HYBRID INCORE DETECTOR ASSEMBLY FOR CORE MONITORING AND PROTECTION

摘要

PURPOSE: A hybrid in-furnace measurement instrument group for core monitoring and core protection is provided to more accurately measure a state of core by using vanadium measurement instrument and platinum measurement instrument. CONSTITUTION: A platinum measurement instrument (130) performs a core protection function. A vanadium measurement instrument performs a core monitoring function. A background measurement instrument (120) performs the core monitoring function. A core exit thermocouple (140) is integrated into one. The vanadium measurement instrument consists of five numbers of vanadium measurement instruments.
