158. Memorandum From Jan Lodal and David Elliott of the National Security Council Staff to Secretary of State Kissinger1

SUBJECT

  • Approach to South Korea on Reprocessing

[Omitted here is language identical to the initial part of Document 156.]

Regional Factors

If Korea begins to build a reprocessing plant in addition to the essential nuclear reactors we have agreed to supply, it will be widely assumed that it is seriously working on a nuclear weapons program. This perception would be potentially destabilizing in all of northeast Asia. North Korea would certainly press its allies for a similar capability, and both China and the Soviet Union might see potential nuclear threats to their own territory. Perhaps most important, development of nuclear weapons in Korea could tip the balance on proliferation in Japan.

Korean Intentions

Korea’s policy towards future development of a nuclear weapons capability seems fairly clear from intelligence regarding their armament program plans and from Park’s statement indicating that exercise of the nuclear option would depend on the continuation of U.S. security guarantees. Unfortunately, this Korean attitude is well-known in Congress and in the international arms control community. It will make it very difficult for the U.S. to continue normal civil nuclear commerce with Korea unless some specific protective measures are taken.

Reprocessing will not be necessary for South Korea’s nuclear power economy for several years and, in view of current controversy over [Page 522] the dangers of plutonium recycle, perhaps not for the foreseeable future. Both officials concerned with civil power development and those in favor of weapons production could probably be persuaded to defer the reprocessing effort, if necessary, to avoid jeopardizing acquisition of essential nuclear power reactors. We are pessimistic about longer term prospects, however, since the basic incentives for ROK nuclear weapons development will remain and they could either approach another supplier or eventually build their own reprocessing plant.

Korean Assurances

Korea has taken some steps recently in order to reassure us and others that its civil program is for peaceful purposes. They ratified the NPT when Canada made it a condition of acquisition of Canadian reactors, they recently accepted our tortured interpretation of our bilateral nuclear agreement that gives the U.S. veto rights on reprocessing of spent fuel from U.S. supplied reactors, and have provided similar assurances to Canada.

The Koreans undoubtedly have their limits, though, and the request from the U.S. for them to forego a planned reprocessing plant may approach that limit. Compounding this is the fact that they might also have to pay certain termination costs as discussed below.

The French Connection

The reprocessing plant that the Koreans are planning to acquire is of French origin. In a bilateral discussion prior to the nuclear suppliers conference we told the French that we were considering approaching the Koreans on this issue. They replied that if we succeeded in persuading the ROK to cancel its plans, they would have no objection provided that their reprocessing firm, St. Gobain, would be reimbursed for its $4 million in expenditures to date.

Implications for Non-Proliferation Policy

In reaching your decision on this issue, you should also consider its implications for our overall non-proliferation policy. As a result of FRG and French opposition, it is now clear that the Nuclear Suppliers Conference will result in controls on reprocessing that are less stringent than those in the FRG-Brazil nuclear accord and considerably less stringent than those we would impose on South Korea. In a recent bilateral discussion, the FRG informed us that they would wait until after the conclusion of the Suppliers Conference to finalize their umbrella agreement with Iran probably with the expectation that we would not oppose exports which were in accordance with the Suppliers’ agreement. Similarly, following the conclusion of a Suppliers’ agreement, it is conceivable that the ROK would approach another supplier [Page 523] such as the FRG and purchase a reprocessing plant under the agreed guidelines and we would then find it more difficult to interfere.

The real question as we work toward the goals of conclusion of a Suppliers Agreement, of strengthened IAEA safeguards and of increased NPT ratification is whether we will be willing to accept these as adequate controls both in terms of permitting U.S. exports on this basis and not objecting to bilateral arrangements between other suppliers and client states. In this regard, a comprehensive review of our non-proliferation policy is in progress in the VPWG and may serve as a useful basis for determining the extent to which we should continue to play an activist role in bilateral approaches rather than being content with the international regulatory mechanisms we are developing. However, this study will not be completed in time to serve as a basis for your decision on the Korean approach.

Options

The State proposal would have the advantage of closely following the Canadian démarche and would utilize our special leverage to exert maximum pressure on the ROK to abandon its plans. It would also be timely, and if the ROK agrees, would improve the prospects for pending congressional approval of the Export-Import Bank loan and Nuclear Regulatory Commission licensing of fuel shipment for the KORI–I reactor. The approach would have some risk, however, of antagonizing the Koreans and, through public disclosure, irritating the French who have already complained about publicity on the Suppliers Conference.

If successful, the question would also remain of who would reimburse the French for their four million dollars in development costs. On the basis of a preliminary examination, we have not identified any reasonable method of paying the French directly—which would be interpreted in Congress as “buying them off,” or of compensating the Koreans through our AID or Military Assistance (they are already unhappy over reduced amounts in the latter program). Thus, it appears that we would have to either force the Koreans to absorb these costs or ignore the French demand at the risk of losing their cooperation in the Suppliers Conference.

Alternatively, we could rely on Korea’s NPT obligations—including safeguards in its facilities and nuclear explosive deployment prohibitions, their assurances that they will not reprocess fuel from Canadian or U.S. reactors, and additional barriers coming out of the Suppliers’ Agreement, to satisfy our concerns. Unfortunately, such undertakings can be considered as mere “paper assurances” and some elements of Congress see it in these terms. In addition, if the ROK proceeds with this reprocessing plant, its neighbors would assume it is seriously working towards a nuclear weapons capability.

Your Decision

_______ That we continue bilateral efforts to deter ROK acquisition of a reprocessing plant (and forward the instruction cable to Seoul as the next step).

_______ That we make no further effort to deter their acquisition of a reprocessing plant, and rely instead on the ROK’s NPT obligations, IAEA safeguards and Suppliers Conference controls to ensure that they do not develop nuclear weapons.

Jack Froebe concurs.
