MAPLE: A new multipurpose reactor for national nuclear development in the 1990s

At the heart of a nuclear programme is the research reactor, a very versatile tool that can contribute greatly to a country's scientific and technological development. What most nuclear research institutes, especially in developing countries, currently need is a single, affordable, multipurpose facility that is capable of meeting contemporary programme requirements at a reasonable cost. In recognition of this need, Atomic Energy of Canada Limited (AECL) is developing a new multipurpose research reactor for the 1990s. Available at modest cost, the MAPLE (Multipurpose Applied Physics Lattice Experimental) family of multipurpose reactors features strong neutron fluxes per unit power delivered to a variety of irradiation facilities. MAPLE is designed to operate at thermal power outputs ranging from about one to twenty or more megawatts. The associated reactor technology will be demonstrated at the Chalk River Nuclear Laboratories (CRNL) in MAPLE-X, a 20 MW version optimized for radioisotope production. MAPLE-X will be placed in service in mid-1988. Moreover, countries now requiring a versatile multipurpose reactor will be able to participate fully with the AECL development team in realizing MAPLE facilities that meet their specific programme needs. Through secondments, they will have the additional opportunity to experience the construction, commissioning, and early operation of the MAPLE-X prototype. Furthermore, AECL is in a position to facilitate technology transfer programmes covering the many areas of nuclear science and engineering associated with contemporary uses of research reactors
