INTRODUCTION SALEM NUCLEAR GENERATING STATION 50-272 UNIT NO. 1 RADIOACTIVE EFFLUENT.RELEASE REPORT DECEMBER 11, 1976 -

DECEMBER 31, 1976 The Salem Nuclear Generating Station Unit 1 went critical on December 11, 1976.

During most of December the plant was

~ operating at less than 10% power.

As a result of this the radiological impact of station operation was minimal.

With the exception of several batch releases all sampling resulted in activity below the Lower Limit of Detection (LLD).

All symbols used are as stated in Section 2.3.3 of the Environmental Technical Specifications.

The release limits for the Salem Nuclear Generating Station are not fixed numbers, but depend upon the radio-active isotopes present in the effluent.

Part D. Liquid Effluents The regulatory limits for liquids are governed by 10CFR20, Appendix B, Table II Column 2.

In addition, the following limits apply:_

At no time shall any radwaste tank contain more than 10 Ci of activity.

Noble gases and tritium are excluded from this limit.

The cumulative release of radioactive effluents, excluding tritium and dissolved gases, shall be less than 10 ci:' in a calendar quarter for each unit.

The cumulative release of radioactive effluents, excluding tritium and dissolved gases, shall be less than 20 Ci in any twelve consecu-tive months.

Item A4 Measurements and Approximation of Total Radioactivity

1.

Liquid effluents are monitored in accordance with Table 2.3-3 of the Salem Nuclear Generating Station Environmental Technical Specifications (ETS).

During the period of record all waste from the chemical drain tank and the* la:µndry and hot shower tanks were routed to the waste monitor holdup tanks.

The tanks were then recirculated in order to produce uniform mixing and a sample was extracted and analyzed.

2.

Gaseous effluent streams are monitored in accordance with Table 2.3-4 of the Salem Station ETS.

The station's plant vent is the final release point of all planned gaseous effluents.

This'location is monitored continuously for noble gases by 4 Geiger-Mueller tubes and is sampled con-tinuously for iodine and particulates with a charcoal cartridge and Cesco filter paper. connected in series to a high volume air sampler.

The filter apd charcoal are changed weekly and counted in the laboratory.

$ampling is also performed on all gas decay tanks released into the environs.

The result of these analysis is used as the basis for the cumulative release of gaseous effluent into the environment.

Tritium samples were* taken by bubbling gas through water and then counting the tritiated water.

3.

Overall error for gaseous releases estimated to be 10 percent This error is a result of gas decay tank sampling and measure-ment only.

All liquid measurement proved to be below the lower limit of detection.

Therefore, error estimates are not provided

Item AS Batch Releases

.Batch releases of gaseous and liquid effluent are provided in Tables. 4A -

E RADIOLOGICAL IMPACT ON MAN The calculated doses in this section pertain to those received in unrestricted areas.

LIQUID PATHWAYS Doses to individuals in the population resulting from liquid pathways will be provided at a later date, as sample analysis has not been fully completed.

These doses will be relatively insignificant as the only liquid pathway is the ingestion of seafood.

The low-level liquid releases coupled with *the small seafood harvest during the month of December will result in a minimal impact.

AIR PATHWAY The individual and population doses resulting from the release of radioiodines and particulates will be inconsequential as there was no iodine or particulates present in any of the samples taken for this period of record.

There were only two isotopes identified as a result of gaseous samples taken during this reporting period.

These isotopes, Xe-133 and H-3, were identified as a result of sample analysis.

The resulting maximum, unrestricted area, whole body and skin doses were *calculated to be l.79E-9 mrem and 5.08E-9 mrem respectfully.

The highest dose to any organ dose from radioactive iodines and particulates was not calculated due to their absence in sample analysis.

The calculated population whole body dose was J.OlE-11 man-rem.

The average total body dose to the population within 50 miles of the site was 6,20E-12 mrem.

The doses were calculated using methods described in Regulatory Guide 1.109.

DIRECT RADIATION The dir.ect radiation, resulting from station operation, is considered to be zerb due to the short operating period and low-level operations for this period of record.

F METEOROLOGICAL DATA Cumulative joint wind frequency distributions by atmospheric stability class are provided for the period of station operation (December 11 -

December 31, 1976) as Table 5.

Table 6 provides joint wind frequency distiibutions for the hours of Gas Decay Tank releases (batch releases) for this same period.

Only data for those hours since initial criticality is provided as data covering the entire third and fourth quarters would result in misleading dispersion estimates.
