Definitions

  • isolation condenser 310 may have cooling capacity for the entire reactor. That is, isolation condensers 310 and 320 may each be able to condense a full volume of steam produced by an example embodiment lower power reactor to maintain a steady liquid level in the same. Similarly, isolation condensers may have lower and/or varying capacities and be used in any number to provide a margin of safety, such as four total condensers each with a condensing capacity of 75% total core flow for a 3x safety margin.
  • isolation condenser 310 is inadequate, inoperable, or deactivated, pressure in reactor 142 may rise again without any cooling or condensing system, particularly if reactor 142 (FIG. 2) is isolated by isolation valves 200 in the event of a transient. Eventually the pressure will rise to the higher setpoint of fluidic control 166B, which will activate isolation condenser 320 and provide pressure relief and cooling.
  • This setup may be repeated for any number or independently-operable fluidic controls 166 at any number of different, desired pressure setpoints, to provide a throttled and redundant amount of heat removal and condensation to reactor 142.
  • fluidic controls 166 and/or pressure pulse transmitter 167 in example embodiment selective activation and isolation system 165 may also interface with isolation valves 200 that isolate reactor 142 from main feedwater line 120 and/or main steam line 125, in addition to valves associated with isolation condensers 310, 320.
  • Control connections 168 are used to illustrate operative control over the various valves controlling flow to isolation condensers, main steam, feedwater, etc.; it is understood that control connections may be contained in a single body with fluidic controls and manipulated valve or may be an actuator line or other powered connection that opens or closes the valve, for example.
  • fluidic controls 166 and/or pressure pulse transmitter 167 may use control logic to selectively open or close combinations of valves to place a plant in a desired configuration. For example, along with actuation of ICS 300, isolation valves 200 for main feedwater 120 and main steam outlet 125 may be closed to isolate reactor 142 by a single fluidic control 166A or transmitter 167. Or, different fluidic controls 166 may place the plant in differing configurations including triggering a reactor scram and/or main turbine trip, based on worsening detected pressure.
