I Onsite Groundwater Monitoring: Twenty-three (23) on-site monitoring wells were sampled in both I
sampling periods in 2011. No new wells were installed and no wells were retired. Fifteen (15) wells were less than the pre-operational mean (440 pCi/L) during all sample periods in 2011. Two (2) wells were >440 pCi/L, but <2000 pCi/L. Six (6) wells were >2000 pCi/L, but <30,000 pCi/L with only a single well (MW-I
: 16) >20,000 pCi/L. The NEI/FENOC communication level was reached for MW-12S & MW-12D during 2007. Notification to local, state & federal agencies was performed on 10/08/07. Additional communication for new well results was performed on 09/08/10 for those new wells that exceeded 2000 pCi/L. There were             I no wells that reached the 2000 pCi/L Communication Level for the first time in 2011. No adverse effect to the offsite environment has been detected at this time, because all offsite groundwater, drinking water and surface water samples were <440 pCi/L.                                                                              I Onsite Spills: There were no onsite spills >100 gallons.
I Decommissioning File Update: Two items were added to the site decommissioning files in accordance with 10CFR50.75(g). These items included extending the condition of onsite groundwater contamination for the new 2010 monitoring wells and the discovery of Licensed Radioactive Material (LRM) in the Unit I and Unit 2 Nitrogen Systems. See Enclosure 2, page xvi for additional details.
I Abnormal Liquid Releases: There were no abnormal liquid releases.
I Abnormal Gaseous Releases: There were no abnormal gaseous releases.
Liquid Radwaste Treatment System: The site operated via a shared Liquid Radwaste Treatment System, I
even though each Unit has its own ion-exchange vessels. Shared operation allowed either Unit to process liquid waste at the Unit of origin, or at the other Unit. Typically, when Unit 1 or 2 high level liquid waste was processed (e.g., coolant recovery waste) it was performed at Unit 1, because it has a carbon pre-conditioning filter.
I Gaseous Radwaste Treatment System: The site operated via a shared Gaseous Radwaste Treatment System, even though each Unit has its own charcoal delay beds and storage/decay tanks. Shared operation I
allowed either Unit to process gaseous waste at the Unit of origin, or at the other Unit. Typically, when Unit I or 2 went to a shutdown condition, the gaseous waste was transferred for storage and decay at Unit 2, because Unit 2 has four (4) additional storage tanks.

Lower Limits of Detectability (LLD): All a-priori calculated LLD met the minimum requirements specified in the ODCM for batch radioactive discharge purposes. One RETS geometry is currently under investigation. See Enclosure 2, pages 15 and 21 for additional details.
Effluent Monitoring Channels Inoperable >30 Days: There were six Effluent Monitoring Instrumentation Channels not returned to Operable status within 30 days. See Enclosure 2, pages 18 and 19 for details.
ODCM Surveillance Deficiencies: There was one ODCM Surveillance Deficiency associated with the LLD requirements for the I Liter Bottle geometry. See Enclosure 2, page 21 for details.
ODCM Changes: There were three changes made to the ODCM during the report period. All changes maintain the level of radioactive effluent control required by 10 CFR 20.1302, 40 CFR Part 190, 10 CFR 50.36a, and Appendix I to 10 CFR 50. Detailed descriptions of the ODCM changes are provided in Enclosure 2, page 22 Table 9 and Attachment 2.
Meteoroloincal Data Recovery: The Meteorological Data Recovery met the minimum requirement of at least 90%, as specified in Section 5 of Revision I to Regulatory Guide 1.23, Meteorological Monitoring Programs for Nuclear Power Plants.
Population Dose vs. Natural 

==Background:==
The 0-50 mile total and average population doses were calculated using liquid and gaseous release quantities and real time meteorology. The average population dose is based on four (4) million people within 0-50 miles of the BVPS site. The following comparison to natural background radiation demonstrates that BVPS operations did not adversely affect the surrounding environment.
376 man-mrem = BVPS Total Population Dose for the year 0.0000941 mrem = BVPS Average Individual Dose for the year 296 mrem = Natural Background Individual Dose for the year. This dose value is documented as natural background radiation exposure for an individual in a year from the 1990 BEIR V Report.
Carbon-14 Dose Assessment: Details of the dose assessment due to releases of Carbon-14 in gaseous effluents are provided in Attachment 3 of this report.

