JE EES UNCLASSIFIED _ REACTOR DEVELOPMENT " Bechtel Corporation was selected in April 1958 from 12 companies which had responded to invitations to submit proposals for the architect-engineer services incident to design, construction, procurercent, and installation of equipment of the nuclear portion of the plant. Second Invitztion _ Construction was begun of the Rural Cooperative Power Association (RCPA) boiling water reactor project at Elk River, Minnesota, on August 5. Excavation was completed for the con- tainment vessel, The contract between RCPA and the AEC was signed June 27, 1958. The utility provides the plant site 2nd turbogenerator facilitfes, and is to operate the entire plant for 5 years. Steam produced by the reactor is to be purchased from the AEC. The AEC signed a contract with ACF Indcstries, Inc., on June 16, 1958, for the development, construction, and test operation of the reactor. The contract with the City of Piqua, Ohio, for the operation of the organic-moderated reactor was signed by Piqua on September 5. AEC, with the concurrence of Piqua, was withholding final execution of the contract until the Advisory Committee on Reactor Safeguards could considez further the safety aspects of the project. Negotiations with Atomics International on ccntract provisions for the design and construction of the reactor were In progress. Work on the Chugach Electric Association sodium-~cooled, heavy-water-moderated reactor was begun by the Nuclear Development Corporation of America (NDA) under a contract signed April 10, 1957. The initial contract, providing for research, development, and preliminary design work sas amended on June 26, 1958. Under the amended contract NDA is to perform work on the preliminary layout of the 10,000-electrical-kilowatt project for Chugach and to undertake eva2luation and conceptual design of a larger reactor of this type. Additional development, engineering design, and construction would be authorized only after the results of these studies are available. Third Invitation Ground Dreaking for the Northern States Power Company boiling water reactor is scheduled for July 1959, and research and development in support of the reactor design are in progress. The plant is to be located on the Big Sioux River, about 6 miles northeast of Sioux Falls, South Dakota. The preliminary hazards summary report and the applications for a construction per- y °% 4 E & £ rait and a sp=cial nuclear materials license were submitted to the AEC. Design was essentially complete of the critical experiment facility to be constructed at Greendale, Wisconsin, by Allis-Chalr ers Manufacturing Company. As a ccasequence of the nuclear superheat feasibility study performed under the AEC~ Northern Stztes Power Company contract, the power company has concluded that nuclear super- heat is both feasible and desirable for the “Pathfinder Plant.” On July 11 the power company submitted to the AEC a proposal to amend the existing contract so that an estimated $2,500,000 would be provided by the AEC for the additional research and development support required to incorporate nuclear superheat in the plant by the completion date of June 30, 1962. oe.) ce Oe The ccrtract between the Northern States Power Company and the AEC for the development, constructicz, and operation of the plant was signed November 19, 1957. The Allis-Chalmers Manufacturing Company is the principal subcontractor. Negotiztions were in progress on the definitive contract for the Carolinas—Virginia Nuclear Power Associates, Inc., pressurized~heavy-water power reactor at Parr Shoals, South C2rolina. Sa2sed ona previous letter of agreement, research and development work on the project was begun in May. . . o POE ARCHIVE13 7 UNGLAe. Vis _ aad SSSReee a Sa sce aoe “y ~ ~ _os “ee fa,= <r s =. | — a?
