1. SCRs control how much of the AC sine wave is allowed to flow through the load. This is done by controlling the phase angle of conduction of either then SCR. This method controls how much of an AC sin wave is allowed to power the load. The effective amount of average power that a partial sine wave has is less than an average of a full sine wave. The result is that the load dissipates less heat because the effective average voltage is lower.

Nuclear reactors produce heat, the heat then is used to make steam, turning turbines. Therefore, the waste of a nuclear power plant is excess steam.
Heat.
The conduction angle in an SCR is the phase angle relative to the power line at which point the gate is fired to commit the anode to conduct to the cathode. By varying the conduction angle, you can change the average power transferred by the SCR.
In a power station, most energy is lost as waste heat during the conversion of fuel into electricity. This waste heat is produced during various processes, including combustion, heat transfer, and friction in the machinery. Efforts to improve energy efficiency in power stations aim to minimize this waste heat and increase the overall efficiency of the system.
thyristor can be scr or triac scr is strictly dc a triac is back to back scr's with a common gate two scr's back to back can be gated independently scrs cost less than triacs an scr can be combined with a full wave bridge to make an equivalent to a triac but this gives an additional 1.5V forward voltage drop
neither is better, it depends on purpose

waste heat is heat that is wasted, like cars waste 75% of heat
After triggering an SCR (Silicon Controlled Rectifier) and removing the gate pulse, the SCR will continue to conduct current as long as the anode current remains above the holding current threshold. Once the current falls below this threshold, the SCR will turn off and stop conducting. This characteristic allows the SCR to be used in various applications, such as in power control and switching circuits.
waste heat recovery boiler is the boiler which takes the waste heat produced by the industries and produce power for example if you take sulfuric plant where the output gas is taken and connected to boiler and power is generated , one of the best manufactures in India is Thermal Systems who is poineer in the Market.for more information you can visit http://www.thermalindia.com/
A Silicon Controlled Rectifier - also known as a thyristor - is a diode with an added terminal whereby, by applying a "control voltage", the diode can be turned "on" but never "off".When supplied with alternating current an SCR or thyristor will always turn off whenever the current falls back to zero in every cycle.For more information see the Related Link shown below.In the case of a computer file, it's the extension type .scr used for a screen saver.
