UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 APRIL 4 5 1979 Ms. Jame Schaefer, Chairman Radioactive Waste Management Study Committee LAKE MICHIGAN FEDERATION c/o 3741 Koehler Drive Sheboygan, Wisconsin 53091
Dear Ms. Schaefer:
This letter is in response to your letter dated March 18, 1979, which asked for additional information regarding spent fuel storage at six nuclear power plants near Lake Michigan.
In our previous letter to you dated March 8,1979, we stated that license amendments to increase spent fuel pool storage capacity were contested at Kewaunee and Pt. Beach but, based on settlement agreements among the parties, and on motions from the parties, both cases were dismissed by the hearing boards. The action was issued for Kewaunee on March 19, 1979, and for Pt. Beach on April 4,1979. The amendment request for Zion is before a hearing board. The Cook request is under staff review.
You asked for a copy of a generic study you referenced as being mentioned on page 2 of our earlier letter. Our letter stated that the staff was considering (and still is) the potential benefits of requiring additional pool water chemistry controls or corrosion surveillance. Until the staff deliberations are concluded, no report is available.
You also asked for other more detailed information. We have provided a tabulation plant by plant of answers to questions 1 through 8.
Answers to ques,.:,ns 9 and 10 are provided below along with additional information reinted to leakage of water from spent fuel storage pools -
your questions 2 and 8.
Further detailed information is available in the files maintained for each plant at its Local Public Document Room. A " Local Public Document Room Roster" for States bordering on Lake Michigan, which includes the plants you mentioned, is enclosed for your future use.

Ms. Jame Schaefer We believe suspended pools and built-in-the-ground pools are nearly equivalent from a safety standpoint. He do not have a preference since both concepts meet our acceptance criteria.
Spent fuel storage pools for all plants of interest consist of a reinforced concrete pool with a stainless steel pool liner. Usually there is no detectable leakage of water beyond the stainless steel liner. However, should there be a small leak rate of water, the water would be caught within the concrete pool or in leak collection channels associated with liner welds. This water is collected and treated like any other potentially radioactive water within the plant.
It would be nonitored and, if appropriate, processed for removal of radioactivity before release to the environs. This leak dollection system does not permit pool water, even in the event of a leak, to flow unimpeded into the surrounding soil.
Radioactive emissions to the environment due to storage of spent fuel have proven to be very small.
From the above discussion it is apparent that no liquid from the pool is released to the environs except by way of a controlled release path.
Scme radioactive gases, primarily iodine, xenon and krypton, may be released from the fuel, when it is first discharged from the reactor and placed in the pool.
Because the radioactivity associated with iodine and xenon decays after several months of storage in the pool, krypton would be the only significant radioactive gas remaining that Wuld be attributable to storing more fuel for a longer period of time.
Experience has demonstrated that after 4 to 6 months of storage, there is no measureable release.
We trust our responses to your questions have been i sufficient detail for you to complete your report.
Sincerely.
Harold R. Denton, Director Office of Nuclear Reactor Regulation DISTRIBUTION:
