To study the influence of parameter uncertainties of helical coil once-through tube steam generator (HCOTSG) on the operation of small pressurized water reactor, based on the establishment of the core power control system, the feed water control system of steam generator and the pressure and water level control system of pressurizer a quantitative platform for parameter uncertainties of HCOTSG on the small pressurized water reactor was developed. Taking the uncertainty quantification of inner and outer diameters of helical pipes as an example, ...
