Australian Invented SILEX Process Also For Weapons Grade HEU? "SILEX Treaty"

Following "Australia's Silex-GLE Completes Large Scale Uranium Enrichment Demonstration Testing" of September 17, 2025 at https://gentleseas.blogspot.com/2025/09/australias-silex-gle-completes-large.html

The Australian invented SILEX laser-based uranium enrichment process will very likely be used for parallel programs for the production of:

-  Low Enriched Uranium (LEU) less than 20% Uranium (U) 235, at the Paducah Laser Enrichment Facility (PLEF) in Kentucky, USA. Enrichment is not a linear process. Getting to 19.99% LEU might be 80% of the enrichment effort towards much higher percentages in the HEU range at US Department of Energy HEU facilities (see below and here); and 

-  (from 28 October 2029 it may become legal to use SILEX technology to enrich past 20% U-235)** ie. for Highly Enriched Uranium (HEU). PLEF enriched LEU might then be passed on to US Department of Energy HEU production facilities including the Los Alamos National Laboratory (LANL), New Mexico and Oak Ridge National Laboratory (ORNL) Tennessee, USA. HEU = more than 20% U-235 and up to 97% higher end weapons grade and for naval reactor fuel.

Los Alamos National Laboratory has a staff of 14,150. Amongst other things its mission is to "solve national security challenges" which includes "Weapons Systems" see here. See a Los Alamos documentary on Laser Isotope Separation (eg. Uranium Enrichment) below.

**  The "SILEX Treaty" of 28 October 1999, might expire after 30 or 31 years. See the wording of the "SILEX Treaty" between Australia and the USA, specifically:

[from 28 October 1999] "the agreement will remain in force for 30 years [until 28 October 2029]. It can be extended if both parties agree or terminated with one year's written notice (Article 16);"

I found out about the "SILEX Treaty" from this mention.

Here and above is Los Alamos Scientific Laboratory Presents: Laser Isotope Separation uploaded May 7, 2021 by Alan B. Carr a Program Manager and the Senior Historian for the Los Alamos National Laboratory. Here is his website.

This Los Alamos documentary doesn't mention SILEX, But this may be because the documentary was made before 1982, while SILEX was developed in the 1990s. To back this up the hitherto named Los Alamos Scientific Laboratory (quoted in the documentary) was renamed the Los Alamos National Laboratory in 1981. 

At 10:04 into the documentary video "1976" is mentioned and reference is made to physical % enrichment limits. By 2025 there may be no % physical enrichment limitations.
