I 2 ^; Concrete bolt anchors, such as " red-head" or "rawl" anchors, are not included within the b 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 bolting.)
- 3) . 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 materials, they are required to be examined.
- 4) For component supports that do not have a bill '
l
~]!
s of materials, items to be examined shall be described in the PRISIM data base with the specific ISI support number. i. vA 4mM4 (NP191) ' 1403C/COC3

- 5) Notification of Indication (NOI) forms shall be used to report unacceptable indications on component supports only if the criteria in A, B, and C, below, are met.-
A) the component support falls within the scope of ASME Section XI. B) the component support is part of the inservice inspection examination sample. C) the indication falls within the component-support's examination boundary as set forth ps by this instruction. Indications that do not meet the criteria in A, { B, and C, above, should be noted by other means, such as, MR's, WR's, etc.
; 6) This instruction is intended to deal with piping supports only. Therefore, equipment support drawings will be provided in the ISI Program that depict the examination boundtcv l- for each equipment support.
6.1.1.2 For each component support to be reviewed for
., examination boundary determination, obtain the 4
( 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 v :-7 orts, the drawing included in the work instruction may be utilized. Using the drawing, classify the support in one of the following categories j 1. Support is shown as being attached to building floor, wall, ceiling or embedded plate.
- 2. Support is shown as being attached to " existing support."
- 3. Support is shown as being attached to " existing steel."
q 4. Support is shown as being attached to an intervening element. J Af ter classifying the support in one of the
.! categories, proceed to the corresponding section 2 to complete the boundary determination.

6.1.1.4 As supports are added or revised in the PRISIM data base, this instruction shall be used to determine or i revise the examination boundary for that support. 6.1.2 Supports Attached to Buildino rioor. Wall Cellina, or Embedded Plate For sup, orts attached to building floor, wall, ceiling or embedded plates, the boundary shall be defined as the 'g point (s)/ area (s) of contact between the support and the building structure, along the support load path (s), up to, but _, Including the pressure retaining component. In audition to the requirements of 6.1.1.1, each itwai in the support bill of materials, except concrett anchors, is to be included within the boundary. This category of supports shall be considered Examination Boundary Type A and so designated in the PRISIM data base. 6.1.3 Supports Attached to Existina Supports NOTE: For clarity, Support A la the support being reviewed t for boundary determination and Support B is the { " existing support" to which Support A is 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 l o support load path (s), up to, but not including, the pressure retainitg component. In addition to the requirements of 6.1.1.1, each item in Support A bill of materials is to be included witnin the boundary. This category of supports shall be considered Examination Boundary Type 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 Existina Steel e . F,r supports attached to existing steel, the boundary shall in defined as the point (s)/ area (s) of contact between the p support and " existing steel", along the support load path (s), p up to, but not including the pressure retaining component. In addition to the requirements of 6.1.1.1, all items listed on the support bill of materials are to be included within the boundary. L_

. Functions Circulates reactor coolant Inspection Recuirements ASME Section XI, Table INB-2500-1, examination category B-L-2, item No. B12.20, visual examination of pump internal pressure boundary surface. - Basis for Relieft In absence of required maintenance, disassembly of a M
reactor coolant pump solely to perform a visual examination of internal surfaces is impractical. This vould represent an unnecessary employee erposure to high radiation and contamination areas and an excessive expense to TVA. Time required for this major task of disassembly,
~
examination, and reassembly would consume at least three weeks of 24-hours-per-day work. Radiation dose rates of the pump exterior will average 100 to 300 mrem / hour, and pump internal dose tates will average 10 to 20 rem / hour. The benefit received from this major effort is k minimal considering employee exposure, potential damage to safety-related equipment, and cost in dollars. In addition, the two units at Sequoyah Nuclear Plant will operate under similar conditions. Therefore,
; we feel that if a pump from one of the units is .! disassembled for maintenance during a ten-year interval, the visual examination performed will be representative of the pump condition for each unit.
This would avoid unnecessary employee exposure to the high radiation dose rates noted above. We conclude that if one pump is disassembled for
.! maintenance during the 10-year interval, the visual
,i examination performed satisfies examination category B-L-2 requirements for both units. Disassembly of the pump solely for visual examination is a impractical.

