Description:
Alternate Testing for Class 1, Class 2, and Class 3 Welded Repaired/Replaced Components.
Component Numbers: All Class 1, Class 2, and Class 3 pressure retaining components subject to Hydrostatic Testing per IWA-4700.
COPE REQUIREMENT The 1989 Edition of ASME Section XI, IWA-4700(a) requires a hydrostatic test to be performed per IWA-5000 after welded repair/replacement of classed components, except those exempted by IWA-4700(b).
A-5214 requires a pressure test per IWB-5222, IWC-5222, or IWD-5223, as applicable to the system ich contains the repaired or replaced component.
IWB-5222, IWC-5222, and IWD-5223, System Hydrostatic Test, require a Test Pressure of 1 ..02 to 1.10 times P0 for Code Class 1 components, 1.10 or 1.25 times Psv (or Pd or Pg) for Code Class 2 components, and 1.10 or 1.25 times Psv (or Pd or Pgl for Code Class 3 components, where P0 is the nominal operating pressure corresponding with 100.% rated reactor power,-Psv is the-lowest 'pre-ssi.ire
.. setting among *the safety or relief valves provided for overpressure protection within the boundary of the system:to be tested, Pd is the system design pressure, and Pg is design pressure of vapor or gas space above *liquid level within an atmospheric storage tank for which overpressure protection is provided by relief valves. '
- BASIS FOR RELIEF Pursuant to 10CFR50.55a(a)(3)(i), relief is requested on the basis that the proposed alternatives provide an acceptable level of quality and safety.
Due to the additional preparation required to safely accomplish the required System Hydrostatic Tests (at pressures above normal operating levels) after welded repairs and replacements on Code Class 1, 2, and 3 components, these tests present unusual difficulties and often hardship situations for Palisades Nuclear Plant.
Some of the specific problem~ typically encountered when preparing and performing these tests include:
- - Complicatetl or abnormal valve line-ups in order to properly vent, fill, and isolate the component requiring testing.
Proc No EM 1 3 Attachment 4 Revision 2 Page 3 of 9 RELIEF REQUEST N.UMBER: PR~Ot (Page 2 of 3)
BASIS FOR RELIEF (Cont'd)
- Relief valves with setpoints lower than the hydrostatic test pressure must be gagged or removed .
and blind flanged. This process requires the draining and refilling of the system both prior to the test and prior to system restoration.
- Valves that are not normally used for isolation (eg, normally open pump discharge valves) are often required to provide pressure isolation for an elevated pressure hydrostatic test. These valves frequently require time consuming seat maintenance in order to obtain a leak tight pressure boundary.
- The radiation exposure to Plant. personnel
. involved in hydrostatic tests is high in comparison to operational pressure testing due to the large amount of time required to prepare the volume for testing (ie, installing relief valve gags, performing appropriate valve line-ups, completing valve maintenance, filling and venting, etc).
The difficulties encountered in performing a hydrostatic pressure test are prohibitive when weighed against the benefits. Industry experience; which is supported by Palisades' experience, shows that most ,.
rough wall l~akage is detected during system operation as opposed to during elevated pressure tests
- uch as ten-year or post-maintenance system hydrostatic tests.
- No leakage detection benefit is gained, from the added challenge to the piping system provided by an elevated pressure hydrostatic test as compared to a system operational test. The stresses experienced during a hydrostatic test do not include the significant stresses associated with the thermal growth and dynamic loading seen during a system operational test. Thus, the ~yst~m.is more .likely to experience any
- througb_'Jli'all leakage,.at operating conditions due to the combination of dynamic/thermal loading and the normal op-erating pressure parameters than during the careful, slow pressurization of a hydrostatic .test.
These arguments are also supported by Code Case N-498, "Alternative Rules for 10-Year Hydrostatic Pressure Testing for Class 1 and 2 Systems,Section XI, Division 1." This relief request is a logical extension of that Code Case. Code Case N-498 is approved for use in Regulatory Guide 1.147, Revision 11. In addition, the ASME Board of Nuclear Codes and Standards has approved Code Case N-416-1, "Alternative Pressure Test Requirements for Welded Repairs or Installation of Replacement Items by Welding, Class 1, 2, and 3 Systems,Section XI, Division 1," which incorporates the logic and Alternative Examinations contained within this relief request.
Based on the above, Palisades Nuclear Plant requests relief from the ASME Section XI requirements for performing elevated pressure hydrostatic tests on Class 1, Class 2, and Class 3 repaired/replaced components .

