ASME Boiler and Pressure Vessel Code (Code) with respect to ASME Section XI.
In no case does this restrict NP employees from providing either verbal or written Code interpretations which are not included in this Site Standard Practice.
.2.0 INTERPRETATIONS 2.1 Scope of the Code The scope of the Code includes those safety-related systems where the contained fluid is water, steam, or radioactive waste. Other systems that are safety related should be tested to quality standards commensurate with the system safety function, but at the present time these systems are not included in the scope of the Code. Some systems not in the scope of the Code are included in the Code pump and valve testing program as directed by NRC.
Regulatory Guide 1.26 presents guidance on system quality group classifications.
The majority of TVA's system classifications for inservice inspection are based on this regulatory guide. At the present time the regulatory guide does not specifically j
address radioactive waste management systems.

Component (s): Rod Control Cluster Assembly (RCCA) Cladding Wear Measurements.
NOTE:
The RCCA rodlet cladding wear for both SON units has been examined via. the eddy current measurement NDE technique. Encircling coils were used for total area loss determinations and profilometry data taken to characterize wear scars. SON Unit 2 RCCAs were inspected in April 1990. Results were documented (L38 890511800 and L36 901030 800). Summaries were provided in the ISI Reports.
Because TVA has cladding wear data for each unit's RCCAs and has implemented an axially repositioning program, RCCA inspections need only to be done periodically in the future when identified by PWR Fuel Engineering. When performed, the results will be reviewed, the wear data bases updated, and specific repositioning plans revised as necessary.
Any RCCA with excessive rodlet cladding wear will be replaced.
RCCA wear examinations via NDE techniques are self-imposed by TVA and do not require a special report. An examination summary shall be included in the Site Final Report discussed in this SSP whenever the RCCAs are inspected for either SON Unit 1 or 2.

' General I
A.
The following methodology shall be used to determine the component support examination boundary.
1.
Supports depicted as snubbers on the support drawings are subject to examination outside the boundaries of the snubber (beyond the pins) in j
accordance with IWF-5300(c). The pin to pin exa;nination of snubbers are covered by SSP-8,54.
2.
In all cases involving attachments weMed to pressure retaining components and/or supports welded to building structure / existing steel, the weld shall be included within the examination boundary.
3.
If component supports are machan'cally attached to an embedded plate, i
the mechanical attachment is inciuded within the Code boundary.

COMPONENT SUPPORT EXAMINATION Rsv 0 BOUNDARIES Page 4 of 9 6.1.1 General (Continued) 4.
Concrete bolt anchors, anchors, are not included within the Section XI code boundary and, therefore, do not fall within the examination boundary.
Even though anchors may be listed on a support bill of materials, they are not required to be examined. (This note pertains to anchors only, not the associated botting.)
I 5.
The anchor bolting used to attach surface-mounted baseplates to building structure is not included within the Code boundary. However, this anchor bolting will receive a visual examination in accordance with the ASME r
Section XI ISI/NDE Program, but is exempt from the Repair / Replacement Program, SSP-6.9.
i 6.
All shims and lugs adjacent to the supported pipe shall be examined.
Even though the shims and lugs may not be listed on the support bill of F
materials, they are required to be examined.
7.
Notification of Indication (NOI) form in Attachment 4 shall be used to report l
unacceptable indications on component supports only if the criteria in a, b, l
and c, below, are met:
The component support falls within the scope of ASME Section XI.
a.
i b.
The component support is part of the inservice inspection examination
- sample, h
c.
The indication falls within the component support's examination j
boundary as set forth by this Instruction Indications that do not meet the criteria in a, b, and c, above, should l
be noted by other means, such as, MR's, WR's, etc.
B.
For each component support to be reviewed for examination boundary determination, obtain the latest configuration controlled drawing (CCD) of the support. If a CCD does not exist, obtain the latest as-constructed drawing of the support. If an as-constructed drawing does not exist, obtain the latest as-designed drawing of the support. For new or modified supports, the drawing included in the work instruction may be utilized. Using the drawing, classify the support in one of the following categories:
1.
Support is shown as being attached to building floor, wall, ceiling or embedded plate.
I 2.
Support is shown as being attached to " existing support."
3.
Support is shown as being attached to " existing steel."

