PRFLIMINARY ASFECTS OF NORTHERN STATES POWER COMPANY'S APPLICATION FOR A CONSTEUCTION PERMIT FOR ITS PROPOSED MONTICELLO NUCLEAR GENERATING PLANT The Northern States Power Company has submitted an applicated dated August 1,1966 for a utilizatien Facility License and Construction Permit for its Monticello Station Unit No. 1. The site is located on the west benk of the Micciccippi River about 3 miles northveet of Monticello. Minnesota. The 1325 acre site vill have a minimum exclusien distance of about 1600 ft. to the south of the reactor building and the nearest residence in at 1/2 miles. The nearest population center, St. Cloud, 1unnesota (population 3h,000) is about 22 miles northwest of the site.

The plant, a direct-cycle General Electric boiling-water reactor, will be designed for operation at 1675 MWt with an initial 31 cense limit lh69 MWt and a net electrical output of h72 Kn'. The Monticello Nuclear Generating Plant is similar to Dresden Units 2 and 3 and Mil] stone Point and also, except for the use of fet pumps, Oyster Creek and Nine Mile Point nuclear power plants.

One prominent novel feature of this plant is that the reactor vessel vill te field fabricated. Although the Facility Description and Safety Analysis Report does not have any discussion of this tatter, representatives of USP have stated that this mode of fabrication is planned.

A second novel feature is that cooling towers will be provided to remove heat frcm cendenser circulating water during those periods when river flow is too low for adequate heat rejection to the river. As a result limited volumetric diluticn of radioactive liquid vastes may require radioactive vaste storage or holdup tank capacity exceeding that fcr other equivalent plants.

2 j The -Facility Leecription and Safety Analysie Report provides only a casual re-Terence to the cooling tovers.  !

The ACBS at its seventy-third meeting on May 5-7, 1966, reviewed the site.  !

proposed by Northern States Power Company for construction of a boiling veter reactor to be operated at 1469 MWt and concluded in a letter to the Chairman- ,

t USAEC, that "the Monticello site is acceptable for a reactor of the Eeneral type and power level proposed if adequate containment and associated engineered safe-guards are provided." The DRL Staff in a report to the Advisory Committee on.

Reactor Safeguards' dated April 21, 1966 envisioned no unusual siting ~ problems ,

for a General Electric boiling water reactor at the proposed Monticello site  ;

taaed on a report furnished by NSp and a visit to the site by staff members on r

April 13, 1966.

Enced on a preliminary review of the application, there appear to be no Safety problema which cannot be resolved; however, field fabrication of the reactor vessel, as a "first of a kind" and as an important precedent for the

.. nuclear industry, vill receive special attention. .
