! A. f2Ef.0SI ,

l The purpose of this procedure is to delineate the methods of transferring l 11guld waste from the High Radiation Sampling System (HRSS) Weste Tank and j Waste Sump to either unit's waste collector tank or drywell equipment sump and of transferring gaseous wastes from the HRSS Waste Gas Hold-up Tank l during normal and post-accident conditions.

C. PRIEICUISH IS

1. During Post-Accident Conditions CHLY, VERI!T that the HRSS Room Air Conditioning Unit la turned CTT.

j 2. In a Post-Accident condition only, the HRSS Waste Tank must be

) recirculated and sampled prior to transferring the liquid weste to ,

another tank or sump in accordance with the following at the HRSS Valve Control Panel, OPLC9J: (

l l

3. OPEN OPS-012, HRSS WASTE TK OUT VLV, and VERITY that the indication shows CPEN.

l

b. START the HRSS Waste Pwnp A or B, OPS-01PA(B), and VER1!T that the pump is running by the light indication. l

c. CPDI OPS-016, HRSS WASTE TK SAMPLE VLV, and VERITY that the l

Indication shown CPDI.

d. ALLCW the HRSS Waste Tank to recirculate for a minimum of five I (5) minutes. l l

3. ESTABLISH communications with the Unit Nuclear Station Operator (NSO)

! and inform him of the sample evolution to be performed.

4. Prior to transferring wastes, the Radwaste Toreman should be contacted to determine where to transfer the waste and the amount to ,

transfer. '

1. A Regulatory Guide 1.3 or 1.4 release of fission products implies I extremely high levels of radioactivity. Dose rates may be high enough to prevent entry into many areas of the plant that are normally habitable. Radiation Protection Supervision should be I contacted prior to entry into any area when such a release of fission products is suspected.

. Wear radiation dosimetry, protective clothing and respiratory

.I protection as recommended by Radiation Protection Supervision.

3. Appropriate survey instruments should be available for monitoring during this procedure.

4. The HRSS Waste Room and associated piping runs should be secured to personnel during the perfornance of this procedure and not re-entered I E.

prior to contacting Radiation Protection.

1. In a Post-Accident condition only, a sa.mple of the HRSS Waste Tank must be analysed prior to sending waste fluid to the Waste Collector Tonk of either unit. The source inventory of the liquid in the HRSS I Waste Tank must be made since each Waste Collector Tank must be kept below 30.000 curies and the Chemical Waste Collector Tank must be kept below 100,000 curies.

2. This procedure, though intended for use under post-accident conditions can be used during normal operating conditions during which the precautions listed may or may not apply. However, normal I r.

routine sampling precautions should be observed, FROCEDUf,

1. At the HRSS Valve Control Panel, CPLC9J. PLACE the UNIT 1(2) POWER switch in the OPERATE position.

2. To transfer the liquid waste from the HRSS Waste Sump to the Waste Collector Tank. PROCEED to Step r.4. To transfer gaseous vastes frem the HRSS waste Gas Hold-up Tank to the Suppression chamber, PROCEED to Step r.5.

3. To transfer the 11guld waste from the HRSS Waste Tank to either the Waste Collector Tank or the Drywell Equipment Drain Sump, PROCEED in I accordance with the fo}1owing at the Valve Control Panel, SPLC9J

a. OPEN the HRSS WASTE TT, CUT VLV, OPS 012, and VERITY that the I indication shows CPEN.
