Dear Congressman Walker:

This is in reply to your letter of April 24 and July 25,1979 to Mr. Carlton Kammerer regarding questions which you circled on a letter to you from Mrs. Gudrun Schlief. The answers to those questions are enclosed. I am sorry that this reply has been delayed. As you know, the NRC has been occupied with continued support. of the efforts at Three Mile Island, orders to other facilities, appearances before the President's Commission and various committees of Congress that are investigating the Three Mile Island accident, and the realignment of our own resources and priorities to give immediate attention to the problems resulting from the accident. Sincerely, ret-=0 T. A. Rehm 1 / Lee V. Gossick Executive Director for Operations

QUESTIONS & RESPONSES TO CONSTITUENT [f! Question 1 How much radiation did we receive on March 28 and 29,1979 and thereaft.er from TMI within the 5 mile,10 mile and 20 mile radiuses as a) inhalation e.ose (which I found mentioned nowhere) and b) a secondary dose from water, feeds and skin contact with contaminants? And which radioactive elements were found? Answer Enclosed is a copy of report NUREG-0558 on " Population Dose and Health Impact of the Accident at the Three Mile Island Nuclear Station," giving preliminary estimates for the period of March 28 through April 7, 1979. Skin doses are discussed on pages 66-70, inhalation doses on pages 70-74, and thyroid dose from ingestion of milk on pages 74-77. On page 4, the principal radionuclides are given as radioactive xenons and some iodine-131. Question 4 How is the public protected from the long-term, low-level radiation of all existing nuclear power plants, fuel-recycling plants, waste disposal sites, military storage sites of nuclear weapons and during transportation of any nuclear material on our roads and highways throughout the U.S.? Answer Enclosed are two parts of NRC Rules and Regulations relating to this question. Part 20 on " Standards for Protection Against Radiation" concerns protection against radiation hazards arising out of activities licensed by the NRC. . Part 71 on " Packaging of Radioactive Material for Transport and Transportation of Radioactive Material under Certain Conditions" applies to a licensee who delivers licensed materials to a carrier for transport or who transports such material outside the confines of his plant or other place of use. Question 6 The radon issue: As you know, the uranium mill tailings emits the deadly radon gas, which has a half-life of 4 billion years. These mill tailings are piled up every-where at mining sites in the U.S. How can U. S. Congress protect the people and all life forms on earth, on which we depend, from this raden gas? Answer Radon-222 has a half-life of 3.8 days. It is a daughter of radium-226, which has a half-life of 1600 years and which has an occurrence in natural uranium of about one part in three million. O n c e.., LA ..m

. Information on radon is contained in the enclosed pages 4-34 through 4-36 of NUREG-0534, which is the Draft Environmental Statement related to operation of The the Virgil C. Summer Nuclear Station, Unit No.1, published in June 1979. conclusion of NRC staff is that the health effects on the U. S. population from the uranium fuel cycle of a large power reactor, including the effects of radon, are insignificant when compared to the potential health effects resulting from all natural background sources. Question 7 The aircraft issue: Is there a 100% insurance, that the reactor building of every nuclear power plant in the U.S. can withstand an accidental airplane crash of a 747 or C-5-A? Answer Enclosed is NRC Standard Review Plan, Section 3.5.1.6 on " Aircraft Hazards." This states that the plant is considered adequately designed against aircraft hazards if the probability of aircraft accidents resulting in radiological consequences greater than the exposure guidelines given in Part 100 of NRC Rules and Regulations is less than about one C. ten million per year. Other-wise, aircraft accidents should be considered in the design of the plant. In most cases, the above acceptance criterion is met. One case where the plant was specifically designed against aircraft hazards is Three Mila Island Unit 1. This is discussed in the enclosed excerpt from the " Safety Evaluation" of July 11, 1973, which states that impact hardening of the Class I structures was achieved by reinforcement of outer walls, thickening of concrete sections, and unique internal features. In addition, special fire protection and ventilation features were provided to cope with aircraft crashes. Similar features were incorporated in Three Mile Island Unit 2. Question 8 Do we have the legal and moral right to operate nuclear power plants and to add to the existing nuclear waste in any way until we have solved the nuclear waste disposal problem 100%? How many containers have been found leaking after only a short period of time, short compared with the half-life of the radioactive waste? Answer In denying a rulemaking petition by the Natural Resources Defense Council on June 27,1977, the Nuclear Regulatory Commission stated in part (Federal Register, Vol. 42, page 34391): "Because the petition seeks a finding that safe waste disposal car be accamplished immediately, the Canmission has determined that the rule-making petition should be denied. The Commission notes that prior to n a c. c.,, L 4. . _.,w

/ 'l @ l,)?;} any licensing of high-level waste disposal facilities, a detailed finding concerning the safety of the proposed facilities will be made. There is., we believe, a clear distinction between permanent disposal of wastes ar.d their interim storage. The Commission must be assured that wastes generated by licensed power reactors can be safely handled and stored as they are generated. As part of the licensing process for an individual power reactor facility, the Commission does review the facility in question in order to assure that the design provides for safe methods for interim storage of spent nuclear fuel. But it is neither necessary nor reasonable for the Commission to insist on proof that a means of permanent waste disposal is on han/ at the time reactor operation begins, so long as the Commission can. be reasonably confident that permanent dis-posal (as distinguished from continued storage under surveillance) can be accomplished safely when it is likely to become necessary. Reasonable progress towards the development of permanent disposal facilities is presently being accomplished. Under these cir-cumstances a halt in licensing of nuclear power plants is not required to protect public health and safety." This was upheld by the United States Court 01 Appeals, Seccnd Circuit, in NRDC v. NRC, 582 F.2d 166 (2d Cir.1978). However, in a recent decision by the Court of Appeals for the District of Columbia Circuit in Minnesota

v. NRC, Nos. 78-1269, 78-2032 (D.C. Cir., May 23,1979), that Court directed the Commission to make a determination with regard to the above finding, as to whether safe and adequate nuclear waste storage methods would be available by a certain date. The Commission is currently considering this requirement.

