Actually Leo Szilard invented both the nuclear reactor and atomic bomb in 1933, applied for a patent covering both in 1934 and was granted that patent (GB630726) in 1936. The British Admiralty (Navy) immediately classified his patent to protect it from the Nazis (and kept it classified until 1949). Szilard however never attempted to build either at the time because no fissionable material was known until it was discovered by a team working in Germany and Sweden discovered that uranium-235 could fission.
Szilard contributed to starting the Manhattan Project by writing the so called "Einstein Letter" the warned FDR that the Nazis might be working on an atomic bomb. (Though called the "Einstein Letter" the only things Einstein did was read the unsigned letter shown him by Szilard, approve what it said, and sign it. Szilard felt it would have more influence on FDR if signed by a much more well known scientist than himself.)
Enrico Fermi only built the nuclear reactor, he did not invent it. Fermi's first nuclear reactor (CP-1 for Chicago Pile #1) first operated on December 2, 1942 (less than a year after the Japanese attack on Pearl Harbor). Fermi almost certainly had access to Szilard's (then classified) patent, but how much he depended on is is unknown.
Note: following the discovery of nuclear fission using uranium-235 in 1939, several people independently and almost simultaneously reinvented the nuclear reactor and/or atomic bomb without any knowledge of Szilard's prior art covered by his patent. At that point it was rather obvious to anyone that understood physics what was required.
Enrico Fermi
The first inventor of a nuclear reactor was Enrico Fermi. Refer to link below.
The nuclear reactor was invented in 1933 by Leo Szilard, in London, but he did not try to build one. The first functioning nuclear reactor, CP-1, was designed and built in 1942 by Enrico Fermi, in Chicago, IL.
Nuclear Science
He was in charge of a team which first demonstrated that a nuclear chain reaction could be produced. This was in December 1942 and was done under the Manhattan Project during WW2, under very secret security at the time, in Chicago. The techniques were applied to the much larger reactors built at Hanford Wa which produced the required plutonium for weapons. None of these reactors produced electricity.

J. Ernest Wilkins, Jr. did not invent the nuclear reactor. The ideas for the nuclear reactor were developed while he was an undergrad at the University of Chicago (though he was brilliant and entered college at age 13).Leó Szilárd and Enrico Fermi are credited with the first nuclear reactor design.

Enrico Fermi did not invent nuclear power, but he was a key figure in early research on nuclear reactions. He conducted his groundbreaking research on nuclear fission at the University of Rome in Italy and later at Columbia University in the United States.
False, but he worked on the project that did.Enrico Fermi created the first nuclear reactor, is true.
