SUMMARY

A. Discussion

1. Effluent Controls The H. B. Robinson Steam Electric Plant (HBRSEP), Unit No. 2, Offsite Dose Calculation Manual specifies controls and dose limits pertaining to releases of radioactivity to the environment. None of these controls or dose limits were exceeded during 2005.

2. Protection Standards The main objective in the control of radiation is to ensure that any exposure is kept not only within regulatory limits, but As Low As Reasonably Achievable (ALARA). The ALARA concept applies to reducing radiation exposure both to workers at HBRSEP, Unit No. 2, and to the general public. "Reasonably achievable" means that radiation exposure reduction is based on sound environmental practices, economic decisions, and operating practices. By practicing ALARA, HBRSEP and Progress Energy Carolinas, Inc., minimize health risk and environmental detriment, and ensure that exposures are maintained well below regulatory limits.

3. Sources of Radioactivity Released During normal operations of a nuclear power station, most of the fission products are retained within the fuel and fuel cladding. However, small quantities of radioactive fission and activation products are present in the reactor coolant water.

The types of radioactive material released are noble gases, iodines and particulates, and tritium.

The noble gas fission products in the reactor coolant water are released as a gas when the coolant is depressurized. These gases are collected by a system designed for collection and storage for radioactive decay prior to release to the environment.

Small releases of radioactivity in liquids may occur from equipment associated with the reactor coolant system. These liquids are collected and processed for radioactivity removal, prior to and during release.

4. Noble Gas Some of the fission products released in airborne effluents are radioactive isotopes of noble gases, such as krypton, argon, and xenon. Noble gases are by nature inert and do not concentrate in humans or other organisms. Noble gases contribute to human radiation exposure as external exposure.

5. lodines and Particulates There were no measurable releases of iodine during the year. Annual releases of particulates with half-lives greater than eight days were small. Factors such as chemical reactivity and solubility in water, combined with high processing efficiencies, minimize their discharge. The main contribution of radioactive iodine to human exposure is to the thyroid gland, where the body concentrates iodine. The particulates contribute to internal exposure of tissues such as the muscle, liver, and intestines. These particulates can also be a source of exposure if deposited on the ground.

6. Tritium Tritium, a radioactive isotope of hydrogen, is the predominate radionuclide in liquid and gaseous effluents. Tritium is produced in the reactor via a number of processes. Tritium is a weak beta particle emitter and contributes very little radiation exposure to the human body, and when tritium is inhaled, ingested, or absorbed it is dispersed throughout the body until eliminated.

7. Processing and Monitoring Effluents are strictly controlled and monitored to ensure that radioactivity released to the environment is minimal and within regulatory limits. Effluent controls include the operation of radiation monitoring systems, in-plant and environmental sampling and analyses, quality assurance programs for both in-plant and environmental sampling and analyses, and procedures that address effluent and environmental monitoring.

The plant radiation monitoring system provides monitors that are designed to ensure that all releases are below regulatory limits. Each instrument provides indication of the amount of radioactivity present and is equipped with alarms and indicators in the control room. The alarm setpoints are set below the regulatory limits, i.e., typically at less than 50 percent of the regulatory limit, to ensure that the limits are not exceeded. If a monitor alarms, a release to the environment from a tank is automatically suspended. Additionally, releases are sampled and analyzed in the laboratory prior to discharge to the environment. The sampling and analysis done in the laboratory provides a more sensitive and precise method of determining pre-effluent composition than in-plant monitoring instruments.

The plant has a meteorological tower, which is linked to computers that record the meteorological data. This meteorological data and the results of the Land Use Census are used to verify the ground level dispersion factors contained in the ODCM that are used in calculating the dose to the public.

United States Nuclear Regulatory Commission Attachment to Serial: RNP-RA/06-0034 Page 6 of 38 In addition to in-plant equipment, the company maintains a Radiological Environmental Monitoring Program, which consists of devices used to sample the air and water in the environment. The samples collected from the surrounding environment are analyzed to determine the presence of radioactive material in the environment.

8. Exposure Pathways Radiological exposure pathways are the methods by which people may become exposed to radioactive material. The major pathways of concern are those which could cause the highest calculated radiation dose. The projected pathways are determined from the type and amount of radioactive material that may have been released, the environmental transport mechanism, and the use of the environment.

Environmental transport mechanisms include, but are not limited to, hydrological (i.e., water) and meteorological (i.e., weather) characteristics of the area.

Information on water flow, wind speed and direction, dietary intake of residents, recreational use of the area, and location of homes and farms in the area are some of the many factors used to calculate the potential exposure to offsite personnel.

The release of radioactive gaseous effluents includes pathways such as external whole body exposure, deposition on plants and soils, and human inhalation. The release of radioactive material in liquid effluents includes pathways such as fish consumption, and direct exposure from the lake at the shoreline and while swimming.

