out from reaction reactor core passes to secondary circuits water, makes that produce
qualified steam driving the steam turbine acting. The person designs, safety runs analysis
as heat transfer equipment to be unable to be seprated from the hot labor calculating
analysis studying, the quantity of heat between primary circuit coolant and secondary
circuit exchanges is to be in progress in the process of flow, not only these flow affecting
heat exchange process but also economy and reliability, therefore Hydrodynamics problem
also becomes a steam generator designing the important problem thinking. In this work
combining with actual project background , the basis in steam generator physical design,
heating power calculation and water driving force is secretly schemed against analyzing
combining with being in progress each other, studying reaches verification and
improvement designing a parameter. For million steps of nuclear power plant steam
generators act on self's own, design provides a reference.
Firstly, under premise grasping such as functional classification, working medium
technological process, structure module to the steam generator, the analysis being in
progress to present in connection with steam generator thermal hydraulic computation
method rationale chooses.
Secondly, specifically for 300,000 KW of Qin Shan nuclear power plant steam
generators, under primary side import and export temperature pressure is certain situation,
the analysis carrying out the steady state thermal hydraulic computation studies, Secretly
scheme against analytical different power level lower steam generator, to nothing dirt and
nothing mssingle new steam generator state, and to have dirt and mssingle amounts
reach 10% state, reach steam generator outlet steam pressure, primary side and secondary
side circuit coefficient of heat transfer, repeated side circulation multiplying power,
repeated side water dress amounts and so on hot labor parameter. Analysis provides the
reliable basis to engineering design, improvement and safety. And get a set of method and
procedure that the simple, reliable mature, suitable entire engineering design in the steam
generator calculates.
Thirdly, run the thermal parameter according to Qin Shan nuclear power plant reality
stack , the labor carrying out heat checks the analysis secretly scheming against , the
