The VENTILATION EXHAUST TREATMENT SYSTEM shall be used to reduce radioactive materials in gaseous waste prior to their discharge when the projected doses due to gaseous effluent releases, from each reactor unit, to areas at and beyond the SITE BOUNDARY when averaged over 31 days, would exceed 0.3 mrem to any organ of a MEMBER OF THE PUBLIC.

9 PVNGS ARERR 2014

1.3 Total Dose 1.3.1 PVNGS ODCM Requirement 5.1 The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to direct radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.

2.0 MAXIMUM PERMISSIBLE CONCENTRATIONS Air: Release Concentrations are limited to dose rate limits described in section 1.2.1 of this report.

3.0 AVERAGE ENERGY The average energy (E) of the radionuclide mixture in releases of fission and activation gases is not applicable to PVNGS.

4.0 MEASUREMENTS AND APPROXIMATIONS OF TOTAL RADIOACTIVITY IN GASEOUS EFFLUENTS For continuous releases, sampling is in accordance with PVNGS ODCM Table 3-1.

Particulate and iodine radionuclides are sampled continuously at the Plant Vent and Fuel Building exhaust points. The particulate filters and charcoal cartridges are exchanged for analysis at least four times per month. Noble gas and tritium are sampled at least once per 31 days. The hourly average Radiation Monitoring System (RMS) effluent monitor readings are used, when available, to account for increases and decreases in noble gas concentrations between noble gas grab samples. The tritium concentration is assumed constant between sampling periods.

For batch releases, sampling is also in accordance with PVNGS ODCM Table 3-1. For containment purges, the noble gas concentration may be adjusted to account for decreases or increases in concentration during the purge using RMS readings. The volume of air released during the purge is determined using the exhaust fan rated flow rate. For Waste Gas Decay Tank releases, the volume released is corrected to standard pressure.

Effective January 1, 2004, Containment Purge release permits are updated by removing the permit pre-release particulate and iodine activity. This eliminates double accounting for the Containment Purge particulate and iodine activity at the Plant Vent but allows the particulate and iodine activity to be included in the Containment Purge pre-release dose projection.

The Lower Limit of Detection (LLD) of a measurement system is defined in Table 3 - 1 of the PVNGS ODCM. An average LLD for each radionuclide is provided in Table 3.

5.0 BATCH RELEASES 5.1 Gaseous.

Batch release durations are presented in Table 2.

5.2 Liquid None.

6.0 ABNORMAL RELEASES None.

7.0 OFFSITE DOSE CALCULATION MANUAL AND PROCESS CONTROL PROGRAM (PCP) REVISIONS 7.1 There were no revisions to the Offsite Dose Calculation Manual (ODCM) in 2014.

7.1 There were revisions to the Process Control Program (PCP) in 2014. The change package is attached as Appendix E.

8.0 EFFLUENTS AND SOLID WASTES 8.1 Gaseous Effluents Gaseous effluent information is presented in Table 1 through Table 41. Included in these tables are summaries of the effluents and estimated total error.

8.2 Liquid Effluents There were no liquid effluent releases beyond the Site Boundary from PVNGS.

8.3 Solid Waste Solid waste shipments are summarized in Table 42.

11 PVNGS ARERR 2014

9.0 MISCELLANEOUS INFORMATION 9.1 EVAPORATION PONDS Releases made to the Evaporation Ponds are limited to the concentrations specified in PVNGS ODCM Requirement 3.2. The Evaporation Ponds were monitored in accordance with PVNGS ODCM Requirement 6.1.

The average historical evaporation is approximately 12 inches, per pond, for each of the first and fourth quarters, and 33 inches, per pond, for each of the second and third quarters. Evaporation Pond One is approximately 250 acres. This equates to 3.08E+1 1 cc evaporated from Pond One for each of the first and fourth quarters and 8.48E+1 1 cc evaporated from Pond One for each of the second and third quarters. Evaporation Pond Two is approximately 235 acres. The amount evaporated from Pond Two is 2.90E+1 1 cc for each of the first and fourth quarters and 7.97E+1 1 cc for each of the second and third quarters.