I Trends of Total Dose: The following graph provides a comparison of the ODCM dose projections from all facility releases and direct radiation exposures to show compliance with Member of the Public dose limits from 10 CFR 20.1301 and 40 CFR Part 190. The graph reflects the results of the efforts to stabilize and reduce offsite dose. Engineering improvement projects are ongoing to the Liquid Waste System which have I
caused slight increases in liquid effluents and offsite dose. When the projects are complete and processing techniques are finalized using the new arrangements, trends should return to previous values.                                  I 100.0%

The projections use ODCM default flow rates for the receiving water (Ohio River), and were performed prior to release authorization. The recent increases were due to efforts to reduce overall offsite dose. Specifically, discharging liquid radioactive inventory provided the benefit of reduced total offsite dose, due to reduction in evaporative losses from the fuel pools. Engineering improvement projects are ongoing to the Liquid Waste System, as well, which have caused slight increases in liquid effluents and offsite dose. When the projects are complete and processing techniques are finalized using the new arrangements, trends should return to previous values.

Gaseous Release Activity (Particulates and Radioiodines): The following graph provides a comparison of total gaseous particulates and radioiodines discharged from the site from 1976 to present. The recent variations are due to identification of Co-58 and Co-60 in weekly effluent pathway samples during refueling outages at both Units 1 and 2, while decreasing trends are due to extended hold-up periods of gas space prior to release. (Radioiodines attributed to Fukushima fallout are not included in the totals.)

Item I of 2 (Groundwater Wells): In July 2011, Unit 1 Groundwater Monitoring wells 12s, 12d, 14s, 14d, 15 and 16 were added to the Decommissioning Files per the requirements of 10CFR50.75(g). Previously, in October of 2007, when the first levels of tritium >2000 pCiIL were discovered in monitoring wells 12s and 12d, the groundwater and I
monitoring wells were added to the files at that time. However, the monitoring wells that were newly installed in the Fall of 2010 were not documented until 2011. Reference Condition Reports # 10-82309 and 2011-96782.                              !
Item 2 of 2 (Unit 1 and Unit 2 Nitrogen Systems): In April 2011, the Gaseous Nitrogen Systems at both Unit 1 and Unit 2 were found to be contaminated. Because the UFSAR does not consider the Nitrogen System at either unit to be radioactive, then the cost to decommission the site could be significantly greater than anticipated at plant construction.
I Therefore, a record of this contamination is required to be maintained per the requirements of 10CFR50.75(g).

No new wells were installed and no wells were retired. Fifteen (15) wells were less than the pre-operational mean (440 pCiIL) during all sample periods in 2011. Two (2) wells were >440 pCi/L, but <2000 pCi/L. Six (6) wells were >2000 pCi/L, but <30,000 pCi/L with only a single well (MW
: 16) >20,000 pCi/L. The NEI/FENOC communication level was reached for MW-12S & MW-12D during 2007. Notification to local, state & federal agencies was performed on 10108/07. Additional communication for new well results was performed on 09/08110 for those new wells that exceeded 2000 pCi/L. There were no wells that reached the 2000 pCi/L Communication Level for the first time in 2011. No adverse effect to the offsite environment has been detected at this time, because all offsite groundwater, drinking water and surface water samples were <440 pCi/L.
Mitigation activities (completed on 12/17/11) involved sleeving of deteriorated stormwater piping and repairs of catch basins. The project was performed to allow tritiated process water to be discharged through the catch basin system into the Ohio River as originally designed rather than entering the groundwater.
Principal Gamma Emmltter Summary: Twenty-three (23) onsite monitoring wells were sampled on at least two occasions during thel year and analyzed for Principle Gamma Emitters. The results showed no positive indication of Licensed Radioactive Material (LRM) in any of the analyses. Due to high H-3 concentrations in the six (6) wells previously mentioned, a hard-to-detect analysis was conducted Results from the hard-to-detect analysis also showed no positive indication of LRM.

(2) These LLD calculations contain a default weekly continuous sample volume of 2.85E+8 cc. Therefore, grab sample LLD values reflect a different volume (ie; 10 cuft or 2.83E+5 cc).
(3) The calculated LLD's, except those denoted by (1), are from a counter/detector calibration on  03127111. These values are typical for other counterldetectors used for effluent counting at BVPS.
(4) Based on counting 50 ml of the water that was bubbled through a 20 liter air sample.

