Embodiment

[0024] like Figures 1 to 2 As shown, the thermal-hydraulic comprehensive performance simulator of the special safety system of the reactor of the present invention includes a coolant experimental system, a steam condensation system, a passive safety injection and waste heat discharge experimental system, and a recirculation experimental system for coolant simulation experiments. , pressure relief experimental system, loss of water accident experimental system, power supply system, and thermal parameter acquisition and control system, coolant experimental system, steam condensation system, DC power supply system and thermal parameter acquisition and control system to complete the normal operation of the simulated reactor Nuclear heat release process, coolant forced circulation flow, pressure control adjustment and steam output; passive safety injection and waste heat discharge experimental system, coolant experimental system, steam condensation system, DC power supply system an...

Embodiment approach

[0026] The first method: through the inlet quick-release pipeline 602 and the outlet quick-release pipeline 603 in the loss of water accident experimental system respectively connecting the pipeline 605 and the pipeline 606 to realize the experimental simulation of the whole transient process of the direct injection pipeline when the loss of water accident occurs.

[0027] First, the coolant experiment system, steam condensation system, DC power supply system and thermal parameter acquisition and control system jointly complete the nuclear heat release process, coolant forced circulation flow, pressure control adjustment and steam output during the normal operation of the simulated reactor.

[0028] Then the thermal parameter acquisition and control system outputs the control signal of the loss of water accident, controls the DC power supply system to change according to the decay heat curve, the main pump 109 gradually stops running according to the emergency shutdown situation...

Abstract

The invention discloses a thermal-hydraulic comprehensive performance simulator specially designed for a reactor safety system, including a coolant experiment system for coolant simulation experiments, a steam condensation system, a passive safety injection and waste heat discharge experiment system, a recirculation experiment system, Pressure relief experiment system, water loss accident experiment system, power supply system, and thermal parameter acquisition and control system. The present invention realizes the continuous experimental research of the whole process of seven stages from high-power normal operation state, full-pressure breach discharge, high-pressure injection, system pressure relief, medium-pressure safety injection, low-pressure injection to the establishment of long-term natural circulation under low pressure , from the high-power normal operation state to the power outage stage of the whole plant, the continuous experimental research of establishing the passive waste heat removal system until 72 hours after the accident has been realized. Equipped with a safety system, the device has good adjustability and controllability, and the adjustability and controllability of the simulated accident sequence are excellent.

Description

technical field [0001] The invention relates to the experimental field of thermal and hydraulic comprehensive performance of the new reactor special safety system, which relates to the passive dynamic steady-state characteristics and transient characteristics of the new reactor in the state of dehydration accident and the power failure state of the whole plant, and specifically relates to the design of reactor safety System thermal-hydraulic comprehensive performance simulator. Background technique [0002] With the continuous advancement of reactor research and development technology, the requirements for its safety are getting higher and higher. New reactors introduce passive technology into the design of the special safety system. The safety system is designed to respond immediately, avoiding human intervention and improving the inherent safety of the reactor. This passive technology is used in the design of the reactor safety system. After the accident, the height diffe...
