Where can i find more information about new nuclear plant start-up procedures?
Which new plants? Considering the new generation of LWRs will be operated more or less as are the older generation, the startup procedures will be much the same. How much detail does one expect? Is this related to power plant commissiong or a general startup following a refueling outage?Where can i find more information about new nuclear plant start-up procedures?
C.3. The testing of SSCs should include, to the extent practical, simulation of the effects of control system and equipment failures or malfunctions that could reasonably be expected to occur during the plant’s lifetime. The test program should also include testing to determine that the system and component interactions are in accordance with design. To the extent practical, the plant conditions during the tests should simulate the actual operating and emergency conditions to which the SSCs may be subjected. To the extent practical, the duration of the tests should be sufficient to permit equipment to reach its normal equilibrium conditions (e.g., temperatures and pressures) and, thus, decrease the probability that failures, including “run-in” type failures, will occur during plant operation.
In the initial heat up, the reactor system is given time to heat up for cold zero power (CZP) to hot zero power (HZP) and at the same time the system is pressurized. [/url]
Reactor Recirculation Pumps impart energy into the reactor coolant that eventually turns into heat.
Startup from cold, the primary circuit pumps are run to heat up the primary system. Depending on the capacity of the primary system, the pumps may add on the order of 5 MW per pump. This heats up the primary system and reactor. The pressurizer has a heater, but this is really to maintain heat on the pressurizer to ensure the primary circuit pressure is maintained in the operational range.How Does the first heat up achieved? I assume reactor is shut down so there is no heat generation from fission. Is there an electrical heating system involved?
Here's an example from the UK.They do this test, before fueling the reactor? How long does it take to to go from Cold zero power to hot zero power? where do they bring power to run the pumps? Do you know how much power in terms of Watt requires to run the recirculation pumps?
