NEI's 2009 Top Industry Practice Awards on Video - Number Three: "The Secret Is Plastic"

By
Over the last two weeks NEI has released two videos out of four highlighting the top industry practice awards that were given out at our annual nuclear conference back in May. Here's our third video installment of the series:
“The Secret Is Plastic,” highlights new applications of plastic piping at two nuclear plants that enhance their operation and decrease the cost of maintaining plant water systems.

Duke Energy employees at the Catawba nuclear station in South Carolina and AmerenUE employees at the Callaway nuclear plant in Missouri shared the Materials and Services Process Top Industry Practice Award for the use of high-density polyethylene piping for plant water systems.

Enjoy!

In the video, they don't really say in what systems this pipe is used. Is it used in safety related systems? One of the displays in the video says something about the service water system. This can be either safety or non-safety related, depending on the nomenclature used at a particular plant.

Here's a few nuggets from our press release of all the TIP awards back in May:

In 1998, Duke Energy employees at Catawba replaced six-inch, low-pressure water piping that provides cooling water to the generator hydrogen coolers. Following the replacement of more than 90 percent of the carbon steel piping with polyethylene piping, flow in the system greatly improved. Catawba is planning to replace 4,000 feet of buried, 10-inch carbon steel piping in the safety-related water system. The use of polyethylene piping will cost $12 million less than the alternative molybdenum piping, and it offers the long-term benefits of being non-corrosive and not requiring cleaning.

In 2008, AmerenUE employees at Callaway successfully used high density polyethylene piping to replace 1,600 feet of underground piping in the safety related essential water system (EWS). The original carbon steel piping required numerous inspections and costly repairs. Callaway completed the replacement of one-half of the buried EWS piping in just eight days in December 2008. It will replace the other half in 2009.

Fluor Invests in NuScale

By
You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap...

Wednesday Update

By
From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin...

Nuclear Utility Moves Up in Credit Ratings, Bank is "Comfortable with Nuclear Strategy"

By
Some positive signs that nuclear utilities can continue to receive positive ratings even while they finance new nuclear plants for the first time in decades: Wells Fargo upgrades SCANA to Outperform from Market Perform Wells analyst says, "YTD, SCG shares have underperformed the Regulated Electrics (total return +2% vs. +9%). Shares trade at 11.3X our 10E EPS, a modest discount to the peer group median of 11.8X. We view the valuation as attractive given a comparatively constructive regulatory environment and potential for above-average long-term EPS growth prospects ... Comfortable with Nuclear Strategy. SCG plans to participate in the development of two regulated nuclear units at a cost of $6.3B, raising legitimate concerns regarding financing and construction. We have carefully considered the risks and are comfortable with SCG’s strategy based on a highly constructive political & regulatory environment, manageable financing needs stretched out over 10 years, strong partners...
