On November 13, 1986, we issued a stay requested by the State of Ohio. The purpose of this opinion, issued after the entry of that order, is to clarify the standards we will apply in reviewing an application for a stay of a proceeding or for a stay directing affirmative action on the party of a federal agency. *290 This stay was requested pursuant to Rule 18 of the Federal Rules of Appellate Procedure, 5 U.S.C. § 705, and 28 U.S.C. § 2349(b). By its motion, Ohio asked the Court to stay the Nuclear Regulatory Agency’s issuance of a full power operating license to the Perry Nuclear Plant, pending review of the Agency’s final order which denied Ohio intervenor status in the licensing proceedings.
As with a stay of a district court order in a civil proceeding pending appeal,
e.g., Commonwealth-Lord Joint Venture v. Donovan,
To justify the granting of a stay, a movant need not always establish a high probability of success on the merits.
Cuomo,
In evaluating the harm which will occur both if the stay is issued and if it is not, we look to three factors: (1) the substantiality of the injury alleged, (2) the likelihood of its occurrence, and (3) the adequacy of the proof provided.
Cuomo,
In order for the reviewing court to adequately balance these factors, the party seeking a stay must address each of the factors regardless of its strength, and provide us with facts and affidavits supporting these assertions. In order to substantiate a claim that irreparable injury is likely to occur, a movant must provide some evidence that the harm has occurred in the past and is likely to occur again.

We would like to point out that this same test does not apply to stays pending review in criminal proceedings pursuant to Rule 38 of the Federal Rules of Criminal Procedure and Rule 9(b) of the Federal Rules of Appellate Procedure. The process involved in criminal cases is entirely different.
Evaluation of the Four Factors
A. Likelihood of Success
In this case Ohio does not seek to permanently enjoin the licensing of the Perry Nuclear Power Plant. Rather, Ohio contends that an adequate offsite emergency evacuation plan has not been developed, and it seeks to participate in a reformulation of the plan by meeting again with members of the Nuclear Regulatory Commission. This plan is required by 10 C.F.R. § 50.47(a)(1) prior to the full power operation of a nuclear power plant.
We believe that Ohio has alleged sufficient facts to demonstrate that a re-evaluation of the plan is warranted. The January 1986 earthquake in Northern Ohio and the April 1986 Chernobyl accident highlighted numerous inadequacies in the evacuation plan. In August 1986, the Governor of Ohio withdrew his approval of the then existing plan, and appointed The Emergency Evacuation Review Team to re-evaluate it. This Ohio cabinet-level task force made preliminary findings which articulated the plan’s deficiencies. Ohio’s memorandum in support of its motion for a stay included this list of deficiencies as well as the affidavit of William Denihan who chaired the task force. The affidavit contained eighteen paragraphs which appropriately detailed the plan’s problems in plain English.
Given the provision of 10 C.F.R. § 2.715(c) which allows an interested state to participate in proceedings before the Commission, and given the apparent inadequacies of the emergency evacuation plans, we believe that Ohio has demonstrated a sufficient probability of success on the merits of its action. We find Ohio’s petition particularly persuasive when considered in conjunction with the severity of the injuries an insufficient emergency plan might cause to the public. The issues of injury and the public interest are addressed below.
B. Irreparable Injury
As we stated earlier, the harm alleged should be evaluated in terms of its substantiality, the likelihood of its occurrence, and the proof provided by the movant.
Cuomo,
Though in this case the likelihood of a nuclear accident is concededly small, the potential severity is enormous. The accident at Chernobyl has demonstrated that the injuries which could result are indisputably irreparable. When compared to the mere economic loss which will result from a delay of full power licensing, it would be unconscionable to allow the full power license to issue absent adequate emergency preparedness plans. It is difficult to visualize particular scenarios, but when dealing with a force as powerful as nuclear energy every effort should be made to minimize risks.
C. Harm to Others
As we stated, mere economic loss does not constitute irreparable injury. Thus, though the licensee is certain to be economically harmed by a delay, the loss is not substantial. This economic loss can later be recouped when the plant begins full power operation. The licensee has submitted no proof of any additional non-economic harm which may result from the delay of the issuance of a full power operating license. Nuclear power as an energy source involves certain risks, both economic and physical, and a utility which chooses to construct a plant necessarily assumes the risk of delay and the accompanying economic loss. The economic harm is far less severe than the potential danger posed to the public if an accident occurs without adequate evacuation plans in force. Unlike the situation in
Cuomo
where the utility
*292
alleged that a delay in the granting of a five percent power license might result in the loss of valuable personnel which would cause irreparable injury, we find that the delay in granting of this license would not present such a risk. Even if it did, we agree with the District of Columbia Circuit that these risks and costs are self-imposed.
Cuomo,
D. The Public Interest
Though there is more than one public interest involved here, the most crucial concern is public safety.
Cuomo,
Conclusion
It is our belief that the petitioner adequately demonstrated the need for a stay in this situation. For these reasons the motion was granted.
ORDER
We have considered all of the documents filed by the parties in this proceeding in light of the criteria set forth in
Cuomo v. United States Nuclear Regulatory Commission,
Because here we are considering the issuance of a full power license and not a five percent power license as in Cuomo, we find the safety considerations to be significant, whereas the economic considerations regarding the potential loss of personnel are less likely to be a problem, therefore,
It is ORDERED that implementation of the full-power operating license for the Perry Nuclear Power Plant allowing it to exceed its current five percent power level be and hereby is stayed. The Clerk is directed to set an expedited briefing schedule for this case. All interested parties will be permitted leave to intervene upon seeking leave from this Court.
