones 0 to IV. Asindicated in FSAR Section 11.3, the zones not designed as restricted access (i.e., > 100 mrem/hr)were originally intended to be < 25 mrem/hr. However, there are limited access areas within thereactor building (RB) (i.e., containment), outside the secondary shield, where radiation levelscurrently exceed the historical FSAR Section 11.3 value of 25 mrem/hr excluding considerationof the impact associated with operation at EPU conditions.
U.S. Nuclear Regulatory Commission Attachment3F0712-07 Page 2 of 3The current areas in Zone III that exceed 25 mrem/hr include: the area near a portion of theletdown line that bypasses the RB secondary shield; and the RB sump area. At existing fullpower conditions, the radiation levels in these areas at 30 cm may exceed 100 mrem/hr, but areless than 1000 mrem/hr. Therefore, access at power is restricted by maintaining the RB lockedexcept during periods when RB access is required. Access to both of these areas are controlledby the CR-3 Radiological Protection Program (RPP) in accordance with 10 CFR 20.1601(a) orCR-3 Improved Technical Specifications 5.8.1, "High Radiation Area." FPC has initiated anFSAR Change Request to revise the zone figures in Section 11.3 to identify these areas asrestricted access areas (i.e., Zone IV).The original CR-3 plant shielding design is considered conservative based upon a fission productsource term assumption of 1% failed fuel at full power operation conditions. This is consideredconservative for the following reasons:* 1% failed fuel is equivalent to a Dose Equivalent Iodine-131 (1-131) activity ofapproximately 4.5 [tCi/gm, which is 4.5 times the original operating Dose Equivalent 1-131activity limit of 1.0 ýtCi/gm; and* 1% failed fuel is 4 times greater than the fission product source criterion of 0.25% failed fuelfor plant shielding design provided in Regulatory Position 2.C of Regulatory Guide 8.8,"Information Relevant To Ensuring That Occupational Radiation Exposures At NuclearPower Stations Will Be As Low As Is Reasonably Achievable," (Reference 2).The Dose Equivalent 1-131 limit is being further reduced for EPU operation from 1.0 PCi/gm to0.25 ýXCi/gm resulting in limiting fission product sources to approximately 5.5% of that assumedfor the original plant shielding design.Thus, it is reasonable to conclude that, at EPU conditions, the existing plant shielding design cancontinue to limit radiation dose rates from fission product sources to within the rates establishedunder the original shielding design analysis. It is also reasonable to conclude, based on theconservative CR-3 plant shielding design and the Dose Equivalent 1-131 operational limitreduction from 1.0 ýtCi/gm to 0.25 pCi/gm, that operation at EPU conditions will not result inany accessible RB area radiation level exceeding 1000 mremi/hr; and therefore, will not result inany current accessible area in the CR-3 containment being restricted as a locked high radiationarea.Also, current radiation occupancy and routine personnel access is controlled by the CR-3 RPPand based on plant radiation surveys, which ensures compliance with 10 CFR 20 individual doserequirements and maintains cumulative dose as low as reasonably achievable irrespective of theradiation zones identified in FSAR Chapter 11.Finally, as indicated in Table 2.12.1-3, "Comparison of Proposed EPU Tests to FSAR Chapter13 Initial Startup Testing," of the CR-3 EPU TR, a biological shield survey will be conductedduring power ascension testing at various power levels, up to 100% of the EPU power level, toconfirm the adequacy of the plant radiation shielding.