Evaporation Pond Three is constructed of two smaller ponds of 90 acres each (3A and 3B). The amount evaporated from each section of Pond Three is 1.11E+11 cc for each of the first and fourth quarters and 3.05E+1 1 cc for each of the second and third quarters.

Using a site boundary X/Q of 5.OE-05 sec/mi3 for the evaporation ponds and equation 4-3 from the ODCM, the dose from the evaporation ponds to a hypothetical individual at the site boundary, for all pathways, is summarized in Table 1.

9.2 RADIATION MONITORING SYSTEM SETPOINT VERIFICATION Current effluent monitor noble gas channel alert alarm setpoints are based on an assumed one per cent failed fuel source term. The current method used for the setpoint values are more reliable than basing the setpoints upon the constantly varying values of the actual noble gas source term presented in Table 38.

9.3 RCS RADIOIODINE (TRM T5.0.600)

There were no cases where primary coolant specific activity exceeded the Technical Specification 3.4.17 limits during the reporting period.

9.4 INDEPENDENT SPENT FUEL STORAGE INSTALLATION (ISFSI)

There are no radioactive effluents from the NAC-UMS System. Direct dose at the Site Boundary is reported in the Annual Radiological Environmental Operating Report.

12 PVNGS ARERR 2014

9.5 MAJOR CHANGES TO THE RADIOACTIVE WASTE SYSTEMS (liquid, gaseous, and solid).

None.

9.6 SAMPLES RESULTS FROM GROUNDWATER WELLS THAT ARE NOT DESCRIBED IN THE ODCM AS PART OF THE REMP (NEI 07-07, Industry Groundwater Protection Initiative, August 2007), are included in Appendix D. This initiative provides added assurance that ground water will not be adversely affected by PVNGS operations.

There were no NEI 07-07, reportable leaks or spills.

There were no positive sample results.

9.7 REPORT ADDENDUM None.

10.4 Carbon-14 Carbon-14 is formed naturally in the upper atmosphere and also is formed in operating nuclear reactors.

Carbon-14 is not a new power plant emission. Because the overall quantity of radioactive releases has steadily decreased due to improvements in power plant operations, carbon-14 may now qualify as a "principal radionuclide" under revised federal regulatory guidance. The levels of other releases have declined, so carbon-14 releases, expressed as a percentage of total releases, have the potential to achieve "principal radionuclide" status (anything greater than one percent of overall radioactivity in effluents) per updated federal regulatory guidance.

The radiation dose to the public from carbon-14 is much lower than regulatory limits and has been a very small contributor to the total radiation dose that Americans receive each year from natural and manmade sources.

Studies by the United Nations Scientific Committee on the Effects of Atomic Radiation, the National Research Council's BEIR VII study group and the National Council on Radiation Protection and Measurements all show that the risk associated with low-dose radiation from natural and man-made sources, including nuclear power plants, is negligible.

Radiation is measured in units called millirem. The average American is exposed to 620 millirem of radiation every year. Approximately 311 millirem of this comes from natural sources. The majority of the remaining dose (approximately 300 millirem) comes from medical procedures such as CAT scans.Less than one-tenth of a percent of all radiation exposure is from nuclear facilities.

Reference:

NCRP Report No. 160, Table 1.1.

Starting with the 2010 Annual Radioactive Effluent Release Report, PVNGS will include the estimated exposure from carbon-14 in the Appendix C, dose calculations. The PVNGS calculated production of carbon-14 is 18.5 Curies per cycle (500 days) or 13.5 curies per year. Based on published literature, twenty percent (20%) of the carbon-14 released is assumed to be in an inorganic form (CO 2 ). PVNGS will use an estimated value of 2.7 curies of carbon-14 released, per reactor, per year. The 2.7 curies will be divided equally between each quarter (0.68 curies per reactor, per quarter). Appendix C, dose calculations include this estimated carbon-14 dose. Appendix C also includes the dose excluding carbon-14 for comparision with historical reports.

10.5 Tritium PVNGS does not have a liquid release pathway. Removal of tritium is performed by operation of the Boric Acid Concentrator (BAC) in the release mode.

Comparison of PVNGS annual tritium curies released to other utilities should be made only after summing both liquid and gaseous tritium curies released.