6.1.1 General (Continued) 4.
Support is shown as being attached to an intervening element.
After classifying the support in one of the categories, proceed to the corresponding section to complete the boundary determination.
C.
As each support is categorized, the category identifier, shall be input with the respective support in the PRISIM data base.
D.
As supports are added or revised in the PRISIM data base, this Instruction shall be used to determine or revise the examination boundary for that support.
6.1.2 Supports Attached to Building Floor, Wall, Colling, or Embedded Plate For supports attached to building floor, wall, ceiling or embedded plates, the boundary shall be defined as the point (s)/ area (s) of contact between the support and the building structure, along the support load path (s), up to, but not including the pressure retaining component. In addition to the requirements of 6.1.1.A, each item in the support bill of materials, except concrete anchors and material used as a spacer to allow for grouting between the base plate and the builc'ing floor, wall, or ceiling, is to be included within the boundary.
l This category of supports shall be considered Examination Boundary A and so designated in the PRISIM data base.
6.1.3 Supports Attached to Existing Supports NOTE For clarity, Support A is the support being reviewed for boundary determination and Support B is the " existing support" to which Support Ais attached.
The boundary of Support A shall be defined as the point (s)/ area (s) of contact between Support A and Support B, along the support load path (s), up to, but not including, the pressure retaining component. In addition to the requirements of 6.1.1.A each item in Support A bill of materials is to be included within the boundary.
In the case of multiple supports (i.e. 3 or more supports) the boundary shall be determined in the same manner as above.
~. _
SQN CUIDELINES FOR DETERMINING PIPIN3 SSP-6.10 Att. 3 COMPONENT SUPPORT EXAMINATION R;v 0 BOUNDARIES Page 6 of 9 This category of supports shall be considered Examination Boundary B and so designated in the PRISIM data base. In the PRISIM data base, Support B will be identified as the support to which Support A is attached. (" Examine to Support B.")
6.1.4 Supports Attached to Existing Steel For supports attached to existing steel, the boundary (including the attachment weld) shall be defined as the point (s)/ area (s) of contact between the support and
" existing steel," along the support load path (s), up to, but not including the pressure retaining component. In addition to the requirements of 6.1.1.A, all items listed on the support bill of materials are to be included within the boundary. For WA designed supports, the examination boundary may be determined from TVA drawings.
This category of supports shall be considered Examination Boundary C and so designated in the PRISIM data base.
6.1.5 Supports Attached to Intervening Element For supports attached to an intervening element, the boundary shall be defined as the attachment portion of the intervening element (i.e., welds, bolting, pins, clamps, etc.) to the pressure retaining component and all support members up to, but not including, the intervening element. In addition to the requirements of 6.1.1.A, all items listed in the support bill of materials are to be included within the boundary.
This category of supports shall be considered Examination Boundary D and so designated in the PRISIM data base.
6.1.6 Supports Attached to Various Structures in many cases, one component support is attached to more than one type of structure. These supports will have more than one Examination Boundary Designator in the PRISIM data base. In all cases, however, the examination boundary for each component support shall include:
A.
All items listed on the support's bill of materials, except concrete anchors. For TVA designed supports, the examination boundary may be determined from TVA drawings.
B.
All shims and lugs adjacent to the supported pipe.
SQN CUIDELINES FOR DETERMININS PIPING SSP-6.10 Att. 3 COMPONENT SUPPORT EXAMINATION R::v 0 BOUNDARIES Page 7 of 9 6.2 Site implementation A.
Obtain the latest CCD of the support. If a CCD does not exist, the latest as-constructed drawing shall be obtained. If an as-constructed drawing does not exist, the latest as-designed drawing shall be obtained. If during the performance of an examination, significant differences are identified between the support drawing and the support field configuration, access the Design Change Document Tracking System (DCDTS) to identify any outstanding change documents on that component support.
J For each component support that does have an outstanding change documented listed on the DCDTS, ISI/NDE Representative shall determine through the work package project engineer if the work has been completed on that particular support. If the work has been completed, ISI/NDE Representative shall obtain the change document support drawing. If the work has not been completed, the examination shall be delayed until the work has been completed.
1 NOTE As an alternative to obtaining the latest as configured drawings and the bill of materials, the component support examination boundary may be defined as the attachment to the component, up to and including the attachment to the floor, wall, and ceiling.
B.
For variable support settings use the drawing obtained per A. above to verify that the thermal movement and support type given on the support drawing matches the corresponding information given in the Scan Plan or implementing instruction (WR/WO, WP, etc.). If the movement and support type do not match:
l 1.
The setting shall be calculated in accordance with Inspection Services Organization Program Manual (Refer to IEP series).
2.
Submit a Component Support Examination Boundary Clarification Request Form to. Upon receipt of a request, an ISI/NDE Representative shall review the discrepancy and make any necessary changes to the i
examination boundary. If a request has been submitted (when verbal instructions were not requested), the request will be completed and returned to the person requesting the examination boundary clarification.
A support shall not be examined until any discrepancies on that support are eliminated. Any changes in the Examination Boundary shall be i
incorporated in the PRISIM data base, NOTE See Section 7.0 for example boundaries of each examination boundary.
