MUTR History

An early image of the core of the reactor while it was being constructed. The script to the right of the picture reads, "(WX10) COLLEGE PARK, MD., AUG.26 -- NUCLEAR REACTOR AT MARYLAND U.--A new "swimming pool" nuclear reactor was shown for the first time today to newsmen at a University of Maryland news conference. Prof.Dick Duffy, left, reactor director and professor of chemical engineering, and associate professor Joseph Silverman, Duffy's assistant on the reactor project, check the mechanism which is scheduled to become operative in the fall. The 240-ton concrete and aluminum device, standing more than two stories high and some 20 feet thick at the base will be used by students of nuclear engineering at..."

The reactor pool being filled with water.

"This is an artist's conception of the new nuclear reactor, the first in the State, at the University of Maryland. The device has been bought by the Department of Chemical Engineering for training graduate and undergraduate students under Atomic Energy Commission scholastic grants." December 1st, 1959.

Caption originally read, "University of Maryland president, Wilson H. Elkins, left, reviews the logbook of the school's nuclear reactor with professor Dick Duffey, director of the facility. The university has asked the Atomic Energy Commision for a cyclotron to further its growing program of nuclear research. Russell B. Allen, assistant dean of the college of engineering, looks down from the reactor bridge. Ernest Loeb, project engineer, is seated at the reactor console in the rear." January 27th, 1961.

A group tours the reactor console room with former facilities director Professor Silverman (light gray suit, center). 

An early chart recorder displaying what is possibly the power reading from the compensated ion chamber and the fission chamber.

The same chart recorder. The chart is showing the ramp up of the reactor from the 10 mW range to the 30 mW range.

Visitors to the reactor being shown the control rod drive mechanisms.


An early configuration of the core of the reactor.

The reactor console room. The unit to the left remains in the console room today, whereas the teletext machine has since been removed.

Visitors looking down into the reactor pool.

A view of the rabbit system (two tubes in the center) and the instrumented fuel rod (slight left of center). The core can be seen further down.

Visitors on top of the 21 ft atomic reactor. January 27th, 1961.
