The gamma-ray component of the reactor radiation field can produce effects which impact strongly upon reactor design, shielding, and safety. Radiation effects arising from the gamma-ray component are induced by interaction of the absolute gamma-ray energy spectrum in the reactor environment. Hence, the most fundamental quantity underlying effects produced by the reactor gamma-ray field is the absolute gamma-ray energy continuum. To this end, the current status of Compton recoil gamma-ray spectrometry in Light Water Reactors (LWR) and Fast Breeder Reactors (FBR) environments is described. Particular emphasis is given to continuous gamma spectometry experiments in a LWR pressure vessel mockup at the Oak Ridge National Laboratory Poolside Critical Assembly (PCA). Gamma spectrometry plans for FBR environments are outlined with special attention placed on start-up experiments in the Fast Test Reactor (FTR). Improvements in Compton recoil gamma-ray spectroscopy are presented.
