INTERNATIONAL RESPONSES TO JAPANESE PLUTONIUM PROGRAMS
EXECUTIVE SUMMARY

Abstract

Japanese plutonium programs have aroused considerable concern from a variety of 
sources abroad. These concerns have been raised by disparate individuals, nations 
and organizations and have persisted notwithstanding Japanese attention to safety 
and careful adherence to formal international requirements. This study explores 
these concerns and makes suggestions that could reduce them and benefit the 
international nuclear non-proliferation regime.

International apprehension over Japanese plutonium programs is fueled by their 
implications for nuclear proliferation, by the unconvincing nature of the official 
rationales behind the programs, and by lack of appreciation of background factors 
that are major drivers behind the programs. Stripped of caveats and qualifications, 
our explanation for these international concerns reduces to the following essentials.
First, proceeding with commercial-scale plutonium programs increases the 
likelihood that other countries will follow the Japanese example, perhaps with 
less physical security against theft by subnational groups or diversion for weapons 
use. Long-term R&D intended to maintain technology options as insurance against 
unfavorable energy developments, on the other band would not raise similar 
concerns.Second the extensive Japanese commitment to plutonium programs 
appears to be incommensurate with the benefits advanced in the official rationales 
for these programs. In an international climate in which safety and proliferation 
dangers of nuclear energy are considered by many to be of paramount importance, 
the official rationales of energy security, economic benefits, and environmental 
advantages are not convincing to away foreign observers.
Third, a set of background factors provides a relatively being explanation of these 
programs. These factors include local politics, the inertia of large organizations, 
industrial interests, and cultural factors. Insufficient appreciation of these 
background factors contributes to criticism of Japanese plutonium programs, 
especially in the light of proliferation risks and skepticism about the official 
rationales for the programs.

This study traces the implications of international responses to the Japanese 
programs and suggests ways to mitigate international concerns. Our primary 
recommendations involve modifications of existing programs rather than simple 
repackaging of existing initiatives. These modifications include diversifying 
aspects of the fuel cycle program, emphasizing long-term R&D. avoiding 
premature commercialization of plutonium, opening further the policy process, 
enhancing confidence-building measures, providing vigorous support for 
non-proliferation measures, and not encouraging commercial plutonium 
programs in other countries.
