McGuire and Catawba Nuclear Stations issues for Discussion in a Telephone Conference Stated in Duke's submittal stated: "The overall condition of the coatings was satisfactory with only minorlocalized coating deficiencies noted." Describe these areas of minorlocalized coating deficiencies:
Type of deficiencies (i.e., delamination)
Location Approximate size of area affected Have there been any major recoatings in containment? If so, when and approximately how much I area was recoated?

I APPLIED CONTAINMENT COATINGS SURVEY PURPOSE: Identify containment protective coatings which have been applied to steel and concrete substrates at time of plant construction and other coatings applied at a later date resulting from maintenance and/or replacement of coated surfaces.
NEEDED: RES (in support of an NRR User Need Letter) has initiated a coatings research program at W-SRTC (Aiken SC) for the purpe,e of determining coating systems failure mechanisms, estimated time to failure during the post-LOCA period and i identification of the failed coating debris characteristics (e.g. failed material l composition, geometry and size characteristics). This information will be used to identify applie d Class I coatings (see DG-1076, 3/1999, for coating designation definitions) which should be considered for evaluation in SRTC's coatings program.
The failed coating (s) debris characteristics identified will be used for GSI-191 (PWR Sump Blockage) studies to evaluate the potential for transport of such debris to the ECCS sump during the post-LOCA period.
Coatings Related Information::
- Class I coating systems applied to steel and concrete substrates within containment at time of construction and coatings applied during the plant operating life for purpose of coating condition maintenance and/or replacement.
The following coating systems were identified recently by a Phenomena
! Identification and Ranking Table (PIRT) coatings panel (comprised of NPP containment coatings experts) are provided as examples of typical coatings l systems applied in NPPs.
Steel substrate, inorganic Zinc Primer, Epoxy Phenolic Topcoat Steel substrate. epoxy phenolic primer, epoxy phenolic topcoat Steel substrate, inorganic zine primer, epoxy topcoat Steel substrate, epoxy primer, epoxy topcoat Concrete substrate, surfacer, epoxy phenolic topcoat Concrete substrate, surfacer, epoxy topcoat Concrete substrate, epoxy phenolic primer, epoxy phenolic topcoat ,
Concrete substrate, epoxy primer, epoxy topcoat i
Identification of coating material designation (i.e. Carboline 930). Although generic coating types are identified above, identification by trade name or replacement product is desirable.
. Coating materials manufacturer (e.g. Ameron, Carboline, Keeler & Long). This information is needed if specialty formulations will need to be procured.
Attachment 2
F c
l 1
Identification of steel and concrete coated regions and components (eg.
- containment dome, mid level, lower level, sump proximity) by location and approximate area coverage for the major Class I coating systems. Some of this information may a! ready be summarized in UFSARs or the licensee may have onsite studies (or other information) the staff can review as needed.
Reference to such information is an acceptable response.
- 5. Chemicals (or other materials) used for cleaning, or washing down, coated surfaces following reactor refueling and identification of those coatings subjected to such cleaning materials and location Other useful information (if reaoily available)::
- 1. Coating materials physical properties such as: adhesion, ductility, expansion and other mechanical properties.
- 2. Operating and shutdown environmental conditions such as: typical radiation dose l levels and thermal environment.' A range of temperature conditions, dose levels and humidity levels (power operation and refueling periods) would be useful for consideration preparing test samples.. l
- 3. Coating specification, procurement and application requirements and where located or referenced if such information needs to be accessed at a later time..

NEEDED: Plant coating samples which could be made available for testing at SRTC. to gain simulated DBA survivalinsights for comparison with current DBA test coupons which are said to " bound" post-LOCA conditions. Examples: coated steel (i.e. 6 in by 6 in or smaller) which has been removed from containment following snubber relaxation activities, failed coating section which has remained intact)
Schedule: SRTC program is underway and plant survey information needs acquired by end of June 1999 would provide a means to better ensure that a major coating system had been missed. Coatings samples / specimens will be gratefully accepted throughout CY 1999.
