Running a Nuclear Plant on a Commodore 64?

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.

How Nanomaterials Can Make Nuclear Reactors Safer and More Efficient

The following is a guest post from Matt Wald, senior communications advisor at NEI. Follow Matt on Twitter at @MattLWald.

From the batteries in our cell phones to the clothes on our backs, "nanomaterials" that are designed molecule by molecule are working their way into our economy and our lives. Now there’s some promising work on new materials for nuclear reactors.

Reactors are a tough environment. The sub atomic particles that sustain the chain reaction, neutrons, are great for splitting additional uranium atoms, but not all of them hit a uranium atom; some of them end up in various metal components of the reactor. The metal is usually a crystalline structure, meaning it is as orderly as a ladder or a sheet of graph paper, but the neutrons rearrange the atoms, leaving some infinitesimal voids in the structure and some areas of extra density. The components literally grow, getting longer and thicker. The phenomenon is well understood and designers compensate for it with a …

Missing the Point about Pennsylvania’s Nuclear Plants

A group that includes oil and gas companies in Pennsylvania released a study on Monday that argues that twenty years ago, planners underestimated the value of nuclear plants in the electricity market. According to the group, that means the state should now let the plants close.


The question confronting the state now isn’t what the companies that owned the reactors at the time of de-regulation got or didn’t get. It’s not a question of whether they were profitable in the '80s, '90s and '00s. It’s about now. Business works by looking at the present and making projections about the future.

Is losing the nuclear plants what’s best for the state going forward?

Pennsylvania needs clean air. It needs jobs. And it needs protection against over-reliance on a single fuel source.

What the reactors need is recognition of all the value they provide. The electricity market is depressed, and if electricity is treated as a simple commodity, with no regard for its benefit to clean air o…

Why Nuclear Plant Closures Are a Crisis for Small Town USA

Nuclear plants occupy an unusual spot in the towns where they operate: integral but so much in the background that they may seem almost invisible. But when they close, it can be like the earth shifting underfoot., the Gannett newspaper that covers the Lower Hudson Valley in New York, took a look around at the experience of towns where reactors have closed, because the Indian Point reactors in Buchanan are scheduled to be shut down under an agreement with Gov. Mario Cuomo.

From sea to shining sea, it was dismal. It wasn’t just the plant employees who were hurt. The losses of hundreds of jobs, tens of millions of dollars in payrolls and millions in property taxes depressed whole towns and surrounding areas. For example:

Vernon, Vermont, home to Vermont Yankee for more than 40 years, had to cut its municipal budget in half. The town closed its police department and let the county take over; the youth sports teams lost their volunteer coaches, and Vernon Elementary School lost th…
