i APPENDIX A NOTICE OF VIOLATION GPU Nuclear Corporation Docket No. 50-289 Three Mile Island Nuclear Generating Station Unit 1 License No. DPR-50 As of result of the reactive inspection conducted on August 15-16, 1989, and in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2 Appendix C (Enforcement Policy) (1989),

thefollowingviolationwasidentifled.

The Three Mile Island Nuclear Generating Station-Unit 1 Technical Specifications, Section 4.22.2.1.2 states, "The dose rate of radioactive materials, other than noble gaser, in gaseous effluents shall be determined to be within the limits of Specification 3.22.2.1.b in accordance with methods and procedures of the ODCM by obtaining representative samples and performing analyses in accordance with the sampling and analysis program, specified in Table 4.22-2. "

Contrary to the above requirement, the airborne radioiodine collection cartridge samples intended to measure effluent radioactive iodines from the condenser vent stack continuous iodine sampler were not representative of releases from this pathway during the interval from October,1986 to June, 1989. As a result of iodine breakthrough, the cartridge results underestimated the amount of iodine releases. Because of improper quantification of iodine releases, required offsite dose commitments from October, 1986 to June, 1989 were underestimated.

This is a Severity Level IV violation (Supplement IV).

Pursuant to the provisions of 10 CFR 2.201, GPU Nuclear Corporation is hereby required to submit to this office within thirty days of the date of the letter which transmitted this Notice, a written statement or explanation in reply, including: ( ) the corrective steps which have been taken and the results achieved; (2 corrective steps which will be taken to avoid further violation; and (3) the ate when full compliance will be achieved. Where good cause is shown, consideration will be given to extending this response time.