PROPOSED AL TERN ATE PROVISIONS After welded repairs or installation of replacement items by welding, the following alternative requirements will be met in lieu of performing the hydrostati_c pressure test required per paragraph IWA-4000:
(a) NOE shall be performed in accordance with the methods and acceptance criteria of the applicable Subsection of the 1992 Edition of Section Ill.
(b) Prior to or immediately upon return to service, a visual examination (VT-2) shall be performed in conjunction with a system leakage test, using the 1992 Edition of Section XI, in accordance with paragraph IWA-5000, at nominal operating pressure and temperature.
(c) . Use of this Relief Request shall be documented on an NIS-2 Form.
(d) When NOE is to be conducted per .Subsection N0-5222 on a Code Class 3 component, an additional surface examination shall be performed on the root (pass) layer.
(e) When Code Class 3 repair or replacement activities involve socket/fillet welds, a surf ace examination shall be performed on the subject socket/fillet welds.
These methodologies are specified in Code Case N-416-1 as approved by the Board of Nuclear Codes and Standards, with the additional NOE of (d) and (e) above.
APPLICABLE TIME PERIOD Reliel is requested for the third ten-year interval of the lnservice Inspection Program for Palisades, which
~
I concludes in August 2005. Use of this Code Case has been approved by the NRC (TAC NO M91764)

Alternative Testing for Compone.nts Under the Reactor Vessel CODE REQUIREMENT IWA-5211 states that the pressure retaining components within each system boundary shall be subject to system pressure tests as specified in Table IWA-5210-1 under which conditions VT-2 Visual Examinations are performed.
Table IWA-5210-1 requires a system leakage test and a system hydrostatic ~est be performed in ccordance with Table IW8-2500-1, Category 8-P.

BASIS FOR RELIEF Pursuant to 10CFR50.55a(a)(3)(ii), relief is requested on the basis that the specified requirements above would result in hardship and unusual difficulty without a compensating increase i.n the level of quality and safety. Also, per *1 OCFR50.55a(a)(3)(i), the proposed alternate examination will provide an acceptable level of quality and safety.
- The area under the reactor vessel is extremely hazardous when the Plant is at Hot Shutdown Conditions for system leakage testing. Radiation levels are expected to be greater than 5-10 rem/hr (on contact),
which is the maximum measured during cold shutdown. Assuming 2 persons at one hour per person in this area a total of 10 to 20 rem of dose would be received.
In addition to radiation concerns, access to the area under the vessel posses various industrial hazards.
Of primary concern is confined spaces and heat stress. Ambient air temperatures with the Primary Coolant System at full pressure and temperature are expected to be approximately 300 degrees. Access nder these conditions would require significant ventilation for cooling. The access tube to this area is nly 30 inches in diameter. This size limits the amount of ventilation possible while allowing personnel access.
Proc No EM 13 Attachment 4 Revision 2 Page 6 of 9 RELIEF REQUEST NUMBER: PR-02 (Page 2 of 2)
PROPOSED AL TERNA TE EXAMINATION Palisades Nuclear Plant shall determine leakage from piping and components in the area under the reactor vessel in accordance with paragraph IWA-5244 "Buried Components" of ASME Section XI, 1989 Edition, no Addenda. This requirement will be satisfied by the conducting of Palisades' System Operating Procedure SOP 1, "Primary Coolant System (PCS)," which completes the PCS leak rate calculation. Plant Technical Specification 3.1.5 states, "If the primary coolant system leakage exceeds 1 gpm and the source of the leakage is not identified, reduce unidentified primary coolant system leakage to less than 1 gpm within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, or place the reactor in hot shutdown within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in cold shutdown condition within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />." Technical Specification 3.1.5d place invokes a more restrictive leakage limit of 0.6 gpm during startups. Technical Specification Table 4.2.2, Item 7 requires this leak rate determination on a daily basis. These limits are approved as documented in Palisades Facility Operating License DPR-20, through Amendment No 161 and are applicable at all times when the Primary Coolant System is greater than cold shutdown conditions.
APPLICABLE TIME PERIOD elief is requested for the third ten-year interval of the lnservice Inspection Program for Palisades, which ncludes in August of 2005.

Code Class: 1, 2, and 3
Subject:
10-Year hydrqstatic pressure test requirements for Class. 1, 2 and 3 systems.
- Components: All Class 1, 2, and 3 piping systems which are subject to the pressure test requirements of ASME Section XI.
Code Requirements Reference ASME Section XI 1989 Edition A system hydrostatic pressure test (IWA-5211 d) and accompanying VT~2 is required at least once each inspection interval(nominally 10 years). Reference Table IWA-5210-1, Categories B-P (Class 1), C-H (Class 2), D-A, D-B, and*o-c (Cfass 3).
Performance of system hydrostatic pressure tests imposes an undue hardship without a compensating increase in nuclear safety. The amount of effort expended in repairing system boundary valves, which are not designed for leak tight shutoff, in order to successfully complete. testing is not compensated for by an increase in safety. Additionally, removing systems from. service to comple~e_ hydrostatic testing poses a risk to safeJy by isolating cooling-water from important Plant loads, such as, Spent Fuel Pool cooling anci"shutd9wn cooling. . . .
Code Case N-498, currently endorsed by the NRC in Regulatory Guide 1 . 147, allows Class 1 and 2 System Hydrostatic testing at a reduced pressure equal to system nominal operating pressure. The recent ASME approved Code Case N-498-1, while repeating these requirements for Class 1 and 2, also clarifies the ,intent of using installed Plant instrumentation without the need for test gauging or their imposed requirements of IWA-5260 when performing these nominal operating pressure tests.
It is Palisades' position that performing system pressure tests on Class 1 and 2 systems consistent_ with the requirements of N-498-1, together with the applicable volumetric examinations in accordance with the ISi Program, provides a level of quality and safety equivalent to, or greater than, that provided by the Code hydrostatic test pressure and instrumentation requirements.
- Code Case N-498-1 also permits the reduced pressure testing in lieu of Hydrostatic Tests for Class 3 systems. Palisades Class 3 systems include portions of Chemical and Volume Control, Component Cooling, Service Water,

