Title:
PAINTING REQUIRENENTS RELATED TO WELDS I
I.
SCOPE OF EVALUATION L
This engineering analysis covers the following WBN concerns determined to have possible generic implications at SQN:
IN-85-273-001 i
IN-85-192-002 EI-85-059-001 IN-85-451-001 II.
ISSUES ADDRESSED BY CONCERN (S)
Each concern was analyzed to determine the issues voiced by the concerned individuals. These issues are as follows:
1.
Welds over six feet off the floor have not been painted in the Reactor and Auxiliary buildings.
l 2.
Unpainted welds are in evidence on conduit and piping supports in L
the Reactor Building.
Ib 3.
Hanger welds should be painted as soon as they are finalized by QC.
4.
Rust causes welds to be weakened.
5.
Sandblasting removes metal from welds.
i III. CONCERN VALIDITY OR SUBSTANTIATION The prime consideration for application of protective coatings in l
nuclear facilities is one of effective prevention of build-up of l
radioactive contamination on the building, structures, components.
l and systems of the facility. A secondary consideration is to provide lR1 a smooth, impervious surface (via a paint system) which will permit l
subsequent decontamination activities. These two considerations are l
effectively met by using nuclear grade coating systems.
Using these l
basic considerations and additional environmental conditions, l
protective coating requirements are established by the Office of Engineering (OE) for every feature in the powerhouse. These requirements are transmitted to the Office of Construction (OC) or Nuclear Operations (NO) via drawings and specifications. The implementing organisations (OC or NO) cost the features based upon environmental conditions which that particular area will experience in plant operations. Not all areas are required to be coated.

WP-08-SQN, R1 P!-
The general nature and large scope of issues 1 and 2 prevents a l
direct physical inspection of the Reactor and Auxiliary Buildings by l
Welding Project Ivaluators. A correspondence search and discussions l
with the Division of Nuclear Quality Assurance revealed that a comprehensive l l
reinspection of protective coatings has been initiated as the result l
of a QA survey.
The results of this survey are documented on lR1 SQN-CAR-86-01-001. An integral part of this reinspection program l
will include a 100 percent baseline coating inspection of the Level 1 l
and 2 coating areas at SQN. SQN-CAR-86-01-001 describes the details l
of the deficiencies in the Protective Coating Program. Coating l
deficiencies are being identified and appropriate corrective actions l
are being established which address both program deficiencies and l
repairs to coated features.
l There are no requirements which mandate a particular sequence of construction or modifications activities. The schedule is determined using prudent engineering judgement. OC or NO accomplishes coating operations based on a schedule intended to maximize efficiency in construction or modification activities.
All metallic materials oxidize (rust) to varying degrees. The engineering analysis of the need for coatings takes this characteristic into account. When a surface requires coating, the rust is removed.
l Removal is primarily by sandblasting which has been and continues to be p*~
an industry-wide acceptable method of preparation of metallic features l
for painting. The metal removed in this process is minimal.
In summary, the resolution of each issue is as follows:
Issues 1, 2, and 4 are closed pending completion of protective coating reinspection and resultant co.rrective action under SQN-CAR-86-01-001.
Issue 3 is closed because it is an observation of prudent construction practices.
Issue 5 is closed because the practice of sandblasting is an accepted practice in preparation of metals for painting.

The responsibility for these deficiencies involves various groups and organizations. Since these deficiencies all relate to the site Protec-2 tive Coating Program, it was determined that resulting corrective actioK~
~
would be more effective if tracked and handled under one corrective action report.
2.
Presently, there are m Nuclear Power upper tier documents describing a Protective Coating Program. The references to G-Specifications and Architectural Design Standards within this CAR are applicable because the notes on "As-Constructed" Drawing 46W466-1 refer to Construction Specifications G-41, G-42, and G-45 which were canceled. The index for -
Construction Specifications states that G-41, G-42, and G-45 were replaced by G-55.
C-55 refers to G-14 for selecting, specifying, applying, and inspecting architectural paints and coatings. G-14 refers to Endes Architectural Design Guide DG-A9.8.1 regarding Nuclear Service Level I applications.

Contrary to the 'FSAR Section 6.2.1.6 no program.has been established
..,0 or implemented at Sequoyah to account for unident'ified/ uncontrolled coatings which have been applied to components installed in Level I coating areas.
(e.g., Coatings on vendor supplied equipment such as motors -
or junction boxes. Specifically, some instrument panel mounting plates -- -
to be installed in a Level I coating, area were coated using unapproved coatings (on MR A-564799) as specified on TVA drawing 46W600-23 without consideration for their impact on the percentage of unapproved coatings within containment.)
a.
MI-10.14 does not require the use of specific types of protective coatings for application on certain equipment as delineated in Section 6.2.1.6 of the FSAR.
(e.g., RCP motors, accumulators, stesa generators, etc.)
S O
. Corrective action must include:
(1) an evaluation (USQD, NCR,.
NOTE:
etc.) of any installation of unidentified coatings which asy not i,'
have been accounted for and (2) correction of drawings (i.e.,
a 46W600-23) which specifies use of an unapproved coating on
" ".i.
equipment to be installed in a Level I coating a'rea.
~;,
2.
MI-10.14 does not adequately implement the requirements of G-55, G-14, FSAR Section 6.2, and Architectural Design Standard DS-A.9.8.1.
Examples:
l v
a.
No definitions are contained in MI-10.14 to identify Level I and (f6 Level II coating areas as specified in Architectural Design Standard DS-4.9.8.1.
Additionally, MI-10.14 does not list those Level I coating surfaces which are located outside containment.
(For example, reactor coulant makeup water tank, essential air system tank interiors, emergency diesel fuel storage tank interiors, con-densate storage tanks', and chemical and volume control system /RCS makeup system tank interiors).
5 b.
Periodic surveillance' inspections of Level II coating system main-tenance are not specified in MI-10.14 or performed as required per Section 8.1.1 of G-55.
c.
MI-10.14 does not ensure that coatings which have been stored at 0
low temperatures are brought up to 70 F minimum before application as required in Section 4.3 of G-55.
d.
MI-10.14 does not implement the requirements for adhesion testing that are specified in Section 5.4 of G-55.
MI-10.14 does not require the use of the "Tooke" gauge for verifying i.
e.
adequate dry film thickness for substrates, which are not carbon steel as required pe'r Section 4.5 of G-55.
q NOTE:
Carbon ~ steel substrates are checked using a magnetic gauge.

