1. Regulatory Limits

a. Gaseous Effluents

1) The air dose due to noble gases released in gaseous ef fluents, from each reactor unit, from the site shall be limited to the following:

a) During any calendar quarter: Less than or equal to 5 mrad for gamma radiation and less than or equal to 10 mrad for beta radiation, and b) During any calendar year: Less than or equal to 10 mrad for gamma radiation and less than or equal to 20 mrad for beta radiation.

2) The dose to an individual from radiolodines and radioactive materials in particulate form, and radionuclides, other than noblo gases, with half-lives greater than eight days in gaseous effluents released, from each reactor unit, from the site shall be limited to the following:

a) During any calendar quarter: Less than or equal to 7.5 mRems to any organ, and b) During any calendar year: Less than or equal to 15 mRems to any organ,

b. Liquid Effluents

1) The dose or dose commitment to an individual from radioactive materials in liquid effluents released, from each reactor unit, from the site shall be limited:

a) During any calendar quarter to less than or equal to 1.5 mrem to the total body and to less than or equal to 5 mrem to any organ, and b) During any calendar year to less than or equal to 3 mrem to the total body and to less than or equal to 10 mrem to any organ,

c. Total Dose

1) The dose or dose commitment to any member of the public, due to releases or radioactivity and radiation, from uranium fuel cycle sources shall be lim ted to less than or equal to 25 mrem to the body or any organ (except the thyroid, which shall be limited to less than or equal to 75 mrem) over 12 l consecutive months, l

1) The dose rate due to radioactive materials released in gaseous effluents from the site shall be limited to the following:

a) For noble gases: Less than or equal to 500 mrem / year to '

the total body and less than or equal to 3000 mrem / year to the skin, and b) For all radioiodines and for all radioactive materials in particulate form, and radionuclides, other than noble gases, with half-lives greater than eight days: Less than or equal to 1500 mrem / year to any organ via the inhalation pathway.

b. Liquid Effluents

1) The concentration of radioactive material released form the site shall be limited to the concentrations specified in 10 CFR Part 20, Appendix B, Table II, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to the following:

Supplemental Information (continued)

4) All release types as listed in 1 and 2 above, at the vent stack and as listed in 3 above, at the Standby Gas Treatment System whenever there is a flow, are continuously sampled by charcoal, particulate and composite samples which are analyzed for iodines, principal gamma emitters, gross alpha, Sr-89 and Sr-90. Noble gases, gross beta and gamma are continuously monitored by noble gas monitors for the vent stack and the-standby gas treatment system.

b. Liquid Effluents

1) Batch waste release tanks are sampled each batch for principal gamma emitters, I-131, dissolved and entrained noble gases, H-3, gross alpha, Sr-89, Sr-90 and Fe-55,

2) continuous releases are sampled continuously in proportion to the rate of flow of the effluent stream and by grab sample.

Samples are analyzed for principal gamma - emitters, I-131, dissolved and entrained noble gases, H-3, gross alpha, Sr-89, Sr-90 and Fe-55.

STATION VENT STACK PARTICULATE SAMPLE LOST DURING SHIPMENT I

Description and cause of Event: I The July 1993 station vent stack particulate samples were shipped from i LaSalle Station in a five gallon bucket via Yellow Freight Lines to -)

'TMA/NORCAL in California for analysis in the vendor's laboratory. The i bucket never made it to the vendor. '

The Yellow Freight representative at Marseilles ran a tracer on the shipment for us. Yellow Freight was able to trace the bucket from LaSalle Station to Marseilles, and from Marseilles to the Chicago dock. The Chicago dock paperwork shows it loaded on the truck bound for Tracy California. However, Tracy California shows it as a shortage, that is, their paperwork shows it wasn't on the truck when it got there. Yellow Freight's Marseilles Representative said since it was shipped so long ago (August 24, 1993) they didn't think it was very likely they would be able to locate it, if it was going to turn up it would have by now. They considered the bucket lost.

Although these samples are sent out for analysis every month they are usually not a rad shipment and are able to be shipped together. This month the SVS particulate could not be unconditionally released and had to be shipped as radioactive material. These samples had not been shipped in this manner for the past 18 months.

Although there is a surveillance item on the 25th of each month to verify that the vendor has received the sample the station did not realize this sample had been lost until November 1, 1993. Usually this sample (SVS particulate) is shipped with the Lake Blowdown sample and their is one surveillance for the combined sample shipment. This time the SVS particulate could not be released as unconditional and was sent as a second shipment (radioactive material shipment). On September 24, 1993 TMA/NORCAL acknowledged receipt of the shipment thinking it was the July sample not realizing they had just received the August sample. On November 1,1993 the station Chemistry Department received the July sample analysis from TMA/NORCAL and recognized the results were missing for the SVS particulate sample. The length of time between the shipment date and the date the tracer was placed on the shipment added to the difficulty in tracing the bucket.

The significance of the lost bucket / sample is the failure of LaSalle Station to meet section 12.4.1.B.2 and Table 12.4.1-1 item D of the Station's ODCM. The consequence of the lost bucket / sample is the ODCM requires the station to include this information in the next semi-annual effluent report. The report is required to be completed 60 days af ter the end of the reporting period, in this case December 31, 1993 is the end of the reporting period.

l Corrective Actions:

1. Station Chemistry to submit a separate surveillance (G-SURV) for each sample. Each sample will be tracked separately in the future.

2. Rad Protection will include the fact that the required ODCM monthly SVS particulate sample was ndssed and include details of this event in the next Semi-Annual Effluent Report.
