Information Notice No. 84-07: DESIGN-BASIS THREAT AND REVIEW OF
VEHICULAR ACCESS CONTROLS
Addressees:
All nuclear power reactor facilities holding an operating license (OL) or
construction permit (CP), and certain fuel fabrication and processing
facilities using or possessing a formula quantity of special nuclear
material.
Purpose:
This information notice is provided to inform addressees of NRC concerns
regarding potential use of vehicle bombs by terrorists against nuclear
activities or facilities, and of actions NRC is taking and considering as a
result of these concerns. It is expected that licensees will review this
information for applicability to their activities. No specific action or
response is required at this time.
Description of Circumstances:
Recent publicized events indicate that U.S. installations in overseas areas
have become the target of terrorist groups using vehicle bombs. The
Executive Branch recently announced that security precautions at certain
government facilities in this country have been upgraded as a matter of
prudence. Also, as a matter of prudence, the NRC is considering revision to
the design-basis threat defined in 10 CFR 73.1.
Discussion:
Licensees are not required by 10 CFR 73 to protect against vehicle bombs,
however, it would appear appropriate for addressees to review their
vehicular access control equipment and procedures at this time. It would
also be prudent for addressees to examine their contingency plans and the
tactical measures to be employed by members of the security organization to
impede penetration of protected areas by unauthorized vehicles. In the
meantime, NRC has initiated a task to estimate the consequences of vehicular
attacks at nuclear facilities and to identify cost effective measures to
protect against such tactics.
