Process Monitoring Not Directly Safety Dependent

The moderator and theimal shield shall be monitored for temperature level. The moisture content in the moderator atmosphere shall be monitored, f. Process Monitoring Not Directly Safety Dependent 

The following process parameters of an operating reactor shall be monitored. 

Individual tube temperatures shall be logged for process control and accountability information. Affluent shall be monitored to determine when fission products from failed fuel elements are being released into the coolant. 

Reactor moderator atmosphere shall be controlled to provide certain mixtures of inert gases. This shall be done to protect the moderator from being oxidized and carried off by the atmosphere and to permit closer control of the process. Temperature and flow of HCR coolant shall be monitored to protect agdinst damage of the primary control equipment. Also display of the position of the control equipment (HCR s and VSR s) is necessary to operating personnel. Total process power level is necessary to control leactor operating levels and for production accountability.