Auxiliary Feedwater and Spent Fuel Pool Cooling Systems. Each of these systems is designed, fabricated, constructed, and tested in a manner which assures pressure boundary integrity. Additionally, each system receives chemical treatment and/or monitoring to assure continued pressure boundary integrity.
The Auxiliary Feedwater System receives water from the Condensate Storage Tank T-2. The water contained in T-2 is filtered and demineralized to reduce corrosion of system components.
In the Component Cooling System, nitrite concentration is maintained to provide corrosion protection.
The nitrate inhit:>itor acts to create and maintain a passive oxide layer on the internals of the Component Cooling System. Sampling and analysis of system chemistry is performed at a frequency adequate to maintain proper corrosion inhibiting conditions.
- For the Service Water System, Palisades employs a program designed to ensure corrosion,* erosion, silting; biofouling, and protective coating degradation are controlled so that safety-related components are not at risk. This program includes chlorination, zebra mussel chlorination treatment, inspections and coupon analysis. This program is also designed to control Microbiologically Influenced Corrosion (MIC).
he portion of Chemical .~nd Volume Control between the Clas-s 1 portion of letdown and the containment penetration has been designated as Class 3 in accordance with Regulatory Guide 1. ?6. The CVCS is designed to maintain Primary Coolant System chemistry, therefore, appropriate conditions are maintained through the use of filtration and addition of Boron, Hydrogen, Nitrogen, and other chemicals.
Spent Fuel Pool chemistry is maintained through the use of Primary Make-up water and Boron. System design makes extensive use of st~inless steeJ tp reduce corrosion con_cerns_; Chemistry* co'iitaminant lir.:nits are c_onsisteht witti that of the Primary Coolant System, bec*ause Spent Fuel Pool water may enter the PCS when refueling is in process.
System chemistry for all Palisades safety systems is maintained by approved Plant procedures. The
- purpose of chemistry control is to assure operationaf readiness by inhibiting degradation mechanisms which may compromise pressure boundary integrity.
Palisades maintains Visual Examination VT-2*certifications for all Auxiliary Operators and other* selected individuals, who meet the educational, experience, and physical requirements of ANSl-N45.2.6. The VT-2 program provides training to assist operators in determining the pressure boundary integrity of all Plant systems during daily rounds. Operators are trained to recognize evidence of leakage, as well as, actual system leakage. Operator use of VT-2 Examination training provides additional assurance of pressure boundary integrity for all class systems.

It is Palisades' position that performing system pressure tests on Class 3 systems consistent with the requirements of N-498-1, together with the implementation of chemical control and VT-2 examination programs, provides a level of quality and safety equivalent to, or greater than, that provided by the Code hydrostatic test pressure and instrumentation requirements.
Proposed Alternative As a supplement to existing Section XI requirements, Palisades will adopt the provisions of Code Case N-498-1, as approved by the Board of Nuclear Codes and Standards (BNCS).
, In lieu of performing a hydrostatic pressure test at a pressure above nominal operating pressure or system pressure for which overpressure protection is provided, as required by Table IWA-5210-1, Examination Categor.ies 8-P, C-H, D-A, D-8, and 0-C, a system pressure test at nominal operating pressure and temperature shall be performed.
In lieu of instrumentation requirements specified in IWA-5260, existing Plant instrumentation will be used r IWA-521 ~(b). Where gauging niay be required and does not exist, the rules of IWA-5260 shall be ed.
Palisades shall continue to implement chemical control programs for safety systems. These programs shall be designed to assure system pressure boundary integrity by inhibiting erosion, corrosion, biofouling, MIC, and other identified degradation mechanis'ms.
- Palisades shall continue to maintain a Visual . Examination VT-2 :Program.
APPLICABLE TIME PERIOD Relief is requested for the third ten-year interval of the lnservice Inspection Program for Palisades, which concludes in August of 2005. Use of this Code Case has been approved by the NRC (TAC NO M91410) until the Code Case N-498-1 is included in Regulatory Guide 1 . 147.
