The laboratory was based on the neutron fast-pulse reactor ( IBR ) then under construction at the site.
2.
The site has a neutron fast-pulse reactor ( 1500MW pulse ) with nineteen associated instruments receiving neutron beams.
3.
With the exception of experimental pulsed reactors, nuclear reactors are designed to operate in a delayed-critical mode and are provided with safety systems to prevent them from ever achieving prompt criticality.
4.
Godiva's success in creating intense bursts spurred development of similar pulsed reactors, which also suffered accidental excursions, for example : 28 May 1965 at the 1965 White Sands Missile Range ( parts were thrown 15 feet ); and 6 September 1968 at the Aberdeen Proving Ground ( middle melted, disks warped and bolts stretched ).
