Since brazing was the method selected for joining the stainless steel SM- l reactor fuel element, corrosion studies were conducted on various potential brazing alloys to evaluate their resistance under the approximate pressurized- water conditions of the SM-1. The program consisted mainly of testing type 304L stainless steel T'' joints brazed with selected alloys in quiescent, degassed, and deionized autoclaved water at 565 deg F under 1200-psi pressure. In the initial phase of the investigation, tests were limited in duration to l000 hr in order to quickly screen some 18 potential alloys for longer time testing. Based on weight-change data and the metallographic examinations, five of the 18 alloys exhibited sufficient corrosion resistance to warrant further investigation. These alloys were subjected to autoclave tests of 12 and 16 months. In these extended tests, 1 cc O/sub 2/liter and a mixture of 1 cc O/sub 2/liter plus 50 cc H/sub 2/liter, respectively, were added to the water to more closely simulate SM- 1 reactor water conditions and to evaluate the effect of different gaseous additions on the corrosion behavior of the alloys. On the basis of weight-change data and metallographic examination after long-term exposure of the tested stainless steel-base joint; these …

C Reactor experienced two severe fuel failures, one in process tube 2562 on 10-27-67, and one in process tube 3361 on 12-27-67, both resulting in major efforts to effect their removal. The intent of this document is to present a summary of the action taken for the removal of the failed elements.

With the use of smooth-bore Zircaloy-2 process tubes and self- supported fuel elements on a large scale at the K Reactors, establishment of the operating characteristics of this fuel element-process tube configuration is imperative. Under authority of Production Test-IP-409-A, two smooth-bore Zircaloy-2 tubes were routinely charged with KVNS fuel elements. Approximately 520 KVNS fuel elements have been irradiated in this facility. In Production Test-IP-572-A, the coolant temperature distribution in the annulus of the KVNS fuel element-process tube system is being evaluated as a function of fuel element support height. This production test supplement will provide data for further defining the operational characteristics of the self-support fuel element concept.

The objective of this test is to produce 50 milligrams of neptunium 239 for a process stream study in the Purex plant. The efficient recovery of neptunium 237 as an alternate product produced at HAPO is presently impaired by the lack of knowledge of the distribution of neptunium 237 in the several Purex process streams. Present methods of following the neptunium 237 through the process streams involves inadequate alpha counting techniques. However, neptunium 239, because of its discrete gamma decay energy, can be readily identified in the process stream. As a result, the neptunium 239 produced by this irradiation will serve as a gamma-emitting tracer for the neptunium 237 in the Purex process stream.

This investigation report discusses the exposure of a maintenance craftsman to a radioactive particle found on his face which could have contributed to a dose as high as 4.6 rads. The craftsman had been working at the discharge area. (JL)

It is noted that in high-temperature He-cooled graphite reactors, sufficiently high levels of gaseous impurities can lead to transport and corrosion effects. The possible effects of these reactions in graphite-moderated reactors designed to operate at a He-coolant pressure of a about 20 atm. were investigated. Results are included on C transport, steam-graphite reactions, and deposition of C on surfaces. (J.R.D.)
