In this article, we analyze the intractability of the low-level radioactive waste debate in California through the construction and examination of policy frames and their associated policy narratives. Relying primarily on reports, formal comments, and written correspondence, we reconstruct three policy frames and explore their interaction in the public debate through the policy stories told by the actors. We analyze how policy actors using these policy frames appropriate available information, value scientific input, and respond to uncertainty in technical and regulatory (...) information to create policy stories. These policy frames and their associated policy narratives demonstrate how policy actors differ in their drivers for action, bases for trusting claims, and response to uncertainty. These differences lead to divergent characterizations of the risk of low-level radio-active waste disposal. This analysis provides insight into the dynamics of intractable policy controversies.
