The following describes various aspects of the licensee's program:
A long term FAC program has been implemented at Surry.
The
licensee's method of predicting which systems are most
susceptible to FAC is EPRI CHECMATE Codes.
The licensee's FAC program includes the systems that have
been predicted to be susceptible to FAC.
The model ranks
each system's components according to their FAC
susceptibility.
The licensee's primary basis for selecting components for UT
inspection at the next outage is the results from the
predictive analysis.
Engineering judgement, results of
predictive analysis, industry experience and results from
previous UT inspections are used to select supplemental
inspection locations.
The following systems are included in the licens~e's FAC
program:
Condensate
Feedwater Heater Drains
Moisture Separator Drafns
_
Moisture Separator Reheater Drains
,
Steam Generator- Slowdown
Main Steam Drains
Auxiliary Steam
Auxiliary Feedwater Pump Steam Supply
Crossover and Crossunder Piping
The following components are included in the E/C program:
Control Valves/Check Valves
Tees and Branches
Expanders and Reducers
Flow Nozzles and Orifices
Exit Nozzles
Elbows and Reducing Elbows
Strai~ht Pipe Sections
Heater Drain Tanks
Reheater Drain Tanks
Pump Casings (heater drain and condensate pumps)
Main condenser (internal sparger, expansion joints)
UT thickness measurement procedures are approved in
accordance with the licensee QA program.
Procedures define
methods for: performing UT measurements, grid spacing
criteria, ensuring that followup inspections are taken at
I
I
10
the same locations as the previous inspections, ensuring the
use of certified inspection personnel, analYzing the results
of UT measurements, and establishing acceptance criteria.
Minimum wall thickness (tmin) requirements for safety-
related and non-safety related piping are based on code
allowable minimum wall thickness.
The licensee's method of analyzing UT data includes:
calculating the wear rate (wr) based on point to point
measurements, .band method, area method, and average method;
predicting the thickness (t) at the next refueling outage
based on tpredicted = tmeasured - wr X current operating eye le
time; determination of current acceptance based on tmeasured >
tminimum and tpredicted > tminimum; and calculation of remaining
life based on remaining life= (tmeasured - tminimum) divided by
the wr.
Repair and replacement of safety-related and balance of
plant eroded components is covered by the licensee's R&R
program meeting ASME Section XI.
Welding and NDE of repairs
and replacements are accomplished by qualified personnel and
suitable procedures for safety-related and balance of plant
piping.

b.
In addition to review of the program, as detailed in the documents
listed above, and discussion of the program with the responsible
engineer,- the inspector reviewed the fo 11 owing outage documents:
Seconda~y Piping and Component Inspection Program dated
October 2, 1992 and updated on March 3, 1993
Design Change Number 92-67-2, MI Secondary Piping
Replacements Surry Unit 2, including Field Changes 1
through 5
The Inspection Program (Outage Plan) included 80 piping components
from l" to 24" in diameter.
In addition the plan included a
number of other* components such as, mairi condenser, crossunder
piping, valves, steam generator "B" feedring, etc. The Design
Change was for replacement of a number of piping runs and
components in the Feedwater, Condensate, Steam Drains, and
Extraction Steam systems because of FAC.~ The piping was being
upgraded to Chromium - Molybdenum (CR-MO) steel.
11
The inspector also observed the following field activities to
verify inspection grid layout and UT wall thickness measurements
were being accomplished in accordance witb procedures:
Results
UT inspection of Component 2-CN-PPS-110 on drawing 11548-
WFPD-12 *
UT inspection and grid layout of components 2-SD-PSF2-284
and 2-SD-PPS-605 on drawing 11548-WFPD-104
Grid layout of components 2-SD-PSF2-299 and 2-SD-PPS-623 on
drawing 11548-WFPD-106
Personnel certification records were reviewed for NOE
examiners performing the above activities.*
The licensee has a very strong, pro-active FAC program with strong
corporate and site support and dedicated resources.
