President - Engineering 6 F. Logan Operating Croup'36 V. Benaroya Fayetteville Street Raleigh, North Carolina 27602 Gentlemen:

In connection with the preparation of our Envixonmental Statement fox the Shearon Harxis Nuclear Power Plant, Units 1, 2, 3, and 4, we have established a program to determine the type and quantities of nuclides to be released annually from this facility Personnel from the Oak Ridge National Laboratory are assisting us in this part: of the environmental review. For this program we need basic, data for a source term calculation for a gaseous and liquid effluent analysis that specifically relate to-Sheaxon Harris Nuch of this information may already be in your applica-tion or Environmental Report, but to expedite the xevLew we require a tabulation of this information as indicated in the enclosed list. Any data that are inconsistent with information in your SAR or Environmental Report should ba identified. Forty-five. copies of separate answers should be submitted fox (1) the facility as presently designed and (2) any pro)ected design changes.

This information should be provided by June 7, 1972, If it Xs impossible to meet this schedule, p1ease let us knoFr. He would like to,meet with you and representatives of other utilities at Oak Ridge on June 15, 1972, to discuss the use of this information in our'nvironmental analysis. The meeting may extend into the next day. Contact'Ifr T. Row of ORNL (615-483-8611, Ext. 31423) for meeting arrangements.

Sincerely,

10. Primary coolant flow rate (lb/hr).

ll. Mass of steam and. mass of liquid in each generator (lb).

12. Total mass of secondary coolant (lb).

13. Turbine operating conditions (temperature F, pressure psi, flow rate, (lb/hr) .

14. Total flow rate in the condensate demineralizer (lb/hr) .

18. Is there a continuous air cleanup for iodine in the containment? If so, what volume per unit time is circulated through it? What decontamination factor is expected? At what concentration will purging be initiated?

19. Give the total expected continuous letdown rate (lb/hr).

a. What fraction is returned through the demineralizer to the primary system'? What is the expected. demineralizer efficiency for removal of principal isotopes?

o~e 2

b. What fraction of this goes to boron control system? How is this treated, demineralization, evaporation, filtration?

c. Is there a separate cation demineralizer to control Li and Cs?

20. What fraction of the noble gases and. iodines are stripped. from that portion of the letdown stream which is demineralized to the primary return system? How are these gases collected? What decay do they receive prior to release?

21. What fraction of the noble gases and iodines are stripped from that portion of the letdown stream which is sent to the boron control system?

How are these gases collected? What decay do they receive prior to release?

22. Are releases from the decay tanks passed through a charcoal absorber?
