Supporting the Systems
Improving Nuclear Plant Safety
Design Safety Group Starts Experiment with UNM
A new effort underway between Los Alamos National Laboratory and the University of New Mexico will help nuclear power plants improve their safety plans and designs.
The project, sponsored by the Nuclear Regulatory Commission, is designed to examine the chemistry that might occur within the thousands of feet of piping within a nuclear power plant. The scientists want to know, in the event of a break in a main cooling water line serving the reactor vessel, would chemical debris be formed that could plug key screens and add to the accident's severity?
Thinking Ahead
Los Alamos Design, Safety and Risk Analysis is the group running the experiments,
and one staffer noted, "If we can understand the chemical reactions that
could occur in such a situation, the Nuclear Regulatory Commission will be
able to make any needed design alterations so that reactors, both those in
use and those in the future, will not be vulnerable."
The Laboratory and University teams have built a grid of pipes and conduit to replicate the reactor setup, and a series of experiments are underway to test the system and analyze the chemistry occurring in such a scenario.
Testing Without Disruption
The advantage of exploring all the "what-if" scenarios is that through advanced
technical tools and hands-on experiments, important scientific and safety
questions can be examined. Without disrupting actual operations in a power
plant, the researchers can point the way to safer operations and design.
