Power System Analysis Continues to Advance Safety, Reliability, Cost-Savings for the Nuclear Industry

ETAP, the leading provider of software solutions for the design, analysis, optimization, and real-time operation of electrical power systems, today announced the release of a report by the ETAP Nuclear Utilities User Group (NUUG), summarizing the collaborative efforts among industry experts to accurately analyze the effects of open-phase faults in electrical networks that result in improved safety and resilience of nuclear facilities worldwide.

This collaboration and the resulting innovation was recognized by the U.S. Nuclear Regulatory Commission (NRC) in a public meeting held in Washington, D.C., as ETAP power system analysis software capability directly aligns with the guidance by NRC's technical document on open-phase fault condition. Both the Institute of Nuclear Power Operations (INPO) and the World Association of Nuclear Operators (WANO) also recognized the importance of this effort and praised the leadership of the ETAP NUUG:

"Accurately identifying the impact of open-phase conditions on a plant distribution system was a significant industry challenge. The prompt, diligent response that the ETAP staff provided the industry - working through their nuclear users group to update and validate the ETAP models - helped to develop the confidence that the analysis results were technically sound. The ETAP staff, working with the user group, is a great example of proactive engagement and response needed to solve a complex issue," said Shawn Simon, Principal Evaluator, INPO.

The Nuclear Energy Institute (NEI (News - Alert)), a policy organization of the commercial nuclear industry, also formed a steering committee and working group of industry experts focused on organizing an industry-wide initiative to address this issue:

"I was particularly impressed when ETAP and their nuclear user group quickly responded to a request by the nuclear industry to address the modeling of a new vulnerability," stated Gordon Clefton, Senior Project Manager, Nuclear Energy Institute. "The dedication of highly skilled programmers to work closely with industry power system experts resulted in a product that will be useful in developing open-phase indication circuitry to maintain the health and safety of the public."

In 2012, the ETAP NUUG community, under the leadership of Technical Chair, Mark Bowman, consulted with ETAP experts to provide a capability in the software to simulate and analyze the effects of an open-phase condition. After close collaboration and an interactive customer-vendor development effort, in 2014 ETAP unveiled an enhancement to its Unbalanced Load Flow module that provided a comprehensive graphical Open-Phase Fault Analysis (OPFA) capability to study the condition and, in turn, saved utilities millions of dollars that would have been required by alternative approaches.

"Tackling complex and cutting-edge power system challenges are what ETAP's Thinking Power is all about," said Dr. Farrokh Shokooh, President and CEO of ETAP. "Throughout our history, we've sought out the most rigorous engineering hurdles, not because they would sell the most software, or bring in the most revenue, but because they helped our customers in ways that were instrumental to achieving their operational and business goals. We are very proud of the ETAP spirit, and the way it powers our customers' success."

ETAP would like to recognize the dedication and leadership of the ETAP NUUG Open-Phase Task Force and the team of power system analysis experts from Duke Energy (News - Alert), Enercon Services, Inc., Exelon Corp., MPR Associates, Inc., Sargent & Lundy, LLC, Southern Nuclear, and Tennessee Valley Authority (TVA).
