===1.1 Overview===
1OCFR50.55a and the South Texas Project (STP) Technical Requirements Manual invoke inservice testing (IST) of Snubbers per ASME OM Code (Code of Operation and Maintenance of Nuclear Power Plants). Part 50.55a establishes the requirements that each nuclear power plant must develop and implement an inservice inspection and testing program. Inservice tests are used to verify operational readiness of Snubbers whose function is required for safety. The tests conducted during successive 120-month intervals must comply with the requirements of the latest edition and addenda of the OM Code that is in effect 12 months prior to the start of the interval.Title 10, Part 50.55a of the Code of Federal Regulations invoke, by reference, the requirement for inservice inspection (ISI) of Snubbers per Section XI of the ASME Boiler and Pressure Vessel Code.STP begins its third IST 10-year interval of commercial plant operation for Unit I & 2 on September 25, 2010 and ends on September 24, 2020.The Snubber Inservice Test Plan was developed in accordance with the requirements of I OCFR50.55a that became effective on October 15, 2008.The edition and addenda of the ASME OM Code for the Snubber IST Program for the third 10-year interval is the 2004 Edition No Addenda, Subsections ISTA & ISTD [the Code].1.2 Program Test Plan Since the period of time that the requirement for inservice testing was first incorporated into the Code of Federal Regulations; the NRC, ASME, and the nuclear industry have provided additional interpretations to the Code requirements.
These interpretations have been documented through various mechanisms such as 1 OCFR50.55a Final Rules, Code Cases, Code Interpretations, generic letters, program review meetings, site inspections, and others. It is the intent of the Program Plan to: 0 Establish a set criteria and philosophy for determining the Snubber Testing Scope,* Evaluate each plant Snubber in a consistent manner to identify which Snubbers SHOULD be included in the testing program and to identify the extent,* Identify Alternative requirements to the Code,* Identify implementation processes of testing required for each snubber, and implementing documents.
Revision 0 Page 1 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan 2.0 SCOPE 2.1 Overview The scope of the Snubber IST Program includes those Snubbers that are required to perform a specific function in shutting down the reactor to a safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident.This program was developed to encompass system safety requirements defined in 10 CFR 50 as well as Snubber functions required in response to the abnormal operational transients and accidents defined in the UFSAR. The program is not limited to the postulated accidents of UFSAR Chapter 15. The UFSAR, Technical Specifications, and related design basis documents are the primary references used to determine which Snubbers are required to perform specific functions related to the spectrum of postulated accidents.
The only snubbers excluded from this program are those installed on nonsafety-related systems, and then only if their failure or failure of the system on which they are installed would have no adverse effect on any safety-related system.2.2 Code Classification The quality group classification system for water, steam, and radioactive waste containing components important to the safety of water-cooled nuclear power plants is established by NRC Regulatory Guide 1.26, in conjunction with 1 OCFR50.55a.
Regulatory Guide 1.26,"Quality Group Classification and Standards", defines the Quality Group Classification System consisting of four Quality Groups, A through D. Quality Group A is defined as"Reactor Coolant Pressure Boundary" (Class 1) by I 0CFR50.2.
The definitions of Groups B, C, and D (Class 2, Class 3 and non-classed, respectively) are provided by Regulatory Guide 1.26.Revision 0 Page 2 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan 2.3 Snubber IST Listing The Snubber IST Listing was previously known as the Snubber Index prior to invoking ASME OM Code. The Snubber IST Listing is maintained as the Snubber Database, which is an electronic database containing component test and inspection history, acceptance criteria, and references.
The Snubber Database is used to identify snubbers to be tested in accordance with the requirements of the Code. The Snubber Database contains, as a minimum, the following information about each Snubber:* Snubber identification (Snubber number, model number, and serial number)* Applicable plant system* ASME Code class (same as Quality Group Classifications in R.G. 1.26)* Snubber location information
* Test or examination method* Test and examination history Reference Attachment 1 (Unit I Snubber IST Listing) & Attachment 2 (Unit 2 Snubber IST Listing) for a listing of snubbers tested and examined in accordance with this plan.The listing provides basic information about the scoped snubbers.2.4 Implementing Processes Program inservice tests required by the Code SHALL be implemented using the Surveillance Test Program process. The Surveillance Test Program provides acceptance criteria for the tests and examinations.
As a result of the performed tests, any identified corrective actions and subsequent retests SHALL be made per the requirements of the Code and the ASME Section XI Repair/Replacement Program.In conjunction with the Surveillance Test Program process, other STP site documents detail Code requirements and implementation processes
[test or examination methods and frequency or schedule].
The Condition Reporting (CR) process at STP provides a method to document material deficiencies and engineering evaluations required to comply with the Code. Work orders initiated by the CR process will be used to implement corrective maintenance on snubbers identified for Inservice Testing and will allow for recording and tracking component history.Revision 0 Page 3 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan 2.5 Applicable Documents The details of the Snubber IST Program referenced in this Test Plan are contained in documents that are available at STP. These documents include, but are not limited to, piping and instrumentation diagrams, piping isometric drawings, component support drawings, and procedures that support implementation of the Snubber IST program.2.5.1 Piping and Instrumentation Diagrams (P&IDS)This section provides a listing of the various piping and instrumentation diagrams applicable to the Snubber IST Program. Table 1 provides a listing of the piping systems containing Class 1, 2, or 3 snubbers, and applicable Instrumentation Diagrams (P&ID's) for these Class 1, 2, and 3 piping systems. Table 1 is arranged in alphabetical system abbreviation.

