Arkansas Nuclear One - Unit 2 Docket No. 50-368 License No. NPF-6 Technical Specification Change Requests for Remote Shutdown Panel Instrumentation and Hydrogen Analyzer Calibration Gentlemen:
Attached are Technical Specification change requests for your review and approval. These changes are being requested to accommodate design and surveillance requirements resulting from the installation of new equipment, and, as such, are judged to have no safety or environmental significance.
In accordance with 10CFR50.92(c), we have determined the proposed amendment as having No Significant Hazards Considerations (NSHC), and to satisfy the Sholly provisions we are including the basis of our NSHC determination as part of this amendment package.
Also, a copy of this amendment package has been sent to Mr. E. Frank Wilson, Director, Division of Environmental Health Protectior., State Department of Health.
The circumstances of this proposed amendment are neither exigent nor emergency; however, expeditious handling is requested.
Pursuant to the requirements of 10CFR170.22, we have determined these changes to be a Class II amendment, as they involve no significant safety or environmental determination. Accordingly, a check in the amount of
$1,200.00 is remitted.
Very truly yours, L72$42 W

PROPOSED REVISION OF ANO-2 TECHNICAL SPECIFICATION 4.6.4.1.b AND TABLE 3.3-9 BASES FOR CHANGE AND EVALUATION OF EFFECT ON PLANT OPERATION Technical Specification 4.6.4.1.b Hydrogen Analyzer Surveillance Requirements Specification 4.6.4.1 presently requires each hydrogen analyzer to be calibrated "by performing a CHANNEL CALIBRATION using sample gases containing:
a.
Zero volume percent hydrogen, balance nitrogen, and b.
Four volume percent (nominal) hydrogen, balance nitrogen."
This specification reflects the capabilities of the previous hydrogen analyzer system.
The current hydrogen analyzers allow a greater calibration range, as noted in Inspection Report 368/81-24.
Pursuant to open item 368/8024-06 of that inspection report, we request Specification 4.6.4.1.b be changed to reflect the capabilities of the new analyzers, i.e., the specification should allow calibration using a sample gas containing ten volume percent (nominal) hydrogen with the balance being nitrogen.
This change has no effect on plant safety or operation.
Technical Specification Table 3.3-9 Remote Shutdown Monitoring Instrumentation Table 3.3-9 presently requires measurement ranges for various instruments for remote shutdown monitoring purposes.
It is apparent this information should be deleted, as Specification 3.3.3.5 requires the table to reflect the number of instrumentation channels required to be operable, and that readouts be displayed external to the control room.
The measurement ranges of that equipment do not contribute to the basis of the technical specification, which is to achieve and maintain hot standby.
In order to eliminate the need and expense required to update this table when modifications are made to equipment, we recommend this information be deleted as it is unnecessary and has no effect on plant safety or operation.
No Significant Hazards Consideration The proposed amendment request does not involve a No Significant Hazards Consideration (NSHC) because:
a.
Operation of ANO-2 in accordance with this change would not involve a significant reduction in a margin of safety, a significant increase in the possibility or consequences of an accident previously evaluated, nor would it introduce the possibility of a previously unanalyzed accident; and
b.
The proposed amendment matches the example shown below (Ref: DLOP 228, Federal Register, Vol. 48, p. 14870).
(i) A purely administrative change to technical specifications:
for example, a change to achieve consistency throughout the technical specifications, correction of an error, or a change in nomenclature.
Basis The proposed Technical Specification 4.6.4.1.b reflects the capabilities of the current hydrogen analyzer system.
As this system allows a calibration range with a greater concentration of hydrogen, the new system calibration is more accurate than the previous system.
The proposed specification corrects the specification to enable calibration with this increased hydrogen concentration.
The proposed Technical Specification Table 3.3-9 reflects _ the instrumentation requirements pertaining to readout location and system operability for achieving remote shutdown.
It is apparent the measurement ranges listed in the present Table 3.3-9 need to be deleted as Specification 3.3.3.5 requires the table to reflect the number of instrumentation channels required to be operable, and that readouts be displayed external to the control room.
the measurement ranges of that equipment do not contribute to the basis of the technical specification, which is to assure instrumentation is operable that is necessary to achieve and maintain hot standby.
The information in proposed Table 3.3-9 is deemed adequate to address the intent of the specification.
