) -- Stocks settled lower on Monday as investors worried about the impact of the devastating earthquake and tsunami in Japan Friday, and as the nuclear crisis in the country deepens.

led the Dow lower, shedding 2.2% to $19.92 at the closing bell. GE supplied one of the reactors at

Tokyo Electric's


Fukushima nuclear plant, which has been rocked by two explosions in the last three days.

The latest explosion Monday is at the plant's No. 3 reactor, which authorities have been trying to cool after a system failure in the wake of the earthquake.

Hundreds of people in the vicinity of the plant have been ordered to stay indoors, although the plant operator has said the radiation levels were still within legal limits.

The disaster has raised concerns about the

U.S.'s own nuclear and energy policy, with uranium stocks coming under pressure.

plunged more than 22% in the wake of the nuclear crisis in Japan.

"The nuclear power industry will come under scrutiny, and accordingly, nuclear-oriented stocks will fall," Luminous Capital partner Alan Zafran said in a note. "A number of governments may delay or even reconsider plans to expand their atomic energy strategies. Conversely, natural-gas stocks and other companies whose fortunes are tied to alternative energy techniques may rise as investors anticipate a correlating shift in consumption for their services."

The damaged Unit 1, left, and Unit 2, right, of the Fukushima Dai-ichi nuclear plant are seen in Okumamachi, Fukushima Prefecture.

Japan's Nikkei tumbled 6.2% on Monday, the first full trading day following the quake.

Bank of Japan voted Monday to double the size of its asset purchase program to a record 15 trillion yen ($183.7 billion) to ease liquidity concerns as Japan's heavily debt-burdened economy deals with the impact of what government officials have called its biggest crisis since World War II. The U.S. dollar/yen was volatile Monday with the dollar down 0.2% at 81.691 yen.

Estimates of the death toll from the disaster continue to climb, with the official estimate at 1,897, according to


. Tens of thousands are feared dead, according to

The Associated Press,

with rescue workers still unable to reach some of the hardest-hit areas of northeast Japan.

Ian Shepherdson of High Frequency Economics noted that the damage done to Japanese ports could make trade disturbances more likely but expects the overall impact from the disaster on the United States to be small.

"The importance of trade with Japan has been trending down for many years as a result of Japan's depression," the economist wrote in his daily note.

"The Japanese economy will be even weaker after the quake than before, though U.S. companies exporting capital equipment might enjoy a boost from reconstruction work. We simply don't know for how long the flow of goods to

the U.S. from Japan will be disrupted, but there will be some impact on the flow of goods and parts," wrote Shepherdson.

Asian markets finished mixed. Hong Kong's Hang Seng gained 0.4% and India's Sensex rose 1.5%. In Europe, Germany's DAX lost 1.7%, while the U.K's FTSE fell 0.9%.

The April crude oil contract was flat at $101.21 a barrel. Crude oil prices fell Friday on fears that demand from Japan, the third largest consumer of oil, will drop.

Meanwhile, tensions in the Middle East appear to have temporarily taken a back seat in investors' minds in the wake of Japan's crisis. Rebel forces in Libya fled the coastal oil town of Brega as President Moammar Ghadafi's supporters gained ground. Ghadafi's forces have been bombing the insurgents' base in Benghazi as well.

Fears that protests could spread to Saudi Arabia, however, appear to have abated somewhat after Friday's "day of rage" protest passed by relatively peacefully.

There were no economic reports scheduled for release Monday.
