1 10 2.11 Lower Limit of Detection (LLD)

The LLD (an a priori limit) is defir?d as the smallest concentration of radioactive material in a sample that will yield a not count, above system background, that will be detected with 95% probability, and only a 5% probsbility of falsely concluding that a blank observation represents a "real" signal.

4 2.12 Dose to MEMBERS OF THE PUBLIC On Site MEMBERS OF THE PUBLIC due to their activities within the SITE BOUNDARY may be subject to direct radiation exposure at extremely low levels. MEMBERS OF THE PUBLIC are permitted to skirt the site boundary (1500 meters out) on Farm to Market Highway #521 for about five miles. MEMBERS OF THE PUBLIC are also allowed access to the visitor's center which is within the site boundary about 1600 meters from either Unit 1 or Unit 2.

Appendix A is a summary of the dose rates measured by TLD's placed within the Protected Area fence around the Units (about 133 meters from either unit). The average dose rate measured by these TLD's was about 11.8 mrem / quarter. The average dose rate measured in the vicinity of STPEGS by the Radiological Environmental Monitoring O. Program was about 15.4 mrem in 1986, the year before plant operation began. Hence the average dose rate near the plant was lower than the pre-operational dose rate with the exception of one measurement station (location 1-03 of the accompanying figure). This station is midway between the security fence surrounding Unit 1 and a radioactive waste loading area. The dose rate in this area is about 14.6 mrem / quarter. Normal visits of a few hours to the visitor's center, tours of the site (typically outside the Protected Area fence), or daily trips past the site on FM #521 should have resulted in an annual maximum dose to a MEMBER OF THE PUBLIC of less than 1 mrem / year. The following example calculations support this assertion.

(,/ 3.1 Radioactive Waste Treatment System Design Modification Description (ref. Technical Specifications 6.15)

A Unit 1 liquid radioactive waste treatment system design modification was completed during this reporting period (Appendix B). No changes were made to Unit I solid or gaseous radioactive waste treatment systems or to Unit 2 solid, liquid or gaseous radioactive waste treatment systems.

3.2 Inoperable Effluent Monitoring Instrumentation Explanation (ref.

Technical Specifications 6.9.1.4)

Condenser Vacuum Pump Wide Range Gas Monitors NIRA-RT-8027 and N2RA-RT-8027 were removed from service on November 1, 1988 at 0100.

Since the problems with the monitors were not repaired within 30 days, the following is provided as an explanation.

s_-

) J The Condenser Vacuum Pump Wide Range Gas Monitors N1RA-RT-8027 and i N2RA-RT-8027 have similar problems with the process fluid stream. '

In both cases, the actual process flowrate is less than the designed process flowrate and the fluid is humid air instead of a mixture of steam and air as expected. Plant Hodifications were written to i redesign the output of the condenser to flow to the Unit Vent. This ]

solution is expected to relieve N1RA-hf-8027 and N2RA-RT-8027 of the '

burden of being isokinetically sampling monitors and will eliminate the need for measurement of wet process and wet sample flows. Plant- I Modification 89-066 installation has been scheduled for the second refueling outage of Unit 1. Operation is contingent upon implementation of the change to Technical Specification 3.3.3.11. '

The Unit 2 modification (89-067) will follow in line with Unit 1 once it has been installed. !

3.3 Gas Storage Tank Curie Limit Violation Description (ref. Technical Specifications 6.9.1.4)

-RADWASTE TREATMENT

SYSTEM DESIGN MODIFICATION

1. A summary of the evaluation that led to the determination that the change could be made in accordance with 10CFR50.59, A 10CFR50.59 Determination Review Form was completed by Support Engineering. It was determined that there was not an Unreviewed Safety Question.

2. Sufficient detailed information to totally support the reason for the change without benefit of additional or supplemental information:

The laundry and hot shower tank (LHST), condensate polishing regenerative-waste collection tank (CPRWCT) and associated. piping in the Liquid Waste Processing System have undergone several design changes during construction resulting in the LHST being seldom used and laundry and dry

- < cleaning drains,being routed to CPRWCT. .The intent of the original plant design was to have laundry and dry cleaning drains routed to the LHST.

This modification rerouted the laundry and dry cleaning drains in Unit 1-to the LHST for the following reasons:

a. LHST has a usable volwne of 9300 gallons. This modification added much needed volume-to the-LWPS. LHST may be discharged directly to the reservoir and eliminates need for use of waste, monitor tanksspace.

-h-v This aids Chemical Operations in processing of radioactive Liquid Waste,

b. Chemical Operations processes CPRWCT several' times weekly. Lint from the laundry along with other impurities caused strainer clogging resulting in several change outs in order to achieve required recirculation time prior to sampling.

c. 'The CPRWCT receives floor drains during the floor drain tank processing, and primary lab drains. Processing by evaporation may be required to adequately dispose of this waste. The detergent from the laundry drains complicates processing by evaporation due to foaming.

3. A detailed description of the equipment, components, and processes involved and the interfaces with other plant systems:

This modification affects a portion of the laundry and dry-cleaning drain piping (4" dia.) which is connected to the chemical water header. The Laundry and dry cleaning drain connected to the chemical waste header was disconnected and the chemical waste header branch was capped. The' Laundry and dry cleaning drain was then routed to existing laundry and hot shower drain header. This allows draining into the laundry and hot shower tank.

4. An evaluation of the change, which shows the predicted release of radioactive materials in liquid and gaseous effluents and/or quantity of solid waste that differ for those previously predicted in the License

() Application and Amendments:

This drain'.was rerouted and connected to the laundry and hot' shower tank. ,

This modification dcas not change the amount of liquid and gaseous effluents, nor quantity of solid waste predicted in'the License Application and Amendments.

5. An evaluation of the change, which shows the expected maximum exposure to individuals in the UNRESTRICTED AREA and to the general population that differ from those previously estimated in the License Application and ,

Amendments:

This modification affects the laundry and dry cleaning drain connected to the condensato polishing regenerative waste collection tank. This drain was rerouted and connected to the laundry and hot shower tank. This ;

modification will not result in a change to expected maximum exposures to !

'l -- individuals in the unrestricted area and to the general population as-previously estimated in the License Application and Amendments. '

6. A comparison of the predicted releases of radioactive materials, in liquid and gaseous effluents and solid waste, to the actual releases for the period prior to when the changes are to be made This modification affects a portion of the laundry and dry cleaning drain

(T connected to the condensate polishing regenerative waste collection tank.

L \_) The drain was rerouted and connected to the laundry and hot shower tank, ,

This modification does not change the amount of liquid and gaseous [

effluents, and solid waste. The predicted releases of radioactive

' materials, in 11guld and gaseous effluents and solid waste should oe the same as the actual re19ases for the period prior to when the change was ;

made.

7. An estimate of the exposure to plant personnel as a result of the change:

This modification affects the laundry and dry cleaning drain, which was connected to the condensate polishing regenerative waste collection tank.

This drain was rerouted and connected to the laundry and hot shower tank.

This change will potentially result in decreased exposure to plant

personnel. Use of laundry and hot shower tank for processing the laundry and dry cleaning drains will reduce the handling of contaminated strainers I,

at the CPRWCT due to lint, tape, and impurities from the laundry thereby reducing exposure.

I 8.- Documentation of the fact that the change was reviewed and approved by the Plant Operations Review Committee (PORC)

I A 10CFR50.59 Evaluation Form was completed by Support Engineering. It was i determined that there were no Unreviewed Safety Questions and a PORC

)l Review was not required for this design change.
