University of Massachusetts Lowell Radiation Laboratory

From Wikipedia, the free encyclopedia

The Radiation Laboratory at UMass 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 ray source, and a 5.5 MV Van de Graff accelerator.

[edit] Reactor

First startup was January 2, 1975.[1]

[edit] Facts

Initial cost and annual costs are reported to be $1.2 M and $0.3 M respectively. There are 2 staff and 6 operators. The mas thermal flux is 1.4x1013 and fast flux is 9.2x1012. It has a graphite and water reflector. It is a plate type with 18 plates per element. Cladding material is Aluminum alloy.

[edit] Availability of Information

Unlike the vast majority of university research reactors, the UMass research reactor has no official homepage. In the ABC Primetime special "radioactive roadtrip", it was reported that staff did not respond to emails and a tour could not be arranged but that an archived version of a virtual tour could be found online. This virtual, however, only contains 2 (about 300 pixel wide) small pictures and was pulled from the website in 2002.[2] This is in contrast to other reactors, many of which have large clear pictures of the reactor pool and blue glow of the core on their homepages that are more detailed than what was ever on the Radiation Laboratory site.

In the ABC report, it was also reported that a an officer of the Lowell police force was not aware that the reactor was still in operation at all.[3]

[edit] Conversion to LEU

The UMass Lowell reactor has been one of the many research reactors to make the conversion from high-enriched Uranium to low-enriched Uranium as apart of anti-terrorism security measures.[4] 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.
