This report describes unusual health physics problems, such as shielding modifications required, encountered with start-up and operation of the Sandia pulsed reactor. Included are: integral radiation doses received from primary and scattered neutron radiation; gamma radiation doses resulting from fission products in the reactor itself; and neutron induced radioactivities in the air, walls, and floor of the reactor building. Also listed are present health physics procedures and personnel dose histories.

The Sandia Pulsed Reactor Facility (SPRF) is a laboratory facility specifically designed for radiation effects experiments which require an intense pulse of fast neutrons and gamma rays.