Even though radionuclides can reach humans by many different pathways, some radionuclides result in more exposure than others. The critical pathway is the one that, for a specific radionuclide, will result in the greatest exposure to a population, or a specific group of the population, called the critical group. The critical group may vary depending on the radionuclides involved, the age and diet of the group, and other cultural factors. The exposure may be received by the whole body or to a specific organ, with the organ receiving the largest fraction of the exposure called the critical organ.

The exposures to the general public in the area surrounding HBRSEP, Unit No. 2, are calculated for gaseous and liquid releases. The exposure due to radioactive material released in gaseous effluents is calculated using factors such as the amount of radioactive material released, the concentration beyond the site boundary, locations of exposure pathways, and usage factors. The exposures calculated due to radioactive materials released in liquid effluents are calculated using factors such as the total volume of liquid, the total volume of dilution water, field irrigation, and usage factors.

9. Results The Radioactive Effluent Release Report is a detailed listing of the radioactivity released from the HBRSEP, Unit No. 2, during the period from January 1, 2005 through December 31, 2005.

During the period of January 1, 2005 through December 31, 2005, the estimated maximum individual offsite dose due to radioactivity released in effluents was:

Liquid Effluents:

Total Body Dose 0.0000919 millirem

Critical Organ Dose 0.0000957 millirem, Liver Gaseous Effluents:

Beta Air Dose 0.00355 millirad

Gamma Air Dose 0.00972 millirad

Critical Organ Dose 0.0739 millirem, Lung B. Significant Variances The following are explanations of significant variances in this Annual Report:

1. The 10 CFR 50, Appendix I, doses were calculated using the Canberra Effluent Management System (EMS'). The EMS Software provides day-by-day dose estimates that are conservative because all releases are assigned to the limiting receptor, using the continuous ground level dispersion factors calculated from 1978 meteorology.

2. HBRSEP, Unit No. 2, operated continuously throughout 2005 with the exception of the refueling shutdown from September 17, 2005 until October 25, 2005.

Continued good fuel and reactor coolant system integrity kept gaseous and liquid effluent totals relatively low in 2005. Some of the gaseous and liquid release parameters for this reporting period are summarized below:

EMS, Effluent Management System Software is a product of Canberra Nuclear Industries used for determining curies and dose released from routine radioactive effluent releases.

Regulatory Compliance

1. When projected on a day-by-day basis, utilizing conservative meteorological conditions, the dose commitment from gaseous and liquid effluents is a small fraction of the 10 CFR 50, Appendix I, limits. The direct radiation assessment to the most likely exposed member of the public is reported in the Annual Radiological Environmental Operating Report. During 2005, the results of the direct radiation assessment demonstrated no measurable effect above background for plant operations.

2. There were no changes to the waste solidification Process Control Program (PCP) during this reporting period. See page 35.

3. There were no changes to the Radioactive Waste Systems (i.e., liquid, gaseous, or solid) during this reporting period. See page 35.

4. There was one reportable instrumentation inoperability event during this reporting period. See page 35.

5. There were no outside liquid holdup tanks that exceeded the 10 curie limit during this reporting period. See page 35.

United States Nuclear Regulatory Commission Attachment to Serial: RNP-RA/06-0034 Page 10 of 38 B. Measurements and Approximations of Total Radioactivity

1. Continuous Gaseous Releases a) Fission and Activation Gases - The total activity released is determined from the net count rate of the gaseous monitor, its calibration factor, and the total exhaust flow. The activity of radioactive gas is determined by the fraction of that radioactive gas in the isotopic analysis for that period.

b) lodines - The activity released as Iodine-131, 133, and 135 is based on isotopic analysis of the charcoal cartridge and particulate filter, and the total exhaust flow.

c) Particulates - The activity released via particulates with half-lives greater than eight days is determined by isotopic analysis of particulate filters and the total exhaust flow.

d) Tritium - The activity released as tritium is based on weekly grab sample analysis and total exhaust flow.

2. Batch Gaseous Releases a) Fission and Activation Gases - The activity released is based on the volume released and the activity of the individual nuclides obtained from an isotopic analysis of the grab sample taken prior to the release.

b) Iodines - The iodines from mixed mode batch releases are included in the iodine determination from the mixed mode continuous Reactor Auxiliary Building release.

c) Particulates - The particulates from mixed mode batch releases are included in the particulate determination from the mixed mode continuous Reactor Auxiliary Building release.

d) Tritium - The activity released as tritium is based on the grab sample analysis of each batch and the batch volume.

