10-MWe pilot-plant-receiver-panel test-requirements document: Solar Thermal Test Facility

Plans are presented for insolation testing of a full-scale test receiver panel and supporting hardware which essentially duplicate both physically and functionally the design planned for the 10 MWe pilot plant. Testing includes operation during normal start and shutdown, intermittent cloud conditions, and emergencies to determine the transient and steady state operating characteristics and performance under conditions equal to or exceeding those expected in the pilot plant. The effects of variations of input and output conditions on receiver operation are also to be investigated. A brief description of the pilot plant receiver subsystem is presented, followed by a detailed description of the receiver assembly to be tested at the Solar Thermal Test Facility. Major subassemblies are described, including the receiver panel, flow control, electrical control and instrumentation, and the structural assembly. Requirements of the Solar Thermal Test Facility for the tests are given. System safety measures are described. The tests, operating conditions, and expected results are presented. Quality assurance, task responsibilities, and test documentation are also discussed. (LEW)

Investigation of Hot Cracking in Deep Penetration Electron Beam Welds (open access)

Investigation of Hot Cracking in Deep Penetration Electron Beam Welds

A defect in a deep penetration electron beam weld of 304L stainless steel to 21-6-9 stainless steel has been identified as a centerline hot crack. The study discussed in this report was made to define and to eliminate the cause of cracking.

Investigation of the electrolytic dissolution of plutonium (open access)

Investigation of the electrolytic dissolution of plutonium

Experiments have shown that it is possible to dissolve plutonium electrolytically in a nitric acid solution. Parameters such as current density and electrolyte composition have been investigated and are discussed. Also included are suggestions for future work.
