A primary function of the power plant control system is to control the temperature of this coolant to provide the desired heat transfer rates and temperature levels in the boiler and reactor. The control system must also prevent transient excusions in the coolant temperature from exceeding the material and structural limitations of the power plant. Major obstacles to the control of transient excursions in coolant temperature are (1) the tendency of these temperature variations to be recirculated in the closed coolant loop, (2) the long transport lags associated with the coolant circulation, and (3) the large inherent time lags of thermometers measuring the coolant temperature.","PeriodicalId":284383,"journal":{"name":"Transactions of the Institute of Radio Engineers Professional Group on Nuclear Science","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130841922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The rf control is designed to accommodate the phase stability transition encountered in strong-focusing synchrotrons.

This coverage is obtained by a counting rate meter, a period meter, and a high level power indicator. At normal operating levels, the reactor is regulated by the high level power controller and protected by the high level trips. Emergency shutdown of the reactor can be initiated by any one of 54 different conditions. Since these safety circuits are almost 100% “fail safe”, careful design, good maintenance, and cautious operation have been necessary to avoid accidental shutdowns. The period trips and high level trips are provided in triplicate for safety and are coincidence-connected in pairs to guard against accidental shutdown. The use of suppressed-zero circuits has proved helpful. The theory of coincidence-connected trips is briefly discussed.","PeriodicalId":284383,"journal":{"name":"Transactions of the Institute of Radio Engineers Professional Group on Nuclear Science","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115288944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