15 PVNGS ARERR 2014

10.6 Dose Summary Dose for 2014 was primarily due to the release of tritium. Tritium production is estimated to be 1000 curies per Reactor Unit per year. In order to control plant tritium concentrations, tritium releases should match tritium production. For 2014, PVNGS released a total of 2310 curies of tritium (see Table 39).

Total dose due to releases from all three Units for 2014 were higher than 2013, primarily due to increased releases of tritium.

APPENDIX B METEOROLOGY 61 PVNGS ARERR 2014

JOINT FREQUENCY DISTRIBUTION TABLES The tables presented in this section are results obtained from processing the hourly meteorological data collected at the Palo Verde Nuclear Generating Station for the period of January -

December 2014. The joint frequency distribution (JFD) tables represent the frequency, in terms of the number of observations, that a particular wind speed, wind direction, and stability category occurred simultaneously. On a quarterly, semiannual and annual basis, the JFDs were produced for 35-foot wind speed and wind direction by atmospheric stability class corresponding to the seven Pasquill stability categories, and for wind speed and wind direction for all stability classes combined. Atmospheric stability was classified per Regulatory Guide 1.23, using the 200-foot to 35-foot temperature difference (delta T).

In accordance with NUREG-01 33, the batch releases for the year were considered as "long term,"

since the batch releases are sufficiently random in both time of day and duration. Consequently, the JFDs for the batch releases for all quarters are the same as for the continuous releases.

Discussion A summary of 2014 Joint Frequency Distribution (JFD) shows a somewhat typical, but variable year. Of the 8760 hours0.101 days <br />2.433 hours <br />0.0145 weeks <br />0.00333 months <br /> available, 373 hours0.00432 days <br />0.104 hours <br />6.167328e-4 weeks <br />1.419265e-4 months <br /> of data were lost due to a communication line failure for an effective 95.7% data recovery.

The average 35 foot mean wind speed was 6.4 mph. Distribution of directions was spread over the compass with a predominant direction (3 sectors of 22.5 degrees each) centered on southwest.

(32.0%) A secondary maximum of three sectors centered on the north contained 18.8% of the total. Southwesterly flow winds averaged higher speeds with the most frequent speed at 10 mph.

With the northerly directions, the highest frequency occurred at 4.0 mph.

Stability class summary:

Stability class E, F, G, (stable categories) 58.7%.

Stability class G, (extremely stable) 26.7%.

Stability class A, B, C, (unstable categories) 20.7%.

Stability class D, (neutral category) 20.6%.

Overall stable conditions (E,F,G) existed for the year.

APPENDIX C DOSE CALCULATIONS 84 PVNGS ARERR 2014

GASEOUS EFFLUENT DOSE CALCULATIONS Doses to the maximum individual and the surrounding population resulting from the release of radioactive material in gaseous effluents from the Palo Verde Nuclear Generating Station were cal-culated using the GASPAR computer program. The radionuclides considered in the dose calcula-tions were Tritium, Iodine-131, Iodine-132, Iodine-133, Iodine-135, all noble gases, and particulates having a half-life greater than eight days and for which dose factors are contained in NUREG-01 72. Locations selected for individual dose calculations included for each sector, the site boundary, and within five miles, if present, the nearest residence, the nearest garden, and the nearest milk animal. GASPAR implements the radiological dose models of Regulatory Guide 1.109 to determine the radiation exposure to man from four principal atmospheric exposure pathways:

plume, ground deposition, inhalation, and ingestion. Doses to the maximum individual and the population were calculated as a function of age group and pathway for significant body organs.

Table 43 presents the doses on a quarterly, semiannual and annual basis for the Energy Informa-tion Center. An occupancy factor of 1.0 (implying continuous occupancy over the entire year) was considered for the Energy Information Center and the exposure pathways considered to calculate its doses were plume, ground deposition, and inhalation.

Table 44 presents the population dose.

Table 45 summarizes the individual doses and compares the result to PVNGS ODCM Require-ment limits. The site boundary and residence locations for which data are presented represent the highest annual doses.

Based on results obtained by placing TLDs on the site boundary in each sector, the net dose for this reporting period, from direct-radiation, (plume and ground deposition) from all three units was indistinguishable from preoperational values of 8 - 14 PR/hr (17 - 30 mR/Std Qtr).

