The Precautionary Principle was invented to prevent the large-scale deployment of civilian nuclear power.

True: historical scholarship shows the precautionary principle was first formulated mainly to stop the large-scale deployment of civilian nuclear power. Mostly true: opposition to nuclear power was a primary driver of its earliest formulation, alongside closely related concerns. Mostly false: the principle arose mainly in other environmental contexts, such as German air-pollution and forest law or marine pollution, and was applied to nuclear power only later or secondarily, so a real link is overstated as its purpose. False: scholarship shows no meaningful link between the principle's origin and nuclear power.

Set before the research began.

1. E1 Introduction European Environment Agency · 2001

   “the precautionary principle and its application to environmental hazards and their uncertainties only began to emerge as an explicit and coherent concept within environmental science in the 1970s, when German scientists and policy-makers were trying to deal with ‘forest death’ (Waldsterben) and its possible causes, including air pollution.”

2. E2 Introduction European Environment Agency · 2001

   “The Vorsorgeprinzip (‘foresight’ or ‘precautionary’ principle), in the German Clean Air Act of 1974, as elaborated in the 1985 report on the Clean Air Act (Boehmer-Christiansen, 1994) also included elements such as:”

   “In 1972, West Germany amended its constitution to address the sulfur dioxide and nitrogen oxide pollution that caused acid rain, which was, in turn, causing widespread damage to German forests.”

4. E4 Introduction European Environment Agency · 2001

   “‘The participants... will continue to apply the precautionary principle, that is to take action to avoid potentially damaging impacts of substances that are persistent, toxic, and liable to bioaccumulate even where there is no scientific evidence to prove a causal link between emissions and effects.’”

The European Environment Agency's report traces the precautionary principle as an explicit concept to 1970s Germany, where it was developed to deal with forest death and air pollution (E1). The report places it in the Vorsorgeprinzip of the German Clean Air Act of 1974 (E2). An independent history also ties German action in 1972 to acid-rain damage to forests (E3), and E4 shows the principle applied to persistent toxic substances. None of these sources names nuclear power as the reason the principle was created, which fits the "mostly false" criterion: it arose mainly in other environmental contexts. The evidence does not mention nuclear power at all. That is not enough to show there was no link whatsoever, so "false" is not supported.
