l l
k ATTACHMENT 1 SUPPORT I.D. NUMBER is a unique hanger mark number used to identify each
, support. For example, the support I.D. number 51-02-0326-H005 refers to:
S1 - Support at SONGS-1 02 - Identifies general area of location in plant 032u - Identifies piping line number or which support is located H005 - Designates the hanger number.
DATA POINT is the nodal point used in modeling each support on the piping isometric (mathematical model).
TYPE defines the type and direction of each support such as Y rigid or X 7 snubber.
STATUS refers to construction status. The following statuses are used:
[ CX ,= Completed new support CM = Completed modification CR = Completed repair CN = Completed no change IX = Incomplete new support IM = Incomplete modification IR = Incomplete repair MAXIMUM STRESS RATIO defines the ratio of the capacity of the support to which it is loaded and hence, provides an indication of the margin of safety for each support. The support capacities are evaluated based l on the design requirements as defined in the ASE Code for Level D loads (attached as Table 1). In cases where departure from code allowables are taken for Return to Service conditions, an asterisk notation is povided by the support classification. i
~~
SUPPORT CLASSIFICATION refers to the categorization of the active supports.
This is described below:
Type A: Those supports which will remain below functionality limit through the DBE event.
Type B: Those supports which will' yield but will maintain load carrying capability.
Type C: Those supports which will fail in a brittle manner and will provide no load carrying capability.
ATTACHMENT L
.I Page Two )
For those existing supports which are classified as Types B and C, no stress ratio is provided indicating that these supports have either yielded (Type B) or failed (Type C). However, it is explicitly shown by means of the energy balance method that the yielding or failure of these supports will not impair the functionality of the piping and of the other Type A (qualified) supports. -
NOTES In this column, various notes are provided pertaining to whether the as-installed support is sufficient or further construction work is required. For those supports where construction is required, it is also indicated whether the existing designs are adequate or redesign or modification to existing designs is required.

NOTES:
1- Construction is not required. As-installed support is sufficient.

Q DRAFT 8/16/84 STATUS OF COMPLETION OF JUNE 24, 1982 COMMITMENTS - SAN ONOFRE 1 The June 24, 1982 letter outlined the activities for completion of seismic upgrading of San Onofre 1 to the 0.67g Housner spectra. The status of each aspect of this program is described below.
A. Site Ground Motion By letter dated September 16, 1982, the staff concluded that the 0.679 Housner ground response spectrum with a 10% increase in the 0.07 to 0.25 second period range and the 0.44g Housner ground response spectrum with a 10% increase in the 0.05 to 0.15 secomf period range are the r- appropriate horizontal and vertical free motions for seismic reevaluation.
.\ -
On August 16, 1984, the staff reconfirmed its decision on the vertical 1
ground motion. Therefore, this activity is complete.
B. In-situ Soil Conditions '
The soil conditions have been characterized and the effects on structures, systems and components under seismic loading have been evaluated. Some modificatiors were made, such as to the auxiliary feed-water pump supports and the 480v room foundation as a result. The staff has concluded that the seawall will remain functional following the postulated ea.rthquake. Review of the settlement aspects is still continuing; however, this issue does not need to be resolved for restart.
C. Structures The analysis of safety-related structures has been completed.
Modifications have been made to reactor auxiliary building connections, turbine building bracing and intake structure walls. The staff still C/L3
(
has some questions regarding the fuel storage building, but these questions are not of such significance as to require resolution prior to restart.
The degradation of intake structure rebar will have to be assessed, but this structure is not required to maintain a hot standby condition. The licensee is proceeding to install steel plates on the intake structure
~
walls to enable the structure to withstand a 0.679 earthquake with no credit for the rebar on the inside of the walls.
C.8 Masonry Walls The analysis methodology has been validated by a test program to show that masonry walls will not catastrophically fail as a result of the postulated earthquake. Some modifications were made to connections and
~'
stiffening braces were installed in locations where excessive deflection of the wall might affect attached equipment. A lotter describing the licensee actions relative to dsflection of masonry walls will be provided in September 1984.
C.9 In-situ Response Spectra This issue is resolved per the July 7, 1983 trip report.
D. Mechanical Equipment and Piping Systems and components required to prevent accidents and to reach a hot standby condition have been upgraded. A new auxiliary feedwater
' storage tank and new AFW piping have been installed. The upgrading of supports of remaining systems and components normally used for cold shutdown and for accident mitigating systems have not yet been completed.
~~N . .
, E. Electrical Raceways and Conduits Most of the conduit and cable tray modifications have been completed.
~
Based on the upgrading program being conducted by the licensee and the modifications to date, it is concluded that this equipment will survive the postulated earthquake.
F. Anchorace of Electrical Equipment Licensee evaluation and modification of anchorages of safety-related electrical equipment is complete. Staff review is continuing.
G. Seismic Backfit Project There are no open items on this review (see July 7,1983 letter).