United States Nuclear Regulatory Commission Attachment to Serial: RNP-RA/06-0034 Page 11 of 38

3. Liquid Releases a) Fission and Activation Products - The total release values (not including tritium, gases, and alpha) are comprised of the sum of the individual radionuclide activities in each release to the discharge canal for the respective quarter. These values represent the activity known to be present in the liquid radwaste effluent.

b) Tritium - The activity released as tritium is based on the grab sample analysis of each batch and the batch volume. For continuous releases, the activity released as tritium is based on analysis of a weekly composite sample. For continuous releases without a composite sampler, the tritium activity is based on analysis of daily grab samples.

c) Alpha - The measured alpha concentration in a monthly composite sample is used to calculate the total release and average diluted concentration during each period.

d) Strontium-89, 90, and Iron The total release values are measured quarterly from composite samples.

C. Estimated Total Errors

1. Estimated total errors for gaseous effluents are based on uncertainties in counting equipment calibration, counting statistics, exhaust flow rates, exhaust sample flow rates, non-steady release rates, chemical yield factors, and sample losses for such items as charcoal cartridges.

2. Estimated total errors for liquid effluents are based on uncertainties in counting equipment calibration, counting statistics, non-steady release flow rate, sampling and mixing losses, and volume determinations.

3. Estimated total errors for solid waste are based on uncertainties in equipment calibration, dose rate measurements, geometry, and volume determinations.

United States Nuclear Regulatory Commission Attachment to Serial: RNP-RA/06-0034 Page 30 of 38 VI. 40 CFR 190 DOSE CONFORMANCE The direct radiation assessment to the most likely exposed member of the public is reported in the Annual Radiological Environmental Operating Report. The results of the assessment demonstrate no measurable affect above background from plant operations. Since no 10 CFR 50, Appendix I, limits have been exceeded and the evaluation of the Independent Spent Fuel Storage Installations indicate only a small fraction of the total dose to the environs, this demonstrates conformance with 40 CFR 190, 'Environmental Radiation Protection Standards for Nuclear Power Operation."

VII. METEOROLOGICAL DATA A. Continuous Release Diffusion Analysis Table VII-A presents the number and frequency of wind direction occurrences by wind speed class as recorded at the onsite meteorological system during continuous release, for the period January 1, 2005, through December 31, 2005.

The frequencies are presented as a percent of total occurrences for each stability class, as well as a summary for all classes for the lower (11 meter) sensor elevation.

Pertinent information available from the tables is as follows:

1. Stability Percent occurrence Pasquill Stability categories based on lower level (11 meter) wind distribution:

A B C D E F G 4.19 5.81 7.89 44.32 19.97 8.75 9.07

2. Wind Speed 11 Meter Average Speed (mph) 4.26 Percent Calm 7.98 Percent Less than 3.5 mph 48.25

United States Nuclear Regulators Commission Attachment to Serial: RNP-RA/06-0034 Page 34 of 38 I. CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL (ODCM)

There were two revisions to the ODCM during this reporting period. Summaries of the revisions are shown below. A complete copy of the updated ODCM is being submitted in a separate letter.

ODCM, Revision 26 Description of Changes There were several changes made to the ODCM in Revision 26. These changes were in support of the new 24P-ISFSI module that was installed. These changes include:

1) Revised description for sample point 56 on Table 4.5-1 & footnote 10 on Table 4.5-1 to add '7P" to the ISFSI in order to distinguish the present ISFSI structure licensed under SNM-2502 from the new 24P-ISFSI under CoC No. 1004.

2) Added two new TLDs (sample points 61 & 65) to Table 4.5-1 which will be used to monitor the 24P-ISFSI.

3) Added a new footnote (11) to Table 4.5-1 which denotes that the referenced sample is required for monitoring of the 24P-ISFSI.

4) Added footnote 11 to TLD sample points 2, 6, 56, 61, and 65 on Table 4.5-1. This addition will designate the environmental TLDs that will be used for monitoring direct radiation from the 24P-ISFSI as required by 10 CFR 72.126(c)(2).

5) Modified Figure 4-1, "Radiological Sample Locations Near Site," as follows:

a. Modified railroad track layout to reflect recent changes to the track.

b. Added sample point 65.

c. Moved sample points 2, 56, and 61 to more accurately reflect the true sample points.

d. Added sample points 61 & 65 to the TLD samples on the table below the map.

e. Removed redundant statement regarding which sample points have TLDs and air samplers. This information is already available in the table below the map.

f. Added 24P-ISFSI module to the map.

6) Modified Figure 4-2, "Radiological Sample Distant Locations," as follows:

a. Added sample points 61 & 65 to the TLD samples on the table below the map.

b. Added sample location 65 to the list of samples not shown on the map due to the map scale.

c. Removed redundant statement regarding which sample points have TLDs and air samplers. This information is already available in the table below the map.

