Docket No. 50-348 Mr. James P. O'Reilly U. S. Nuclear Regulatory Commission Region II 101 Marietta Street N. W.
Suite 3100 Atlanta, Georgia 30303
Dear Mr. O'Reilly:
In response to I.E. Bulletin No. 80-11, " Masonry Wall Design,"
i dated May 8, 1980, Alabama Power Company submits the following sixty (60) day response for Farley Huclear Plant Unit 1.
Item 1 Identify all masonry valls in your facility which are in proximity to or have attachments from safety-related piping or equipment such that vall failure could affect a safety-related sys,em.
De-scribe the systems and equipment, both safety and non-r2fety-l related, associated with these masonry valls.
Include in your review, masonry valls that are intended to resist impact or pressurization loads, such as missf.les, pipe whip, pipe break, i
jet impingement, or-tornado, and fire or water barriers, or shield valls.
Equipment to be considered as attachments or in proximity to the valls shall include, but is not limited to, pumps, valves, motors, heat exchangers, cable trays, cable / conduit, HVAC ductwork, and electrical cabinets, instrumentation and controls.
Plant surveys, if necessary, for areas 11 accessible during norma.i.
- p. nt operation shall be perfor~.ed at the earliest opportunity.
Response
4 A field walkdown was performed to identify all masonry valls in Farley Nuclear Plant Unit 1, which are in proximity to or have attachments from safety-related piping or equipment. All masonry valis,'the function of each wall, and its relation to safety-related equipment are listed and identified in the attached walk-down summary sheets (Sheets 1 thru 6).
In addition, the walkdown collected data and information for the
. re-evaluation of the design adequacy of the masonry walls. A composite sketch showing the system supports, both safety and non-safety reloted, associated with each masonry vall vill be
,-8 0 0 7 2 9o devel r-d to rerlect the as-duilt condition and incorporatea in I..

Mr. James. P. O'Reilly July 7, 1980 Item 2 Provide a re-evaluation of the design adequacy of the valls identified in Item 1 above to determine whether the masonry walls will perform their intended function under all postulated loads and load combinations.
In this regard, the NRC encourages the
?crmation of an owners' group to establish both appropriate re-evalulatinn criteria and where necessary, a later confirmatory masonry test program to quantify the safety margins established by the re-evaluation criteria (this is discussed further 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 detailed schedule for completion of the re-evaluation for the categories in the program.
The completion date of all re-evaluations should not be more than 180 days from the date of 'his Bulletin. A higher priority should be placed on the vall re-evaluations considering safety-related piping 2-1/2 inches or greater in diameter, piping with support loads due to thermal expansion greater than 100 pounds, safety-related equipment weighing 100 pounds or greater, the safety signif-icance of the potentially affected systems, the overall loads on the vall, and the opportunity for performing plant surveys and, if necessary, modifications in areas otherwise inaccess-ible.
The factors described above are meant to provide guidance in determining what loads may significantly affect the masonry vill analyses.
Resnonce All masonry walls will be re-evaluated using the cc=posite sketch (as-built condition) generated from the field walkdown to ensure the vall vill satisfy the intended function of vall as noted in the walkdown summary sheets.
Faced on the magnitude and number of support loads, all valls are divided into three groups - Priority 1, Priority 2 and Priority 3.
The completion date of re-evaluation for each group is as follows:
Priority 1 To be completed by September 30, 1980 Priority 2 To be completed by October 15, 1980 Priority 3 To be completed by November 7,1980 NOTE:
The valls identified in the attached sheets are grouped by priority.

_ Item 3 Existing test data or conservative assumptions may be used'to 4
1; justify the re-evaluation acceptance criteria if the criteria are shown to-be conservative and applicable for the actual plant
-conditions. In-the absence of appropriate acceptance criteria a confirmatory masonry vall test program is required by the NRC in order to quantir;,* the safety margins inherent in the re-evaluation criteria. Describe in detail the actions planned and their schedule to just;fy the re-evaluation criteria used in Item 2.
If a test prog cam is necessary, provide your commitment 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 vill extend beyond the 180 day period allowed for the other j
Bulletin actions. Submit the results of the test program upon j
its completion.
l Response.
l Justification for the re-evaluation criteria vill be submitted with the re-evaluation report within 180 days of the date of
-l receipt of the Bulletin. Justification vill be based on refer-ence to effective codes and established standards of practice related to concrete and masonry design typically used throughout
{
the industry.
i It~is hnticipated that such justification vill be considered appropriate, and that a test program vill not be necessary.
The one possible exception is masonry wall structural properties for which. construction test data is not available or cannot otherwise be determined.
The other information requested in I.E.Bulletin 80-11 vill be submitted as directed in our 180 day response.
.If there are any questions', please advi:,e.
Yours very truly, F.
. Clayton,gJr.
