This r e p o r t was prepared by Battelle-Northwest under Contract No. AT(45-1)-1830 f o r the Atomic Energy Commission, Division of Reactor Development and Technology, to summarize technical progress made in the Fast Flux Test Facility Program during November 1969.

In phase I tungsten clad cermet fuel specimens were thermal cycled, to study the effects of fuel loading, fuel particle size, stablized fuel, duplex coatings, and fabrication techniques on dimensional stability during thermal cycling. In phase II the best combination of the factors studies in phase I were combined in one specimen for evaluation.

This Systems Study is submitted in accordance with the requirements of AEC Manual Chapter 1801, and proposes the procurement and implementation of a Plant Process Surveillance System for N Reactor. The envisioned system consists of instrumentation, data acquisition equipment, a digital computer, and input/output equipment. It is intended that the system will be a tool for reliable administration of safety limits and standards, simplification of plant operation, and reduction of operating costs by replacing the tasks of shift operations personnel, an instrument technician and a process engineer.
