US, 1952 Ivy Mike cryogenic liquid deuterium/tritium test device. The device itself, nicknamed "Sausage", measured 80 inches (2.03 m) in diameter and 244 inches (6.19 m) in height and weighed about 54 tons, its outer steel wall was 10 to 12 inches thick. It contained a triple thermos bottle holding the liquid fuel and a liquid hydrogen circulation system to keep the fuel cold. The device and all its tons of support equipment were on the island of Eugelab in Eniwetok atoll. When Mike was detonated, with a 10.4 megaton yield, the island and all the equipment turned into a crater and a cloud of radioactive fallout. The device was designed by Richard Garwin, at Los Alamos.
The first one small enough to actually fit in an airplane bomb bay was tested in 1954 Castle Romeo, a device named Runt, a emergency version of which entered stockpile later that year as the EC-17 bomb, the next year a ribbon parachute was added to allow the bomber time to escape the blast upgrading it to the MK-17 bomb. The MK-17 was 6 feet diameter and so long only the B-36 bomb bay was big enough to hold it. The MK-17 went through 2 upgrade mods (MK-17 mod-1 and MK-17 mod-2). Changes to the fission primary of the MK-17 produced the MK-24 with the same dimensions. The MK-24 also went through 2 upgrade mods (MK-24 mod-1 and MK-24 mod-2). Both the MK-17 and MK-24 were retired from stockpile sometime between 1958 and 1961, as smaller lighter weight bombs were developed that other bombers and even fighters could deliver.

It was not built at any university, although work for the Manhattan Project on various parts of it were done at several universities across the US. Actual design and assembly of the bomb was at Los Alamos, NM; the administration of which was assigned to the University of California (but at no time was Los Alamos a university). After the war industrial atomic bomb factories were created; the administration of which was contracted out to various large corporations.
The very first nuclear reactor was Chicago Pile 1. It was built for research and scientific use. The first nuclear reactor outside of a university was built (at Hanford, Washington) primarily to yield plutonium for the atomic bomb destined for Nagasaki, Japan. Nuclear reactors were built primarily for electrical generation beginning in about 1951.
to recover a hydrogen bomb lost off the coast of Spain.
I suggest reading Richard Rhodes books: The Making Of The Atomic Bomb and Dark Sun. They can explain it more clearly than can be done here.
The first power plant was built in Bavarian in 1878
The bomb based on the design by Edward Teller and Stanilaw Ulam was first proposed in 1951, and tested in 1952. The first practical H-bomb (thermonuclear explosive) was built in 1954.
The first hydrogen bomb "Ivy Mike" was tested in 1952.
The hydrogen bomb was first successfully tested in 1952 by the United States.
The first atomic bomb was made in 1945, the first hydrogen bomb was made in 1952.
The first successful hydrogen bomb was detonated (not launched or dropped--it was a 62-ton fixed structure) on November 1, 1952.
Hydrogen bomb gets some of its energy from fusion, uranium or plutonium bomb gets all of it from fission. Either can be more powerful, depending on the design. The most powerful bombs built have all been hydrogen bombs.
The hydrogen bomb was invented by a team of American scientists led by Edward Teller. The first successful test of the hydrogen bomb was conducted by the United States in 1952.
