In the Matter of

NEBRASKA PUBLIC POWER DISTRICT Docket No. 50-298 (Cooper Nuclear Station)

)

EXEMPTION FROM SCHEDUL AR REQUIREMENTS OF 10 CFR 50.49(g)

The Nebraska Public Power District (NPPD/the licensee) is the holder of Facility Operating License No. DPR-46 which authorizes NPPD to cperate the Cooper Nuclear Station (CNS) at power levels not in excess of 2381 megawatts thermal, The facility is a boiling water reactor located at :he licensee's site in Nemaha County, Nebraska.

The license provides, among other things, that it is subject to all Rules, Regulations, and Orders of the Commission now or hereafter in effect.

II On February 22, 1983, the environmenkal qualification rule for electrical equipment important to safety for nuclear power plants,10 CFR 50.49, became effective.

Subsection (g) of 50.49 requires that each holder of an operating license issued prior to February 22, 1983, shall by May 20, 1983, identify the electrical equipment important to safety within the scope of the rule already qualified and submit a schedule for either the qualification or the replacement of remaining electrical equipment subject to the rule.

This schedule must establish a goal of final environmental qualification of the electrical equipment by the end of the second refueling outage after 5

7 3161765-7 % 4pp. f

(

2 March 31,1982, or by March 31,1985, whichever is earlier.

The rule also provides that the Director of the Office of Nuclear Reactor Regulation may grant requests for extensions of this deadline to a date no later than November 30, 1985, for specific pieces of equipment if these requests are filed on a timely basis and demonstrate good cause for such an extension, such as procurement lead time, task complications, and installation problems.

III l

On June 24, 1983, the licensee requested an extension from the dates specified in 10 CFR 50.49(g).

The Cooper plant is on a one-year refueling cycle, and went into an outage shortly after the March 1982 date.

Therefore, the end of the second refueling outage will occur in early September 1983. The licensee stated that additional time was needed because the rule expanded the scope of electrical equipment required to be qualified to a harsh environment, and the need to identify and qualify this additional equipment will require more time and another outage.

The licensee specifically requested extension until the end of its 1985 outage but no later tnar fovemoer 30, 1985.

I We have reviewed the licensee submittal and agree that good cause for a schedular extension of the rule exists for the following reasons:

the close proximity of the plant's first refueling outage to the effective date of the rule; the plant is on a one-year refueling cycle; and the expanded scope of the rule to include non-safety-related equipment [10 CFR 50.49(b)(2)]

and post-accident monitoring equipment [10 CFR 50.49(b)(3)]. However, since the licensee has not been able to complete identification of the specific equipeent for which a schedular exemption is needed, we are unable to grant l

l l

t

o C

3-the full extent of the licensee's request. Because we find, however, that the licensee is working in good faith to meet the rule, an extension to the end of the third refueling outage after March 31, 1982, can be granted.

This would place the licensee on approximately equal footing with plants operating on an 18-month refueling cycle. The licensee must complete qualification of all equipment by the end of the third outage but in any event no later than March 31, 1985 Requests for extension beyond that date must meet the specific criteria stated in 10 CFR 50.49(g).

IV.

4 Accordingly, the Commission has determined that, pursuant to 10 CFR

_50.12, an exemption is authorized by law and will not endanger life or property or the concon defense and security and is otherwise in the public i

interest. Therefore, the Connissior. hereby approves the following exemotion:

l Exemption is granted from the schedular requirement of Section 50.49(g)

J to extend the required date of final environmental qualification of electrical equipment from "the end of the second refueling outage after

)

i March 31,1982, or by March 31, 1985, whichever is earlier" to "the end of the third refueling outage after March 31, 1982 or by March 31, 1935, I

whichever is earlier."

e j

The ConrHssion has determined that the granting of this exemption will not result in any significant environmental impact and that, pursuant i
