This report, published two days after President Lyndon B. Johnson issued a statement calling for the federal registration of all firearms as well as federal licensing of all firearm owners, contains selected information published by the Justice Department, the Harvard, Northwestern University, and Albany Law Reviews, and the National Rifle Association, discussing the second amendment and its implications for the American people.

The Hanford production complex is potentially capable of producing and processing a wide variety of isotopes. Some of these have been identified as specific R & D missions (i.e., plutonium-238, transplutonium elements and tritium), and the technical programs supporting these efforts are described elsewhere in this series of Five-Year Program documents. Capability to produce other isotopes has been demonstrated in the successful production of `clean` uranium-233, in the recovery of large quantities of selected fission products, and in the development of process technology for polonium-210. Active R & D programs are underway to improve the technical bases for producing these isotopes, and for demonstrating the capability of producing others. Formerly, several R & D missions were identified and conducted to define the technical factors for initiating production of these isotopes. Either the efforts on these missions have declined because of decreased emphasis (polonium-210) or because of the advanced status of the technology (uranium-233), or the efforts have generally been modest (cobalt-60). These several efforts are now combined into one R & D mission, other isotopes, and they are described in the following pages of this document.

There are three principal facets to the Pu-238 Program which are important to Richland. First, reactor neptunium production rates can be materially enhanced by judicious fuel management plans. Second, significant improvement in production efficiency and costs may be made if the Pu-238 production step (irradiation of Np-237) were sites at Richland. Further, Richland reactors have ample capacity, without reducing power, to irradiate all neptunium from government and commercial reactor sources which has been forecasted well into the 1980`s. Third, a separate Pu-238 production process, that of irradiating Am-241 (obtained from power reactor plutonium returns), offers an attractive and competitive means to materially supplement Pu-238 from the Np-237 route. The first two of these aspects of the Pu-238 Program are being pursued actively, particularly in light of firm and predicted requirements for Pu-238. Technological development for irradiating and processing Am-241 will be performed in the near future.

This report itemizes the irradiations performed by Testing and Irradiation Services for Battelle-Northwest. It lists the material being irradiated, awaiting disposition and material shipped during the report period.

The annual report on the previous fiscal year`s accomplishments attributed to process development has been provided about six months after the end of the fiscal year. In accordance with a recent request, the date of this report has been advanced to coincide with the end of the fiscal year. Further, the scope of the report has been expanded to include a narrative assessment of program accomplishments. Because of this enlargement of scope some liberty has been taken in identifying new products and development gains. The Douglas United Nuclear process development program can be categorized into the following: (1) Cost Reduction, (2) Increased Plant Life, (3) Versatility, and (4) Safety and Licensability. The overall program goal is to develop technology that will provide greater efficiency at reduced cost and yet be responsive to an increasing variety of product requirements while continuing the excellent plant safety performance. The goal is significant when considered in view of increasing budgetary pressure. The projected defense requirements after 1975 are not expected to require the full capacity of the Hanford reactors. However, based upon the anticipated growth of electric power requirements and space exploration power requirements, the current full productive capacity of the Hanford reactors will …
