Abstract : The pressure vessel surveillance program for the Army MH-1A, barge-mounted reactor was designed by NRL. The NRL-fabricated hardware for the surveillance program included two capsules for vessel wall locations in the reactor, two capsules for accelerated exposure locations, and six capsules for above-core, thermal control locations. Schematic drawings indicate the relative location of the test specimens, neutron flux monitors, and temperature monitors in each capsule section. The manufacturer of the vessel saved the reactor nozzle cutouts from the upper shell-course ring forging for test purposes. The Charpy V-notch and tensile specimens contained in the capsules were machined from one of these reactor nozzle cutouts. Schematic drawings show the location of each test specimen in the parent material. Selected Charpy-V and tensile specimens have been tested to develop preirradiation properties of the AISI 316 stainless-steel reactor vessel for future reference. (Author)
