BOISE, Idaho—The U.S. Department of Defense is taking input on its plan to build an advanced mobile nuclear microreactor prototype at the Idaho National Laboratory in eastern Idaho.

The department began a 45-day comment period on Friday with the release of a draft environmental impact study evaluating alternatives for building and operating the microreactor that could produce 1 to 5 megawatts of power. The department’s energy needs are expected to increase, it said.
