FIELD: research thermal pulse reactors.
SUBSTANCE: proposed nuclear reactor has cylindrical tank of diameter D filled with water moderator and accommodating reactivity modulator incorporating N dry tubes axially and symmetrically disposed over diameter D1 on tank bottom. Dry tubes accommodate movable tubes filled with water, each tube holding two rods made of neutron absorbing material. Rods are rigidly fixed on common hollow shaft at distance R from movable tube axis and at distance 2R from each other. Values of 2R and D1 are found from following expressions: 0.107D > 2R > 0.105D; 0.806D > D1 > 0.8D; protective elements have storage capacitor with spark gaps.
EFFECT: enlarged functional capabilities due to evacuating central test channel in core, reduced neutron background level, enhanced nuclear safety of plant.
