摘要
压水堆核电机组再热系统采用汽汽换热,与回热系统具有较强的耦合性,因此压水堆核电机组二回路热力计算较为复杂。根据压水堆核电机组二回路热力系统的特点,考虑高压系统汽水损失及辅助汽水流量,建立较为全面的汽水分布矩阵方程,并用于实例计算,计算结果准确。该矩阵方程适用性强,不仅适用该机组的辅助汽水系统改造,对汽水分离再热器疏水去向稍加修正后也适用于其它形式的压水堆机组。
Reheat svstem of PWR nuclear power plant uses steam-steam heat exchange. Because of heat recovery.' system and reheat system with strong coupling, the calcuahion of PWR nuclear power unit thermal system is more complicated than thermal power unit. According to the characteristics of the secondary cirucuit of PWR nuclear power plant, and considering the loss of" high-pressure sys- tems and auxiliary, steam-water, a more comprehensive steam-water distribution matrix equation is established. For the calculatuion example, the result of the calculation is accurate. The matrix equation has a good suitability, which is suitable for reforming the steamwater ssytem of this unit, and it is also suitable for other PWR units.
