NUCLEAR REGULATORY COMMISSION
[Docket No. 50-261]
Carolina Power & Light Company (H.B. Robinson Steam Electric
Plant Unit No. 2), Environmental Assessment and Finding of No
Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an exemption from the requirements of 10 CFR
70.24 to Carolina Power & Light Company (CP&L or the licensee) for
operation of the H. B. Robinson Steam Electric Plant, Unit No. 2 (HBR)
located at the licensee's site in Darlington County, South Carolina.

Environmental Assessment
Identification of Proposed Action
The proposed action would exempt the licensee from the requirements
of 10 CFR 70.24(a), which requires in each area in which special
nuclear material is handled, used, or stored a monitoring system that
will energize clear audible alarms if accidental criticality occurs.
The proposed action would also exempt the licensee from the
requirements to maintain emergency procedures for each area in which
this licensed special nuclear material is handled, used, or stored to
ensure that all personnel withdraw to an area of safety upon the
sounding of the alarm, to familiarize personnel with the evacuation
plan, and to designate responsible individuals for determining the
cause of the alarm, and to place radiation survey instruments in
accessible locations for use in such an emergency.
The proposed action is in accordance with the licensee's
application for exemption dated April 23, 1997, as supplemented by
letter dated August 27, 1997.
The Need for the Proposed Action
The purpose of 10 CFR 70.24 is to ensure that, if a criticality
were to occur during the handling of special nuclear material,
personnel would be alerted to that fact and would take appropriate
action. At a commercial nuclear power plant, the inadvertent
criticality with which 10 CFR 70.24 is concerned could occur during
fuel handling operations. The special nuclear material that could be
assembled into a critical mass at a commercial nuclear power plant is
in the form of nuclear fuel; the quantity of other forms of special
nuclear material that is stored on site is small enough to preclude
achieving a critical mass. Because the fuel is not enriched beyond 5.0
weight percent Uranium-235 and because commercial nuclear plant
licensees have procedures and design features that prevent inadvertent
criticality, the staff has determined that it is unlikely that an
inadvertent criticality could occur due to the handling of special
nuclear material at a commercial power reactor. The requirements of 10
CFR 70.24(a), therefore, are not necessary to ensure the safety of
personnel during the handling of special nuclear materials at
commercial power reactors. However, an exemption to 10 CFR 70.24(a) is
needed to permit a deviation from these requirements.
Environmental Impacts of the Proposed Action
The Commission has completed its evaluation of the proposed action
and concludes that the proposed action involves features located
entirely within the protected area as defined in 10 CFR Part 20.
The proposed action will not result in an increase in the
probability or consequences of accidents or result in a change in
occupational or offsite dose. Therefore, there are no radiological
impacts associated with the proposed action.
The proposed action will not result in a change in nonradiological
plant effluents and will have no other nonradiological environmental
impact.
Accordingly, the Commission concludes that there are no
environmental impacts associated with this action.
Alternatives to the Proposed Action
Since the Commission has concluded that there is no measurable
environmental impact associated with the proposed action, any
alternatives with equal or greater environmental impact need not be
evaluated. As an alternative to the proposed exemption, the staff
considered denial of the requested exemption. Denial of the request
would result in no change in current environmental impacts. The
environmental impacts of the proposed action and the alternative action
are similar.
Alternative Use of Resources
This action does not involve the use of any resources not
previously considered in the ``Final Environmental Statement Related to
the Operation of H.B. Robinson Nuclear Steam Electric Plant, Unit 2,''
dated April 1975.
Agencies and Persons Consulted
In accordance with its stated policy, on February 10, 1998, the
staff consulted with the South Carolina State official, Virgil Autry,
South Carolina Department of Health, Bureau of Radiological Health and
Environmental Control. The State official had no comments.
Finding of No Significant Impact
Based upon the environmental assessment, the Commission concludes
that the proposed action will not have a significant effect on the
quality of the human environment. Accordingly, the Commission has
determined not to prepare an environmental impact statement for the
proposed action.
For further details with respect to the proposed action, see the
licensee's letters dated April 23 and August 27, 1997, which are
available for public inspection at the Commission's Public Document
Room, which is located at The Gelman Building, 2120 L Street, NW.,
Washington, DC, and at the local public document room located at the
Hartsville Memorial Library, 147 West College Avenue, Hartsville, South
Carolina 29550.
Dated at Rockville, Maryland, this 2nd day of February 1998.
For the Nuclear Regulatory Commission.

Project Manager, Project Directorate II-1, Division of Reactor
Projects--I/II, Office of Nuclear Reactor Regulation.