There were no liquid effluents associated with the operation of this facility.

85 PVNGS ARERR 2014

Dose Calculation Models The GASPAR computer code was used to evaluate the radiological consequences of the routine release of gaseous effluents. GASPAR implements the dose calculational methodologies of Regu-latory Guide 1.109, Revision 1.

Source terms for each quarter are combined with station-specific demographic data and each quarter's atmospheric diffusion estimates for gaseous dose calculations.

Atmospheric diffusion estimates are generated by the XOQDOQ computer code using onsite meteorological data as input. Additional input to GASPAR includes the following site-specificdata:

0 to 5 mile nearest residence, milk animal and garden in each of the 16 compass sectors, based on the 2014 Land Use Census.

0 to 10 mile population from the PVNGS Emergency Plan, Rev 47.

The 10 to 50 mile population distribution from the PVNGS UFSAR, Figure2.1-12.

The population distribution of metropolitan Phoenix greater than 50 miles from PVNGS, based on the 1980 federal census results, is conservatively included in the 40 to 50 mile sectors (NE=123; ENE=140,097; E=621,130; ESE=8,392).

Absolute humidity of 6.0 g/m 3 from the PVNGS UFSAR, Table 2.3-16.

The fraction of the year that vegetables are grown (0.667) from the PVNGS ER-OL, Section 2.1.3.4, Table 2.1-8.

The fraction of daily feed derived from pasture while on pasture (0.35) and length of grazing season for milk animals beyond 5 miles (0.75) from the PVNGS ER-OL, Section 2.1.3.4.3.

The fraction of daily feed derived from pasture while on pasture (0.05) and length of grazing season for meat animals (0.25) from the PVNGS ER-OL, Section 2.1.3.4.4.

There were three (3) sectors containing milk animal (goat or cow) locations within five (5) miles. For calculation purposes these milk animals are assumed to be fed 100% on pasture grass during the year.

Other values used for input to GASPAR are default values from Regulatory Guide 1.109, Rev. 1.

Justification for reuision 76DP-ORP03, Radwaste Process Control Program describes the Process Control Program (PCP) at Palo Verde Nuclear Generating Station (PVNGS) for processing radioactive wet waste.

The scope of the program includes the processing of radioactive wet waste using plant portable processing systems, and or vendor provided portable processing systems. The process control program provides the procedures and processes by which the processing and packaging of low-level radioactive wet waste is accomplished to provide reasonable assurance compliance with the low-level radioactive waste characteristics requirements of 10CFR 61.56 are met, specifically the absence of free liquid.

76DP-ORP03, Step 3.1.1 lists the procedures considered to be within the scope of the PCP. Procedure 76RP-0RW88, Set-Up for the APS CD-600 System Serial Number 5973 is a new procedure developed with the purpose to provide guidance on the sets up, performance of preoperational checks, and tests on the equipment prior to processing evaporator concentrates.

Procedure 76RP-0RW89, Operation of the APS CD-600 System Serial Number 5973 is a new procedure developed with the purpose to give guidance on the processing of evaporator concentrates to provide reasonable assurance the free liquid criteria for waste disposal is met. These new procedure are considered within the scope of the PCP, and represent a change in the scope of the PCP as described in step 3.7.2.2. The addition of 76RP-ORW88 and 76RP-0RW89 is a reportable change to the PCP and requires review and acceptance by the Plant Review Board and approval by the Director of Radiation Protection.

An evaluation of a reportable change is required in accordance with UFSAR 13.5.2.2.E. The evaluation will contain sufficient information to support the change together with the appropriate analyses or evaluations justifying the change and a determination that the change will maintain overall conformance of the solidified waste product to the existing requirements of Federal, State, or other applicable regulations.

