SAN ONOFRE NUCLEAR GENERATING STATION CHEMICAL PROCEDURE S 41-111-5.2.1 UNIT I JUL 01 8 REVISION 0 PAGE 6.0 PROCEDURE (Continued) 6.3 Liquid Radwaste Release Composite Sampler The liquid radwaste release composite sampler should be in servicepon all Holdupjank and Monitor Tank releases greater than 900 gallons. The composite sampler draws a small volume of sample for each 300 gallons of liquid released. Setting up the composite sampler for sampling a release is normally done by operations. Proceed as follows for the operation of the compositor.

6.3.1 Representative Sampling

.1 Open the flow integrator and set the selector valve for the 0-10 gpm or 0-100 gpm flow positions, depending on the orifice selected for use.

.2 Immediately after a release flow is established, fully open the metering valve. Depress (and hold) the "Purge" button on the Radwaste Control Board and flush the sample line to waste for one minute.

.3 Adjust the metering valve and agastat settings as spe:ified on the radioacative liquid release permit.

.4 Ootair a two liter liquid sample container with a label.

Re:ord release nimber and source identification (e.g., E Holdup or N Monitor Tank) on the sa!ple container label.

Designate type of sample as "Cc-.posite".

.5 Place the sample container under the sampling location.

.6 After completion of sampling transfer "composite" sample to radiochemistry laboratory for analysis for gamma emitters, gross alpha and trituim.

.7 Notify the Chemical Foreman or the Watch Engineer that sampling has been completed.

.8 Save sample for inclusion in monthly composite sample as per Section 6.12.

6.4 Liquid Radwaste Effluent This sample point represents the final effluer: Df a heldup tank or monitor tank release. It is downstream of the ga. sripver and discharge filter. The liquid radwaste effluent sarling location is next to the gate to the gas stripper and flash tank.

Sampling of liquid effluent is done after a release has been initiated. The sampling requirements of Ref. 2.4 dictate when it is necessary to obtain three samples, one each at the start, midpoint, and end of the release progres-.

SAN ONOFRE NUCLEAR GENERATING STATION CHEMICAL PROCEDURE S01-111-5.2.1 UNIT I REVISION 0 PAGE 5 JUL 0 11982 6.0 PROCEDURE (Continued) 6.4.1 Representative Sampling

.1 Check the circular graph on the Radwaste Control

Board (centrally located -in

-lower radwaste) to verify liquid radwaste effluent flow.

.2 Open sample valve and purge sample line at -1 liter/min flow for a minimum of five minutes.

.3 Collect a 250 ml sample in a 250 ml sample container. Close sample valve.

.4 Label the sample as appropriate (whether taken at "start", "mid", or near the "end" of the release in progress), and identify source, time and date.

.5 Send the sample to the radiochemistry laboratory for analysis for gamma emitters.

.6 Save sample for inclusion in release composite should the release composite sampler not be in service.

6.5 Steam Gererator Blowdown 6.5.1 Steam generator blowdown samples are normally ccllected for activity analysis during operation under three conditions:

.1 Feedwater 3H > 1.0 x 10 - 4 ii/cc.

.2 Unit Load Reduction.

Cesium hideout returns to solution from sludge deposits.

.3 Steam Generator Sludge Blowdown.

Cobalt isotopes present in the sludge are discharged during the periodic sludge blowdown procedure. ORMS Channel 1216 may alarm due to high activity during these periods.

.4 Sampling and analysis of steam generator blowdown should be carried out under the above conditions as indicated in Attachment 8.1.

.5 Record data concerning these releases on Attachmen:

8.2.

.6 Prepare a Radioactive Release Permit for each composite sample as required.

-- on-exchanger(s)-in -service-during holdup tank processing or liquid radwaste discharge. Normally, inlet and outlet samples of each ion exchanger in service are required.

.1 Check the circular chart recorder (R-10) on the radwaste control board centrally located in lower radwaste. This chart records all processing and release flow data. Verify that flow for the process to be sampled is-stable and has been in progress for a minimum of 15 minutes.

.2' The inlet and outlet sample lines for the process ion exchangers A, B, C and D are located in the valving corridor east of the base of the stairway descending into lower radwaste.

.3 Trace the sample line fror the root valve to verify that the correct sample is collected.

Open the sample valve and purge the line at -

I liter per minute for a minimum of five minutes.

NDTE: If sampling the outlet of an ion exchanger flowinc to an empty holdup tank, the sample may be under negative pressure. Check the pressure indicator for the appropriate ion exchanger (PI1 191, PI 192, PI 193, PI 194). If a negative pressure is indicated, contact the control operator to have the ion exchanger outlet valve throttled.

6.7 Oily Waste Sump Effluent 6.7.1 This sample point represents the composite of the reheater sump and various other turbine plant flow paths. It is normally sampled on a weekly basis unless activity is suspected or found to be present. In the latter case, periodic sampling may be initiated as necessary to evaluate the release. (See schedule in Attachment 8.1).

.1 The oily waste sump sample point is located just outside the vital area fence on the west side of the condensate storage tank.

.2 Open the sample valve and purge the line at ~ four liters per minute for at least one minute.

.3 Collect samples as required. A four liter Marinelli sample is normally required for counting on the (GeLi) detector system.
