NUCLEAR REGULATORY COMMISSION
[Docket No. 50-22]
CBS Corporation, Westinghouse Test Reactor; Environmental
Assessment and Finding of No Significant Impact
The U.S. Nuclear Regulatory Commission (the Commission) is
considering the issuance of a license amendment to the CBS Corporation
(the licensee) (formerly Westinghouse Electric Corporation) that would
allow
[[Page 52309]]
decommissioning of the Westinghouse Test Reactor (WTR) located in
Westmoreland County, Pennsylvania.
Environmental Assessment
Identification of the Proposed Action
The WTR Facility is located in western Pennsylvania, near the town
of Madison, and is on a site called the Waltz Mill site. The reactor
operated from 1959 to 1962, primarily as a research and testing
reactor. The facility was placed in a condition equivalent to a status
later defined by the U.S. Nuclear Regulatory Commission (NRC) as
``SAFSTOR'' (safe storage) after it was shut down in 1962, and the
operating license was converted to ``Possession Only'' (Amendment No.
2, dated March 25, 1963). All fuel and some of the reactor internal
contents have been removed from the reactor vessel and from the Waltz
Mill site.
The licensee submitted a decommissioning plan in accordance with 10
CFR 50.82(b) on July 31, 1997, as supplemented on March 20 and July 10,
1998. Decommissioning, as described in the plan, will be accomplished
by removal and disposal of the remaining reactor vessel internal
contents, the reactor vessel, and the biological shield. The balance of
the WTR facility components and the remaining residual radioactive
materials will be transferred to the existing SNM-770 license at the
Waltz Mill site. There are no radiological limits applicable to the
transfer of structures, materials, and equipment to the SNM-770
license, other than the radioactive materials possession limits
specified in the SNM-770 license.
The licensee submitted a Decommissioning Environmental Report on
March 20, 1998, which addresses the actual or potential environmental
impacts resulting from the decommissioning of the WTR Facility,
including decontamination, dismantlement, and site restoration
activities.
Opportunity for a hearing was afforded by a ``Notice of Proposed
Issuance of a License Amendment and an Order Authorizing Disposition of
Component Parts, Termination of Facility License, and Opportunity for
Hearing'' published in the Federal Register on October 21, 1997 (62 FR
54656). There were no requests for a hearing.
Need for the Proposed Action
The proposed action is necessary because of Westinghouse Electric
Corporation's 1962 decision to cease operations permanently at the WTR.
As specified in 10 CFR 50.82, any licensee may apply to the NRC for
authority to surrender a license voluntarily and to decommission the
affected facility. Further, 10 CFR 51.53(d) stipulates that each
applicant for a license amendment to authorize decommissioning of a
production or utilization facility shall submit with its application an
environmental report that reflects any new information or significant
environmental change associated with the proposed decommissioning
activities. Also, decommissioning the WTR and transferring the residual
radioactivity and remaining WTR facilities to the SNM-770 license is to
allow efficient management of the Waltz Mill site under one license.
Environmental Impact of the Proposed Action
All decontamination will be performed by trained personnel in
accordance with previously reviewed procedures and will be overseen by
experienced health physics staff. Solid and liquid waste will be
removed from the facility and managed in accordance with NRC
requirements. The WTR staff has calculated that the collective dose
equivalent to the WTR staff for the project will be less than 0.39
person-sievert (39 person-rem, Decommissioning Plan, July 25, 1991,
page 2-29). The maximum calculated public exposure, to the most exposed
person, from the planned decommissioning of the WTR would be less than
1 x 10-5 sievert per year (1 mrem per year, Westinghouse
letter, March 20, 1998, page 9).
The above conclusions were based on all proposed operations being
carefully planned and controlled, all contaminated components being
removed, packaged, and shipped offsite or controlled under SNM-770.
Furthermore, the existence of radiological control procedures that will
be in place will help ensure that releases of radioactive wastes from
the facility are within the limits of 10 CFR Part 20 and are as low as
reasonably achievable (ALARA).
Based on the review of the specific proposed activities associated
with the dismantling and decontamination of the WTR facility, the NRC
staff has determined that there will be no significant increase in the
amounts of radioactive effluents that may be released offsite, and no
significant increase in occupational or public radiation exposure.
With regard to nonradiological impacts, the proposed action will
not result in a change in nonradiological plant effluent and will have
no other nonradiological impact.
Accordingly, the Commission concludes that there are no significant
environmental impacts associated with the action.
Alternatives to the Proposed Action
The four alternatives available for disposition of the WTR are:
DECON, SAFSTOR, ENTOMB, and no action. These alternatives are defined
as follows:
DECON is the alternative in which the equipment, structures, and
portions of the facility and site containing radioactive contaminants
are removed or decontaminated to a level that permits the property to
be released for unrestricted use shortly after cessation of operations.
SAFSTOR is the alternative in which the nuclear facility is placed
and maintained in a condition that allows the nuclear facility to be
safely stored and subsequently decontaminated (deferred
decontamination) to levels that permit release for unrestricted use.
ENTOMB is the alternative in which radioactive contaminants are
encased in a structurally long-lived material, such as concrete, the
entombed structure is appropriately maintained and continued
surveillance is carried out until the radioactivity decays to a level
permitting release of the property for unrestricted use.
The licensee has evaluated the pros and cons of these alternatives
in a letter dated March 20, 1998, and has given acceptable
justification for proposing the modified DECON approach. It is
considered a modified DECON approach because the WTR facility will not
be released for unrestricted use but will be transferred to an existing
NRC materials license. The principal reasons for this selection are as
follow:
1. The facility has been in the SAFSTOR mode for 35 years and the
majority of benefit from radioactive decay has already been realized.
2. Considering the potential for future escalation in the cost of
radioactive waste burial and demolishment activities, the modified
DECON alternative is most beneficial now.
3. Integrating the remaining WTR area into the existing materials
license at the site will improve the efficiency of the decommissioning
activities for the entire site at Waltz Mill. Key individuals that will
be performing the decommissioning activities have experience from other
decommissioning and remediation projects, including performing the
remediation of the Waltz Mill Site.
[[Page 52310]]
The only alternative to the proposed dismantling and
decontamination activities is to maintain possession of the reactor in
the SAFSTOR mode. This approach would include monitoring and reporting
for the duration of the safe storage period. However, the licensee has
determined that it would be more efficient to terminate the reactor
license by removing the remaining reactor vessel internal contents, the
reactor vessel and the biological shield, and transferring the balance
of the facility components and remaining residual radioactivity to the
existing SNM-770 license.
Alternative Use of Resources
This action does not involve the use of any resources not
previously considered in the Environmental Report submitted on March
20, 1998, for the WTR.
Agencies and Persons Contacted
In accordance with its stated policy, on June 23, 1998, the NRC
staff consulted with the Pennsylvania State Official, Ray Woods, of the
Bureau of Radiation Protection, Pennsylvania Department of
Environmental Protection, regarding the environmental impact of the
proposed action. There was no objection to the conclusions reached in
the environmental assessment.
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 July 31, 1997, March 20, and July 10, 1998,
which are available for pubic inspection at the Commission's Public
Document Room, the Gelman Building, 2120 L Street, NW, Washington, DC
