HWRR应急电源蓄电池极限放电试验

THE DISCHARGE TEST OF THE BATTERY PACKAGE IN HWRR

在HWRR应急电源蓄电池组更换前,模拟HWRR高功率连续运行期间,厂房外电源长期全断电,进行蓄电池组大电流放电试验,直至蓄电池组放电失效,对试验结果进行分析,认为上述事故工况下,蓄电池组容量对应急电源供电有效,能够保证反应堆事故停堆后的应急冷却。

The test has been done for simulating the large current discharge of batterypackage, which may occur at the cut-ofi of mains for long-term while the reac-tor operates continuously at high power level in HWRR. The test was finished onthe aged battery package which was scheduled to be replaced. The test showed thebattery package system used as the. emergency power supply is effective for emer-gency cooling of the reactor core.
