The basis for this claim was two reports from the Lawrence Livermore National Laboratory UCRL-4725, "Weapons Development During June 1956", and UCRL-5280, "Weapons Development During June 1958", which contained detailed information on thermonuclear weapon design.
这一主张的基础是勞倫斯利福摩爾國家實驗室的两份报告，分别是UCRL-4725《1956年6月期间的武器开发》和UCRL-5280《1958年6月期间的武器开发》，其中包含有热核武器设计的详细信息。
