| 101 | Emergency feedwater system for steam generators of a nuclear power plant | US596879 | 1984-04-05 | US4654190A | 1987-03-31 | James S. Schlonski |
| An emergency feedwater system for the steam generators of a pressurized water nuclear reactor has two separately located subsystems, each subsystem supplying water to at least one steam generator when activated, where each subsystem contains an emergency feedwater supply tank, and a pair of emergency feedwater lines leading from the tank which communicate with the inlet line of a steam generator. An electrical operated motor driven pump is located in one of said pair of emergency feedwater lines and a steam turbine driven pump in the other of said pair, with a cavitating venturi provided in an emergency feedwater line between the pump and inlet line of the steam generator. The system is adaptable for use with two, three, and four loop pressurized water reactor systems. | ||||||

| The control of the actual liquid level in a boiler is accomplished by using the actual enthalpy of the fluid in the boiler to generate a signal which is utilized to bias the output from a conventional level controller in such a manner that swell and shrink causes by disturbances is compensated for and a desired liquid level is maintained in the boiler. | ||||||

| A line is connected to a branch point between the gas-heated preheater and evaporator to deliver heated feed water to the supply tank while control valves are placed in the feed line to the preheater and the line to the supply tank. These valves are controlled by a temperature measuring means adjacent the branch point. If the measured temperature increases, the flow of feed water to the preheater increases. | ||||||

| PURPOSE:To keep the fluctuation of supply water flow rate at pump switching to a constant range in excellent ways rapidly, by changing the speed of increase/ decrease of the water supply amount shared with water supply pumps in response to the deviation between supply demanded amount and actual supplied amount. CONSTITUTION:The deviation between a boiler water supply flow rate demanding signal 30 and a boiler water supply flow rate signal 8 is calculated by a calculator 32, the deviation is processed at a function generator 22 having a dead band up to a value (b) at the vicinity of the permissible water supply deviation and summed with a changing rate 24 of a program set signal by an adder 23. A program set signal 12 is outputted by integrating this signal by an integrator 21. In switching a changeover relay 11 of a pump A, the amount of supply flow of the pump A is increased and that of a pump B is decreased. In this circuit, if the boiler water supply deviation exceeds the value (b) close to the permissible value, the rate of change of the program set signal 12 is decreased automatically, so as to control the water supply deviation to be the permissible value. | ||||||

| PURPOSE:To compensate the effect due to the adverse response properties of the water level of a drum, by providing a load variation degree differential element to suppress the water supply command signal by an amount equivalent to the differential element. CONSTITUTION:A differential element 13 receives the signal corresponding to the load quantity of electric energy, steam flow rate, buring command value, fuel flow rate, etc., and differentiates the signal, multiplies the value of differentiation by a differential time constant and transmits the signal to a subtraction element 14 in the form of a feed forward control signal. The element 14 subtracts the output value of the element 13 from the output value of a water level regulator 11 to deliver a command value (g) for water supply quantity. | ||||||
