guality Requirements for Meteorological Tower Equipment File:

89-A-056-026; 89-A-005-419.05 The purpose of this letter is to transmit a

change to the quality assurance program description contained in the Safety Analysis Report

'for Palo Verde.

This change may reduce the previous quality assurance commitments for the meteorological tower equipment.

Therefore, this change is being submitted in accordance with the requirements o'f 10CFR50.54(a)(3).

The information requested by 10CFR50.54(a)(3) is provided in the following paragraphs.

The proposed change clarifies the quality assurance requirements for the meteorological tower equipment.

The present Updated Safety Analysis Report (USAR) states that the activities of administration,

control, operation, maintenance, and inspection of the meteorological tower equipment are subject to the pertinent requirements of the quality assurance program.

However, this commitment exceeds the current regulatory requirements.

In Revision 2

of Regulatory Guide 1.97, the meteorological instrumentation is classified as a

Category 3

variable.

Category 3

instruments are only required to be "high-quality commercial, grade".

ANPP proposes to maintain the commitment to conduct system calibration in accordance with the pertinent requirements of the operational quality assurance program.

Other activities rel'ated to the meteorological equipment will no longer be subject to quality assurance requirements.

The affected pages o'f the Palo Verde USAR are attached.

ANPP believes that the

'roposed changes are in conformance with the applicable regulatory guidance.

In accordance with the requirements of 10CFR170.12(c),

an application fee of 9150.00 is attached.

Should you have any questions concerning this matter,.

please contact Mr. A. C. Rogers at (602) 371-4041.

v' PVNGS UPDATED FSAR METEOROLOGY Strip chart data.

when used, were manually reduced.

One 15-minute sample of strip data is used for each 1-hour data period available.

Average values of wind direction, wind speed, ambient temperature, temperature differential, and dewpoint are obtained by visually estimating a

mean for the 15-mi.nute sample of the analog traces.

The,precipitation trace cumula-tively records precipitation amounts and resets each quarter hour.

2.3.3.3 ualit Assurance Procedures The meteorological data c'ollection program at PVNGS is subject to detailed APS and NUS Corporation quality.assurance and quality control procedures.

The procedures involve daily examinations by

a. meteorologist of the digitally reduced

data, routine comparisons of the digital data with analog reduced

data, redundant data storage to mitigate data losses, detailed records keeping (data correc-tions. calculations, etc.), site specific work plans, and internal audits.

Calibrations f the meteorological system are subject to the APS quality assurance program.

2.3.3.4 Meteorolo ical'ata Recover The meteorological data recovery rates for the PVNGS meteoro-logical program (August 13, 1973 to August 13, 1978')

are listed in table 2.3-29

'he data recovery for wind data at the 3.5-foot level and 200-foot level was 97 and 94

, respectively, for the report period.

Data recovery of the dewpoint temperature was 94 data recovery for dT was 94 200'-35'ost of the data losses on the system are due to sensor mal-functions and calibrations.

Other than sensor problems.

periods of data loss on the digital system are due primarily The 2.3'-59

FOOTNOTE ii Meteorological system calibration is considered to be a quality-related activity and is subject to the pertinent requirements of the operational quality assurance program.

The meteorological equipment is classified as not quality-related.

This is in accordance with the Regulatory Guide 1.97, Rev. 2 requirements which require that Cat'egory 3 instrumentation be "high quality commercial grade".

Regulatory Guide 1.97 does not impose any quality assurance program controls on Category 3

instrumentation.
