Evaporative removal of sodium: interim progress report and preliminary facility specification

Description: A summary of the current Evaporative Removal of Sodium (ERNA) activities at the Energy Systems Group is presented. Also included is a review of earlier work on sodium evaporation. As a result of this work it was concluded that the ERNA process was extremely successful and worthy of future consideration as a recognized process for reactor components. Also included in the report is a Preliminary Outline Specification for a large facility to remove sodium from full size CRBR fuel rod assemblies.

Sodium removal, storage, and requalification of components. [LMFBR]

Description: The objectives of this program are to devise, develop, test, and evaluate techniques for sodium removal and storage of test specimens and components, and to expand and refine, by test and analysis, the sodium removal and storage techniques and procedures for use in processing typical LMFBR components. The AI program in FY 1974 has concentrated on three major tasks: (1) Sodium Removal and Storage, (2) Bag Handling, and (3) Sodium Removal Process Development.

Sodium technology: 1-sodium removal and decontamination of components

Description: Evaporation of sodium from crevices, tensile specimens, and an IHX tube bundle mockup was studied. Glycolic acid-citric acid solutions were selected for decontaminating 304SS hot leg components. The use of 316 SS as well as 304SS to fabricate components will introduce complications to the decontamination process. The feasibility of glow discharge sputtering for decontamination is being evaluated. 14 figures, 5 tables. (DLC)

Sodium technology. Sodium removal and decontamination of components. Progress report, January-March 1976. [LMFBR]

Description: This project has several tasks, each with its own specific objectives. One of these tasks is the Sodium Removal Process Development; the first objective of which is to devise, develop, test and evaluate techniques for sodium removal from test specimens and components by the reaction of sodium with alcohol. As a part of the alcohol process development, the following activities are being investigated: (1) reaction rate studies, (2) process control and repeatability, (3) sodium-alcohol reaction chemistry and alcohol regeneration studies, (4) quality control and inspection technique development, and (5) alcohol-sodium removal process safety evaluation (Safety Report and Safety Specification). The culmination of this program will be a sodium cleaning process specification incorporating the pertinent data and other information generated by the sodium-alcohol studies.

Sodium technology. Sodium removal and decontamination of components. Progress report, July-September 1975. [LMFBR]

Description: The objectives of this program are to devise, develop, test, and evaluate techniques for sodium (Na) removal from test specimens and components by the reaction of sodium with alcohol. As a prat of the alcohol process development, the following activities will be investigated (1) reaction rate studies, (2) process control and repeatability, control and inspection technique development, and (5) alcohol-Na removal process safety evaluation (Safety Report and Safety Specification). The culmination of this program will be a sodium cleaning process specification incorporating all of the pertinent data and other information generated by the Na-alcohol studies.