The scope of the PCP is being changed due to the addition of two new procedures to the program. Procedure 76RP-0RW88, Set Up for the APS CD-600 System Serial Number 5973 is a new procedure developed with the purpose to provide guidance on the sets up, performance of preoperational

checks, and tests on the equipment prior to processing evaporator concentrates. This procedure does not contain processing parameters that will impact the waste characteristics of the final product; therefore, the change does not impact the conformance of the waste product to the existing requirements of Federal, State, or other applicable regulations. Procedure 76RP-0RW89, Operation of the APS CD-600 System Serial Number 5973 is a new procedure developed with the purpose to give guidance on the processing of evaporator concentrates to provide reasonable assurance the free liquid criteria for waste disposal is met in accordance with the existing requirements of Federal, State, or other applicable regulations. The processing parameters for the CD-600 System Serial Number 5973 are identical to the processing parameters employed for the transfer of evaporator concentrates from the original CD-600 System Serial Number 4969. The use of these established processing parameters will provide reasonable assurance the free liquid criteria is met.

10 CFR 50.59 Screening and Evaluation, S-06-0462, was performed to review the use of the mobile RWE NUKEM Corporation CD-600 Solid Radwaste Processing System in 2006. This processing system is still used at Palo Verde and is further designated with the serial number 4969. RWE NUKEM was acquired by EnergySoultions, and the EnergySolutions CD-600 serial 5973 is essentially the same design with upgraded instrumentation and electronics such as human machine interface screens and program logic control.

In accordance with 93DP-OLC07-01, 10 CFR 50.59 and 72.48 Administrative Guideline, step 5.2.1.1 .b, no further screening is required since the two pieces of equipment are similar in design and perform the same function. The technical arguments to support S-06-0462 are correct for the set up and operation of both CD-600 systems.

76RP-0RW78, R 0, "CD-600 System Setup" 76RP-0RW79, R 1, "CD-600 System Operations" RESPONSE JUSTIFICATION INTRODUCTION:

The RWE NUKEM CD-600 solid radwaste processing system (CD-600) is an upgrade to the portable CD- 1000 solid radwaste processing model used at PVNGS. Because of the abandonment-in-place of the original installed Hittman system (per SARCN

  1. 3476 in 1994), PVNGS can currently only process radioactive concentrates using temporary, portable technologies. Succinctly, processing through both systems occurs after liquid waste is reduced in volume to the capabilities of the installed LRS system and is collected in the form of concentrates in the Concentrate Monitor Tanks (CMTs). These concentrates are held and recirculated until they can be transferred through the truck connection valve (SRN-VI 11) via the Wet Waste Processing Subsystem (described in section UFSAR 11.4.2) of the Solid Waste Management System. Waste is then transferred to a processing system (in this instance the CD-600) designed to create a final product that meets the PVNGS PCP. As per UFSAR section 11.4.2.3, complete waste processing is LAW 76DP-ORP03, "Radwaste Process Control Program."

Use of the CD-1000 was evaluated in February of 2002 IAW the 10CFR50.59 evaluation process as implemented by site procedure 93DP-OLCO7, "10 CFR 50.59 and 72.48 Screenings and Evaluations." At the time the evaluation was performed, it was determined that the connection of the CD-1000 to PVNGS systems "screened out" of the IOCFR50.59 process by reasons cited in an Applicability Determination (AD) documented in letter 115-02371 -TSG/MHS (attachment). Specifics of this AD identified that connecting a mobile waste processing system does not constitute a temporary or permanent change to the power production facility as per section 1.2 and the flow chart in Appendix D of 93DP-OLCO7, Revision 5. This Screening coheres to the findings of the 2002 AD as it applies to connecting the CD-1000 to plant systems and extends the AD to include the connection of the CD-600, which is similar to the CD- 1000 in design and identical in its interface with plant systems. However, questions have arisen as to whether or not the very presence and use of a portable solid waste processing system at PVNGS:

1. Changes a design function as per Regulatory Guide 1.143, "Design guidance for Radioactive Waste Management Systems, Structures and Components Installed in Light-Water-Cooled Nuclear Power Plants,"
2. Constitutes an "unreviewed safety question" as per IE Circular 80-18, "10CFR50.59 Safety Evaluations for Changes to Radioactive Waste Treatment Systems,"
3. Requires a revision to an evaluation described in the PVNGS UFSAR,
4. Produces a final waste form that conforms to the PVNGS Process Control Program (PCP) lAW UFSAR 11.4.2.

