Trips employing auxiliary trip units include the Loss of Load trip and the APD – High trip. The Loss of Load trip is a contact input from the Electro Hydraulic Control System control oil pressure on each of the four high pressure stop valves. … 10. Loss of Load. The Loss of Load(turbine stop valve(TSV) control oil pressure) trip is anticipatory for the loss of heat removal capabilities of the secondary system following a turbine trip. The Loss of Load trip prevents lifting the pressurizer saftey valves, PORVs and MSSVs in the event of a turbine generator trip. Thus, the trip minimizes the pressure and temperature transients on the reactor by initiating a trip well before reaching the Pressurizer Pressure – High trip and pressurizer safety valve setpoints. The four RPS Loss of Load reactor trip channels receive their input from sensors mounted on the high pressure TSV actuators. Since there are four high pressure TSVs, one actuator per valve and one sensor per actuator, each sensor sends its signal to a different RPS channel. When the turbine trips, control oil is dumped from the high pressure TSVs. When the control oil pressure drops to the appropriate setpoint, a reactor trip signal is generated.  1, record 1, English, - load%20reactor%20trip%20channel

Emergency Electronic Bell Tone System(Alert/Alarm Signal). An emergency electronic alert/alarm bell tone is broadcast over the public address system located throughout the building. Upon activation of a smoke detector, heat detector, water sprinkler flow valve, a manual pull station or the deliberate intervention of the operators within the Building Fire/Safety Control Centre, the electronic bell tone will sound warning occupants of a possible emergency. The bell tone indicates an ALERT or ALARM condition.  1, record 2, English, - emergency%20electronic%20bell%20tone%20system

Les haut-parleurs de l'édifice diffusent également une sonnerie électronique d'alarme ou d'alerte. Dès qu'un détecteur de fumée ou de chaleur est activé, qu'une valve de tête d'extincteur est ouverte, qu'une alarme est manuellement actionnée ou que les opérateurs du Centre de contrôle de l'édifice interviennent volontairement, la sonnerie électronique se déclenche pour avertir les occupants d'une éventuelle situation d'urgence. Le rythme de la sonnerie indique s'il s'agit d'une ALERTE ou d'une ALARME ».  1, record 2, French, - syst%C3%A8me%20d%27avertisseurs%20%C3%A9lectroniques%20d%27urgence
