Second, a large volume in the core provided very flexible capabilities for thermal neutron irradiation, and third, a large opening was left in the reactor tank for placement of a "cold source," which would later become the basis of the Cold Neutron Research Facility (CNRF).
These improvements, combined with the opening in 1990 of the cold neutron research facility, with instrument developments continuing through the 1990s, made the NBS reactor facility (now called the NIST Center for Neutron Research, NCNR) the most heavily utilized neutron center in the United States.
When the Cold Neutron Research Facility becam operational in late 1990, the first measurement made the guide hall was by PGAA.
