Current and projected techniques for using Solid State Track Recorders (SSTR) and Nuclear Research Emulsions (NRE) for the measurement of various nuclear parameters in Fast Breeder Reactor (FBR), Light Water Reactor (LWR), and Magnetic Fusion Energy Reactor (MFER) programs will be presented. Two categories of SSTR, one for fission fragment detection and the other for alpha particle detection, are of importance in reactor applications. Etching, annealing, and track read out techniques are discussed. For FBR programs, SSTR for fission fragments are used together with various fissionable isotopes to provide information on neutron fluence and fission rates at in-core and out-of-core locations. Fission rates coupled with radiochemical, gamma spectrometry, and mass spectrometry techniques provide measurements of absolute fission yields and capture to fission ratios. SSTR for alpha particles also offer promise for the measurement of alpha particle production from /sup 10/B, /sup 6/Li, and other nuclides. SSTR for fission fragments and alpha particles will be used for Pressure Vessel Surveillance (PVS) in the LWR program to give information on neutron fluence-spectra. The use of SSTR for neutron fluence, helium production, Primary Knock-on Atom (PKA) observations, and tritium breeding measurements are also projected for the MFER program. NRE provide information on neutron spectra, including angular anisotropies. Three specific interactions, n-p scattering, /sup 6/Li(n,t)/sup 4/He, and /sup 10/B(n,t2..cap alpha..) are discussed in terms of the specific kinds of information each can provide for the FBR, LWR, and MFER programs.