EPRI developed
computerized programs CHECMATE and CHEC-NDE are used for in the
selection of susceptible components and evaluation of inspection
results. Over SOOO_components per unit are included in the program.
FAC degraded piping components are being routinely identifi~d and
replaced with upgraded CR-MO steel.
In the areas inspected, np violations or deviations were identified.
4.
Steam Generator (S/G) Feedwater Nozzle Inspections
See NRC Report 50-280, 281/92-09 for documentation of a previous
inspection of this area.
A number of PWR plants have identified thermal fatigue cracking of
piping at the S/G Feedwater nozzle.
The tracking was attributed to
thermally induced fatigue caused by introducing relatively cold
feedwater into the main feedwater pipe upstream of the S/G.
This
cracking problem was identified in 1979 and NRC Bulletin 79-13 was
issued to require inspection and replacement of defective feedwater
piping components.
B~~ed on the currently identified cracking, the pipi~g components at
North Anna steam generator nozzles were inspected and cracks were found
in loops "A" and "C".
The following actions were performed by the
licensee:
Other utilities were surveyed to determine industry experience.
A history" of inspections and pipe replacement activities, since
issue of NRC Bulletin 79-13, for the affected piping was compiled
for North Anna and Surry.
12
A metallurgical analysis was performed on the cracks found at
North Anna.
Based on the track depth at North Anna, a crack growth rate was
established.
Based on a projected crack growth rate and the previous
replacements of the affected piping at Surry, a scheduled
augmented inspection was developed for Surry and North Anna.
Licensee Report, Thermal Fatigue Cracking of Feedwater Piping North Anna
Power Station- Unit 1, dated February 12, 1993, documents the above
actions.
The inspector reviewed the report and found it to be a very
thorough appraisal of the problem with realistic future inspection
schedules recommended.
In the areas inspected, no violations or deviations were identified.
5.
Safety Related Pipe Welding (55050)
The applicable code for safety-related pipe welding observed is USA
Power Piping Code 831.1.0 - 1967.
The inspector observed in-process
welding and reviewed in-process records as indicated below to determine
whether these activities were being performed in accordance with
applicable codes, standards and regulatory requirements.
The inspector observed fitup, in-process welding, and the final weld
surface for welds 1, 2, 3, 4, 5, 9, 11, 13, 14, and 16 on drawing
DCP-12-E237.
In add.ition, final weld surfaces were observed for non-
safety-related welds 3, 4, 5, 7, 8, and 10 on drawing DCP-67-E210.
For
these welds, the inspector reviewed in-process weld records and examined
weld appearance, weld material control, use of correct weld material,
use of correct welding procedure, and welder qualification and general
knowledge and ability.
In the areas inspected, no violations or deviations were identified.
6.
Licensee Action on Previous Inspection Findings
(Closed) Violation 280/92-09-01, Failure to Follow Procedures and
Instructions for NDE of Piping
This violation involved failure to perform ISI (VT and PT) inspections
of a Recirculation Spray Ring in accordance with Technical Specification
and procedure requirements.
Only 9" bands around the header, in lieu of
100% of the surface, were VT inspected.
In addition, PT testing was
being performed without removing blotches of paint and other foreign
material .
13
The licensee's letter of response, dated June 8, 1992, was reviewed and
found to be acceptable.
The inspector discussed the corrective-actions
with responsible licensee personnel and reviewed documentation of the
following corrective actions:
All examinations on the ring header were re-performed.
The NOE examiner who performed the PT inspections without removal
of foreign materials was re-trained and re-tested.
All. contract NOE personnel were instructed on the importance of
following procedures and were required to re-review the
requirements of the surface examination NOE procedures.
All inspections performed by the individual were reviewed and a
random sample of his inspections were re-performed by licensee
qualifted NOE examiners ~ith no problems being identified.
Records for the Spray Ring VT inspection performed during the last
outage were reviewed and no problems were identified.
In
addition, a licensee NDE examiner recalled observing part of that
inspection and indicated the inspections were performed correctly.
Based on review of the above corrective actions, this item is closed.
