Development of a Compact Digital Reactivity Meter and a Reactor Physics Data Processor

Reactor physics tests at initial startup and after refuelings are performed to verify the nuclear design and to assure safe operation. Analog computers and instruments are widely used for the acquisition of data, and these data are reduced by hand. These conventional procedures, however, require much time and labor. Since there has been great progress in the development of digital computers and devices, these procedures are digitalized, which successfully reduces the time and labor required for reactor physics tests.