Section 1.8 of the UFSAR commits PVNGS to Regulatory Guide 1.143 with exceptions. The CD-600 is constructed by RWE NUKEM to meet the guidance of ANSI/ANS-40.37-1993, "Standard for Low-Level Radioactive Waste Processing Systems," and the intent of R.G. 1.143. As a mobile radioactive waste processing system, the CD-600 meets the quality criteria of R.G. 1.143 as part of NUKEM's contractual agreement with PVNGS.

IEC 80-18, "1 OCFR50.59 Safety Evaluations for Changes to Radioactive Waste Treatment Systems" was written in August of 1980 and is still active and endorsed by HPPOS-086. IEC 80-18 instructs compliance with elements of 10CFR50.59 that are not in the current (Oct 4, 1999), amended (Dec 14, 2001) revision of IOCFR50.59. For instance, the term "unreviewed safety question" is no longer used, and documented screenings and applicability determinations were not part of 50.59 in 1980. Functionally, it is apparent that the intent of 80-18 was to reinforce the requirements of IOCFR50.59 which were not generally being applied to radioactive waste treatment systems across the industry. It is the position of PVNGS Radiological Engineering that the proper way to implement IEC 80-18 is by strictly adhering to the 50.59 process in its current revision as implemented by procedure 93DP-OCLO7, with the following specifically considered in the evaluation:

  • The need for PRB review per UFSAR - PRB review is necessary for this action as discussed in answering question 2.
  • Evaluation against Regulatory Guide 1.143 - In this action, all PVNGS radwaste SSCs are used in accordance with their design functions (note previous discussion on LRS, SRS and Wet Waste Subsystem). As previously discussed, the CD-600 meets the intent of R.G. 1.143.

- The Effluent Monitoring Program is implemented at PVNGS per 74DP-9CY08, "Radiological Monitoring Program."

Operation of the CD-600 is within the Radwaste Building and is therefore bounded by in-plant RMS monitoring. No additional monitoring is necessary, nor is a change necessary to the ODCM. IEC 80-18 also requires that this action be bounded for uncontrolled releases to a small fraction of the 10CFRI00 guidelines. This bounding is discussed in depth in answering question I.

76RP-0RW78, R 0, "CD-600 System Setup" 76RP-0RW79, R 1, "CD-600 System Operations" RESPONSE JUSTIFICATION The following UFSAR requirements were also considered during this screening:

TRM 5.0.500.4, "Radioactive Effluent Controls Program" promulgates the PVNGS ODCM and effluent release limits to members of the public. As previously discussed, effluents from the CD-600 are through the RW Building ventilation system, which is monitored. No changes to the ODCM are necessary as a result of this action. Catastrophic release is bounded by PVNGS UFSAI, 15.7.2, 15.7.3 and 2.4.13.

Table 9.5-1 of the UFSAR addresses the issue of fire protection in the Radwaste Truck Bay where the CD-600 is operated.

Notably, the area is not designated as a safety-related area as per UFSAR 9B.2.10.2. The only consequence of a fire might be the release of the contents of the evaporator body, which is bounded by PVNGS UFSAR, 15.7.2, 15.7.3 and 2.4.13.

TRM 5.0.500.17, "Process Control Program (PCP)," requires the maintenance of a PCP program. Changes will be initiated to 76DP-0RP03, "Radwaste Process Control Program," section 3.1.1 to add new CD-600 procedures, 76RP-0RW78, "CD-600 System Setup," and 76RP-0RW79, "CD-600 System Operations."

TLCO 3.10.200, "Liquid Holdup Tanks," imposes a 60 Curie limit to all outdoor radwaste tanks that are not surrounded by liners, dikes, or walls. The CD-600 will be operated inside the Radwaste Building and is therefore, not subject to this limit. However, even if the CD-600 were used outside, it would not reach the 60 Curie limit. Using the UFSAR maximum inventories for the CMTs from Table 12.2-5, a total curie content of approximately 866 Curies can be derived. Since the CD-600 can hold only 1/50 of the contents of the CMT, the maximum curie content for the CD-600 would be below 18 Curies.

