Among the students attracted by this change was future Cavendish Professor Ernest Rutherford. Whilst Thomson was Cavendish Professor, he discovered the electron and the existence of isotopes, and also fostered an atmosphere of friendliness and mutual helpfulness.

The used HEU fuel was reportedly shipped to the Savannah River Site. The original shipping date was June 2002 but had been postponed many times. As of present-day the shipments have been made and the reactor is in operation with LEU. University of Massachusetts Lowell Radiation Laboratory The Radiation Laboratory at University of Massachusetts Lowell serves the Department of Applied Physics among others. The laboratory contains a 1 MW pool-type nuclear research reactor (UMLRR) that has been operating since 1974, a 300 kCi Co-60 gamma
