This bill proposes the establishment of a National and Nuclear Risk Reduction Center (NNRRC) within the Department of State, reporting directly to the Under Secretary for Arms Control and International Security. The primary function of the NNRRC will be to operate a 24-hour government-to-government communications center, facilitating the exchange of notifications required by bilateral and multilateral arms control and confidence-building agreements. The NNRRC will also be responsible for translating and disseminating incoming and outgoing notifications to appropriate Federal agencies, especially for time-sensitive operational alerts. Furthermore, it will advise on communication issues for new agreements, provide technical assistance to foreign governments on national communication systems, and ensure the continuous availability of linguists proficient in Mandarin Chinese and Russian for technical arms control matters. The center is also tasked with establishing protocols for interagency coordination.