United States Nuclear Regulatory Commission Attachment to Serial: RNP-RA/06-0034 Page 35 of 38 ODCM, Revision 27 Description of Changes

1) Several changes were made to the ODCM following the replacement of the plant vent stack radiation monitor, R-14. The new R-14 eliminated channels A & B, which were originally used to monitor for particulates and iodine. Sections 3.7 & 3.8 detailing the methodologies to determine the alarm setpoints of R-14A & R14B were deleted. Additionally, the surveillance requirements associated with these channels have been deleted from Table 3.11-1, Item l.a & l .b (Radioactive Gaseous Effluent Monitoring Instrumentation Surveillance Requirements).

2) Added descriptive sample points to Table 3.12-1 (Radioactive Gaseous Waste Sampling and Analysis Program) further detailing the gaseous effluent monitoring program that is currently in place.

3) Deleted Note i from Table 3.12-1 (Radioactive Gaseous Waste Sampling and Analysis Program). This note required the daily sampling for plant vent particulate and iodine if particulate and iodine levels exceed 10% of the limits in Section 3.2.1. This requirement is not contained in Generic Letter 89-01, NUREG-1301, "Offsite Dose Calculation Manual Guidance: Standard Radiological Effluent Controls for Pressurized Water Reactors."

4) Deleted reference to the condenser vacuum pump radiation monitor (R-15) in reference to its use in monitoring for a primary-to-secondary leak. This is a primary-to-secondary leak programmatic statement which does not need to be included in this document.

II. CHANGES TO THE RADIOACTIVE WASTE SYSTEMS There were no changes to the Radioactive Waste Systems during this reporting period.

HI. CHANGES TO THE PROCESS CONTROL PROGRAM (PCP)

There were no changes to the Process Control Program during this reporting period.

IV. CHANGES TO THE LAND USE CENSUS The Land Use Census is performed every 24 months and was last performed in 2004. The results of the 2004 Land Use Census and average meteorological data for the last 10 years identified no changes that require an ODCM change. The next Land Use Census will be performed in 2006.

V. INSTRUMENT INOPERABILITY Due to a discrepancy in hydrogen readings between a grab sample and the waste gas analyzer, the waste gas analyzer was removed from service on November 21, 2005, at 1446 hours0.0167 days 0.402 hours 0.00239 weeks 5.50203e-4 months . TRM 3.11, Item A.2, requires the return of the waste gas analyzer to service within 14 days. Contrary to this requirement, due to continuing problems with the gas analyzer and failure to adequately communicate its out of service time, the waste gas analyzer was not returned to service until January 20, 2006, at 1352 hours0.0156 days 0.376 hours 0.00224 weeks 5.14436e-4 months . This event was investigated under Corrective Action Program Nuclear Condition Report (NCR) 177865.

VI. LIQUID HOLDUP TANK CURIE LIMIT There were no outside liquid holdup tanks that exceeded the ten curie limit during this reporting period.

United States Nuclear Regulatory Commission Attachment to Serial: RNP-RA/06-0034 Page 36 of 38 VII. WASTE GAS DECAY TANK CURIE LIMiT There were no waste gas decay tanks with a curie content that exceeded the 1.90E+04 curie limit during this reporting period.

VIII. MISSED COMPENSATORY SAMPLES In 2005, there were three instances when compensatory sampling as required by the ODCM was not performed. These three events were investigated under Significant Adverse NCR 177293.

1) On November 2, 2005 at 2020 hours0.0234 days 0.561 hours 0.00334 weeks 7.6861e-4 months , the Condensate Polisher Liquid Waste Monitor (R-37) flow monitor was declared out of service and Work Request 215389 was initiated. Due to a lack of training and procedure guidance, it was not recognized that inoperability of the flow monitor results in the R-37 monitor also becoming inoperable. Consequently, the required compensatory grab sampling of ODCM 2.6, Table 2.6-1, Item 7, was not performed until November 5, 2005, at 0227 hours0.00263 days 0.0631 hours 3.753307e-4 weeks 8.63735e-5 months , when it was recognized that R-37 had become inoperable.

2) On November 17, 2005 at 0910 hours0.0105 days 0.253 hours 0.0015 weeks 3.46255e-4 months , a compensatory grab sample for the plant vent stack radiation monitor (R-14) was obtained 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months and 10 minutes after the previous sample.

This does not meet the required frequency of ODCM Table 3.10-1, Item 1.b, which requires that samples be collected at least once per 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months .

3) On November 28, 2005, the required compensatory sampling for the Fuel Handling Building Lower Level Exhaust radiation monitor (R-20) being out of service was not performed as required by Table 3.10-1, Item 3.a. A failure of a detector in the count room resulted in an invalid spectrum on the sample collected at 0744 hours0.00861 days 0.207 hours 0.00123 weeks 2.83092e-4 months on November 28, 2005. As a result, the time between valid samples was 13 hours1.50463e-4 days 0.00361 hours 2.149471e-5 weeks 4.9465e-6 months and 2 minutes. This exceeds the ODCM requirement for samples collected every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months , and analyzed within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .
