Application of the sensitivity and uncertainty analysis system LASS to fusion reactor nucleonics
Abstract
The primary output from the sensitivity system LASS is the uncertainty (or change) in important reactor parameters. Applications of LASS and its component parts were made to the Tokamak Fusion Test Reactor the Reference Theta-Pinch Reactor, and to an Experimental Power Reactor (EPR). This paper emphasizes the initial assessment of cross-section sensitivity for an EPR design. Nucleonic responses examined include neutron and gamma-ray kerma in the toroidal field coils and Mylar superinsulatoroidal field coils, and activation of the outboard dewar. Experience at LASL with sensitivity and uncertainty analysis techniques incorporated in LASS has provided convincing evidence of their value for fusion studies. Many of these studies are of a shielding nature; e.g., deep penetrations of high-energy neutrons through stee, lead, boron carbide, and graphite, with responses such as activation and kerma.
