JOINT COMMUNIQUE BY WORLD LEADERS PARTICIPATING IN THE TOKYO SUMMIT Following ic the text of the May 4 Tokyo summit statement on the Chernobyl nuclear accident.

We, the Heads of State or Government of seven major industrial nations and the representatives of the European comunity, have discussed the implications of the accident at the Chernobyl nuclear power station. We express our deep sympathy for those affected. We remain ready to extend assistance, in particular medical and technical, as and when requested.

Nuclear power is and, properly managed, will continue to be an increasingly widely used source of energy. For each country the maintenance of safety and security is an international responsibility, and each country engaged in nuclear power generation bears full responsibility for the safety of the design, manufacture, operation, and maintenance of its installations.

Each of our countries meets exacting standards. Each country, furthermore, is responsible for prompt provision of detailed and complete information on nuclear emergencies and accidents, in particular those with potential transboundary consequences.

Each of our countries accepts that responsibility, and we urge the government of the Soviet Union, which did not do so in the case of Chernobyl, to provide urgently such infonnation, as our and other countries have requested. -

We note with satisfaction the Soviet Union's willingness to undertake discussions this week with the Director-General of the International Atomic Energy Agency (IAEA). We expect that these discussions will lead to the Soviet Union's participation in the desired post-accident analysis.

We welcome and encourage the work of the IAEA in seeking i

to improve international cooperation on the safety of nuclear i installations, the handling of nuclear accidents and their consequences, and the provision of mutual emergency assistance.

i Moving forward from the relevant IAEA guidelines, we urge the early elaboration of an international convention comitting the

, parties tn report and exchange information in the event of nuclear i emergeNics or accidents. This should be done with the least j possible delay, i

3 STATEMENT BY CORDELL REED, CHAIRMAN, IDCOR STEERING COMMITTEE CONCERNING THE ACCIDENT AT THE S0VIET PLANT THE NUCLEAR INDUSTRY THROUGH THE INDUSTRY DEGRADED CORE RULE-MAKING PROGRAM (IDCOR) HAS PERFORMED EXTENSIVE STUDIES OVER THE LAST SIX YEARS OF THE CONSEQUENCES OF A CORE MELTDOWN ACCIDENT I.N U.S. REACTORS. THIS WORK HAS COST OVER 24 MILLION DOLLARS AND WAS FUNDED BY 60 ORGANIZATIONS INCLUDING MOST NUCLEAR UTILITIES, NUCLEAR STEAM SUPPLY VENDORS, AND PAJOR ARCHITECT ENGINEERS. IT ENCOMPASSED MORE THAN 50 TECHNICAL TASKS AND UTILIZED 23 SEPARATE CONTRACTORS. THE IDCOR STUDIES ARE THE MOST EXTENSIVE EVALUATION OF NUCLEAR POWER PLANTS SAFETY EVER ATTEMPTED BY A SINGLE INDUSTRY PROGRAM.

THE STUDIES EVALUATED THE CONSEQUENCES OF CORE MELTDOWN ACCIDENTS OF SEVEN U.S. PLANT DESIGNS WHICH PROVIDES A REPRESENTATIVE CROSS SECTION OF U.S. PLANT DESIGNS. THESE STUDIES CONCLUDE:

(1) THE PROBABILITY DF A CORE MELTDOWN ACCIDENT IN U.S.

REACTORS IS EXTREMELY SMALL DUE TO THE CONSERVATIVE DESIGN AND REDUNDANT EMERGENCY CORE COOLING SYSTEMS.

(2) IN THE EVENT OF A CORE MELTDOWN, THE VAST MAJORITY OF CORE MELTDOWNS WOULD NEVER REACH THE CONTAINMENT BUILDING AND WOULD BE MAINTAINED IN A SAFE, STABLE CONDITION IN THE CONTAINMENT BUILDING.

Fo I h-1%-T5F E6 av IO s

a

.s 2 .

(3) IN THE HIGHLY IMPROBABLE CASE WHERE A CORE MELT 00WN WOULO REACH THE CONTAINMENT BUILDING,.IT WOULO ONLY OCCUR AFTER MANY HOURS. AS A RESULT, NO EARLY FATALITIES WOULD BE EXPECTED BECAUSE THERE WOULO BE SUFFICIENT TIME FOR EVACUATION.

(4) HOWEVER, SOME SMALL RISK IS CALCULATED TO REMAIN WITH RESPECT TO LATENT FATALITIES OVER A 30 YEAR PER100. THESE RISKS ARE EXTREMELY LOW. THE RISK OF LATENT CANCER FATALITIES FROM THE REFERENCED PLANTS STUDIED IS 1000 TIMES LOWER THAN THE ORAFT PROPOSED NRC SAFETY GOALS. THE RISKS FROM POTENTIAL SEVERE ACCIDENTS AT THESE PLANTS ARE ONLY ONE MILLIONTH OF THE NORMAL OCCURRING CANCER FATALITIES FOR THE POPULATION LIVING WITHIN 50 MILES OF THE PLANT.

AFTER REVIEWING THE NEWS REPORTS OF THE CORE MELT 00WN ACCIDENT AT THE SOVIET'S CHERNOBYL PLANT, 10COR STILL BELIEVES THEIR STUDY RESULTS ARE VALIO FOR U.S. PLANTS. THIS IS BECAUSE OF FUNDAMENTAL O!FFERENT DESIGN AND SAFETY PHILOSOPHIES THAT EXIST BETWEEN THE SOVIET AND U.S. REACTORS. UNLIKE THE SOVIET PLANTS, U.S. COMMCRCIAL REACTORS HAVE CONTAINMENT BUILDINGS AND NO GRAPHITE CORE THAT CAN BURN. ONE EXCEPTION !$ THE U.S. COMMERCIAL .

