T ENVIRONMEitTAL MONITORING PROGRH4 ANNUAL REPORT:

PART A Facility:

Connecticut Yankee Atomic Power Company Facility Location:

Haddam Neck, Connecticut Reporting Period:

January 1, 1981 to December 31, 1981 Prepared by:

Joseph R. Smolen, Radiation Control Unit, Department of Environmental Protection This data is submitted pursuant to a Cooperative Agreement with the U.S. Nuclear Regulatory Commission for measuring concentrations of radioactivity and radiation levels in the environment around the Connecticut Yankee Atomic Power Company plant at Haddam Neck.

The principal objectives of the program are to (1) provide reasonable assurance that environmental measurements made by the Company under U.S. Nuclear Regulatory Commission requirements are valid, and (2) to independently monitor radiation levels in the environs of the nuclear power facility. Objective (2) is met by a State conducted program of sample collection and analysis: the analysis being performed by the State Health Services Laboratory.

Objective (1) is demonstrated by the substantial agreement between the State's results and the Company's (Licensee's) results on the split or duplicate samples.

The Cooperative Agreement requires that the State will notify the Commission on any observed unusual condition, level of radiation, or concentrations of radioactive material.

No notifications were necessary.

Millstone Pcint, Waterford, Connecticut l

Reporting Period:

January 1, 1981 to December 31, 1981 Prepared by:

Joseph R. Smolen, Radiation Control Unit, Department of Environmental Protection This data is submitted pursuant to a Cooperative Agreement with the U.S. Nuclear Regulatory Commission for measuring I

concentrations of radioactivity and radiation levels in the environment around the Millstone Nuclear Power Station I

at Millstone Point, Waterford. The principal objectives of the program are to (1) provide reasonable assurance that l

~

environmental measurements made by the licensee (Station Operator) under U.S. Nuclear Regulatory Commission require-ments are valid, and (2) to independently monitor radiation levels in the environs of the nuclear power facility.

Objective (2) is met by a State conducted program of sample collection and analysis: the analysis being performed by the State Health Services Laboratory.

Objective (1) is demonstrated by the substantial agreement between the State's results and the Licensee's results on split or duplicate samples.

1 The Cooperative Agreement requires that the State will notify the Commission on any observed unusual condition, level of radiation, or concentrations of radioactive material.

No notifications were necessary.

Smolen, Radiation Control Unit, Dept. of Environmental Protection Quality assurance data presented here is sumbitted pursuant to a Cooperative Agreement with the U.S. Nuclear Regulatory Commission (NRC) for measuring concentrations of radioactivity and radiation levels in the environment around NRC licensed nuclear power facilities in Connecticut:

the Connecticut Yankee, Haddam Neck Plant and the Millstone Nuclear Power station.

The principal objectives of the agreement are to (1) provide reasonable assurance that environmental measurements made by the licensed (facility operator) under NRC requirements are valid, and (2) to independently monitor radiation levels in the environs of the nuclear power facilities.

Part A and Part B of this Annual. Report describe the work performed and present the results of comparative measurements on split or duplicate environmental samples.

This part of the Annual Report, Part C, presents quality assurance data developed by the Connecticut Health Ser'. ices Laboratory through its participation in the Environmental Radioactivity Laboratory Intercomparison Studies Program conducted by the U.S. Environmental Protection Agency, Envirennental Monitoring and Support Laboratory at Las Vegas, Nevada.
