ENGINEERING TECHNICAL PROCEDURE SERVICE WATER STORAGE POND DAM BIENNIAL INSPECTION FNP-0-ETP-4389 1.0 Purpose 1.1 The purpose of this procedure is to describe the regular biennial inspection of the service water pond dam at Farley Nuclear Plant.
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.
This inspection is designed to prevent operational problems related to the dam by helping to insure that its integrity is maintained, i
The provisions of FNP-0-AP-24 are not applicable.
2.0 Acceptance Criteria 2.1 Evaluation of the dam is based on an inspection performed by the Alabama Power dam inspection team, consisting of engineers selected based on experience and knowledge in the design, construction and operation of dams.
Otherwise, no quantitative acceptance criteria exists.
3.0 Corrective Action 3.1 Proper corrective action varies and depends on a thorough assessment of conditions by qualified engineers.
3.1.1 For any condition which does not present an immediate threat to the integrity of the J
structure or plant, the inspection team will include recommendations for the appropriate corrective action (s) in the inspection report.
3.1.2 For any condition which presents an imminent danger to the integrity of the structure or the plant, the condition will be immediately evaluated and discussed with the appropriate I
plant personnel.

Instructions NOTE: DESCRIBE ANY ABNORMALITIES IN THE REMARKS SECTION OF THE DATA SHEET.
4 8.1 Scope of Inspection 8.1.1 Inspection of the entire length of the embankment structure, along the downstream toe and along the top of the dam is made on foot.
The appurtenant intake and discharge structures are also examined during this
[
inspection.
Inspection of the spillway-i channel is made at various points by vehicle.
PGS 8.2 Inspection 8.2.1 In the inspection of the embankmen*,
particular attention is given to detecting i
signs of seepage, erosion, differential i
settlement, displacement, cracking, or animal burrows, fire, ant hills, bushes and j
small trees on the embankment slopes,
~
ungrassed areas, and water ponding areas or other undesirable conditions along the roadway surface.
The rip rap on the upstream slope is inspected for signs of movement, excessive bush and tree growth.
Presence of one or more of these conditions to an excessive extent could indicate slope instability, s
8.2.2 Permanently installed instrumentation used h
to measure the performance of the structure is inspected for any. obvious changes or l
indications of improper functioning.
Instrumentation protective devices including above ground piping frames, covers and caps are inspected for damage,. deterioration, missing parts, and other abnormal conditions.
8.2.3 Appurtenant concrete structures are examined I
for structural cracking, deterioration, i
obstruction, settlement or other' conditions that could eventually impose operational j
constraints.
8.2.4 The unlined spillway channel is examined to verify that there are no significant obstructions of flow.

8.2.5 Gravity relief well manholes and the chimney drain central manhole are entered and 6
inspected for obstructions, deterioration, improper functioning or other conditions affecting proper operation.
8.2.6 Areas noted in previous biennial reports as being in need of corrective action or maintenance are re-inspected to be sure the conditions noted have been corrected and have not recurred.
8.3 Documentation PGS 8.3.1 Following the inspection, a meeting will be held with FNP-SP to report observations made i
during the inspection.
8.3.2 A final report of observations made during the inspection will be transmitted to the General Manager of Nuclear Support at Southern Nuclear.
9.0 Restoration SP 9.1 Shift supervisor notified of completion of inspection.
