This question presupposes the existence of an antimatter reactor. As far as I know, no such reactor exists, or has even been designed.
Antimatter reacts with matter to produce energy with virtually no matter remaining. Such a reaction is thousands of times more powerful as nuclear reactions we have used on this planet.
But antimatter is difficult to make and nearly impossible to handle. As soon as it touches anything, it is gone.
There is a lovely quote from a researcher who has made antimatter often. He said that if all the antimatter made at CERN were put together and reacted with matter, the resulting energy would power a light bulb for a few seconds. This even though it is the most powerful reaction we know of.
There just is not enough of it to react usefully.
You can work out the gas flow from the gas circulator characteristics, and measure the reactor inlet and outlet temperatures, so you can work out the reactor thermal output. Then you can measure the thermal conditions in the steam circuit from feed flow and temperature and steam temperature and pressure, this will give the reactor thermal output together with the gas circulator heat input. From all this data work out the best estimate for the reactor output. The generator output is straightforward, then you have to subtract the power being used on the plant for driving the gas circulators and feed pumps etc, to get the net electrical output, then it is just the ratio of that to the reactor thermal output.
Lowering control rods into a nuclear reactor will absorb neutrons, reducing the rate of fission reactions and therefore decreasing the reactor's power output. This is a common method used to control and regulate the reactor's power level.
The void coefficient in nuclear reactor safety measures how the reactor responds to the formation of steam bubbles (voids) in the coolant. A positive void coefficient means that as more voids form, the reactor's power output increases, potentially leading to a runaway reaction. A negative void coefficient helps stabilize the reactor by reducing power output as voids form, improving safety.
The power output of a nuclear reactor can vary widely, depending on the design and size of the reactor. Commercial nuclear power reactors typically have power outputs ranging from 500 megawatts (MW) to over 1,500 MW.
A positive void coefficient in a nuclear reactor means that as coolant (water) turns into steam, the reactor's power output increases. This can lead to a rapid increase in reactor power, potentially causing overheating and a meltdown. It is a safety concern because it can make the reactor more prone to accidents and harder to control.
The typical output power of a boiling water reactor (BWR) is around 1000-1400 megawatts thermal (MWth), which translates to approximately 350-450 megawatts electric (MWe) of generated electricity. This output power may vary depending on the specific design and size of the BWR.

The thermal output of a nuclear reactor is usually quoted in Megawatts(th) to distinguish it from the electrical power output in MWe. For a large PWR of output 1500 MWe, the thermal output of the reactor will be about 4500 MWth. Now 1 calorie = 4.2 Joules, so this power represents 1070 x 106 calories/sec
MWe and MWt are units for measuring the output of a power plant. MWe means megawatts of electrical output, and MWt means megawatts of thermal output. For example, a nuclear power plant might use a fission reactor to generate heat (thermal output) which creates steam to drive a turbine to generate electricity (electrical output). A reactor that generates 200 MWt (50 MWe), and another reactor that generates 800 MWt (200 MWe).
A positive void coefficient in a nuclear reactor means that as coolant (water) turns into steam, the reactor's power output increases. This can lead to a rapid increase in reactor power, potentially causing overheating and a meltdown. It is a safety concern because it can make the reactor more prone to accidents and harder to control.
The efficiency of a PWR or BWR reactor power plant is about 33 percent, so this means that about 67 percent of the reactor's thermal output is rejected to the cooling water
In a nuclear reactor, lowering control rods will result in the absorption of more neutrons, which slows down the nuclear chain reaction. This leads to a decrease in the reactor's power output or can even shut down the reactor completely.
Lowering control rods in a nuclear reactor will result in the absorption of neutrons, which decreases the rate of fission reactions happening in the reactor core. This leads to a decrease in heat production and ultimately reduces the power output of the reactor.
The power required to start a nuclear reactor varies depending on the size and type of reactor, but typically ranges from a few hundred megawatts to several gigawatts. Once the reactor is operating, it generally requires a smaller amount of power to maintain criticality and sustain the fission chain reaction, usually around 1-5% of the total reactor power output.