QUESTIONS:

Question 1) Does the proposed activity adversely affect a design function described in the UFSAR? NO The design bases for the Liquid and Solid waste management systems that might be challenged by this action are described in Sections 11.2.1.C (IOCFR50 Appendix I release limits) and 11.4.1.A (SRS process capabilities) of the UFSAR. As per the introduction, the CD-600 is constructed by RWE NUKEM under a Quality Assurance Program that meets ANSI/ANS-40.37-1993 and the intent of R.G. 1.143 and provides the capability to process and package wet waste. Therefore, this activity does not adversely affect the design function of the SRS described in 11.4.1 .A.

Stated as part of the design basis in section 11.2.1 .C, is the consideration of the effect of LRS design on dose to the public within 50 miles of the site (per IOCFR50 Appendix I). While the CD-600 is technically not part of the LRS, it is processing liquid radwaste; therefore, the impact of its operation on dose to the public should be considered pursuant to NEI 96-07 and 10CFR50.59.

The CD-600 evaporator chamber processes concentrates in batches received from the CMTs. While the CMTs each hold 5,000 gallons of concentrates, the CD-600 can only process 100 gallons (200 for the CD-1000) at any given time. Each batch is dried and the product drummed in DOT-7A containers prior to receiving another subsequent batch. Since the CD-600 is located in the RW Building and all liquids would be captured by the designed berms and drain system, gaseous release from such an accident is of primary concern. During normal operation the CD-600 vents to the RW Building ventilation system, hence any release of radioactive material from the CD-600 is monitored and quantified by the plant RMS system and station procedures. In the event of a leak, the consequences of a complete breach of the CD-600 could easily be bounded by determining the consequences of a postulated rupture of a CMT (which could contain 50 times more activity than the CD-600). During licensing, PVNGS chose to use a Refueling Water Tank (RWT) rupture as its bounding Liquid Tank Failure in UFSAR sections 15.7.2 and 15.7.3. This was found acceptable to the NRC as noted in Q&A 15A.4 (NRC Question 460.19); however, the NRC did perform an analysis of a rupture in our CMTs per Standard Review Plan (NUREG-0800) SER 15.4.9. The conclusions reached in UFSAR SER 15.4.9 were that a catastrophic failure of the CMT would result in dose to the public <1% of applicable 10CFR20 limits. The analysis in UFSAR 15.7.3.4 demonstrates that a catastrophic failure of the RWT would result in dose to the public <1% of applicable 10CFRI00 limits. In both scenarios, dose to the public within 50 miles is maintained within the limits of IOCFR50, Appendix I.

76RP-0RW78, R 0, "CD-600 System Setup" 76RP-0RW79, R 1, "CD-600 System Operations" RESPONSE JUSTIFICATION Hence. normal operation as well as the consequence of a catastrophic rupture of the CD-600 is bounded by existing analysis and will not adversely affect the design basis cited in UFSAR 11.2,1.

The description of the Low Level Storage Area (LLSA) in section 11.4.2 identifies that, by design, there is 350 square feet of usable floor area in the LLSA. Operation of the CD-600 constitutes an appropriate use of this floor space. Therefore, the presence of the CD-600 does not constitute a condition adverse to the design of the LLSA.

UFSAR ALARA design Table 12.1-1 identifies the design radiation zones for areas within the plant. Drawing 13-N-RAR-002 shows that the Low Level Storage Area, in which processing and temporary storage occur, is a radiation zone 3 with design dose rates below 2.5 mR/hr. Drums of processed wet waste with dose rates of several hundred mRen/hr have been produced at PVNGS using the CD-1000. Drums of waste are temporarily posted, then shielded by placing them in large shielding containers.

A review of routine area radiation surveys indicates that the general area in the Low Level Storage Area has consistently been maintained below 2 mR/hr and excursions above 2.5 mR/hr have been temporary, with posting and access control JAW the PVNGS RP Program. Therefore, the processing of waste with the CD-600 does not constitute a condition adverse to the designed radiation zone 3 designation for the LLSA.

