(L ... .- e Reactor was research and materials testing, andthat use of the MTR for Fo-21O production should have second priority, It was recalled in this connection that the Joint Committee had been advised at the meeting on April 9, 1951, that operation of the MITR wo~d reduce Ucs. dependence on the Chalk River NRX reactor for important special irradiations. After further discussion, the Commission: a, NOTED that the Hanford reactors will be operated to produce tic maximum amount of plutonium; in so doing, they may be unable to supply all production requirements for Po-21O; .. .,,, ,, .. :,., b. AUTHORIZED the use of the MTR for the production of 3?0-210 to compensate for any deficiency in production of this material at Hanford, to the extent that such production would not supersede the primary purpose of the lMTR; c, AUTHORIZED the design of a high-performance reactor which would be optimized for production of Fo-210, and selection of a site for construction of such a reactor; d. NOTED ,. that; (1) The Director of Military Application will proceed to reexamine the present activity limit specifications for initiators and the principle of maintenance of parity between cores and initiators, with the object of possible reductions in I?o-21O requir ements; (2) The Directors of Research, Reactor Development, and Production will proceed to examine other means of reducing the Po-210 requirements and optimum methods for its production; (3) The results of these mission consideration; studies will be presented for Com- e. NOTED that as soon as possible, cost estimates, time of construction estimates, and performance studies on the optimized reactor in c above would be prepared so that the need for proceeding with suck a unit could be analyzed in light of the outcome of the studies noted in — d above; -169 -
