ASTR AND GTR INSTRUMENTATION MODERNIZATION.
GENERAL DYNAMICS/FORT WORTH TEX NUCLEAR AEROSPACE RESEARCH FACILITY
Certain items of GTR, ASTR, and facility equipment were modified or replaced to provide safer and more reliable reactor operation. A reliable alarm system indicating potentially dangerous and unsafe conditions in the nuclear area was designed and installed. Trip circuits were procured, tested, and installed as the power-level-indicating and level-scram channels were modified to increase their reliability. A magnet power supply for the GTR, compatible with the modified scram channels, was designed and installed. Identical Log-N and Period channels were procured and installed in the GTR and ASTR. The response of the modified channels to a step input was evaluated. Author
