Speech Title: An Engineerˇs Journey in Nuclear Energy
Speaker Name: Lo Wu
Education: BS, M. Arch.
Affiliation: Exelon Nuclear
Frank and honest sharing from an engineer who has worked in the nuclear power industry for more than thirty years in the United States is the main theme of this speech.
Mr. Lo Wu, a native of Taiwan, has been working in the US nuclear power industry since 1981. He started as an engineering analyst at Nutech Inc for the Mark-I piping analysis. During the early 80s, following the Three Mile Island (TMI) nuclear power plant event, US power industry was tasked to quickly to have all those GEˇs Mark-I Torus structures and piping reanalyzed to account for the then newly identified torus hydrodynamic inertia loads. It should be noted that TaiPowˇs Chin-Shun nuclear station was one of the plants that had been reanalyzed by Nutech for the Mark-I Torus loads. Mr. Wu subsequently worked at Bechtel for the containment steel structural reanalysis of the Diablo Canyon nuclear plant and later for Byron/Braidwood nuclear plants project at Sargent & Lundy. In 1995, Mr. Wu joined Exelon Nuclear, the largest utility company in the US, as an on-site supporting Senior Engineer at Dresden nuclear station and has been working as a Senior Staff Engineer in Dresdenˇs Engineering Department since 2008.
There have been many challenges in the US nuclear power industry during the last two decades of the 20th century: plant scrams, challenges to safety systems, regulatory challenges, weaknesses in on-site engineering, and weaknesses in refuel outage execution. Mr. Wu witnessed the changes starting from the mid 1990 and into 2011. His work station, Dresden nuclear power plant, was once on the Nuclear Regulatory Commission (NRC) ¨watch listˇ and on the verge of shutting down. It has since then transformed into an ¨INPO 1〃 plant. He saw leadership, equipment reliability, and standards and expectations changes and improvements. He observed the complete turn around of the Dresden nuclear station. Both Dresden units 2 & 3 have been in commercial operation since 1970 and 1971 and their 40 year operating licenses were due to expire. In October of 2004, the NRC renewed the operating licenses for both units for an additional 20 years, extending them to 2029 and 2031. Both units contain boiling water reactors (BWR) designed by General Electric. Each unit is capable of generating over 912 net megawatts of electricity, which together can produce enough power to support the electricity needs of over 1 million average American homes.
Mr. Wu is sharing with us the success of the Dresden nuclear stationˇs rise in superior performance with his in-depth insider information. He is completely convinced that nuclear energy is an acceptable alternative source to many renewable energies that are economical and environmental acceptable within next 20 to 40 years. From the presentation, you will find out why an aging nuclear power plant is a safe, economical, greenhouse-effect acceptable choice and deserves a life extension for the next generation before the alternate energy solution is available.
Topics to be covered:
1. Dresden/Exelonˇs success in revamping the nuclear power plants
How did it happen and what were the main driving forces?
Exelon 2020 roadmap: Exelonˇs concern and approach to the global greenhouse-effect issue
2. Nuclear industry in US from 1980 to 2000
What was happened in nuclear power industry during 80s and 90s?
- Project terminated
- Plant shut down and general public lost confidence in nuclear energy
Nuclear resurgent: In 2011, public support for nuclear energy remains near record levels, with solid majorities believing nuclear energy will and shouldplay a prominent role in the nationˇs energy future.
3. Why nuclear energy
Nuclear power plants are Safe, Economical and Greenhouse-effect acceptable choice to the alternate energy
4. Nuclear safety
INPO /WANO initiatives -- safety culture, training, engagement, communication, leadership
Nuclear industry disasters TMI, Chernobyl, Davis-Besse
5. License renewal of the aging nuclear power plants
What is the basis for license renewal?
What is the roadmap to license renewal?
What can you expect from the license renewal?
What are the major tasks after the license renewal?
What are the concerns from NRC in license renewal?
Trust and faith
