Although the "design" section is consistent with available information, I've always been skeptical of the claim that the tx-15 mostly utilized natural Lithium-7 in the fusion secondary. Refining natural lithium to lithium-6 is a costly process. If lithium-7 worked essentially as well as lithium-6, why would any nation bother to produce lithium-6? — Preceding unsigned comment added by 2604:6000:6F40:2800:C12:9ACF:88CD:8F0 (talk) 05:51, 11 September 2020 (UTC)
