The drop time of the control rod was evaluated based on its weight and the small pressure difference between the moderator (0.3 MPa) and the containment (atmospheric pressure of 0.1 MPa).
In the real-world conditions, control rod channel water inlet temperature is about 40[degrees]C and outlet temperature is around 70[degrees]C.
Criticality calculations of the core with four control rod banks have been carried out.
The control rod assembly has transverse vibration under flow excitation.
The second case is induced by a control rod withdrawal out of core by mistake.
In addition, in order to study the core performance under normal and accident conditions, it is also necessary to investigate the fundamental properties of nuclear reactor core besides the neutron economy analysis, such as moderator and fuel temperature coefficients, control rods worth, radial power distribution, and different void reactivity coefficients.