B3.140, volumetric exardnation of nozzle inside radius section on the primary side. Basis for Relief Each steam generator consists of two integrally cast nozzles and two integrally cast manways. Relief from
; the inspection requiremeat above is based on EPRI f! report NP-4242, "Long-Term Inspection Requirements for Nuclear Power Plants", dated March 1986. This
, report presents a linear fracture mechanics analysis which predicts that cracks of size .025 inch (which is greater than the allowable reference flow size) will propagate to only slightly greater than one sixteenth of the noszle wall thickness during the
~ ' '
entire life of the plant. The report proposes that the nozzle inner radius be examined at least at half
, the plant life, and subsequently, at the regular code j inspection intervals.
The primary chamber radistion exposure dose rate is generally on the order of 30 rem /hr. As a result, individual " stay-time in the chamber would be limited to a degree where meaningful results from alternative surface and visua; examinations could not be achieved. In addition, the presence of the interior surface austenitic stainless-steel cladding which has a higher ductility than the base ASME-SA-216 grade WCC casting material raises the possibility of under cladding cracking which would not be visible with a surface examination. Alternate Inspection: TVA will initiate examination of the steam generator nozzle inner radius sections in accordance with the e applicable Section XI Code during the second inspection interval. This will provide for examinat.on of all the steam generator nozzle inner j- , , radii by the period ending at half the plant life. M' a

Basis for Relief: Paragraph T-533.2(a) of Article 5 of ASME Gection V g4 requ.res that the basic calibration block include a basic calibration hole drilled parallel to the contact surface. However, paragraph T-533.2(b) permits the use of other calibration reflectors provided equivalent responses to that from the basic . calibration hole are demonstrated. TVA currently uses 5% notches in lieu of side drilled holes. Although the use of the 5% notch cannot be 1 shown to be equivalent in all cases to the applicable side-drilled holes, TVA considers that examinations are technically acceptable based on the calibration requirements of paragraph III-3430 of Appendix III to j the 1977 Edition, Summery 1978 Addenda of ASME

, ,. 5(
Basis for Religi:1 The res.ctor vessel flangt-to-upper shell weld is , located-behind the core berrel and is therefore i p inaccessible until the core barrel is removed. The , ; '#. vessel flange-to-upper shell weld is 41.9 inches below the flange face. Due to the location of - the
, vessel flange-to-upper shell weld, TVA intends to e address the weld as a reactor vessel shell weld.
We have reviewed the Sequoyah Reactor Vessel Stress Esport entitled Analysis of-the Main Closure Including Core Support Ledge (Document
^[ No. 30616-1105) purposely to determine a fatigue
, I, usage _ factor for the vessel' flange to shell weld.
This analysis does not provide a usage factor specifically for the weld because the analysis considers veld and base material to be homogeneous and equal !.n elasticity, strength,-and fatigue [] . properties. Instead, the analysis provides usage factors at critical locations. f3~ The maximum fatigue usage factor in the vessel in the vacinity of the flange to shell weld as found in'the
- above analysis is 0.00662 and this value can be
-j conservatively used for the weld. We consider the
, i valve of 0.00052 to be extremely low compared to the code allowed fatigue usage factor of 1.0. n.
' We conclude that the distance (41.9") from the flange face to the flange-to-upper shell weld coupled with present ultrasonic techniques and the very low fatigue usage factor that the flange-to-upper shell weld s'aould be treated as a reactor vessel shell weld.
~Afternake Insocction: A remoto ultrasonic examination of the weld will be j] conducted from the vessel inside diameter near the end of the inspection interval.

