Running a Nuclear Plant on a Commodore 64?

By

complete Well, all right, not really – but welcome retro-computing fans, anyway – but we have been interested in how the nuclear energy utilizes computer systems. We know the basics of security – don’t point crucial systems at the internet is a big one – but on a day-to-day basis, how does the industry interact with computers? What does it do with them that’s unique?

Here’s part of the answer:

The new agreement, which adds to the original contract signed in April 2008, covers additional work necessary for Accenture to support business processes, including configuration management of detailed design data and management of data associated with required inspections; testing, and analyses; and use of acceptance criteria involved with the construction of nuclear energy facilities.

The agreement is between UniStar and Accenture, and it gets a little complicated after that. UniStar is jointly owned by Constellation and EDF, tasked with developing, as its home page says, “the safest, most reliable and most economical construction and operational fleet of new nuclear facilities;” Accenture is a consulting company (they produced a poll about nuclear energy that we spotlighted awhile ago). The computer platform described above is called Galaxy. It sounds, to put it mildly, multifaceted.

Daniel P. Krueger, managing director of Accenture’s Power Generation practice said, “We believe Galaxy’s standardized and interoperable approach delivers the most effective capabilities to support the licensing, design, construction and operation of new nuclear energy facilities. Our work with UniStar continues to position Accenture at the leading edge of the new nuclear energy renaissance.”

Some buzz words in there. Standardized how? Interoperable with what? (Our guess: written in Java, run as a web-based service, hosted on Unix/Linux – that would capture those elements pretty well.)

So, it sounds like a business logic platform – or suite of programs – to help the multitude of vendors and in-house folks stay in sync while they track all the elements that go into building new plants. And since this is a Constellation/EDF deal, Maryland’s Calvert Cliffs looks like the perfect place to run the system through its paces.

We wonder, though – will Accenture promote this system to other entities? Seems like it should, being standard and interoperable and all.

The Commodore 64, Introduced in 1982, remains the best selling computer model ever. Why? It was cheap (as low as $99) and it stayed on the market for some 12 years while Commodore tried fruitlessly to move customers to more advanced (C 128, Plus 4) platforms. It took the company going out of business to kill it. Remarkable, even if we doubt it saw much use at a nuclear power plant.

For what its worth, the Commodore 64 is more powerful then the computers running most nuclear power plants.

FWIW, computers don't "run" nuclear plants, unless you are talking about the Organic Computer Mark I, and maybe you are. The Organic Mark I doesn't have the number-crunching brute force of a C-64, but it has a subtle, intuitive brand of intelligence that has yet to be matched in the silicon world.

The automatic safety features are "run" by computers (or in some cases discrete logic cards).

Not really a "computer" in the traditional sense of a PDP. It doesn't run safety system "software". I worked on the DSS developed in the UK back in the early 1980s. They were very careful to assure that everything was really "hard wired", i.e., etched into a chip. The questions the regulators kept bringing up about software V&V were just insumountable.

Well, the system you are use to may not run software, but some of them do. Westinghouse's "Eagle 21" system uses an Intel 286 chip and runs x86 software that your modern computers are still backwards compliant with (IE: that code should run even on the most advanced x86 chips).

There is a whole range of systems between analog, discrete digital systems, and software based digital systems. Many plants use a combination of systems. But you are right, the non-safety systems are usually much more advanced than the safety systems because its hard to PROVE something as complicated as a modern CPU (with a billion transistors) will not fail. People should remember that while your computer may be expected to last 5 years a nuclear reactor is designed to last 60 years (although the logic cards are periodically replaced).

Computer replacement is often driven by the need for more processor power to operate more complex and demanding software, which tends to bloat somewhat rapidly. I know when I have replaced a computer the old was was working fine, it just would not run (very well) some cool new program I wanted to have.

I had a PDP-11 at work that ran fine from 1975 until 1988 when the software updates migrated to 386-based systems. I don't know if there are similar drivers in the control systems business.

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...
