AN EVALUATION OF THE NMSR PROPOSED RAPID MANUVERING RATES

The maneuvering rates originally proposed are described in the contract specification, as follows: 20 to 60% in 40 seconds, 60 to 80% in 40 seconds, 80 to 40% in 40 seconds, 40 to 20% in 40 seconds. As these rates are relatively slow (1% per second) a relatively simple reactor control system was specified with control rod mechanisms of fixed speed type. The Atomic Energy Commission requested a study of the feasibility of more rapid power change. The proposed rapid maneuvering rates are as follows: 20-85% in 10 to 12 seconds, 100-20% in 3 seconds. These rates are considerably faster than those specified in the contract, and the requirements imposed upon the control system are more stringent. As a consequence a more elaborate and costly control system will be required.