They were taken out of service during MSP on 09111110 due to the probe not working as expected.
The design flow of 62,000 cfrn was used for effluent releases during the out of service time period.
This was previously reported in the 2010 ARERR. The current probe design for FR-VS-1 01 is obsolete and replacement parts to return the monitor to service were not available until August I
2011. FR-VS-101 was returned to service on 8/10/11. The alternate channel, RM-1VS-109, Ch 10, remained out of service until 09/02111 due to erroneous readings caused by inaccurate procedural guidance for the maximum scale limit.

rRM-I*A-1001   - Unit I Auxiliairy Feed Pump Bay Drain Monitor On 04/14/11, this monitor was removed from service due to failure of the sample pump. The sample pump had recently been replaced (01/28/11). This pump is a special order item and a replacement pump could not be immediately obtained, therefore the monitor remained out of service for greater than 30 days. The monitor was returned to service on 07/18/11.
As required by ODCM procedure 1/2-ODC-3.03, "Controls for RETS and REMP Programs",
(as referenced in procedure Attachment E, Control 3.3.3.9, Table 3.3-12, Action 24), effluent releases via this pathway may continue provided grab samples are analyzed once per 12 hours. However, SINCE this liquid effluent pathway was diverted to the Tunnel Sump / Liquid Radwaste Treatment System on 04/14/11 (and remained diverted until the monitor was returned to operable status on 07/18/11), THEN there were no liquid releases through this effluent pathway, Therefore, grab sampling was not required.

Pursuant to 10 CFR 20.1301(a)(1), the Total Effective Dose Equivalent from licensed operation to the maximum individual during the report period, is 3.66 mrem. This is a summation of Direct Radiation Exposure (calculated by comparing the maximum of all I
perimeter TLD exposures to TLD exposure at the REMP control location) plus Effluent Doses (calculated per the ODCM).
I The radiation doses for MEMBER(S) OF THE PUBLIC due to their activities inside the site boundary are not greater than the doses listed in this table to show compliance with 40 CFR Part 190 or 10 CFR 20.1301. Evaluations have shown that exposure time for individuals not occupationally associated with the plant site is minimal in comparison to the exposure time considered for the dose calculation at or beyond the site boundary. Therefore, a separate assessment of radiation doses from radioactive effluents to MEMBER(S) OF THE PUBLIC, due to their activities inside the site boundary, is not necessary for this report period.

While the geometry is used for some RETS purposes, it is not the geometry utilized for radioactive batch discharge permits.
The issue with Ce-144 has been a recurring matter and has been addressed with Step 9.2 of BVPS site procedure 1/2-ENV-01.02, LLD Calculations, stating an exception for some isotopes if Cobalt-60 and Cesium-137 LLDs are acceptable. However, 1/2-ODC-3.03, ODCM:
Controls for RETS and REMP Programs, Attachment G states that the LLD specification specifically applies to Ce-144 (among other nuclides) and that unusual circumstances resulting in LLDs higher than required shall be documented in the Radioactive Effluent Release Report. Investigation as to why this isotope cannot pass LLD requirements and associated corrective actions are ongoing and will be documented in Condition Report

ENCLOSURE 2, ATTACHMENT 1 RTL # A9.690E Enclosure 2, Attachment I Beaver Valley Power Station - Units I & 2 Radioactive Effluent Release Report Calendar Year - 2011 Attachment I Joint Frequency Distribution Tables As specified in the ODCM, an annual summary of hourly meteorological data (in the form of joint frequency distribution) is provided for the calendar year. In summary, the joint frequency distribution data is similar to previous years and close to long-term normals for the site area.
The Meteorological Data Recovery for the calendar year met the minimum requirement of at-least 90% (as specified in Section 5 of Revision 1 to Regulatory Guide 1.23, Meteorological Monitoring Programs for Nuclear Power Plants). The actual Meteorological Data Recovery is shown in the following table:
PERCENT RECOVERY OF INDIVIDUAL METEOROLOGICAL PARAMETERS 99.7% = Wind Speed 35' 100% = Wind Speed 150' 99.9% = Wind Speed 500' 100% = Wind Direction 35' 100% = Wind Direction 150' 100% = Wind Direction 500' 100% = Delta Temperature (150'- 35') 1P 100% = Delta Temperature (500'- 35') 2P 100% = Temperature 35' 100% = Precipitation 100% = Average Recovery of Individual Meteorological Parameters PERCENT RECOVERY OF COMPOSITE VARIABLES 100% = Wind Speed 35', Wind Direction 35', Delta Temperature 1P 100% = Wind Speed 150', Wind Direction 150', Delta Temperature 1P 100% = Wind Speed 500', Wind Direction 500', Delta Temperature 2P 100% = Average Recovery of Composite Variables Hourly meteorological data is not provided for specific periods of Abnormal Gaseous Release during the calendar quarters (as indicated in Regulatory Guide 1.21), for the following reasons:
: 1) All routine Gaseous Releases for the calendar year were determined to be within design objectives, where as, the ODCM Dose Limits and the ODCM Dose Rate Limits are considered to be the design objectives.
: 2) There were no Abnormal Gaseous Releases during the calendar year.
