Subject:
Second 10-Year Interval Inservice Inspection Program for Davis-Besse Nuclear Power Station (TAC No. M87188)
Gentlemen:
By' letter dated August 20, 1993 (Log Number 4060), the Nuclear Regulatory Commission (NRC) provided Toledo Edison (TE) with the results of their review of the "Second Ten-Year Interval Inservice Inspection Program Plan for Davis-Besse Nuclear Power Station, Unit 1",
Revision 3.
In this letter, the NRC stated they would not make a conclusion regarding the adequacy of the program plan until after meeting with the TE staff to discuss the open issues identified during their review. The TE staff met with the NRC staff on September 23, 1993 to discuss the open issues.
As a result of this meeting, TE agreed to resubmit Relief Request RR-B4 vith additional justification.
Revised Relief Request RR-B4 is enclosed as Attachment 1.
Tables showing the number and examination schedule of velds. subject to this relief request are provided in Attachment 2.
TE also agreed to perform an augmented surface examination of attachment velds for " thin vall" piping addressed by Relief Request RR-B4.
These examinations vill be performed on attachment velds meeting the requirements of Note 1 of Examination Category C-C.
Tables showing the number and examination schedule of the " thin vall" attachment velds are provided in Attachment 3.
In addition, the NRC's partial denial of Relief Request RR-A3 was discussed in the September 23 meeting.
In the Technical Evaluation F.epo r t (TER) included in the NRC's August 20, 1993 letter, the basis for partial denial was that the decay heat valve pit must be 4
opened to perform examinations of pipe velds and therefore, a VT-2 examination and hydrostatic test could be performed at this time.

Docket Number 50-346 License Number NPF-3 Serial Number 2204 Page 2 It is TE's intent to open the decay heat valve pit to perform the pipe veld examinations while the plant is in a mode where Technical Specification (TS) 3.5.2 (Emergency Cm = Cooling Systems) is not applicable (i.e., Mode 4, 5, or 6).
%e s 've pit must be resealed prior to entry into Mode 3 to meet TS 1 .4.
The hydrostatic test and system pressure tests of these components can only be performed with the plant in Mode 3 in order to meet TS 3.4.2 (Reactor Coolant System Safety Valves - Shutdown) and TS 3.4.9 (Reactor Coolant System Pressure / Temperature Limits). Therefore,. reopening the decay heat valve pit to perform the VT-2 examination during the hydrostatic test or system pressure tests would require entry into a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> Limiting Condition for Operation (LCO) action statement.
As was acknowledged in the TER, the valve pit cover cannot be recoved, reinstalled and satisfactorily tested during the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> time period.
Based upon the above discussion, TE requests that this Relief Request be reconsidered.
In order to support the upcoming refueling outage, TE requests that these Relief Requests be approved by October 1, 1994.
Should you have any additional questions regarding this information, please contact Mr. Villiam T. O'Connor, Manager - Regulatory Affairs, at (419) 249-2366.

Description:
ASHE Class 2 Emergency Core Cooling and Main Steam piping i
velds ASME Code Class:
ASME Section XI, Clas 2, C-F-1, Pressure Retaining Velds in Austenitic Stainless Scael or High Alloy Piping ASM6 Section XI, Class 2, C-F-2, Pressare Retaining Velds in Carbon or Lov Alloy Steel Piping ASME Examination Requirements:
Code Categories C-F-1 and C-F-2 require surface and volumetric examinations for piping velds greater than or equal to 3/8 inch nominal vall thickness for piping greater than 4 inch nominal pipe size.
For High Pressure Injection Systems, a surface and volumetric examination is required for piping velds greater than 1/5 inch nominal vall thickness for piping greater than or equal to 2 inch nominal pipe size and less than or equal to 4 inch nominal pipe size.
Per Note 2 of C-F-1 and C-F-2, velds not exempted by IVC-1220 which do not meet the above criteria do not require nondestructive examination, but are required to be included in the total veld count to which the 7.5% sampling rate is applied.
Basis for Relief:
Relief is requested from the minimum wall thickness requiring examination as specified in Code Categories C-F-1 and C-F-2.
The piping in the Containment Spray discharge, the Decay Heat Removal discharge, the Decay Heat Removal suction from the Reactor Coolant System Class 1 boundary, and the Hain Steam supply for the Auxiliary Feedvater Pumps from the Main Steam lines to the first isolation valve has a vall thickness less than 3/8 inch and greater than 1/5 inch. The piping in the Containment Spray suction, the High Pressure injection suction,'the High Pressure Injection recirculation line, the Decay Heat Removal suction from the Borated Vater Storage Tank, and the Decay Heat Removal suction from the Emergency Sump has vall thickness less than 1/5 inch.
This " thin vall" piping is not subject to any nondestructive examination under Code Categories C-F-1 or C-F-2.
l
. Docket Number 50-346 i
License Number WPF-3 Serial Number 2204 Attachment l' Page 2 When the selection criterion of C-F-1 and C-F-2 Note 2 is applied to these systems, approximately 93% of the Class 2-Decay Heat Removal discharge velds past'the Containment Isolation Valves, approximately.26% of'the High Pressure Injection discharge, and approximately 11% of the Main Steam System velds receive a nondestructive examination per Examination Categories C-F-1 and C-F-2.
These sampling rates exceed the 7.5% sampling rate established in ASME Section XI.
In addition, the velds requiring examination in the Emergency Ccre Cooling Systems are concentrated in approximately 1/3 of the total velds in the systems. This distribution is such that the requirements of C-F-1 and C-F-2 Note 2 can not be met.
Toledo Edison believes that appropriate nondestructive examination of circumferential velds in the " thin vall" portion of these systems is is warranted.
Volumetric examinations are not appropriate for all piping vall thicknesses.
Volumetric examination requirements are established in Appendix III of ASME Section XI.
These requirements are not applicable to piping with a vall thickness less than 1/5 inch.
Code Case N-435-1 provides alternative ASME Section XI examination requirements for vessels with a vall thickness of 2 inches or less. This Code Case states that a surface examination may be applied in lieu of volumetric examinations for vessels with a-vall thickness 1/5 inch or less. This Code Case recognizes that volumetric examination of welds with a vall thickness less than 1/5 inch to ASME Section XI requirements is impractical.
Longitudinal velds adjacent to circumferential velds also require examination under Code Categories C-F-1 or C-F-2.
In
" thin vall" piping, the area of interest for longitudinal velds is nearly or completely encompassed by the required circumferential veld examination surface area depicted in Figure IVC-2500-7.
Alternative Examination:
The minimum nominal vall thickness specified in Code Categories C-F-1 and C-F-2 vill not be used to exclude velds from examination in the Containment Spray, Decay Heat Removal, High Pressure Injection, or Main Steam systems. The following requirements vill be used to establish examination requirements for C-F-1 and C-F-2 category velds in these systems.
- ' The 7.5% sampling rate vill be applied to all non exempt velds.
- Velds selected which meet the nominal vall thickness requirements of Code Categories C-F-1 and C-F-2 vill receive surface and volumetric examinations.

License Number NPF-3 Serial Number 2204
- Attachment 1 Pa'ge 3
- Velds in piping greater than NPS 4 with vall thicknesses between 1/5 inch and 3/8 inch vill receive an augmented surface and volumetric examination.
- Velds in piping vall thicknesses less than 1/5 inch vill receive an augmented surface examination.
- Longitudinal velds vill not be subjected to separate examinations.
