DEC 8 1986 Docket Nos.: 50-528, 50-529 and 50-530 LICENSEE: Arizona Public Service Company FACILITY: Palo Verde, Units 1, 2 and 3
SUBJECT:
SUMMARY
OF MEETING ON MASONRY WALLS A meeting was held in Bethesda, Maryland on August 28, 1986, with representatives of the licensee. The purpose of the meeting was to discuss the licensee's evaluation of the adequacy ~of certain masonry walls at Palo Verde. The meeting was a follow-up to the August 20, 1986 meeting on the same subject (see Meeting Sunnary, dated October 6,1986). Enclosure 1 lists the meeting attendees and the meeting is summarized as follows:
Summary The licensee's presentation was based on the viewgraphs provided as Enclosure 2.
The licensee stated that, following the August 20, 1986 meeting, it has been performing further research and evaluations to address the staff's concerns regarding the adequacy of the mase ialls at the 74 foot elevation of the Palo Verde Control Building. The .r.cific concerns and the licensee's additional efforts are identified in Enclosure 2.
The licensee indicated that it plans to submit additional information for staff review after the licensee completes its additional evaluations. The staff stated that it would review any material submitted by the licensee. The staff indicated, however, that based on its preliminary understanding of the cdditional efforts being undertaken, it did not expect that its concerns would be resolved solely by analysis of the as-built condition of the 74 foot elevation masonry walls.

- MULTIPLE SAFETY RELATED COMPONENTS PENETRATING AND ATTACHED TO WALL, OR IN IMMEDIATE VICINITY.
- HOWEVER MINIMAL SAFE SHUTDOWN RELATED COMP 0NENTS SUPPORTED FROM DIRECTLY OFF WALL OR PENETRATING WALL.
- STRINGENT WORKING CONDITIONS REQUIRED TO MINIMIZE (
THE RISK OF DAMAGE TO SAFETY RELATED COMPONENTS.
- CONSTRUCTION RISK IS ORDERS OF MAGNITUDE HIGHER THAN THE RISK ASSOCIATED WITH SSE.

, AND PVNGS MASONRY WALLS TEST (1) PVNGS REMARKS GROUT STRENGTH 3060 PSI 2600+ PSI DIFFERENCE IN GROUT STRENGTH DOES NOT SIGNIFICANTLY AFFECT b (TEST DATA).
MORTAR STRENGTH 2520 PSI 2200- PVNGS VALUES ARE SIMILAR TO 2800 PSI TEST DATA.
MASONRY STRENGTH 3640 PSI 2000 PSI DIFFERENCE IN MASONRY STRENGTH DOES NOT AFFECT fe.SINCE FAILURE OCCURS AT BED JOINTS.
REINFORCEMENT NONE REINFORCED bnnISINDEPENDENTOF REINFORCEMENT.
BLOCK SIZE 8"x8"x16" 4"x 12"x 16" LOWER HEIGHT OF PVNGS UNITS REDUCES STRESS CONCENTRATIONS.
