" Alternative Rules for the Selection and l Examination of Class 1,2, and 3 Integrally Welded Attachments", Section XI, Division 1 i in lieu of the 1989 Edition of ASME Section XI as stated above. + Basis for Relief: In many cases, performing a surface examination on Class 1 and Class 2 integrally l welded attachments requires the removal of pipe clamps. Pipe clamp removal is labor intensive and often destroys bolting in the process. Pipe clamp removal on larger components such as those found on the Main Steam and Feedwater Systems are particularly difficult. Sequoyah did not identify any significant problems with integrally welded attachments in the first ISI Inspection Interval. The costs for preparing and examining integrally welded attachments are significant, as is the attendant additional radiation exposure. Code Case

- ~ _ - -.. _. - - -.. - - - i SEQUOYAH NUCLEAR PLANT j REQUEST FOR RELIEF 1-ISI-5 N-509 provides an overall cost savings and exposure reduction without compromising safety or quality. By utilizing Code Case N-509 the number ofintegral attachments requiring examination is reduced for Classi integrally welded attachments where base material design thickness is 5/8" or greater, Class 2 integrally welded attachments where base material design thickness is 3/4" or greater, and Class 3 integrally welded attachments. However Code Case N-509 increases the Class 1 and 2 integral attachment population for certain areas due to the elimination of the material design base thickness exemption and for Class 3 integrally welded attachments a more stringent visual examination method (VT-1 in lieu of a VT-3) is required. Alternate Examinations: The examination requirements of Code Case N-509 will be used as an alternative to the examination requirements of the 1989 Edition of ASME Section XI, Division 1. Note: Code Case N-509 requires selection of component apports for examination in accordance with IWF of the 1990 Addenda. ) Sequoyah will implement Code Case N-509 l uti!izing Code Case N-491, which contains the j same requirements for selection of component supports for examination as the 1990 Addenda. Code Case N-491 has been approved for use in Regulatory Guide 1.147. SQN will perform surface examinations on 10% of Class 1 and Class 2 integral attachments (on piping, pumps and valves) associated with the component supports selected for examination in accordance with Code Case N-509. Note: SQN will perform visual examinations (VT-1) on 10% of the integral attachments of Class 3 piping, pumps, and valves.

ITEM 2.C. As requested SQN is providing additional information for Requests for Relief 1-ISI-3, (Unit 1) and 2-ISI-3 (Unit 2) in order to seek relief from examining integrally welded attachments and component supports in Auxiliary Feedwater System (AFW) on lines NPS 1 and smaller.

1 a i ITEM 2.C. l f SQN stated that it was an unnecessary burden to examine the integrally welded attachments l and component supports on NPS 1 and smaller piping in the ASME Class 3 Auxiliary i Feedwater System. The 1989 Edition of ASME Section XI has no requirements to examine l integrally welded attachments on NPS 1 and smaller piping in ASME Class 1 and 2 systems. i DISCUSSION l The 1991 Addenda resulted in essentially no changes in piping examination requirements for 1 Class 1 and 2, but Class 3 requirements included an examination scope decrease. The incorporation of the NPS 1 and smaller exemption for Auxiliary Feedwater Systems in the { 1991 Addenda appeared to be added due to an omission in the 1989 and earlier Editions. There is no reason to impose more stringent requirements for Class 3 components than those j required for Class 1 and 2. i l The Auxiliary Feedwater System (AFW) at SQN consists of two motor driven pumps and one turbine driven pump for each Unit. Each of the motor driven pumps supplies feedwater to two steam generators and the turbine driven pump supplies feedwater to all four steam generators. Normal suction for the AFW pumps is supplied by the condensate storage tanks. A backup safety related source is from the Essential Raw Cooling Water (ERCW ) system. Additionally the fire protection system can be aligned to AFW to supply water to the steam generators during a flood. The attached Table 2C gives a summary of the AFW lines associated with the motor driven pumps, turbine driven pumps and steam generators. j Based upon initial walkdowns the number ofintegral attachments is low, approximately 11 per unit. The design of the type of supports used with the integral attachments on these lines (NPS I and smaller) are very strongly constmeted. They consist of a length oflarger diameter pipe which is penetrated by the NPS I and smaller line at right angles. The smaller line is then welded at both ends to the larger diameter pipe using a full circumference fillet weld. The larger diameter pipe only serves as a support and is welded to a process line at one end. Tids type of construction provides substantial bracing independent of the welds and therefore any potential damage to the welds would not significantly impact the function of the support. Problems with these integral attachments are not anticipated to cause any loss of function of the associated NPS I and smaller line. The adoption of Code Case N-509 is not a reduction of 90% of the required examinations for integrally welded attachments, but rather requires a 10% sample of all Class 3 non-exempt integrally welded attachments. Code Case N-491, which was authorized for use by Regulatory Guide 1.147, could actually reduce the number ofintegral attachments required to be examined due to the 1989 Code requirements that 10% of the integrally welded attachments associated with the component supports selected for examination require examination. By adopting Code Case N-509, SQN proposes to examine 10% of all non-exempt integrally welded attachments for Class 3. Based on the reasons stated above, SQN believes the proposed examination plan v.ith the associated Request for Relief satisfies ASME Code requirements without any reduc

• ion in quality and safety.

SEQUOYAH NUCLEAR PLANT REQUEST FOR RELIEF 1-ISI-3 and the integrally welded attachments on this piping would be labor intensive. The identification j process would require walkdowns of vent lines, drain lines, i instrumentation lines and sampling lines. Subsequent to the walkdowns, substantial resources will be required to sketch the applicable lines. Further resources will be required to check, verify and maintain the resulting sketches. NPS I and smaller piping is not analyzed for pipe rupture, due to the low safety significance associated with rupture of these lines. Sequoyah did not identify any significant problems with integrally welded attachments during the first inspection interval. ASME Section XI Codes 1991 Addenda and later incorporated the NPS 1 and smaller exemption requirements for Auxiliary Feedwater System. The exemption includes piping NPS 1 and smaller and exemptions for vessels, pumps, and valves and their connections in piping NPS 1 and smaller. Sequoyah believes that it is an unnecessary burden to inspect supports and integrally welded attachments on NPS 1 and smaller piping in the Class 3 Auxiliary Feedwater System. The inspection of these items willimpose costs without compromising the safety or quality of the unit.

i SEQUOYAH NUCLEIR PLANT REQUEST FOR RELIEF 1-ISI-3 Examinations Performed: SQN will perform examinations as required by the 1989 Edition of ASME Section XI Code on the non-exempted components greater than NPS 1 na the ASME Code Class 3 PWR Auxiliary Feedwater System. Justification: This request is to use only the NPS I and smaller exemption on Auxiliary Feedwater System piping. It is an unnecessary burden to examine supports and integrally welded attachments on NPS I and smaller piping in the Class 3 Auxiliary Feedwater System. Even for the Class 1 and 2 systems in the 1989 Edition of ASME Section XI, there are no requirements to examine supports and integrally welded attachments on NPS 1 and smaller. Prior to the Winter 1980 Addenda, there was no requirement to examine Class 3 NPS I and smaller Auxiliary Feedwater System piping supports and integrally welded attachments. The later 1991 Addenda IWD-1220 incorporated the NPS 1 and smaller exemption to provide clarification on the exemptions. Problems with these integral attachments are not anticipated to cause any loss of function of the associated NPS 1 and smaller line.

== Conclusion:== Based on the abovejustification,it is concluded that the code requirement of no exemption for the NPS I and smaller on the Auxiliary Feedwater System is impractical.
