APPLICANT'S RESPONSES TO MAFIE"0N INTERRCGATORIES

1. Does Consu::ers Power Cc=pany and/or Dow Chemical Campany have a present plan to make a future application to the Michigan Water Resources Commission to construct a dam across the Tittabavassee River for the purpose of creating a reservoir should a construction s

permit and/or operating license be granted by the AEC7 No.

2. What components of gaseous effluents vill be discharged into the atmosphere from the operation of the proposed plants?

As shown in Table 11-3 of the Midland Plant PSAR, krypton and xencn are both present as dissolved gases in the primary coolant

and vill eventually be released to the environment.

l l Radioactive gases vill be held up in the plant for 30 days to allow natural decay of the va;-ious isotopes. After 30 days' holdup, the amount of gases released will represent less than.6.5%

/

of AEC limits at the site boundary.

Hydrogen and nitrogen vill also be released with the above radioactive gases. ,

3 Can the applicant absolutely guarantee that release of rcaio-active effluents (gases, steam and vaste heat) into the air at the site of the proposed nuclear plants vill not accumulate and be hazardous to hmtan health?

Applicant's gaseous emissions from the plant vill be only a few percent of 10 CFR Part 20 limits. Process steam is created in tertiary heat exchangers designed to isolate such process steam from the primary and secondary systems of the reactor. A monitoring system vill ensure that no radioactivity is added to the feedvater by the process of transforming it to steam in the tertiary system heat exchangers. Waste heat is not radioactive.

4. Has the applicant made a detailed study of meteorological condi-tiens in the Saginav Valley for the past ten years?

a. If the answer to No. 4 is "yes", is such data available for inspection?

b. Under whose custody and control and where located?

As noted on Page 2A-3 of Section 2A of the Midland PSAR, Consumers Power Canpany has made a detailed study of the meteorological conditions in the vicinity of the site for the past ten years.

a. Such data is available for inspection. The majority of the data is presented in the PSAR.

b. The original "rav" data is in the custody of q Dow located in Midland.
