EnerCom Interview with Deep Fission CEO Liz Muller

At the 30th annual EnerCom Denver conference, we interviewed Deep Fission CEO Liz Muller. Deep Fission is harnessing three technologies—pressurized water reactor technology, drilling, and geothermal—to solve the nuclear waste problem by storing nuclear waste in a borehole one mile underground. They expect to be able to lower the cost of conventional nuclear power by about 80% and decrease the time from construction start to reactor operations in about six months.
