Investigation of the Stack Gas Filtering Requirements and Development of Suitable Filters. Report No. 5 (open access)

Investigation of the Stack Gas Filtering Requirements and Development of Suitable Filters. Report No. 5

Investigation of dust loading capacity for various assemblies of air filter media on atmospheric dust has continued using the small tester described in previous reports. The effect of fiber size and packing density in Fiberglas mat has been studied. The combination of very fine fibered glass mats now in use at Oak Ridge was given special investigation. Tests were made using a coarser mat as a prefilter and an economic advantage was showm for such protection. As a result of laboratory studies on gauze backed hand sheets a paper mill run is planned to make paper comparable to #6 now used by Chemical Corps for AEC filters but stronger and lower in cost In this run the paper will be made with a reenforcing gauze backing. Fabrication work is being carried on with emphasis on two special shapes of units both of which aim to simplify installation and removal and to give better protection to operating personnel when filters are being changed. These shapes namely the hollow cube and the circular will be described in detail with sketches and test data. A 950 CFM full scale model of the hollow cube has been constructed to demonstrate the practicability of the …

Sheet rod tests

The overall testing of the vertical sheet rod system is a comprehensive program which has been divided into several phases. These phases are presented here, with a short resume of the testing required under each phase, to enable the formulation of the project proposal for the complete test program. It is intended that very detailed test requests will be issued for the separate phases as data from previous tests and further design studies indicate the exact information or data desired from a particular test.

Final report on Production Test No. 105-245-P -- Effectiveness of cadmium coated splines (open access)

Final report on Production Test No. 105-245-P -- Effectiveness of cadmium coated splines

This report discussed cadmium coated splines which have been developed to supplement the regular control rod systems under emergency shutdown conditions from higher power levels. The objective of this test was to determine the effectiveness of one such spline placed in a tube in the central zone of a pile, and of two splines in the same tube. In addition, the process control group of the P Division asked that probable spline requirements for safe operation at various power levels be estimated, and the details included in this report. The results of the test indicated a reactivity value of 10.5 {plus_minus} 1.0 ih for a single spline, and 19.0 ih {plus_minus} 1.0 ihfor two splines in tube 1674-B under the loading conditions of 4-27-49, the date of the test. The temperature rise of the cooling water for this tube under these conditions was found to be 37.2{degrees}C for 275 MW operation.

Preliminary engineer`s flow sketch and process description, Redox feed preparation from current metal (open access)

Preliminary engineer`s flow sketch and process description, Redox feed preparation from current metal

The basis feed to the Redox plant is 5,000 lb/day of uranium, supplied both as current irradiated uranium metal slugs in jackets, and as uranium compounds from the existing metal waste storage tanks. The proportions of the two feeds are chosen according to the enrichment level of the irradiated metal, so as to give a plutonium production of about 650 gm/day. The design basis has been taken as 0 to 1,500 lb/day U from the waste storage system and 2,000--5,000 lb/day of irradiated metal. Only the feed preparation from irradiated metal is discussed in this process description, and a basis of 5,000 lb/day is used throughout. The metal feed has associated with it 172.5 lb. Al and 2.5 lb. Si as slug jackets, and contains about 650 gpm. plutonium and 3 {times} 10{sup 5} curies of gamma-emitting fission products (FP). The purpose of the feed preparation section is to remove the aluminum and silicon, and to dissolve the uranium as an aqueous solution for feed to the Redox extraction battery. Secondarily, it is tentatively proposed to provide equipment in this section to achieve a preliminary decontamination from ruthenium, which is poorly handled by the Redox extraction system, and from FP …
