NUCLEAR ENGINEERING FOR SAFETY

EVERY LAST DETAIL MATTERS

The goal of engineering is to keep the public safe and never have another accident like these.

HOW OUR RESEARCH PROJECT WAS BORN

NRC contacted Dr. Vierow; Can the tubes in the steam generator rupture during a LOCA?

Research gave them usable data; Dr. Vierow asked a question, What are the events in the surge line of the pressurizer during a LOCA?

DOE funded research to ascertain the conditions under which flooding occurs during countercurrent flow.

A fuel pellet this size has the power of about a ton of coal