C1.10, C1.20, and C1.30, volumetric examination of essentially 100 percent of each circumferential weld at gross structural discuntinuities (head-to-shell and tubesh,et-to shell weld) and categories C-C and C-E, Item No. C 3.10, surface examination and visual examinae'sn of integrally welded support attachmente. Basis for Rtiief: The excess letdown heat exchanger (ELHX) and the ragenerative heat exchanger (REX) were scheduled for examination during the first inspection period in il accordance with the In-service Inspection (ISI) Programs SI-114.1 and SI-114.2. The ELEX
~ circumferential head weld was scheduled for ultrasonic (UT) examination in the first three-year inspection period. For the RHX there are six circumferential tubesheet-to-shell welds. Of these, two each of the circumferential head welds and tube
sheet-to-shell welds were to be examined in the first period by UT 1978 Addenda, Table IWC-2500-1 t, Examination Category C-A requires a volumetric examination of 100 percent of the required welds.
i' j The ELEX weld was examined ultrasonically from one side for almost the entire length, except where the head's flanged nozzle-inlet and outlet welds
]) interfered with the examination (see attached drawing). This allowed for an DT examination of 90 percent of the weld from the one side. From the opposite side, the head taper and head closure studs
_ and nuts severely restricted access to the weld area and as a result no meaningful results could be

- capabilities did not allow the achievement of p
I meaningful results because of the component fabrication processes involved. The RHX is a centrifugally cast stainless steel, SA-351, CF8 vessel. In addition, the examinations were hindered by supports which were essentially nonremovable from the area of two of the four welds
. "' ht because of the location in the heat exchanger room ,
and-their position on'the vessel (see attached drawings). As a result, a PT was performed 'in place of the required UT. On the two restricted welds examined, only 75 percent of the weld lengths were surf ace examined because of supports coverir,g part of the weld areas.
' t" Ir accordance with 10 CFR 50.2(v) of the Code of Federal Regulations, the REX and the ELHX are defined
" d. to be within the reactor coolant pressure boundary (RCF3) (ASME Class 1)- Secondly, 10 CFR 50.55.2(c)

Additional system design considerations are tha following: 3;f -1. The ELHX is not used during normal plant I operations and is isolated from the RCS by three valves, two normally closed gate valves and a check valve. i 2. The RHX is isolated from the RCS by two check '
- valves. - Leakage from the RCS is prevented by the
[ two check valves in series which were leak-tested ,q- during the preoperational test program. Leakage - also can be detected by monitoring for signs of , system incoming leakage and by monitoring the RCS i
- f. for signs of outgoing leakage (FSAR 6.3-26).
. [- -I
- 3. .There are no leakage problems into the CVCS from
, h. {/.

the RCS because of the higher pressure at which. the CVCS is generally maintained (FSAR'6.'3-27). p; In addition, the inlot and outlet piping (one inlet i t-a and one outlet) associated with the ELHX is 1-inch 7 nominal pipe size (NPS) and 3-inch NPS for the REX.

Basis for Relief 'Each heat exchanger consists of an inlet-outlet head ' __ g chambor with one inlet and one outlet nozzle and two integrally attached support brackets. Volumetric examination of the nozzle-to-vessel welds and the nozzle inner radil is inhibited by the {.- shell-to-tubesheet weld, shell-to-head weld, and the , {- integral supports as shown in the attached sketches. Proximity of the welds and inner radius sections do not allow for the achievement of meaning results from a volumetric examination. Alternate Examination: The nozzle-to-vessel welds will be examined utilizing a surface examination only. Safety Evaluation Summary:

