Production Test IP-546-A. consisting of 20 charges for the purpose of irradiating the first hot die sized fuel elements was charged in C-Reactor July 27, 1963. A second tests PT-IP-616-A containing a total of 19 charges had been charged on two separate outages; 13 land 6 tubes on September 28, 1963 and October 30, 1963, respectively. Fabrication of test quantities was becoming more routine and additional irradiation tests were planned. This report summarizes the fabrication of hot die sized fuel elements originally intended for Production Test IP-630-A, but changed to ``Supplement ``A`` to Production Test IP-546-A, Irradiation of Diffusion Bonded Fuel Elements,`` HW-75465 E. The production test was changed due to unexpected growth behavior of hot die sized fuel during irradiation.

During the major part of October the N-Reactor was shut down for dump condenser repair, scheduled maintenance and equipment modifications. Work on dump condensers was successfully completed and the construction and tie-in of steam generator cell No. 4 was accomplished. Power ascension was initiated on October 24 and the N-Reactor in now operating with all five steam generator cells in full service. Process physics, in-plant testing, and technical activities are described in this document.

Highlights include production program and development program reviews at the Mallinckrodt Chemical Works, and production and development at the National Lead Company of Ohio. Activities at the Savannah River Plant are briefly discussed. General Electric at HAPO reports from the irradiation processing department and the N-Reactor department. The Hanford laboratories report on fuel element work.

The irradiation performance of Zircaloy-2 clad thorium-uranium fuel elements under water-cooled power reactor conditions continues to be excellent. Fuel swelling continues to be no more than that required to accommodate the fission product atoms. Measured fuel swelling is less than one percent at 3.1 {times} 10{sup 20} fissions/cc (9,300 MWD/T). The addition of iron and aluminum to metallic uranium fuel elements has been shown to markedly decrease fuel swelling. The improved swelling performance is attributed to a decreased tendency to form mechanically induced porosity and is believed to result from the dispersed second phase particles inhibiting the movement of structural defects formed as a consequence of the anisotropic growth of alpha uranium.

Hot die sizing (HDS) is a process being investigated to replace the existing AlSi brazing process. Hot die sizing consists of sizing a nickel-plated core and aluminum can assembly with cold dies to produce a diffusion bonded aluminum clad fuel element. Upon completion of fabrication of the first natural uranium hot die sized fuel elements for production test IP-546-A, the next step in evaluation of the process was to assemble enriched fuel for further irradiation testing. This report summarizes the fabrication of 0.947% U-235 enriched fuel elements for ``Production Test IP-616-A.``

With recent concern for downcomer capacity at most areas, it seems appropriate that a survey be made to determine what instrumentation and data are available. The following is a brief description of the available instrumentation and data for KE, KW, H, F, DR, D, C, and B reactors.

Candidate canning materials were tested in contact with molten stand-ins for Pm metal; nondestructive tests were conducted. Related studies included americium processing, uranium-233 support, Ce-Pm separation, and technetium analyses.

It was thought that if a multi-detector device could be developed, the scanning time would be greatly shortened, with such consequent advantages as being able to work with lower dose of radiation, to obtain serial determinations, and to work with shorter-lived isotopes.
