Access anywhere, anytime: Nuclear power, Ice Camp, and Rickover’s enduring standard of excellence
Admiral William Houston
As U.S. Navy submarines surface through Arctic ice during Ice Camp 2026, they demonstrate more than operational proficiency in one of the harshest environments on Earth. They reaffirm a technological truth first proven in August 1958, when the USS Nautilus completed its submerged transit of the North Pole: nuclear power enables access anywhere, anytime.
The Arctic is unforgiving, with vast distances, extreme cold, shifting ice, and no logistical infrastructure. Conventional propulsion is constrained by fuel, air, and endurance. Nuclear propulsion removes those constraints. Only a nuclear-powered submarine can operate anywhere in the world’s oceans, including under the polar ice, undetected and at maximum capability for extended periods. Nuclear power provides sustained high speed and the endurance to reposition across the globe without refueling.

A shielding layout for a 40-MeV electron linac is presented. The linac building consists of 15-cm concrete roof and walls, and 2-m-thick shielding walls for horizontal shielding. No shielding roof covers the linac, which reduces the capital cost of the facility building. Though the present shielding layout allows an operation of up to 11.8-W averaged beam power, experimental dose equivalent rates are found to be much greater than that predicted by the skyshine formula. Monte Carlo (MCNP 4C) simulations indicate considerable contributions of radiation scattering by the thin roof and walls.
