Conclusions

Our results show that the MR-3 heterogeneous reactivity modulator, made of ÉI-437 nickel alloy, makes it possible to reduce the power pulse length of the IBR-2 reactor from the present 215 μsec to 115±5 μsec without changing the rotational speed of the primary reflector (1500 rpm), but with an increase in the rotational speed of the secondary reflector to 1200 rpm. At a rotational speed of 300 rpm for the secondary reflector, the pulse length will be 130±5 μsec. For the steel version of the MR-3 these values of the pulse half-width increase to 170 and 190 μsec, respectively.

For a length of 115 μsec, the amplitude of the principal power peak is 2700 MW (average power is 2 MW). The first secondary power burst due to the multiplication of delayed neutrons has an amplitude of 3.2 MW and a length of 320 μsec at the level of the adjacent power minimum, and appears 600 μsec earlier than the primary burst. The second secondary pulse with an amplitude of 3.7 MW and a length of 240 μsec appears 430 μsec after the primary burst. The power of the reactor with the reflectors withdrawn (the background power) is 0.14 MW. The operation of the IBR-2 with the MR-3 modulator is designed for a burst repetition rate of 5 Hz.
