It simply cools the water which is circulated through the turbine condenser to condense the steam used to drive the turbine, and which maintains vacuum at the turbine back end to improve efficiency.
It has nothing whatever to do with the nuclear reaction. Photos of nuclear stations invariably show the cooling towers with vapor coming out, perhaps deliberately to make people think this is nuclear pollution. It is simply water vapor and completely safe.
This is to cool the circulating water which cools the turbine condenser and enables the steam leaving the last stage of the turbine to be condensed, as part of the Rankine cycle. The water that flows in the cooling tower is cooled by an updraft of air which is promoted by the shape of the tower, and the updraft accounts for the plume of condensed water vapor seen issuing from the top of the tower. It has absolutely no connection with any radioactivity.
A turbine spins, converting heat into kinetic energy. The turbine rotates an electrical generator which is attached to it. The entire process typically looks like this: 1. In a nuclear reactor core, atomic nuclei are split by carefully controlled neutron particles. This releases a lot of energy, mostly in the form of heat. 2. The heat from the core is used to heat a liquid, the primary fluid. 3. The primary fluid passes through a heat exchanger and passes its heat to a secondary fluid, ordinary water This is done to keep the primary fluid in the reactor containment. 4. The secondary fluid (water) is kept under very high pressure so that it can produce high-temperature steam which is directed through jets aimed at the turbine blades, making the turbine spin. In this way, the heat from the core that has been carried by the primary fluid and secondary steam is converted into kinetic energy. 5. The spinning turbine is attached to an electical generator, which converts the kinetic energy of the spinning turbine to electrical energy. 6. The electrical energy is carried by wires to a transformer network which sends it into the distribution grid, where it is carried to users. In a ship or submarine, it is possible to connect the turbine to both an electrical generator and a torque converter (think "automatic transmission"), so that the turbine can drive the propellers directly while the generator is producing electricity. This eliminates the losses of using electric motors to turn the propellers. It is also possible to use separate turbines for propulsion and electrical generation.
Power station cooling towers can be used on nuclear and coal fired power plants, there is no difference, and on a nuclear plant there is no connection between the cooling tower and the nuclear reactors. They are simply used to cool the water flow which itself is used to condense the steam exiting from the steam turbine. In the turbine condenser there are tubes that the cooling tower water flows through so it is separated from the steam/water which is used to actually drive the turbine. In the cooling tower itself, at least the most common hyperboloid shaped ones, the water to be cooled is sprayed downwards against the up draught of cooling air, and the cooled water is collected in a lower pool, to be returned to the cooling circuit pump suction. The air up draught occurs naturally as it is warmed by the downcoming warm water, and it carries some water vapour up to the tower top, which is why we see a plume of condensed water vapour coming out of the towers. This is nothing whatever to do with any nuclear process or any flue gas discharge on a coal fired station. Cooling towers can also be forced draught with fans to blow the air through, but these are not usually used on power plants.
They dispose of waste process heat, without putting it in rivers.
Specifically the main process in an oil refinery is fractional distillation, which involves heating the crude oil then condensing it out on a series of collection "shelves" inside a fractionation tower. The lower shelves are quite hot and the temperature is reduced on each successive shelf up the tower in a very precise controlled manner all the way to the top where the shelves are well below room temperature. A large amount of heat must be removed from these towers to maintain this temperature profile, so that they can consistently separate all the fractions in the crude oil.
A cooling water condenser at a nuclear power plant condenses steam created when colling the nuclear fuel, permitting the water involved to be used in a closed loop system.
Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere. To treat water, they use Pulsed Technology, Ultrasonic Algea and biofilm control.

Rejected to the turbine cooling system, but this is the same in any power plant running on the Rankine cycle, whether nuclear or fossil fuelled
How is a nuclear power plant safe?
According to Wikipedia's sources, the power plant in Palatka, Seminole Generating Station, is a coal burning power plant. It only appears to be nuclear because of the cooling towers that are iconic of nuclear power plants but can be used coal fired power plants. I would have to imagine that the blast from a coal power plant, if exploded, would not travel the 40 or so miles to Ocala.
Yes, nuclear power plant can be shut down.
The nuclear reaction used in the Bataan power plant is nuclear fission.
The power plant were where they were because the generators needed cool water for the cooling systems at the plant.

Salinity points? In coastal plants using sea water cooling, a leak in the turbine condenser can allow sea water to enter the secondary water, as the secondary side is under vacuum in the condenser. Is this what you have in mind?
A nuclear power plant needs a large heatsink, i.e. cooling water. There is very little cooling water in the middle of a desert. That is why nuclear power plants are generally built on the edge of oceans or lakes, or on large rivers.
The nuclear power plant is used in the following way:nuclear fission occur in the nuclear fuel producing heat energythe energy is transferred to the coolant producing steamthe steam spins turbines that moves the electric generator and thus producing electricity.the steam out of the turbines turns to water in the condenser and returns back to be heated again into steam and so on.the condenser gets its cooling water from the ultimate heat sink that could be sea. ocean, river, lakes, ...etc

Nuclear power plants need to be near an ocean, a major river, or a lake, because they need a source of cooling water. This cooling water is used to condense steam back to water to continue the nuclear steam supply cycle, and to remove residual heat from the power plant.
Many major components of thermal power plants are designed for a service lifetime of about thirty to fifty years. The actual condenser lifetime will depend on a number of factors: quality of materials, impurities in the cooling water, whether the plant is run continuously, etc. From time to time, some of the tubes of the condenser may need to be replaced as one aspect of the periodic maintenance of the plant.
