FPC RESPONSE.T0 IE BULLETIN 80-11 MASONRY WALL DESIGN ITEMS 1, 2a, AND 3 ITEM 1 Identify all masonry. walls in your facility which are in proximity to or have attachments from safety-related piping or equipment such that wall failure could af fect a safety-related system.
Describe the systems and equipment, both safety and non-safety-related, associated with these ma-sonry wa!-Is.
Include in your review, masonry walls that are intended to resist impact or pressurization loads, such as missiles, pipe whip, pipe break, jet inpingement, or tornado, and fi re or water barriers, or shield walls. Equipment to be considered as attachments or in proximity to the walls shall include, but is not limited to, pumps, valves, mo-tors, heat exchangers, cable trays, cable / conduit, HVAC ductwork, cad electrical cabinets,. instrumentation, and controls.
Plant surveys, if necessary, for areas inaccessible during normal plant operation shall be performed at the earliest opportunity.

t ITEM 2 Provide a re-evaluation of the design adequacy of the walls identified
- in. Item 1 above to determine whether the masonry wal?s will perform their intended function under all postulated loads and' load combina-tions.
In this regard, the NRC encourages the formation of an owners'
- group to establish' both appropriate re-evaluation criteria and where necessary, a laten confirmatory masonry test program to quantify the safety margins established by the re-evaluation criteria (this is dis-cussed fruther in Item 3 below).
a.
Establish a prioritized program for the re-evaluation of the masonry walls. Provide a description of the program and a de-tailed schedule for completion of the re-evaluatic ) for the categories in the program.
The completion date of all re-evaluations should not be more than 180 days from the date of this Bulletin. A higher priority should be placed on the wall re-evaluations considering safety-related piping 2-1/2 inches or greater in diameter, piping with support loads due to ther-mal expansion greater than 100 pounds, safety-related equip-merit weighing 100 pounds or greater, the safety significance of the potentially af fected systems, the overall loads on the
~
wall, and the opportunity for performing plant survey ; and, if necessary, modifications in areas otherwise inaccess4 ale.
The factors described above are meant to provide guidance in de-termining what loads may significantly affect the ma onry wall analyses.
' RESPONSE FPC reevaluation program includhs tne following:
1.
FPC, in conjunction with Gilbert Associates, Inc.,
will be performing a field survey of all Safety-related piping and equipments attached to or in the vicinity of the walls identified in Item 1.
2.
Results of item 2a.1 will be reviewed to set priori-ties for reevaluating walls depending upon impact on Safety-related systems and/or equipments.
Masonry walls in the vicinity of these Safety-related piping or equipments will be reevaluated and analyzed on a priority basis to determine loads.
Results of these analyses will be included in the 180-day re-
.sponse to the NRC.
ITEM 3 Existing test data or conservative assumptions may be used to justify the re-evaluation acceptance criteria if the criteria are shown to be.
Lobo (M05 Resp)DN-98-3 t
conservative and applicable for the actual plant conditions.
In the ab-sence of appropriate acceptance criteria a confirmatory masonry wall test program is required by the NRC in order to quantify the safety mar-Gins inherent in the re-evaluation criteria.
Describe in detail the ac-tions planned and their schedule to justify the re-evaluation criteria used in Item 2.-
If a test program is necessary, provide your comitment for such a program and a schedule for submittal of a description of the test program and a schedule for completion of the program.
This test program should address all appropriate loads (seismic, tornado, missile, etc.).
It is expected that the test program will extend beyond the 180-day period allowed for the other Bulletir :etions.
Submit the re-suits of the test program.upon its completion.
Resp 0NSE FPC will develop a reevaluation acceptance criteria for walls based on conservative design assumptions which is consistent with our schedule in Item 2a.
Should a test program te neces-sary, we will notify you immediately and provide our schedules for submittal of a description and completion of the test program.7 Lobo (M05 Resp)DN-98-3 I i
