Docket No. 50-313 Arkansas Nuclear One,. Unit No.1
-0RDER FOR MODIFICATION OF LICENSE I.
2-The Arkansas Power & Light Conpany (licensee) is the holder of Facility Operating License No. DPR-51, which authorizes the operation of the Arkansas Nuclear One, Unit No. I at steady state reactor power levels not in excess of 2568 megawatts. thermal (rated power).
The facility consists of a pres-surized water reactor located at the licensee's site in Pope County, Arkansas.
II.
On November 4,1977, the Union of Concerned Scientists (UCS) filed with the Comission a " Petition for Emergency and Remedial Relief." The petition sought action in two areas:
fire protection for electrical cables, and environmental qualification of electrical components.
By Memorandum and Order dated April 13,1978 (7 NRC 400), the Comission denied certain aspects of the petition and, with respect to.other aspects, ordered the NRC staff to take several related actions.
UCS filed a Petition for Reconsideration on May 2,1978.
By Memorandum and Order, dated May 23, 1980, the Comission reaffirmed its April 13, 1978 decision 1

However, the.
Comission's May 23, 1980 decision directed licensees and the NRC staff to undertake certain actions.
With respect to environmental _ qualification of safety-related electrical-equipment, the Comission determined that the provisions of the two staff. documents - the Division of Operating Reactc s " Guidelines for r
Evaluating Environmental Qualification of. Class lE Electrical Equipment
~
in Operating Reactors" (D0R Guidelines) and NUREG-0588, "Interir. Staff-p P
~
Position on Environmental Qualification of Safety-Related Electrical Equipment," December 1979 " form the requirements which licensees and L
applicants must meet. in order to satisfy-those aspects of 10 CFR Part
~
50, Appendix A General Design Criterion'(GDC-4), which relate to envi-ronmental qualification of_ safety-related electrical equipment." The i
Commission ~ directed, forrreplacementjarts in operating plants, "unless
~
y there are' sound' reasons to the contrary,-the 1974 standard in fluREG-0588 will apply." The Comission also directed the--staff to complete its 1
-review of the information sought from licensees by Bulletin 79-01B and f
to complete.its. review of environmental qualification of safety-related L
electrical equipment..in all operating plants, including the_ publication
_of Safety Evaluation Reports, by February 1,1981.
The Comission l-1__
' BulleU 79-018.was not sent,to licensees for< plants under review as-part:of y ie staff's Systematic Evaluation Program.~ The information
- s'ought. by Bulletin '79-01B was requested. from these licensees by a u
series of-letters and meetings duri'ng the months of February and March, 1980.'

imposed 'a deadline 'that, "by.no later than June 30, 1982-all safety'--
related electrical equipment in all operating plants shall.be'qualifled
'to the DOR Guidelines.or NUREG-0588." ~The Comission requested the staff to, " keep the Comission and the public apprised of any further
~
findings.of incoglete environmental qualification of. safety-related.
. electrical equipment,' along with. corrective actions taken or planned,"
and requested the? staff to_ provide bi-monthly progress reports to the Comi ssion. '
The Comission further. directed the staff: to add certain documentation requirements to each license after the specific ~ requirements were approved by the Comission. The Comission also pointed.out that the various deadlines imposed in its Order, "do.not excuse a-licensee from the obligation to modify or' replace inadequate equipment promptly "
III.
The 'information developed during this proceeding emphasizes the iinportance of adequate documentation, the prompt cogletion of the review of environ-mental qualification of-safety-related electrical equipme'nt, and the prompt completion of!any plant modification needed to assure conformance
~
r with the D0R Guidelines or NUREG-0588. A significant aspect of. this_ review lis' the timely submittal 'of environmental qualification information oy
.the operating plant licensees-to enable the staff to complete its review -
~
in accordance with the Comission's.0rder. - The stiff has a program presently underway to reevaluate, using the 00R Gui.delines and NUREG-4 0588, the' qualifications of safety-related electrical equipment _ exposed Ib <
_u
f to environments that nay exist following postulated accidents.
These accidents are Loss of Coolant Accident and Main Steam Line Break inside containment, and High Energy Line Breaks inside and outside centainment.
In this connection the licensee was requested by 1&E Bulletin 79-01B of January 14, 1980 to provide a detailed review of the environmental qualification of Class lE electrical e mipment.
This review was to include all equipment required to function under postulated accident conditions, both inside and outside the primary containment, and ecognize all conditions specified in the bulletin.
Evidence of qualification together with methods and justification, was requested.
Clarification was provided by supplemental information, briefings, and
'n some cases, meetings with the licensee.
Timely completion of the staff's review of environmentai qualification of electrical equipment and timely completion of needed modifications by the licensee is equired to provide continuing reasonable assurance of public health and safety.
Such completion is dependent on the prompt receipt of a conplete response by the licensee to the staff's requests for information.
However, the licensee's response, to date, is incomplete.
Therefore, I have concluded that the putlic health, safety, and interest recuire that a firm schedule for the timely submission of all the information previously requested by the staff should be established by Order effective immediately.