Question 2) Does the proposed activity adversely affect the method of performing or controlling a design function described in the UFSAR? NO The methods of performing and controlling the design functions identified in USFAR 11.2.1 and 11.4.1 for the LRS and SRS are contained in the site PCP (see answer to question 1). Because the CD-600 is marginally different than the CD-I1000, new procedures have been written for the setup and operation of the unit. Setup of the CD-600 is lAW new procedure 76RP-0RW78, "CD-600 System Setup," and operation is lAW 76RP-0RW79, "CD-600 System Operations." Procedures for Radioactive Waste Management are identified in UFSAR 13.5.2.2.E. Accordingly, changes to the PCP must be reviewed by the Plant Review Board (PRB) prior to becoming effective, lAW 76DP-0RP03, "Radwaste Process Control Program," step 3.7.1.1 states:

Any change in processingparametersthat could cause an alterationin the final waste productcharacteristics (e.g., changing: minimum dewateringIdrying times or temperatures,processingtime or temperaturefor concentrate evaporation,vendors, or methodsfor processing liquid waste, etc.).

Because the CD-600 will reduce processing times and will process smaller volume batches, the use of the CD-600 requires PRB approval. PRB approval for the use of the CD-600 is also conservatively necessary per 13.4.2.6 (h), as this action may be perceived to be a "major change" to the solid waste treatment system.

76DP-ORP03, "Radwaste Process Control Program" will require an administrative change to include the CD-600 procedures to section 3.1.1, "PCP Procedures." However, by design, the CD-600 will produce the same final waste product as that produced by the CD-1000. Therefore, this action does not adversely affect the method of performing or controlling the design function of the LRS and the SRS as described in the UFSAR.

Question 3) Does the proposed activity replace or adversely revise an evaluation or method of evaluation described in the UFSAR? NO Evaluations relevant to this action are those concerning the wet waste product waste form (per PCP) and those involved in determining the consequences of an uncontrolled release in the form of a rupture of the CD-600 evaporator.

CD-600 product waste form is per 76DP-ORP03, "Radwaste Process Control Program," lAW NRC Technical Position on Waste Form, Rev 1, January 1991, 10CFR61, IOCFR71 and other pertinent publications. Administrative changes to the PCP resulting from this action are pending as discussed in the answer to question 2.

76RP-0RW78, R 0, "CD-600 System Setup" 76RP-ORW79, R 1, "CD-600 System Operations" RESPONSE JUSTIFICATION PVNGS used a Refueling Water Tank (RWT) rupture as its bounding evaluation for a Liquid Tank Failure in UFSAR sections 15.7.2 and 15.7.3. The consequence to ground water of this postulated rupture is addressed in UFSAR section 2.4.13. The evaluation for this Liquid Tank Failure is contained in Calculation 13-NC-ZY-202. The resulting analysis in section 15.7.3.4 demonstrates that a gaseous release from catastrophic failure of the RWT would result in a dose to the public of<l% of IOCFR100 limits. Consequently, this activity is bounded by existing UFSAR analysis and will not require any revision to supporting calculations. Hence, this activity does not replace or adversely revise any evaluation or method of evaluation described in the UFSAR.

Question 4) Does the proposed activity involve a test or experiment not described in the UFSAR, where an SSC is used or controlled in a manner that is outside the reference bounds of the design for the SSC or is inconsistent with analyses or descriptions as provided in the UFSAR? NO Initial Radwaste system testing criteria for the installed SSCs are located in UFSAR 14.B.48. The CD-600 is not subject to these test criteria, but must meet ANSI/ANS-40.37 and the relevant provisions of R.G. 1.143. All tests and experiments involved in the proper classification of wet wastes are identified in the PCP and its implementing procedures IAW TRM 5.0.500.17. Tests and experiments involved in the PCP are not specifically delineated in the UFSAR: however, they are consistent with analyses and descriptions within the reference bounds of the radioactive waste systems' design and will not be modified as a result of this action.

Question 5) Does the proposed activity require a change to the Technical Specifications? NO There are no Technical specifications directly associated with connecting or operating a mobile radioactive waste processing unit.

TS 5.7, "High Radiation Area," prescribes the administrative controls for High Radiation Areas at PVNGS. These controls are implemented by the PVNGS RP Program. As discussed in Question 1, the LLSA is subject to excursions in dose rates when processing wet waste with the CD-600. Transitory High Radiation Areas are dealt with by shielding or moving the source to an appropriate storage area and/or by posting and controlling access. No Change is required to TS 5.7.
