Scoping studies: behavior and control of lithium and lithium aerosols
Abstract
The HEDL scoping studies examining the behavior of lithium and lithium aerosols have been conducted to determine and examine potential safety and environmental issues for postulated accident conditions associated with the use of lithium as a fusion reactor blanket and/or coolant. Liquid lithium reactions with air, nitrogen, carbon dioxide and concretes have been characterized. The effectiveness of various powder extinguishing agents and methods of application were determined for lithium-air reactions. The effectiveness of various lithium aerosol collection methods were determined and the volatilization and transport of radioactive metals potentially associated with lithium-air reactions were evaluated. Liquid lithium atmosphere reactions can be safely controlled under postulated accident conditions, but special handling practices must be provided. Lithium-concrete reactions should be avoided because of the potential production of high temperatures, corrosive environment and hydrogen. Carbon microspheres are effective in extinguishing well established lithium-air reactions for the lithium quantities tested (up to 10 kg). Large mass loading of lithium aerosols can be efficiently collected with conventional air cleaning systems. Potentially radioactive species (cobalt, iron and manganese) will be volatilized in a lithium-air reaction in contact with neutron activated stainless steel.

The Bureau of Mines investigated the adaptability of the Meteorology Research Inc. (MRI) nephelometer and the Sinclair-Phoenix smoke meter for use in routine, analytical, smog-chamber experiments and to compare their responses to aerosol during these experiments. Both instruments' sampling systems were modified--smaller size sample input systems were studied using the nephelometer and a secondary sample system was added to the smoke meter to allow measurement of Aitken or condensate nuclei. Both instruments were easily adapted for use with small smog chambers and both displayed good precision and sensitivity to aerosol. A correlation was shown to exist between the two instruments'more »

Scoping tests on the potential for lithium/aluminum steam explosions in an SRS Septifoil
In May 1991, WSRC/SRL requested that ANL conduct five scoping tests in order to investigate the potential for self-triggered lithium/aluminum steam explosion in an SRS Septifoil. This work was to support the ongoing SAR Chapter 15 analysis for the K-reactor restart at SRS. The five tests were successfully completed over a two-month period between June and August 1991. The conditions for the five tests were specified by the WSRC designated technical manager, Dr. Phillip G. Ellison. While the tests were carried out in an existing facility at ANL, WSRC/SRL provided the test sections which consisted of a three-foot long SRSmore » -