HI-10.14 references Construction Specifications G-41, G-42, and
(
.G-45 which have been canceled. Additionally, the SQN Protective Coatings Maintenance and Repair Manual is referenced in MI-10.14 1
but has not been approved (by PORC, etc.).
3.
Notes on Drawing 46W466-1 hav,e not been kept current to incorporate changes to Construction Specifications.
(For example, drawing notes contain references to G-41, G-42, and G-45 which have been canceled.
Attachment Cs to AI-25 were submitted during the performance of Survey 21-85-s-015 to correct this specific problem.)
Corrective actions should address not only those actions taken to correct these specific deficiencies, but also actions taken to further identify and correct other deficiencies within the Protective Coatings Program.

costlag areas et SQN. This inspectica will lattiste repolta of areas erith degraded costlag by means of the costlags preventative malatenance program.
N It is my position that our laspection and malatensace program is sofficleat to address the concerns and recommendations of this generic costera.

WP-08-SQN, 31 Attechnext 6 Pego 1 cf 2 CORRRCTIVE ACTION PLAN j
1.
Problem Description No program has been established or implemented at Sequoyah Nuclear Plant (SQN) to account for unidentified / uncontrolled coating which have been applied to components installed in level I coating areas.
Also coating has not been applied to some components within the level 1 areas as required.
Corrective action report number SQ-CAR-86-01-001 has been initiated to correct the deficiencies noted. Corrective action will be tracked on CATD number WP-08-SQN-001.
2.
Corrective Action Plan A comprehensive protective coatings preventative maintenance program was established at SQN. An integral part of the program is to j
perform a 100 percent baseline coating inspection of the levels 1 and 2 coating areas. This inspection will initiate repairs of areas with degraded coatings.
A new SQN is being prepared to provide control of all procedures, methods, responsibilities and documentation of all aspects of l
surface, coating application and maintenance of all critically coated areas at SQN. This-upper-tier document will incorporate the l
requirements of all applicable specifications, design guides and standards, and as-constructed drawings and will establish procedure l
for documenting compliance with the FSAR.
In addition to the implementation of the new SQN, which will provide overall program control for nuclear protective coatings, other existing maintenance instruction procedures will be revised as required to comply with and support the new SQN. New procedures will be issued as required to provide mandatory periodic surveillance inspections of all critically coated areas and to control a documentation log of all uncontrolled coatings inside primary containment.

Action to Prevent Recurrence The'implementatio of the program described above should correct all deficiencies noted by the CAR and should provide complete control and consistent program guidance to correct other deficiencies that may exist and prevent reoccurrence of problems of this nature.

Rusting conditions were found on the following Preventative Maintenance (PN) packages: RN-1474-364, PN-1434-364, PN-1435-364, PN-1439-364, PN-1438-364 PM-1519-364, PN-1520-364, PN-1521-364, PN-1436-364, PN-1437-364, PN-1473-364, and PN-1518-364. These PN packages are being evaluated by ONE. All rusting conditions have been given a repair priority of 2.
Priority 2 items are not required for rastart. NR's and WR's will be generated on these items after ONE completes their review. The implementation of the PN program will ensure that all aress of the containment will be inspected on a periodic basis. This will improve the basic condition of coatings inside the containment building, including welds.

Note of clarification on why WTG did not treat the concerns in WP-19 as being generic to Sequoyah.
The Weld Project took issue with the ECTG's methodology and/or process of making concerns generic to Sequoyah and opted to perform it's own independent evaluation.
The weld project's evaluation consisted of a detail analysis of the concerns and their associated NSRS/ERT investigation reports.
In addition the weld project used some of TVA's senior level welding engineers to determine if the specific issues in question had any generic relevance to Sequoyah.
The result of the weld project review is included in subject report which primarily identifies the concerns and the method used by senior level welding engineers to evaluate the concerns.
Although the weld project did not document the logic used in evaluating each concern the accuracy of the evaluation is supported by the findings and conclusions contained in the other Weld Project Reports.
It is the opinion of the Weld Project that the differences in the evaluation of the concern is related to'the use of the additional information found in the reports as opposed to only using the text of the concern. The evaluation of the concern on the report level under the ECTG Program will resolve any remaining differences between ECTG and WTG on what should be considered generic to Sequoyah.
