INTRODUCTION In accordance with the Unique Reporting Requirements 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 July 1 through December 31, 1986.

The notations E and E-are used to denote positive and negative exponents to the base 10 respectively.

The release of radioactive materials during the reporting period was within the Technical Specification limits.

There were no changes to the Off-Site Dose Calculation Manual (ODCM) during the reporting period.

An unplanned release of liquid radioactive material from the Pressure Service Water (HPSW) occurred on September 22, 1986.

This is discussed in the attachment section of the report.

This revised report is being submitted to reflect corrections to several errors which were previously reported.

The following changes have been made:

o Page 1 Total Release 8.98 E3 (3rd Quarter) o Page 2 Xenon-138 4.02 E2 (3rd Quarter)

Total 8.71 E3 (3rd Quarter)

Iodine-133 3.28 E-3 (4th Quarter)

Iodine-135 1.22 E-2 (3rd Quarter)

Total 3.11 E-2 (3rd Quarter) 1.20 E-2 (4th Quarter) o Page 3 Yttrium-91M 3.13 E-2 (3rd Quarter)

Totals 1.43 E-1 (3rd Quarter) o Page 4 Xenon-133M 8.30 E0 (3rd Quarter)

Total 2.66 E2 (3rd Quarter)

Lanthanum-140 3.87 E-4 (3rd Quarter) o Page 5 Totals 3.52 E-2 (3rd Quarter)

In addition, this revised report includes an unplanned release of liquid radioactive material from the Raw Water Sump, which was inadvertently omitted from the previous report.

Attachment B has been revised to reflect this addition.

A bar has been placed in the margin adjacent to the corrected information.

ATTACHMENT B Unplanned Liquid Release Via 3B High Pressure Service Water An unplanned 11guld release of radioactive High Pressure Service Water occurred on September 22, 1986.

The release was detected by a series of peaks on the High Pressure Service Water radiation monitor; however, the series of spikes on the strip chart of this event could indicate possible radiation transients at the monitor.

The High Pressure Service Water was not operating at the time.

No grab sample was obtained during the 30 minute duration of the event.

Calculated doses are based on the methodology presented in the Offsite Dose Calculation Manual, assuming a release rate of 3 gpm (monitor sample flow rate) and average release concentrations based on the radiation monitor's strip chart.

The whole body dose from this release was calculated at 7.91E-6 mrem, and the bone dose was calculated at 8.97E-6 mrem.

Unplanned Liquid Release Via the Raw Water Sump An unplanned liquid release of radioactive water through the Raw Water Sump occurred on November 13, 1986, caused by a 55 gallon drum which was routinely released through the sump.

The release was discovered following a review of drum sheets which indicated that the drum contained radioactive water.

A grab sample was obtained.

Calculated doses are based on the methodology presented in the Offsite Dose Calculation Manual, assuming a release rate of 10 gpm and release concentrations based on an actual grab sample.

The whole body dose from this release was calculated at 5.16 E-7 mrem, and the bone dose was calculated at 3.92 E-7 mrem. - _ _ _ _ _ _ _ _ _ _ - _ _ _ _
