did it have any government support ?
Yes, the "Einstein–Szilard" letter resulted in the establishment of research into nuclear fission by the U.S. government.
Chicago Pile-1
Szilard drafted a confidential letter to the President, Franklin D. Roosevelt, warning of a German nuclear weapon project, explaining the possibility of nuclear weapons, and encouraging the development of a program that could result in their creation. With the help of Eugene Wigner and Edward Teller, he approached his old friend and collaborator Albert Einstein in August 1939, and convinced him to sign the letter, lending his prestige to the proposal. The Einstein–Szilard letter resulted in the establishment of research into nuclear fission by the U.S. government.
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. 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. the first nuclear reactor you mentioned above where is located ? Stagg Field what was  its significance ? The successful test of CP-1 not only proved that a nuclear reactor was feasible, it demonstrated that the "k" factor was larger than originally thought. It removed the objections to the use of air or water as a coolant rather than expensive helium. It also meant that there was greater latitude in the choice of materials for coolant pipes and control mechanisms. how was it developed ? In August 1941 Fermi began to plan the building of a sub-critical assembly to test with a smaller structure whether a larger one would work. The pile was built in September 1941 from graphite blocks and tinplate iron cans of uranium oxide.

Chicago Pile-1 [SEP] Government support
Szilard drafted a confidential letter to the President, Franklin D. Roosevelt, warning of a German nuclear weapon project, explaining the possibility of nuclear weapons, and encouraging the development of a program that could result in their creation. With the help of Eugene Wigner and Edward Teller, he approached his old friend and collaborator Albert Einstein in August 1939, and convinced him to sign the letter, lending his prestige to the proposal. The Einstein–Szilard letter resulted in the establishment of research into nuclear fission by the U.S. government. An Advisory Committee on Uranium was formed under Lyman J. Briggs, a scientist and the director of the National Bureau of Standards.
