Americans by a 2-1 margin oppose building more nuclear power plants in the United States, an 11-point spike in opposition from a few years ago.

In the aftermath of Japan's nuclear plant crisis, 64 percent in this ABC News/Washington Post poll oppose new nuclear plant construction, while 33 percent support it. "Strong" opposition now far outstrips strong support, 47-20 percent. Opposition is up from 53 percent in a 2008 poll, and strong opposition is up even more, by 24 points.

Charts and Questionnaire

The results reflect the significant challenges facing the nuclear power industry, which had been reaching for greater acceptance on the basis of factors including high oil prices, environmental concerns prompted by the Gulf oil spill a year ago and efforts to curb greenhouse gas emissions.

Opposition is not merely a not-in-my-back-yard phenomenon. The survey, conducted for ABC News by Langer Research Associates, finds that 67 percent of Americans oppose construction of a nuclear plant within 50 miles of their home -- not significantly different than the number who oppose it regardless of location.

Resistance is bipartisan, with majorities of Democrats, Republicans and independents alike opposed to new nuclear plant construction. Still, there are differences among groups; opposition is higher among Democrats (75 percent, vs. 59 percent of Republicans and independents combined), women (73 percent, vs. 53 percent of men) and liberals (74 percent, vs. 60 percent of moderates and conservatives).

Support for building more nuclear plants has fluctuated in the past, showing sensitivity to nuclear crises. Starting at 61 percent in the mid-1970s, support fell sharply after the Three Mile Island accident in 1979 and bottomed out at just 19 percent in May 1986 after the Chernobyl crisis (which began 25 years ago next week).

SAFE? -- Most Americans do not flatly say that nuclear power is unsafe; indeed, 53 percent say it's safe overall, 11 points above the immediate post-Chernobyl level. But just 23 percent see it as "very safe," which apparently is what's needed to sustain public support.

Perceptions of safety dramatically affect support for new nuclear plants. Among people who think nuclear power plants are very safe, 84 percent favor building new ones. But that falls to 33 percent of those who just think it's only somewhat safe. And those who think it's unsafe are nearly unanimous (93 percent) in their opposition.

In another measure, 42 percent say the crisis in Japan has made them less confident in the safety of nuclear power overall; 51 percent say it's had no effect. This, too, ties in closely with support for construction: Among those who are less confident now, 84 percent oppose building new plants. Among those whose opinions haven't changed, opposition falls to 48 percent.

Methodology

This ABC News-Washington Post poll was conducted by telephone April 14-17, 2011, among a random national sample of 1,001 adults, including landline and cell-phone-only respondents. Results have a margin of sampling error of 3.5 points.

The survey was produced for ABC News by Langer Research Associates of New York, N.Y, with sampling, data collection and tabulation by TNS of Horsham, Pa.
