Dear Dr. Seaborg:

) Since 1958, the N-Senactor has been oor.sidered at a ausber of Commaittee
- ami Subcommittee meetings. At the earlier ametings, attention was directed to the novel confinement scheme which is based on release of 8[
excess building pressum from a possible accident before fission pro-(
ducts are released from the fuel. The complete design of the plaat 14-15,1963, was reviewed at a Subcommittee meeting at Banford om August and the design was considered further at this fifty-first Committee meeting.
The Coznittee cournented on aspects of the New Production Anactor in letters written on March 14, 1960 and April 10, 1962. These letters stated that the proposed confinement scheme was an improvement en the protection at the other Emnford reactors against fission product release; that the operation of NPR will not significantly increase the present hasards of the Hanford operations; and that.the RPR on this site appears acceptable as a power mactor, assuming that the pmposed ecafinement Review of the complete sjuteni has not systes operates as intended. ,
