This refinement over the ARMF-I meant that operators could process data quickly in electronic computers. Designers of the ARMF-II benefitted from previous experience with the ARMF-I and the

electronic computers. ARMF-I and ARMF-II were housed in a 40-foot by 60-foot cinder block building located just east of the MTR canal tunnel; the building was designed from the initial concept for two reactors. These facilities were swimming-pool-type reactors with light-water moderated cores made up of plate-type fuel elements containing high

The
Advanced Reactivity Measurement Facilities, ARMF-I and ARMF-II, were nearly identical critical facilities and were used almost exclusively for measuring reactor physics parameters, such as reactor-spectrum cross sections and resonance integral cross sections. They were designed to (a) have large

The ARMF-II, a reactor located in a small pool in a building east of the MTR in the Test
Reactor Area, was used to determine the nuclear characteristics of reactor fuels and other materials subject to testing in the MTR. Together with the MTR, the reactor helped improve the performance, reliability,

National Reactor Testing Station near the Materials Testing Reactor (MTR). Being located near the MTR permitted measurements of short-lived fission products and transmuted isotopes. By use of the capsule 'transfer tube' connecting the MTR and ARMF

ARMF-I and ARMF-II were near identical pool reactors. The greatest difference between the two ARMF reactors was that ARMF-II had a “readout” system which automatically recorded measurements on IBM data cards. This refinement over the ARMF-I meant that operators could process data quickly in
