Vitter Leads Senators, Caution NRC on Hasty Rule Implementation
February 4, 2013
Senator David Vitter (R-La.), top Republican on the Environment and Public Works Committee, along with six other Senators urged Chairman Allison Macfarlane of the Nuclear Regulatory Commission (NRC) to carefully approach regulatory changes before implementing costly requirements.
"It is hugely important for nuclear power plants in the United States to proceed with high safety standards, but the NRC must move forward having considered all consequences, including the cost-benefit analysis," said Vitter. "It's not the time to be rash with hasty new rules, especially when the NRC has added forty-plus ‘safety enhancements' to the Tier 1 requirements that have not been carefully reviewed."
The NRC has been re-evaluating the United States' approach to safety measures for nuclear power plants since the March 2011 earthquake and tsunami that led to the accident at the Fukushima Daiichi nuclear plant in Japan. The Senators note in the letter that the official report of the Fukushima Nuclear Accident states that the accident may have been preventable had Japan implemented certain safety standards already in place in the United States.
The Senators signing the letter are: David Vitter (R-La.), Jeff Sessions (R-Ala.), John Barrasso (R-Wyo.), John Boozman (R-Ark.), Mike Crapo (R-Idaho), James Inhofe (R-Okla.), Roger Wicker (R-Miss.).
Text of the letter is below.

The Honorable Allison M. Macfarlane
U.S. Nuclear Regulatory Commission
11555 Rockville Pike
Rockville, MD 20852
Dear Chairman Macfarlane:
We write to inquire about the Nuclear Regulatory Commission's (NRC) ongoing regulatory analyses arising from the Fukushima accident. Since the March 11, 2011 earthquake and tsunami that led to the accident at three nuclear reactors at the Fukushima Daiichi plant in Japan, the NRC has focused significant resources on understanding and responding to that accident. The NRC has a duty to assure the safe operation of nuclear power plants in the United States. As you continue this important work, we believe the NRC should strive to take a prudent and thoughtful approach to evaluating the lessons of Fukushima and, where necessary after a review and cost-benefit analysis, incorporate improvements to its regulations and policies to take into account the lessons learned from Fukushima.
However, we are concerned that the NRC appears to be moving forward with implementation of costly post-Fukushima recommendations beyond those identified as Tier 1 without fully analyzing the differences between the regulatory atmospheres of Japan and the United States. The Official Report of the Fukushima Nuclear Accident by the National Diet of Japan noted substantial differences between the Japanese and U.S. nuclear safety culture and regulation, even noting that the accident may have been preventable had Japan also implemented certain regulations adopted by the NRC post-9/11. Despite this, the NRC has continued to pursue post-Fukushima changes without a complete analysis of the differences between Japan and the U.S. This raises concerns whether the NRC is appropriately addressing potential safety issues that actually exist at U.S. plants and whether the public may erroneously presume that the U.S. shares the same vulnerabilities as Japan.
The list of "safety enhancements" under consideration by the NRC has grown to approximately forty, even though the NRC has already achieved safety benefits from the implementation of Tier 1 requirements. The NRC should take the time to determine what safety benefits have already been realized and consider further changes in light of those benefits. The NRC should also continue its traditional practice when employing a cost benefit analysis. The need for this discipline is necessary as the NRC continues its discussions related to filtering strategy for certain boiling water reactors. As with other industries, the current economic climate poses challenges to nuclear power, and the NRC should fully understand the true impact that any new requirements will have. More importantly, potential safety benefits should be determined using a risk-informed, performance-based approach. Without completing this analysis, the risk of unintended consequences from regulatory changes may be increased without any certainty that the intended safety benefits will occur.
In an important and valuable letter dated January 15, 2013, Chairman Fred Upton of the House Committee on Energy and Commerce and twenty of his colleagues wrote to express similar concerns and request additional information on the NRC's ongoing post-Fukushima review. We believe Chairman Upton's letter merits full consideration by the NRC along with a thorough response to his request for information.
We would also ask for a letter from you that:
(1) Confirms that the NRC is completing a thorough analysis of the differences between the regulatory atmosphere in Japan and the U.S., and an explanation of the methodology of how that analysis is being conducted;
(2) Describes whether and how the NRC has given due consideration for safety benefits gained by post-Fukushima actions already taken; and
(3) Identifies any areas where the NRC has departed from a thorough and systematic cost-benefit analysis in imposing additional requirements at the nation's nuclear plants since the Fukushima accident.
We respectfully urge the NRC to take its time to make the correct regulatory changes that follow a responsible and thorough approach to ensure plant safety and that any new requirements established for the U.S. commercial nuclear reactor fleet are justified by the law, supported by sound data, and warranted by a robust cost-benefit analysis.
