how is the waste disposed off ?
There are no commercial scale purpose built underground high-level waste repositories in operation. Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate.

Presently, waste is mainly stored at individual reactor sites and there are over 430 locations around the world where radioactive material continues to accumulate.
Some experts suggest that centralized underground repositories which are well-managed, guarded, and monitored, would be a vast improvement.
There is an "international consensus on the advisability of storing nuclear waste in deep geological repositories", with the lack of movement of nuclear waste in the 2 billion year old natural nuclear fission reactors in Oklo, Gabon being cited as "a source of essential information today."

There are no commercial scale purpose built underground high-level waste repositories in operation. 
where can the resource for nuclear energy be found It is produced by nuclear fission of uranium and plutonium. what is nuclear power ? It is the use of nuclear reactions that release nuclear energy to generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant. which was the first nuclear reactor ? Chicago Pile-1 does this power produce any waste ? Yes, spent nuclear fuel is the waste generated. what are different types of waste ? Low-level radioactive waste, is one type of nuclear waste. It is found in the form of contaminated items like clothing, hand tools, water purifier resins, and the materials of which the reactor itself is built. what is nuclear fusion ? It is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions.

Nuclear power [SEP] Waste disposal
However, in Finland the Onkalo spent nuclear fuel repository is under construction as of 2015. The Waste Isolation Pilot Plant (WIPP) in New Mexico has been taking nuclear waste since 1999 from production reactors, but as the name suggests is a research and development facility. In 2014 a radiation leak caused by violations in the use of chemically reactive packaging brought renewed attention to the need for quality control management, along with some initial calls for more R&D into the alternative methods of disposal for radioactive waste and spent fuel. In 2017, the facility was formally reopened after three years of investigation and cleanup, with the resumption of new storage taking place later that year.
