Abstract
The HIFAR reactor loaded with a core of 150 g Mark III fuel elements was simulated using the PACE analogue computer to assess expected power transients following positive reactivity additions. If five coarse control arms operate, and the operational power is 85% of the trip level, the power transient from an initial 15 MW will not exceed 30 MW if the rate of addition of reactivity does not exceed 0.535% k/k per second, or a step addition does not exceed 0.342 k/k. The peak power attained is influenced by the delay in releasing, and by the initial setting of, the coarse control arms.
