Subject:

Florida Power Corporation Crystal River Unit 3 Nuclear Generating Plant Docket No. 50-302

Dear Mr. DeYoung:

On April 8,1972, we transmitted to you 45 copies of the Florida Power Corporation response to the request for information contained in your letter of March 24, 1972. This data was to be used for a source term calculation for gaseous and liquid effluents relating to Crystal River Unit 3. This data was discussed by Florida Power, AEC and ORNL representatives at ORNL on April 13. As a result of these discussions and further review of the data, several items should be changed in our response. These changes were mutually understood and agreed upon by the attendees at the April 13 meeting. This letter is to inform you of the changes which were made.

Specifically, the response to questions 1,11,12 and 16 have been changed.

Attached please find new pages which have been updated for insertion into the response package. We are sending 45 copies to allow updating of all the original response packages if you so desire.

PRESSURIZED WATER REACTORS CRYSTAL R1VER U::1T 3 :CJCLEAR GE::ERATI!:C PLA::T BASIC DATA FOR SOURCE TEC1 CALCULATIO !

Questicn #1 - Operating Pouer (:G!t) at uhich impact is to be analyzed.

Answer:

The basis for the analysis chould be 2544 >2it which is the core ultimate thernal power level.

Question #2 - Weight of uranica loaded (first loading and equilibrium cycle).

Ansuer:

The first load of fuel will consist of 93.1 metric tons of UO2 (Table 8-2 FS AR) . The rate of uranium loaded in the equilibrium cycles will be 31.0 metric tons at each refueling. The initial fuel cycle time is 430 full power days and the equilibrium cycle is 310 full power days.

Question #3 - Isotopic ratio in fresh fuel (first loading and equilibriun cycle).

Answer:

Theamount;ofreactorcool'antincachofthe:steamgeneratorsis2030~f t 3 (Table 4-4. FS AR) . and 'the 'ac:s of hot reactor coolcat is 91,000 -lbs The mass of steam and water on the secondary side 'of each steamL gene rator ~ is 5400 and 34,500'1bs respectively at rated ful1~ power.

Question #12 - Total mass of ~ secondary coolant (1b)?'

Answer:

The mass of seconcarv coolant circulating in the cecondary l 2.6 x 106 lbs. oop is approximately This can~be broken down as follows:

Feedwater heaters 254,900 lbs Piping 20,000 lbs Steam generators secondary side (2) 69,000 lbs (steam) 10,800 lbs Paae rator 600,000 lbs Condenser Hotwell (2) 1,660,000.lbs TOTAL 2,614,700 lbs

~

In addition, there are two condensate storage tanks with a t otal capacity of_200,000-gal. (1.67 x 106 lbs.).

Answer:-

The normal. expected lock rate of primary coolant to the containment

~

build'ing is 10 gallons por day or about 2.5 lbs. per hour.

Question #17 - a. How often is the containment purged?

b. Is it filtered prior to release?
c. Are iodine- absorbers provided?
d. What decontamination factor is expected?

Answer:

It is planned to purge the reactor building periodically for personnel access for maintenance and inspection. Tentative schedule is once per month.

The reactor building purge exhause is filtered through roughing, HEPA and charcoal filters prior to release. Radioactive iodine will be absorbed by*the charcoal filters.

The charcoal filter efficiency assumed in the environmental report is 97 percent (decontamination . factor 1/3) . These filters are rated and tested at 99.93 percent ef ficiency for removal of elemental. iodine.

. Question #18'- Is there continuous air clean up for iodine in containment?
