FARLEY NUCLEAR PLANT ENGINEERING TECHNICAL PROCEDURE SERVICE WATER STORAGE POND PIEZOMETER WELL READINGS 1.0 Purpose This procedure specifies the testing required to obtain data for recording the water level in piezometer wells which are located at the Service Water Storage Pond.
The provisions of FNP-0-AP-24 are not applicable.
2.0 Acceptance Criteria 2.1 The Data recorded on the Data Sheets are forwarded to PGS-Licensing and Regulatory Compliance for plotting and evaluation.
In addition, results are evaluated by Southern Company Services.
Their evaluation is normally submitted within 30 days of the completion of the testing.
The evaluation letter includes recommendations for corrective action when appropriate.
Any water levels that have a differential of +/-5 feet in comparison to the previous reading are tested again.
Otherwise, no quantitative acceptance criteria exist.

4.4 1/10 ft3 calibrated mold to be supplied by PGTS-Civil.
4.5 Data Sheets from previous test, supplied by PGTS-Civil.
PGTS 5.0 Precautions and Limitations 5.1 The water level indicators used are capable of measuring up to 300 feet (Model No. DP.-7 60A) or 100 feet (Model No. 51453).
5.2 Approval of the Test Supervisor is required prior to performing procedure sections or steps out of sequential order.
Supervisor approval shall be documented on the data sheet.
5.3 IF a procedural step that required documentation is purposely not performed, and is not required, THEN "N/A" (Not Applicable) shall be entered in the sign off space.
IF the procedure or controlling work order does not provide specific instructions for "Not Applicable" steps, THEN the Test Supervisor will N/A the step not performed, document in the margin by the step the reason for the step being not applicable, and provide his signature and the date.
I l
5.4 Steps of the procedure with a designator (described below) in the left margin denote the requirement for the individual performing the step to provide his signature and date on the data sheet.
5.4.1 Designator PGTS, APCO Power Generation Services.
5.4.2 Designator SP, Systems Performance.
SP/PGTS 6.0 Prerequisites and Initial Conditions 6.1 PGTS-Civil has coordinated verk through the General Manager of Nuclear Support at Southern Nuclear.
6.2 Ensure that the data sheets from the previous test are attached to the procedure upon procedure closecut.
6.3 Performance of this procedure has been scheduled by FNP-SP.
i 6.4 Permission has been obtained from the Shift Supervisor to perform this procedure.

7.1 Preparation PGTS 7.1.1 Check the probe and battery to ensure that a i
positive response occurs when the probe comes in' contact with water.
l PGTS 7.1.2 Press the test button to check the condition f
of the battery.
i PGTS 7.2 Testing NOTE:
Signoffs for steps 7.2.2.1 thru 7.2.4 are located on Data Sheets 2A thru 4.
i i
7.2.1 Turn the probe power switch "on".
/
7.2.2 Read the wire marker to determine the depth j
of the probe at the point of needle
.j reflecting.
A subsidiary scale is needed to measure the distance from the top of the riser to the next mark.
~
(Mark distance - subsidiary scale reading =
Depth to Water)
?
I 7.2.2.1 (a) Record the current depth to water j
for each well on Data Sheet 2A, i
2B, 2C or 3.
j t
7.2.2.2 (b) For each well, note on Data Sheet i
t 2A, 2B, 2C, or 3 any' condition of deterioration, damage, missing parts, excessive vegetative growth, ant hills, animal burrows, or other unusual condition related to the well, the protective devices such as pipe frames and caps, or in the surrounding area.

FNP-0-ETP-4381 7.2.2.2 Record the previous depth to water for each well and calculate the difference and record both readings on Data Sheet 2A, 2B, 2C or 3.
Previous depth to water readings are obtained from data sheets which are supplied by PGTS.
(Current depth to water - Previous depth to water = Depth to water difference) r Acceptance Criteria: Depth to water difference is +/-5 feet.
7.2,2.3 IF the acceptance criteria was met, THEN proceed to Step 7.2.2.5.
7.2.2.4 IF the acceptance criteria was NOT i
met, THEN perform Steps 7.2.1 thru Step 7.2.2.2.
Continue testing until 2 consecutive tests agree and record that depth (not to exceed 4 retests).
7.2.2.5 Record the water elevation on Data Sheet 2A, 2B, 2C or 3.
r (Elev. Top of Riser - Depth to Water =
Water Elevation) 7.2.3 Record (on Data Sheet 4) the time it takes to fill a 1/103 ft. calibrated mold at the horizontal drain and right relief well.
Record the time in minutes and seconds.
