2880099940 SEMI-ANNUAL EPPLUENT RELEASE REPORT JANUARY 1, TO JUNL 30, 1988

1. MTRODUCTION In accordance with the Unique Reporting Requirementa of Technical Specification 6~.9.2.h(2) applicable during the reporting period,'this report summarizes the Effluent Release Data for Peach Bottom Atomic Power Station Units 2 and 3 for the period January 1 through June 30, 1988. The notations E and E-are used to denote positive and negative exponents to the base 10.

The release of radioactive materials during che reporting period was within the Technical Specification limits. There were changes made to the Offsite Doce Calculation Manual (ODCM) during the reporting period.

A copy of the Offsite Calculation Manual is attached to this report.

There were no known unplanned releases of liquid radioactive material.

A special report discussing the inoperability of the Main Stack Sample Flow Monitor is included in the ATTACHMENT B section of this report.

Iodine was not present from either the roof vents or main stack in section labeled Gaseous Effluents (Table 1A). Therefore, the Critical Organ Dose for iodines in mRea was zero. In accordance with the current revision of the Offsite Dose Calculation Manual (ODCM) attached to this report, the Critical Organ Dose was calculated using the particulates with half-lives greater than 8 days. These calculations are incorporated into the ATTACHMENT B section of the report.

In section labeled Liquid Effluents (Table 2B) the Phosphorus-32 reported value is less than the lower <

limit of detection. The half-life of Phosphorus-32 has l been exceeded by a factor of eight half-lives, j therefore, Phosphorus-32 is reported as zero for this repcrting period, in general, any isotope with half- I lives greater than eight shall be reported as zero.

SUMMARY

OF UNPLANNED RELEASES i l

1. Inoperable Main Stack Sample Flow Monitor On February 9, 1988, the Main Stack sample flow rate monitor (PT-7341) could not be calibrated during a surveillance test, thus the monitor was determined to be inoperable. Technical Specification 4.8.C.4.e requires that if inoperable radiation monitors cannot be corrected within 30 days, an explanation of why the inoperability was not corrected will be reported in the next Semi-annual Radioactive Effluent Releases Report A replacement monitor was ordered; however, the manufacturer could not supply the same model. In addition, the manufacturer could not deliver a replacement until late May, 1988. On March 18, 1988, a calibration check was successfully performed on a redundant in-line Flow Indicating Transmitter (FIT-6509), which is being used to temporari)y perform the same function as FT-7341. Meanwhile a site modification is currently being designed to install the new monitor, This modification is expected to be installed by October 10, 1988.
2. Calculations For Critical Oroan Dose Usino Particulates With Half-Lives Greater Than 8 Days The following doses were calculated using particulates identified during the first and second quarter reporting period of 1988; PARTICULATE CRITICAL ORGAN DOSE, LIVER, (MREM)

Quarter 1 Quarter 2 Sr-89 6.40 E-8 1.18 E-7 Sr-90 2.97 E-6 5.03 E-6 Co-60 1.03 E-8 8.50 E-8 Zn-65 2.07 E-6 3.05 E-5 Total 5.11 E-6 3.57 E-5 The percentage of Technical Specification for the Critical Organ (liver) for the first quarter is 3.41 E-5, second quarter is 2.38 E-4.
