The advent of modern civilization has boosted the growing human footprint on the earth that is now present throughout the earth, air and sea. In a historical perspective of the world, some of the first objectives of the expansion of the society were reached through the sea itself. Therefore, the role played by the oceans and human activity through them has been vital politically, as well as in trade. Today, modern society also plays a significant part in commerce and has active political interests in the oceans. It has become an established fact that the main industrial trade takes place by the sea route itself compared to the air route. In terms of defense, the major nations of the world have actively developed their naval strengths as defenders, force projectors, starters and defenders. Therefore, the role of an exceptional naval fleet in any nation's defense and trade policy is undeniably critical to the geopolitical success of the country. Today, there are naval forces that are as large as entire cities in the water as they are built for the presence of global power. Undoubtedly, all this activity has huge needs for energy consumption.
In land and air systems the energy needs can be covered by transport to the ground, as well as the base support or medium air support for the air needs, the puzzle comes forward at sea in the energy can decide the result . The operational dynamics of providing energy support at sea is a challenge, since ships may not dock for long periods of time and the support provider can not afford to be abandoned in the middle of nowhere. Initially, some nations responded to this challenge by boosting their naval assets in fossil fuel systems. These worked well for some time, but a growing understanding soon realized that constant replenishment, maintenance, storage limitation and safety were damping factors.
The scientific community of developed nations faced the challenge by identifying the two basic needs of energy support at sea. First, the resource had to be durable and provide enough energy to meet a multitude of operational requirements in both action and peace. Secondly, the resource should have longer replenishment cycles, which would allow a longer range, independence of operation and longer time of availability of naval assets at sea. The only resource that has been able to satisfy all the conditions that also show ease of expansion of accumulated capacities is the option of nuclear energy.
