The U.S. Army’s Deactivated Nuclear Power Plant Program
The U.S. Army Corps of Engineers (USACE), Baltimore District, is home to the North Atlantic Division’s Radiological Health Physics Regional (RHPR) Center of Expertise, which is leading the decommissioning of Army reactors.
From 1956 to 1976, the Army’s nuclear power program operated several small nuclear reactors to confirm the feasibility of their meeting military power needs on land. Three Army reactors were deactivated in the 1970s and placed into safe storage awaiting future decommissioning.

SCK.CEN 's VISIONI has the capability to expose candidate plasma facing materials to tritium _ deuterium plasmas at ITER first wall conditions. To protect operators against exposure to a tritiated atmosphere VISIONI must be placed in a secondary confinement. The current Tritium lab at SCK.CEN has a walk-in process cell which can be used to enclose the plasma chamber and diagnostics of the VISIONI setup, which have a limited tritium inventory. This allows easy accessibility to the setup in a well-ventilated environment. Routine operations should be conducted from outside the process cell and maintenance operations can be conducted from within the process cell with proper protections. The tritium storage and supply can be enclosed in a glove box with a dedicated air detritiation system which is activated during an experiment or in case of an incident. The detritiation system will oxidize tritium and capture it on molecular sieves. By using this confinement approach it is possible to expose materials to a tritiated plasma while maintaining good accessibility of the VISIONI setup. This paper describes the proposed confinement system and compares it to the most common approach where the entire system is enclosed into one large glovebox.