(Continued) Basis for Reli t1: Sequoyah Nuclear Plant (SON) is a four-loop pressurized water reactor with four inlet and four outlet RV nozzles. The RV nozzle-to-vessel welds and inside radius sections are ultrasonically examined {, . from the RV inside diameter using automated Inspection devices. With the RV core barrel in place, the outlet nozzles are accessible for
, examination from the nozzle bore only. The inlet
! nozzles are inaccessible for examination until the core barrel is removed.
I
- i. .
SQN is in the second period of the first ten-year inspection interval. During the first period, the accessible volumes of the nozzle-to-vessel welds and insido radius sections on SQN's fouc outlet nozzles were ultrasonically examined from the nozzle bore. The remaining examinations for the four inlet and
;- four outlet nozzles are to be completed during the third period, thus satisfying the requirements of Table IRB-2500-1, Examination Category B-D, Item Nos. ,
, B3.90 and B3.100, Footnotes 3, 4, and 5.
6 In addition to the RV nozzle examinations, the RV nozzle-to-safe end welds are ultrasonically examined i using an automated inspection device when the nozzle
, is examined from the bore. During the first period, the nozzle-to-safe end welds on four outlet nozzles g were ultrasonically examined from the inside diameter and surface examined from the outside diameter. The nozzle-to-safe end welds on the four inlet nozzles will be similarly examined during the third
{t inspection period. This will satisfy the requirements of Table IWB-2500-1, Examination Category B-F, Item No. B5.10, Footnote 2. The ASME Code provides for the continuation of the first and third period examinations during the second, third, and fourth inspection intervals, thus establishing a ten-year examination frequency. TVA , proposes to alter the inspection schedule by performing an additional examination of the RV
~ i, nozzle-to-vessel welds and inside radius sections for SQN's four outlet nozzles during the third inspection l
period of the fi.rst inspection interval. In addition, the razzle-to-safe end welds for the outlet nozzles would also be examined during the third inspectior period of the first interval. Pe rfo rmance of these additional examinations will thereby establish a new ten-year examination schedule for the l.m. secon4, third, and fourth inspection intervals. The (Continued)

REQUEST FOR RELIEF ISI-15 i (Continued) 1 Basis for Reliefs ten-year examination frequercy required by the code (Centinued) would continue to be maintaiaed. Additional benefits include: One-time installation and removal of the automated inspection device from the RV flange
, rather than twice during and inspection 3 serval.
Performance of additional RV outlet nozzle examinations during the first inspection interval, Performance of additional RV outlet nozzle-to-safe end weld examinations during - first inspection interval. An overall reduction in personnel radiation I exposure (one automated examination versus two), thus supporting as low as reasonably achievable considerations. ' A reduction in the number of times automated devices and associated materials and equipment must be decontaminated (reduces generation of radwaste). A cost saving to TVA of 1.8 million dollars over the 40-year life of the plant. t In consideration of TVA's performance of additional examinations during the first interval f-and the radiation exposure required to perform k inspections under the current Section XI examination schedule (second, third, and fourth q intervals), it is concluded that compliance with p" the specified requirements would result in an unnecessary hardship without a compensating
, increase in the level of quality and safety.
Alternate Insoection: SON's four RV outlet nozzles will be ultrasonically
*
- examined twice during the first inspection interval.
The second examination would occur during the third j period. This includes examination of the outlet nozzle-to-vessel welds by the straight beam ultrasonic method from the nezzle bore and examination of the outlet nozzle inner radius secticas.

The weld examinations are distributed in three segments of 15 feet lengths each inspection period. s The weld segments are identified as WO8-09A (0" - 180"),'W08-09B (180" - 360") and WO8-09C (360" - 540"). Due to the design configuration of the closure head, no examinations may be performed from the flange side. Limited examinations from tha head side are due to the head lifting lugs located at O*, 120', and 240' (see attached drawing). WOB-09A was ultrasonically examined in the first inspection perloo and achieved approximately 40% examination volume coverage. HOB-09B was examined in the second inspection period and achieved approximately 40% examination volume coverage. WO8-09C is scheduled for examination during the third period with an estimated examination volume coverage of 40%. It i should be noted that approximately 100% of the " weld" volume was examined from the OD surface f rom the ., closure head side. However, the required 1/2T base metal area was not completely examined on the flange side. Due to the limited scanning area, TVA will be able to achieve approximately 40% examination coverage of the RPV closure head-to-flange weld. Alternate Examination 1 In addition to the visual examination performed during system leakage and hydrostatic pressure tests,
, TVA will perform a best-effort ultrasonic examination to achieve as much code coverage as possible and achieve meaningful results. In addition, TVA will perform a 100% surface examination (MT) of all accessible areas of the closure head-to-flange weld
