Brown was the original whistleblower of the Thermo-Lag 330-1 scandal, which involved an endothermic material manufactured by Thermal Science Inc., also doing business as Nu-Chem, Inc. and later as TS Holdings Inc. of St. Louis, Missouri. Thermo-Lag was used to provide circuit integrity to wiring running between the nuclear reactors and the control rooms within the power stations. The purpose of the circuit designs was to ensure that in the event of a fire, the wiring remained operable so that workers could shut down reactors to prevent a nuclear meltdown.