GRAPHITE MODERATED REACTOR IN COLORAD0' THAT IS Or A SUBSTANTIAL DIFFERENT DESIGN THAN THE SOVIET'S. THE 10COR PROGRAM WILL CONTINUE TO EVALUATE THE RESULTS FROM THE SOVIET UNION AND FACTOR THE INFORMATION INTO THE SAFETY REVIEW OF U.S. REACTORS.

Task Force Report on Soviet Nuclear Accident ,

Fact Sheet-Chernobyl SOVIET NUCLEAR ACCIDENT FOR RELEASE: 2:00 P.M., FRIDAY, MAY 2, 1986 CONTACT: DAVECOHEN(202)382-43$5 Radiation monitoring networks in the United States and Canada are continuing to analyze for airborne radioactivity daily. No increases in radioactivity above normal background levels have been detected in either country. Canadian officials intend to increase the sampling frequency of their milk monitoring network, which consists of 16 stations near population centers in southern Canada, to weekly beginning

-next week.

'It is believed that air containing radioactivity now covers much of Europe and a large part of the Soviet Union. The distribu-tion of radioactivity is likely to be patchy. Air containing radioactivity detected by aircraft at 5000 feet about 400 miles west of northern Norway is believed to have moved westward and now appears to be heading south or southeastward perhaps to return to western Europe. There is no independent confirmation of the radio-activity in the air moving eastward across Asia.

(A weather map should be attached to toda.ds Task Force Report.

If you do not have a copy, it can be picked up in the EPA press office, room 311, West Tower, 401 M St., S.W. (202) 382-4355.)

Environmental monitoring data have been provided by the Swedish government for the Stockholm area for April 28-30. Extrapolations of those data suggest that radiation exposure levels at the Chernobyl site would have been in a range from 20 rem to hundreds of rem whole-body for the two-day period over which most of the radiation release probably took place. Radiation doses for the thyroid gland have been estimated to be in a range from 200 rem to thousands of rem -

for the same period. These doses are sufficient to produce severe physical trauma including death. It should be emphasized that these are estimates subject to considerable uncertainty. The U.S. has as yet no information from the Soviet Union as to actual radiation levels experienced at the accident site.

l The Soviets have reported they have smothered the fire. We -

, still cannot confirm that the reactor fire in unit 4 has been  !

extinguished. There is evidence that the reactor or associated i

equipment continues to smolder. We also cannot confirm news i

! reports of damage at a second reactor, but the second hot spot l seen in the LANDSAT photos is not a reactor.  !

3, i Based on the fact that no harmful levels of radioactivity are j expected to reach the continental United States, it is highly

_ unlikely that potassium iodide (KI) will be needed to minimize the uptake of radioactive iodine from the Russian nuclear power .

i plant accident. KI, although relatively harmless, has been l 4 associated with certain allergic reactions; thus, since the use '

of KI is not without some risk to the population, the U.S. Public t

Health Service recomends against taking KI as a precautionary measure. Federal authorities do not believe there is any reason for concern at this time about the safety of either our domestic food or drug supplies. Nor should there be concern over imported

products already in the United States or on their way to the United States at the time of the nuclear accident in the Soviet i Union. 1

! The State Department is continuing efforts to obtain relevant

! infonnation from Soviet authorities on the nuclear accident and the potential health dangers that might be posed to individuals ,

4 in the Soviet Union and adjacent countries. State has noted, for example, recent statements issued by Polish authorities concerning 4

public health precautionary measures.

l The State Department is seeking more information from all the .

I governments in the region. The U.S. is sending experts to  !

L potentially affected areas for medical consultation and to provide i relevant expertise on which to make appropriate recommendations i with regard to the health of American citizens.

I i With the limited data at hand, the Departments of State and ,

i Health and Human Services have issued an advisory against travel

! to Kiev and adjacent areas. To minimize possible exposure to  ;

J- radioactive contamination, we also suggest that those in Eastern i i

Europe avoid milk and other dairy products. In addition. State  ;

is recomending that women of child-bearing age and children -

i should not travel to Poland until the situation is clarified.

The State Department is receiving reports from our European  :

The White House has established an Interagency Task Force to coordinate the Government's response to the nuclear reactor accident in Chernobyl. The Task force is under the direction of Lee M. Thomas, Administrator of the Environmental Protection Agency, with representatives from the White House, Department of State, EPA, Department of Energy, Nuclear Regulatory Comission, National Oceanic and Atmospheric Administration, U.S. Air Force, Department of Agriculture, Food and Drug Administration, Federal Emergency Management Agency, Department of Interior, Federal Aviation Administration, the U.S. Public Health Service, and other agencies.

PLEASE NOTE: THE EPA PRESS OFFICE WILL BE OPEN OVER THE WEEXEND FOR UPDATING. HOURS WILL BE FROM 10am TO 2PM. 202-382-4355.

He was surveyed in Moscow, where some clothing was confiscated and he was advised to launder the rest and to shower.

Oyster Creek believes that the traveler should be decontaminated and his clothing disposed of. Oyster Creek concerns are:

Do they have the authority to decontaminate the traveler and dispose of his clothing?

2. If they do, will his clothing affect their burial allotment?
3. What liabilities will they incur if they help?

Ichaus will make sure that Oyster Creek is talking to the right organization (Bureau an a stateof responsibility.
