During the Cold War, SRS produced WGPu for as much as several hundred ppy.
Building 332 at Lawrence Livermore National Laboratory (LLNL) used to have the same HC and SC as PF-4, and formerly handled large quantities of WGPu, such as to build nuclear explosive devices for testing.
* Use RLUOB for AC with 26 grams of WGPu. Since it is a Radiological Facility, that is the most it can hold under existing regulations.
* Convert RLUOB from a Radiological Facility to an HC-3 building, which would permit it to hold 1,750 grams of WGPu. LANL estimated that this conversion would cost between $15 million and $50 million.
While RLUOB is not HC-3, LANL calculated that the radiation dose resulting if RLUOB, with 1,000 grams of WGPu, collapsed in an earthquake would be far below the standard set by DOE.
What would be the adverse consequences if RLUOB were operated as is with 1,000 g of WGPu?
