The time behaviors of the neutron fluxes at various points in the swimming pool type reactor core after pulsed neutron injection were obtained by an analog computer in the two-group diffusion approach.The neutron multiplication propagates from the source through the multiplying medium, and the velocity of the propagation depends on the size of the system. The neutron flux distribution should be the steady one at certain time after the pulsed neutron injection. The propagation time amounts to several hundreds microseconds in some cases close to the critical. Therefore, the very short pulse operation could never be performed for large core close to the critical.