With regard to leaking containers of radioactive waste, the following is an excerpt from page 75 of the " Report to the President by the Interagency Review Group on Nuclear Waste Management" of March 1979: s " Currently, HLW [high level wastes] frcxn the defense programs is stored in underground tanks (Hanford, Washington, and Savannah River, South Carolina) and bins (Idaho Falls, Idaho) in the form of various liquids, salts, sludges, dry c:1 cine powder (Idaho Falls only), and separated heat producers (Hanford only). "The Savannah River and Hanford high level wastes were initially stored in single shell tanks or tanks with a ' saucer' as secondary containment (Savannah River only). Corrosion e stress points caused leaks that gained natic:d attention. Suosequently, an aggressive interim star.ge strategy was adopted. Improved storage methods are being de*; eloped and double shelled tanks are being constructed to stc;e liquids at Hanford and all forms of HLW waste at Savannah River. TRU [ transuranic] waste is stored in containers on storage pads. All stored HLW and TRU waste is monitored carefully to ensure it remains immobile." c :,~c.,, L A.

llgRIGQ ~ - u Question 9 What has U. S. Congress done to find the unaccounted for, highly radioactive material, which has disappeared from U. S. stockpiles? Answer Most of the special nuclear material that is unaccounted for is uranium enriched in U-235, which is not highly radioactive. The rest is plutonium and uranium-233, which are much more radioactive. Unaccounted-for material usually involves processing operations not stockpiles and shows up as inventory differences, which do not necessarily mean that the material has disappeared. Such differences may be caused by a variety of factors including clerical error, material trapped in process lines or equipment, and inaccurate measurement of scrap and other hard-to-measure items. It may be impossible to state with certainty the exact cause of a specific inventory difference. Over the years, committees of Congress have held a number of hearings on special nuclear material that is unaccounted for. Congress explicitly provided in the Energy Reorganization Act of 1974 for an Office of Nuclear Material Safety and Safeguards within the NRC, mandated to review existing safeguards for nuclear facilities and materials and, in particular, to carry out (1) monitoring, testing and recomendations for upgrading material acctunting systems; (2) development of contingency plans to deal with threats, thefts and sabotage of materials or facilities; and (3) a study of the need for, and feasibility of, establishing a Federal security agency to administer safeguards. Enclosed is a excerpt from the 1976 Annual Report of NRC with regard to meeting these Congressional mandates. In August 1977, the NRC issued a report (NUREG-350) which showed, on a year-to-year basis, a downward trend in inventory differences, particularly for highly enriched uranium, in spite of the increasing amounts of material handled by the licensed facilities. The downward trer.d can be attributed to improved measurement techniques and a strengthening of NRC safeguads regulations. Question 10 I ask you to have all U. S. Government and privately gathered data (from 1948 until now and into the future) on protection against radioactivity (foods, medicine, herbs, clothing, exercises, etc.) made immediately available to the citizens of Pennsylvania and the U.S. They deserve it after they lived through the TMI nightmare. Answer The responsibility of informing the general public about protection against radio-active contamination rests with the States and the Department of Health, Education and Welfare, the Environmental Protection Agency, and the Department of Energy of the Federal Government.

REVIEW RESPONSIBILITIES, Primary - Accident Analysis Branch (AAD) Secondary - Structural Engineering Branch (SEB) Auxiliary and Power Conversion Systems Branch (APC38) I. AREAS OF REVIEW The staff reviews tha applicant's assessment of aircraft hazards to the plant. The purpose of the revies is to assure that either aircraft hazards are eliminated as a design basis concern or appropriate design basis aircraft have been chosen and properly characterized as The revicw also involves a determination of adequate protection to impact and fire hazards. against firc hazards for design basis events. Some information relating to this review is contained in Section 2.2 of the applicant's safety analysis report (SAR). e.g.. facility locations, projected traffic, and accident statistics. The APCSB Jetermines which structures and components are to be protected, and the SEB assures that adequate protection has been provided. II. ACCEPTANCE. CRITERIA The plant is considered adequately designed against aircraft hazards if the probability 1. of aircraf t accidents resulting in radiological consequences greater than 10 CFR Part 100 exposure guidelines is less than about 10'I per year $ee Standard Review Plan 2.2.3). The probability is generally considered acceptable by inspection if the level of air-2. craft activity near the site falls below the criteria given in Section 2.2.3 of Reg-ulatory Guide 1.70 (Ref. 2) for analysis of hazards due to comercial, experimental, and general aviation aircraft. For military airsbace, a minimum distance of five miles from the reactor is adequate for low level training routes except those associated with usage greater than 1000 flights per year or activities (such as practice bombing) where an unusual stress situation exists. Aircraft accidents which could lead to radiological consequences in excess of the 3. exposure guidelines of 10 CFR Part 100 with a probability of occurrence greater than about 10~7 per year should be considered in the design of the plant.
