NI Western Branch seminar: BWR Water Chemistry

The lecture is about BWR water chemistry and how it has developed to manage plant issues that have been discovered during development of the BWR design.  The presentation will be by Olivia Collier from Horizon Nuclear Power and Brian Handy from Wood Group and will give some insights to the chemistry regime proposed for the ABWR being built by Horizon at Wylfa Newydd.

The presentation will be at Bristol University School of Chemistry with refreshments from 18:30 for a 19:00 start.

The lecture is free and open to all with no need to pre-register.

This is a Joint Lecture between the Nuclear Institute Western Branch and the Royal Society of Chemistry.

The different types of water reactor have different requirements on their water chemistry regime which enable the operators to control parameters to manage factors such as reactivity and operator doses.
This presentation will give a detailed technical overview of the way in which BWR water chemistry management has evolved to help manage plant issues discovered during operation and development of the BWR, giving some details of the regime to be adopted on the ABWR proposed for Wylfa. The presentation will show how water chemistry has:

• Reduced Stress Corrosion Cracking in the Reactor Vessel
• Reduced Operator Doses in the Turbine Hall and Water Treatment Plant
• Reduced Flow Assisted Corrosion in the Feedwater System
