EXECUTIVE

SUMMARY

Connecticut Yankee's Haddam Neck facility was permanently shutdown in 1996. All fuel has been transferred into dry storage casks and placed at the Independent Spent Fuel Storage Installation. The Radiological Environmental Monitoring Program (REMP) for the Connecticut Yankee Independent Spent Fuel Storage Installation (ISFSI) located in East Haddam, CT was continued for the period January through December 2012 in compliance with the Connecticut Yankee Off-Site Dose Calculation Manual (ODCM).

No changes were made to the ODCM during 2012. By design, there are no liquid or gaseous effluents associated with the operation of the ISFSI. Therefore, the ODCM only requires monitoring of direct exposure from the facility. TLDs were used to measure direct gamma exposure at eight locations in the vicinity of the ISFSI and one control location 2.8 miles away. The results of these measurements showed no significant change in exposure rates and potential doses to members of the public during the monitoring period over the baseline measurements that were collected in 2003. The results of the monitoring performed in 2012 also show that operating the Haddam Neck ISFSI results in only a small fraction of the 40 CFR Part 190 and 10 CFR Part 72.104 direct radiation dose limit of 25 mrem/year to members of the public.

2.0 GENERAL ISFSI AND SITE INFORMATION The Haddam Neck ISFSI site is located in the town of East Haddam, Middlesex County, Connecticut, at a point 22 miles south-southeast of Hartford, Connecticut; 25 miles northeast of New Haven, Connecticut; and 16 miles north of Long Island Sound. The site is situated on the east bank of the Connecticut River at an area known as Haddam Neck. The elevation of the site property varies from 10 to 300 feet above sea level, with the area occupied by the ISFSI Pad ranging between 45 and 50 feet above sea level.

The former plant was designed as a single unit pressurized water reactor which sustained its initial chain reaction in July 1967, with commercial operation beginning in January 1968 and a gross power output of 590 Mw (e). After 28 years of operation, the Connecticut Yankee Board of Directors voted in 1996 to permanently close and decommission the power plant. Following two years of planning and preparation, actual decommissioning began in 1998 and was completed in 2006. This site now consists of the Independent Spent Fuel Storage Installation where the fuel from the former plant reactor is stored.

The Radiological Environmental Monitoring Program (REMP) for the ISFSI began pre-operational direct radiation measurements in 2003 prior to the initial spent fuel transfer to the ISFSI. The ISFSI REMP has been in continuous operation since this transfer began.

3.0 PROGRAM DESIGN The Radiological Environmental Monitoring Program (REMP) for the Haddam Neck ISFSI was designed to provide assurance to regulatory agencies and the public that the station's environmental impact is known and within anticipated limits. The direct dose limit for members of the public from operation of the ISFSI is 25 mrem per year (References 3 and 4).

The detailed sampling requirements of the REMP are given in the ODCM. The sampling requirements specified in the ODCM are summarized in Table 3.1 of this report. Details of the monitored locations are shown in Table 3.2, as well as Figure 3.1 of this report.

CY 2012 Annual REO Report Page 7 of 36

3.1 Monitoring Zones The REMP is designed to allow comparison of levels of radioactivity in samples from the area possibly influenced by the ISFSI to levels found in areas not influenced by the ISFSI. The first area is called "indicator stations". The second area is called "control stations". The distinction between the two is based on relative direction from the facility and distance. Analysis of survey data from the two zones aids in determining if there is a significant difference between the two areas. It can also help in differentiating between radioactivity or radiation due to releases and that due to other fluctuations in the environment, such as seasonal variations in the natural background.

3.2 Pathways Monitored Based on the design of the ISFSI, only the direct radiation exposure pathway is monitored by the REMP. This pathway is monitored by the collection of thermoluminescent dosimeters (TLDs) which are described in more detail below.

3.3 Description of the Monitoring Program 3.3.1 Direct Radiation Direct gamma radiation exposure was continuously monitored during 2012 with the use of thermoluminescent dosimeters (TLDs). At each monitoring location, these TLDs are sealed in plastic bags and attached to an object such as a tree, fence or utility pole. The TLDs are posted and retrieved on a quarterly basis. All TLDs are provided and processed by a National Voluntary Laboratory Accreditation Program (NVLAP) certified vendor. The TLDs are placed at various locations around the Independent Spent Fuel Storage Installation (ISFSI). Table 3.2 lists the Station ID Codes, distances and direction of the TLDs from the ISFSI.

3.3.2 Special Monitoring Special samples are taken that are not required in the ODCM. The sample locations do not appear in Table 3.1 or 3.2 of this report. Three Dibble Creek Sediment samples, three ISFSI Outfall soil samples and three ISFSI Runoff water samples were collected during this period. The results of these samples are available for review at the site.

