REQUEST FOR ADDITIONAL INFORMATION

' Application Date July 21,1999 Siemens Power Corporation Docket 70-143 GeneralInformation I 1. In the license application, replacement tanks for Lagoon 1 and Lagoon 5B were not

~ discussed.~ Describe what the future intentions are for Lagoons 1 and 58.

l

2. Provide an updated version of Figures ll-10.28, ll-10.29, and ll-10.29a.

Decommissioning

3. Does the addition to the Ammonium Recovery Facility affect the Decommissioning Plan as discussed in Chapter 7 of the license application?

Process Safety Information

4. Describe the procedure that will be used to add chemicals to the new process waste storage tanks.

5. Provide the materials of construction and tank dimensions for each new tank. Describe any incompatible material or chemicals in the new process waste storage area.

6. Provide a detailed schematic drawing of the new process waste storage area piping

" which includes: pumps, sampling ports, and leak detection devices. Will sump pumps be included in the new design?

7. What reactions, if any, could take place in the new process waste storage area?

8. What chemicals will be used to regenerate ion exchange resin that is stored in Tank 1

. (lon Exchange Regeneration Tank)? Provide data which shows that regeneration chemicals are compatible with the Miscellaneous Uranium Recovery System (MURS) process.

9. Provide' experimental results or calculations demonstrating that chemicals used for regenerating the ion exchange columns are compatible with the resin and will not produce hazardous or unfavorable reactions.. The concem is that some IX resins have pressurized storage drums from the reaction between the resin and chemicals.

10. How will ammonia releases be prevented in the new process waste storage area?

11. Will the new facility contain personal protective equipment (PPE) , if not, what is the closest building in proximity to the new process waste storage area that contains PPE7

i- ]

i 2-Ooeratina Procedures i12. How will wastewater flow initially be redirected from lagoons to the new waste storage tanks during start-up? How will the lagoons be drained, what are SPC's plans for the lagoons, end will any piping be removed as a result of the new facility?

' 13. The previous design included, "A permanently mounted pump with interconnecting piping enables solution to be pumped from any lagoon to any other lagoon and also allows recirculation within any lagoon." Will this design be used in the new process waste -

storage area or will inter-lagoon type transfers be discontinued?

14. It appears that the capacity of the lagoons is much larger than the proposed new tank capacities. Describe how flow rates will be adjusted to accommodate the new waste storage tanks.

EnvironmentalInformation

15. Describe any potential routine air emissions that will be' released from the new portion of the building as well as any new stack monitoring which will be required.

16. Describe any increase or decrease in the total curie quantity of radioactive materials ,

which are discharged to the sewer system on an annual basis. I

17. Describe any increase or decrease in the quantity of solid radioactive materials which are released for disposal. )

l

18. Describe any planned changes in the effluent and/or environmental monitoring program j currently committed to in the license.  ;

i

19. Describe any new potential accident scenarios which could result in an atmospheric l release.

20. Are all effluents which were are currently sent to the lagoons going to be sent to the

. tanks? Are any new effluents going to be sent to the tanks which are not currently being sent to the lagoons?

21.- Will the old Lagoon Uranium Recovery (LUR) process continue after the tanks are in use? . Is there a potential for there to be effluents from both the LUR process and the new tanks being discharged to the sewer system simultaneously?

(

3 Radiation Safety Information

22. Describe the health physics surveillance program for the proposed activities in the new process waste storage area.

- 23. What changes are expected to result from the new process to individual and cumulative plant occupational racfiation exposure?

)

Cnticaldv Safety

- 2d. Identify and describe in detail the criticality safety controls that will be applied in the addition to the Ammonium Recovery Facility. Specifically identify each controlled criticality safety parameter, identify all of the controls used to ensure that double

' contingency is met, describe how these controls ensure double contingency is met, and any other assumptions that were made in the analysis. Include the results of any pertinent calculations that were performed along with sample inputs.

25. What are the steps taken to ensure criticality safety in Tank 1 if the ura lium content samples from an IX regeneration indicates that the concentration er mass is too high to ensure a safe batch in the tank? What is the safe batch limit for this tank?

26. Describe in detail the process chemistry used in Tanks 2 and 5A to control uranium concentration.

27. Identify the type and location of the uranium monitors used on Tanks 1,2, and 5A.

28. What is the frequency of the periodic inspections for uranium buildup in Tanks 2 and 5A7 -

What procedure is used to identify an unacceptable buildup of uranium?

29. How are the IX columns monitored so that the concentration contained within does not

- exceed a 140 gU/l safe uranium concentration? Please provide the test data that demonstrates that the IX resin will not load to greater than this safe concentration.
