> New Reactor Could Make Nuclear Power As Economical As Gas in U.S.

>

> Jun. 25--AECL Technologies yesterday announced its plans to introduce a

new

> nuclear reactor into the U.S. market that company representatives say is

> economical enough to rival natural gas as a source of power.

>

> The Ontario, Canada-based company is in the process of licensing its

ACR-700

> reactor --which AECL says is cheaper and faster than most U.S. reactors --

> in the United States and abroad.

>

> "Our confidence in this product and this technology we're bringing to the

> market is very high," said Robert Van Adel, chief executive officer of

> Atomic Energy of Canada Ltd., the parent of AECL Technologies.

>

> The company is in negotiations with several U.S. companies interested in

> breaking into the nuclear energy market. However, little can be done until

> the Nuclear Regulatory Commission approves the reactor's design for use in

> the United States.

>

> AECL has already started going through the licensing process with the NRC,

> Mr. Van Adel said.

>

> AECL's plans come at a time of heightened concern about the safety of

> nuclear reactors, and some question whether the company's reactor is

really

> more economical than what is already in place in the United States.

>

> Mr. Van Adel said this reactor is both more economical and safer than

other

> reactors. It uses a more cost-efficient cooling system and is a

700-megawatt

> construction, rather than the 1,000-megawatt reactors that are now common

in

> the United States, he said.

>

> The ACR-700 could be built for $1,000 per kilowatt and will operate for

$30

> per megawatt-hour, which is comparable to gas-fired technologies, he said.

>

> AECL predicts its ACR-700 technology will be competitive in price with

> natural gas by 2010.

>

> "We believe that the ACR-700 is the first reactor on the market that has

the

> right combination of cost, safety, security, size, reliability and

> environmental advantages to meet the needs of generators selling into

> competitive markets," Mr. Van Adel said.

>

> David Lochbaum, an expert in nuclear safety for the Union of Concerned

> Scientists, said the company could face problems selling new reactors,

> because at least 85 percent of the existing reactors in the United States

> are expected to be relicensed.

>

> "As those reactors get relicensed, that delays the period of time they

have

> to be replaced," he said.

>

> Since September 11, many have questioned the vulnerability of nuclear

power

> plants to attack and the wisdom of building more reactors. There are 103

> licensed nuclear plants in 31 states, according to the Nuclear Energy

> Institute.

>

> Nuclear energy, which generates about 20 percent of the country's

> electricity, is considered to be a cleaner alternative to power generated

by

> natural gas, oil and coal. However, there have always been concerns about

> how to store the 2,000 metric tons of spent radioactive fuel produced each

> year in the United States.

>

> This high-level radioactive waste can be very dangerous, but according to

a

> survey by the Nuclear Energy Institute, about 66 percent of Americans

> believe nuclear power is a safe option.

>

> Despite the increasing public acceptance, there are no known plans to

build

> more nuclear power plants in the United States, and this could pose

problems

> for AECL in marketing its new reactor, Mr. Lochbaum said.

>

> It also costs more to get a nuclear plant up and running, and it is

unlikely

> that nuclear power's share in U.S. power generation will grow, he said.

>

> Mr. Lochbaum also questioned the company's use of a water-based cooling

> system, which he says is being dismissed in most of the world in favor of

> more economical gas cooling models under development.

>

> "It doesn't look like anyone in the U.S. has been able to find a way of

> using water economically," Mr. Lochbaum said.

>

> But AECL is confident of its chances in the United States. He said the

> company is working with several major U.S. utilities to bring this reactor

> to the country.

>

> There are 31 of AECL's CANDU reactors in place worldwide and six more

under

> construction. AECL is owned by the Canadian government.

ACR

review.

> Licensing steps also are under way in Canada and the U.K., said Van Adel.

> original CANDU heavy-water reactor upon which it is based, said Van Adel.

>

> For best cost efficiency, AECL plans to pair the 700-megawatt capacity

> reactors in its plant design. The ACR-700 still employs a heavy

> water-moderated reactor core, like the traditional CANDU reactor.

>

> But it replaces the heavy-water cooling system with a light-water cooling

> system, shaving "several hundred million" off the cost of building a

> twin-unit generating plant, or about $120 million per unit, Van Adel said.

>

> Other cost-savings are derived from the off-the-shelf design, which allows

> for the compact units to be built at a central factory and shipped to

> generation sites, rather than designed and built at the plant site, he

said.

>

>

> The result is a plant that is cost-competitive with state-of-the-art

natural

> gas-fired generating units, Van Adel said. The plant's total capital costs

> are $1,000 per kilowatt, excluding interest. The levelized cost is $30 per

> megawatt-hour, which compares favorably to gas.

>

> The AECL-700 is "the first of a new generation of reactors to meet the

cost

GF

> Energy LLC. AECL is a client of Gale's firm.

>

> "The new build of nuclear will not happen unless the economics are

> attractive," said Van Adel.

>

> The design is also compact, Van Adel said, allowing for a far smaller

> "footprint" at the plant site, a desirable attribute since most if not all

> new U.S. nuclear development is expected to occur at existing nuclear

power

> plant sites.

>

> Other benefits include the ability to refuel without shutting down the

> plant. The uranium fuel is also cheaper than that typically used in

existing

> light-water reactors in the U.S. While the old-generation CANDU used

natural

> uranium fuel, the ACR-700 design calls for a fuel that is enriched 2%.

U.S.

> reactors typically use a fuel enriched to 3.5%, said David Torgerson, vice

>

> The plant also is more readily refurbished to allow an extension of the

> plant's operating life, Torgerson said.

>

> AECL is promising to build an operational plant within four years of

> licensing, and is offering to mitigate the investment risk by providing

> various guarantees.

>

> Van Adel said the plant's design is being changed in the wake of the Sept.

> 11 terrorist attacks, but he declined to elaborate on the improvements to

> AECL's design calls for a nuclear reactor powered by smaller, individual

> pressure tubes that contain fissionable uranium, which drives the reactor.

>

> Exelon in April dropped out of an international consortium developing a

> At a cost of about $1,000 per kilowatt of generation, the 700 megawatt

AECL

> That is about double the cost of a combined-cycle natural gas turbine

plant.

> Dominion will seek a permit for its North Anna site in Virginia, Entergy

for

>

> The utilities will submit applications by the autumn of 2003 with the aim

of

>

> The Energy Department said it will pay for up to 50 percent of the cost of

> each early site permit, spending about $17 million in total to help the

> three companies.

>

> Energy Secretary Spencer Abraham said the projects are the "first major

> elements" of the administration's plan to help industry build at least one

> new nuclear power plant by 2010.