4.0 RADIOLOGICAL DATA

SUMMARY

TABLES This section summarizes the analytical results of the environmental samples, which were collected during the monitoring period.

Data from direct radiation measurements made by TLDs are presented in Table 4.1.

The direct measurements presented in Table 4.1 are converted to exposure rates in the following manner:

o The total TLD exposure time is determined from the anneal and read dates.

o The total deployment time is determined from the placement and retrieval dates.

o The non-deployment time is converted to exposure and subtracted from the TLD reading presented in Table 4.1.

o The resulting net exposure (deployment exposure) is divided by the deployment time in hours to calculate the exposure rate in pR per hour.

o The calculated exposure rates are presented in Table 4.2.

The summarized exposure rate results, shown in Table 4.3, are presented in a format similar to that prescribed in the NRC's Radiological Assessment Branch Technical Position on Environmental Monitoring (Reference 1).

Table 4.4 presents the estimated direct dose from ISFSI operations as determined by TLD data shown in Table 4.1.

5.0 ANALYSIS OF ENVIRONMENTAL RESULTS 5.1 Sampling Program Deviations A sampling program deviation is defined as samples that are unobtainable due to hazardous conditions or to malfunction of sampling equipment. Such deviations do not compromise the program's effectiveness and in fact are considered insignificant with respect to what is normally anticipated for this Radiological Environmental Monitoring Program.

Two deviations of the sampling requirements occurred during this monitoring period. The first deviation is the TLD at location CY-54-IF was missing at the time of the 4 th quarter change-out; therefore, no data is available for that location for the 4 th quarter. The second deviation is an inadvertent exposure of the 4 th quarter TLDs by a calibration source at the RSCS home office. This event is documented in RSCS Condition Report # 13-17. This event does not affect the calculation of the 4 th quarter dose because both the control and monitoring location TLDs were exposed. It does, however, affect the exposure rate values.

This event has resulted in the 4 th quarter exposure rates to be between 1.12 and 1.71 times higher than the average, as determined from 2010 - 2012 3 rd quarter data, at each location.

5.2 Direct Radiation Pathway 5.2.1 Exposure Rates Direct radiation is continuously measured at 8 indicator locations surrounding the Haddam Neck ISFSI, along with 1 control location (Hurd Park Road) using thermoluminescent dosimeters (TLDs). These dosimeters are collected every calendar quarter for readout at the NVLAP certified dosimetry services vendor.

Review of the data in Tables 4.2 and 4.3 shows no significant difference between the indicator and control location exposure rates. Figures 4.1 through 4.9 show exposure rate trends of the monitoring locations since 2003. Review of Figures 4.1 through 4.9 shows no significant difference between the pre-operational and operational exposure rates at either the indicator or control locations. The data listed under each of the trend graphs show values for the result errors and discrimination levels. Note that these values are estimated and are shown only for information.

CY 2012 Annual REO Report Page 35 of 36

5.2.2 Direct Doses from ISFSI Operations The ODCM specifies that a cumulative dose estimate from direct radiation is required to be determined semi-annually. This dose estimate is the potential dose to any real member of the public that could use portions of the site or be present adjacent to the site for recreational activities throughout the year. The ODCM states that direct exposure above background can be estimated by subtracting the average TLD value of the control station from the indicator location measurements. As in previous years, the 2012 dose estimate assumes a total of 500 hours0.00579 days 0.139 hours 8.267196e-4 weeks 1.9025e-4 months occupancy for the dose calculation; of which 50 hours5.787037e-4 days 0.0139 hours 8.267196e-5 weeks 1.9025e-5 months are used in both the first and fourth quarters and 200 hours0.00231 days 0.0556 hours 3.306878e-4 weeks 7.61e-5 months are used in both the second and third quarters. The most likely location for exposure to a member of the public from the ISFSI is along the Connecticut or Salmon Rivers for boating and fishing; however, the time estimates are conservatively applied to all monitoring locations.

Table 4.4 presents the results of the dose calculations. The highest calculated dose is not along either river but at a location near the center of the site at Station ID number CY-55-1F. The maximum calculated annual dose at that location is 0.48 mrem. This value is only 2 percent of the 25 mrem per year limit.

The calculated annual dose to members of the public at the mouth of the Discharge Canal was 0.09 mrem. The calculated annual dose to members of the public at Route 149 near the mouth of the Salmon River was 0.00 mrem.

6.0 LAND USE CENSUS The most recent census remained in effect for 2012; therefore, no changes were made to the monitoring program.
