KMI + LANL Treatment of Remediated Nitrate Salts
The Los Alamos National Laboratories have entrusted KMI Zeolite as the go-to supplier for the purest and most stable material for the long-term storage of nitrate salt waste, a byproduct of weapons grade plutonium production.
Remediated nitrate salts are condensed and encased in KMI Zeolite. Due to the stable nature of our mineral, and the adsorbing qualities, KMI Zeolite can contain this nuclear waste for thousands of years.
The sorptive quality of KMI Zeolite plays an important role in retarding the migration of radionuclides that occur in solution as simple cations, specifically Caesium, Strontium & Barium (Cs, Sr, Ba). The short-lived nuclides of these elements account for 2/3 to 3/4 of the total waste activity at 100 years and the presence of zeolites provides assurance against significant movement of these radionuclides if there are any unforeseen early canister failures.
Storing Remediated Nitrate Salts
KMI Zeolite has been utilized by LANL as a waste encapsulation tool, and is specified for two types of nitrate salt remediation and storage.
Stabilization can be performed by mixing in zeolite with nitrate salts at a rate of 1.2:1, with or without cementation.
Setting The Standard
In February 2014, prior to KMI Zeolite’s work with LANL, there was an explosion in the LANL storage facilities that resulted from using an organic kitty litter instead of an inorganic clinoptilolite zeolite. This multi-billion dollar mistake led the research department to KMI Zeolite because we have the highest purity clinoptilolite zeolite in North America and a strong commitment to the continuous improvement of our quality assurance programs.
KMI Zeolite has worked closely with Los Alamos National Laboratories to develop and improve upon our quality assurance programs, equipment & reports that ensure the consistent delivery of the highest quality clinoptilolite zeolite for radioactive waste encapsulation and other applications. In the last few years we have also sent material to Oak Ridge National Laboratory and Pacific Northwest National Lab as well.
