The Imperial College (IC) research? reactor was designed jointly by GEC and
the IC Mechanical Engineering Department. It first,vent critical on 9 Apri
l 1965 and has been operating successfully fbr over 33 years. The reactor p
rovides a service to both academia and industry for neutron on activation a
nalysis, reactor and applied nuclear physics training, neutron detector cal
ibration, isotope production and irradiations. The reactor has strategic im
portance for the UK, as it is now the only remaining, research reactor in t
he country. It is therefore important to put in place refurbishment program
mes and to maintain and upgrade the safety case. This paper describes the c
urrent facilities, applications and users of the research reactor and outli
nes both the recent and the planned developments.
