Faced with mounting safety problems in its military production reactors, the Energy Department will soon ask Congress to fund the construction of at least one new multibillion dollar tritium production reactor. Energy estimates that building such a reactor could take ten years, and it says that in the interim it needs to continue producing tritium at the Savannah River reactors. In fact, it plans to resume operating its Savannah River reactors at full power as soon as possible. The United States must keep producing tritium if the US-Soviet nuclear arms race continues its present course. If the arms race continues, the Energy Department has two basic options: it could run the Savannah River reactors for several more decades or it could use these reactors until it has built a new one. Operating the Savannah River reactors at full or low power may be risky, even if they undergo extensive safety modifications, since no one knows at what power these reactors can be operated safely. Despite these pressing issues, most of the substantive debate about the role of tritium in nuclear weapons and the requirement for more tritium production is taking place in secret. The public debate largely ignores the broader questions of whether the United States needs to produce tritium and what impact possible agreements reducing nuclear arsenals might have on US tritium requirements.
