Abstract

This paper describes the advanced instrumentation and control technology that has been applied to the modular high-temperature gas-cooled reactor (MHTGR) to meet the top-level goal of safe, economical power. The MHTGR, with its four reactor modules and two turbine generators, will be controlled to respond to a variety of normal and transient operating modes. The overall objective of the plant control, data, and instrumentation system (PCDIS) function is to assist plant operations personnel in maintaining highly reliable control of the MHTGR. The MHTGR design simplicity and passive response, in conjunction with the plant supervisory control system, have yielded a major reduction in operator workload. The plant does not require safety-related operator actions, nor does it require the control room or its equipment to be safety related. Therefore, plant control is accomplished from a central control room by two operators and one supervisor via the supervisory control system.
