System and Methods for Optimizing Availability and Performance of Light Water Reactors

More than a quarter of the world's carbon dioxide emissions come from burning fossil fuels to produce heat and electricity. Nuclear energy plants do not emit criteria pollutants or greenhouse gases when they generate electricity. Thermal-neutron reactors are the most common type of nuclear reactor, and light water reactors (LWRs) are the most common type of thermal-neutron reactor, which uses normal water as the primary coolant. Localized corrosion in the primary coolant circuits (PCC) is a big problem in LWRs. The rate of corrosion is often determined by certain electrochemical properties, such as the electrochemical corrosion potential (ECP), solution conductivity, temperature, pH, flow rate, and the kinetics of the reduction of a cathodic depolarizer (e.g. O2) on the surfaces external to the crack. Mechanical loading (stress intensity factor on the crack) and micro-structural/micro-chemical factors (e.g. grain size, precipitates, degree of sensitization) may also contribute to this problem. To address this problem, researchers at the University of California, Berkeley, have developed an operating protocol in which the PCC are protected over wide ranges of parameters as the reactor progresses through a fuel cycle, including: temperature, pH, ECP, solution conductivity, flow rate, and stress intensity factor. Laboratory models using Berkeley approach suggest significant LWR optimization while adding levels of safety and lowering operational costs (e.g., by avoiding primary water stress corrosion cracking in Alloy 600 steam generator tubes, which is a major corrosion phenomena in operating a PWR). In fact, Berkeley’s solutions require minimal modification to the reactor PCC, and in most cases, can be implemented with no modifications at all.

A Novel, Eco-Friendly Continuous Flow Intersection

Background: Traffic signals at traditional intersections impede traffic flow thereby increasing harmful emissions, travel time and fuel/energy consumption. With over 250 million vehicles on the road, many municipalities are seeking novel ways to improve the current intersection design to be eco-friendly and safe for both drivers and pedestrians, while remaining efficient.   Brief Description: Unconventional Arterial Intersection Design (UAID) is the science and art of designing traffic intersections to improve mobility and safety. UCR researchers have designed the first real continuous flow intersection. This novel design allows drivers to maintain their speed throughout the intersection and get from point A to B without stopping. As a result, it increases traffic capacity and land utilization while decreasing travel time and the likelihood of accidents. They have also implemented a novel pedestrian passageway that protects pedestrians from vehicles and direct exhaust emissions.
