SUBJECT:
Arkansas Nuclear One - Unit 2 Docket No. 50-368 License No. NPF-6 Proposed Technical Specifications for the Sodium Hydroxide Addition System Gentlemen:
Attached is a proposed change to Technical Specification 4.6.2.2.e.
The purpose of this change is to clarify the intent of this specification.
Specification 4.6.2.2.e is contained in the Technical Specifications to ensure an adequate flow path from the discharge of the sodium hydroxide additive pump to the containment spray pump discharge.
As it is currently written the specification could be misinterpreted to require testing of the sodium hydroxide additive pumps as part of this surveillance.
A pump test during this surveillance is unnecessary, since these pumps are verified operable monthly per ASME Section XI requirements.
Therefore, AP&L proposes to revise this specification to more clearly state the requirement.
In accordance with 10CFR50.92(c), we have determined the proposed amendment to have no Significant Hazards consideration (SHC) and are including the basis of our SMC determination as an attachment to the proposed change.
Also, a copy of this amendment package is being forwarded to Mr. E. Frank Wilson, Director, Division of Environmental Health, State of Arkansas.
The circumstances of this amendment are not exigent or emergency.
- However, j
we do request your prompt review as this test is required during our upcoming refueling outage which is scheduled to begin in March.

e DESCRIPTION OF AMENDMENT REQUEST The current Technical specification, 4.6.2.2. 3, requires that every five years the flow rate through the sodium hydrox de additive path be verified to be at least 14 gpm.
The purpose of this specification is to ensure
~
adequate piping capacity to deliver the required Na0H to the containment spray line.
The sodium hydroxide additive pumps flows and their suction piping-flows are verified once per month per ASME Section XI requirements.
.The sodium hydroxide additive pumps are rated to provide 13 gpm i 7 percent.
This flow rate is discussed in section 6.2.2.2.1.8.2 and 6.2.3.3.1.3 of the ANO-2 Safety Analysis Report.
As it is currently written Technical Specification 4.6.2.2.e could be misinterpreted to require these pumps to be tested as part of the 5 year surveillance test, thus requiring them to provide a flow rate of 14 gpm which is beyond their capability.
Therefore, AP&L'is proposing to revise this specification to clarify its intent.
BASIS FOR PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION The proposed ~ amendment does not involve a Significant Hazards Consideration as it does not: involve a'significant increase in the probability or consequences of an accident previously evaluated.
Additionally, it does not introduce the possibility of a previously unanalyzed accident or involve a significant reduction in the margin of safety.
The Commission has provided guidance concerning the application of these standards by providing certain examples (48FR14870).
The proposed amendment matches example (i) "A purely administrative change to technical Lspecifications:
for example,_a change to achieve consistency throughout the technical specifications, correcti~on of an error, or a change in nomenclature." as it clarifies the intent of the Technical Specifications.
