APPENDIX A 1

Radioactive Liquid Effluent Monitoring Instrumentation J

Requirement: Radioactive liquid effluent monitoring instrumentation channels are required to be operable in accordance with Technical l

Specification 3.3.3.6.

With less than the minimum number of channels operable and reasonable efforts to return the instruc..ent(s) to operable status within 30 days being unsuccessful. Technical Specification 3.3.6.b requires an explanation for the delay in correcting the inoperability in the next Semiannual Effluent Release Report.

Response

The flow rate measuring device for the steam generator blowdown tank effluent (Table 3.3-8) was installed during this reporting period, but has not yet been calibrated. ACTION Statement 17 of Table 3.3-8 is still in effect until the flow rate measuring device for the steam generator blowdown tank effluent is calibrated, which is expected during the next reporting period.

Response

There was one licensee initiated amendment to the Process Control Program during this reporting period.

The following April 23, 1987 changes were made to the YNPS Process Control Program:

Provided the option of drilling of cement solidified in a.

55-gallon drums to allow for inspection of selected drums for dryness, and b.

Add to and modify Appendix B. " Station Procedures Which Implement the PCP."

The above changes did not reduce the overall conformance of the solidified waste product to existing criteria for solid wastes.

Measurements and Approximations of Total Radioactivity a.

Noble Gases

" Continuous discharges" are determined by indirect measurement.

Primary gas samples are taken periodically and analyzed.

It is

. assumed that in primary to secondary leakage all gases are ejected through the air ejector.

In primary coolant charging pump leakage all gases are ejected to the primary vent stack either during flashing or liquid waste processing. " Batch discharges" are determined by direct measurement.

Errors associated with these measurements are estimated to be +55 percent.

b.

Iodines Iodines are continuously monitored by drawing a sample from the primary vent stack through a particulate filter and charcoal cartridge. The filter and charcoal cartridge are removed and I-2 4824R/20.124

analyzed weekly. The errors associated with these measurements are estimated to be 25 percent.

c.

Particulate The particulate filter described in (b) above is analyzed weekly.

The errors associated with the determination of particulate effluents

}

are estimated to be 230 percent.

d.

Liquid Effluents Liquid effluents are determined by direct measurement.

In line composite samples are analyzed for strontium - 89, strontium - 90, gross alpha activity and carbon - 14.

There is no compositing of samples for tritium or dissolved fission gas analysis. For continuous discharges composite samples are used for gamma isotopic analysis.

A gamma isotopic analysis is performed on a representative sample for each batch release using the Marinelli Beaker geometry.

The errors associated with thece measurements are as follows:

fission and activation products, 320 percent; tritium, i10 percent; dissolved fission gases, 20 percent; alpha activity, 135 percent.