===3.0 METHOD===
OF EVALUATING SNUBBERS The Master Equipment Database and system design basis documents were reviewed to determine which systems include snubbers that encompass system safety requirements defined in 10 CFR 50 as well as snubbers required in response to the abnormal operational transients and accidents defined in the UFSAR. This review was not limited to the postulated accidents of UFSAR Chapter 15.Each system was reviewed in the following manner: The P&ID for each system was reviewed to identify the system boundaries for each class of snubbers that are subject to a specific function in shutting down a reactor to the safe shutdown condition, maintaining the safe shutdown condition, or in mitigating the consequences of an accident.Each snubber was reviewed for design and installation arrangement for allowances for adequate access and clearances for conduct of tests.The Snubber IST Listing was developed from the above review activities.
Revision 0 Page 13 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan 4.0 ALTERNATIVE REQUIREMENTS TO OM CODE This section lists the alternative requirements to the Code for specific portions of the Snubber IST Program. The alternative requirements identified meet the rules for alternative requirements that are .defined in the Code.4.1 Code Cases Code Cases to be used during a preservice or inservice test examinations SHALL be identified in the Test Plan [ISTA 3130(a)].Code Cases SHALL be applicable to the edition and addenda specified in the Test Plan [ISTA 3130(b)].Code Cases SHALL be in effect at the time the test plan is filed [ISTA 3130(c)].Code Cases issued subsequent to filing the Test Plan MAY be proposed for use in amendments to the Test Plan [ISTA 3130(d)].Superseded Code Cases approved for use MAY continue to be used [ISTA 3140].Code Cases approved for use MAY be used after annulment for the duration of the Test Plan [ISTA 3150].Endorsement of Regulatory Guide 1.192 "Operation and Maintenance Code Case Acceptability, ASME OM Code", does NOT commit the STP to all code cases listed therein, but rather allows for selection of applicable code cases. The purpose of this endorsement is to identify all code cases that could potentially be incorporated into this IST Program Plan.4.2 1 OCFR50.55a Requirements
-Code Cases 1 OCFR50.55a(b)(6) addresses the application of Code Cases and states the following criteria: Licensees MAY apply the ASME Operation and Maintenance Nuclear Power Plants Code cases listed in Regulatory Guide 1.192 without prior NRC approval subject to the following:
When a licensee initially applies a listed Code case, the licensee SHALL apply the most recent version of that Code case.Revision 0 Page 14 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan If a licensee has previously applied a Code case and a later version of the Code case is incorporated, the licensee MAY continue to apply, to the end of the current 120-month interval, the previous version of the Code case as authorized or MAY apply the later version of the Code case, including any NRC-specified conditions placed on its use Application of an annulled Code case is prohibited unless a licensee previously applied the listed Code case prior to it being listed as annulled in Regulatory Guide 1.192. If a licensee has applied a listed Code case that is later listed as annulled in Regulatory Guide 1.192, the licensee MAY continue to apply the Code case to the end of the current 120-month interval.4.3 Code Case Adoption: 4.3.1 Adoption of Code Cases Accepted for Generic Use in Regulatory Guide 1.192 Code cases that are designated "Acceptable" or "Conditionally Acceptable" for generic use in Regulatory Guide 1.192 (latest revision) have been adopted for use by listing them in Table 3. All conditions or limitations delineated in Regulatory Guide 1.192 for applicable code cases will apply.4.3.2 Adoption of Code Cases Not Accepted for Generic Use in Regulatory Guide 1.192 via Submittal of Relief Requests Adoption of code cases that have been approved by the ASME Board of Nuclear Codes and Standards, but that have NOT been accepted for generic use in Regulatory Guide 1.192, MAY be submitted in the form of a relief request in accordance with 1OCFR50.55a(a)(3).
Once approved, these relief requests will be available for use by STP. The Relief Request is approved for use until the end of the 10-year interval in which it was approved.Table 4 lists those code cases for which relief requests have been submitted.
In addition to the requirements stated in the code cases, criteria MAY be stipulated in the relief request OR MAY be agreed upon through subsequent correspondence with the NRC. STP will implement these additional requirements as applicable.

Subsection ISTD. Article IWF-5000, "Inservice Inspection Requirements for Snubbers," of the ASME BPV Code, Section XI, provides inservice inspection requirements for examinations and tests of snubbers at nuclear power plants. Licensees MAY use Subsection ISTD, "Inservice Testing of Dynamic Restraints (Snubbers) in Light-Water Reactor Power Plants," ASME OM Code, 1995 Edition through the latest edition and addenda incorporated by reference in paragraph (b)(3) of this section, in place of the requirements for snubbers in Section XI, IWF-5200(a) and (b) and IWF-5300(a) and (b), by making appropriate changes to their technical specifications or licensee-controlled documents.
Preservice and inservice examinations must be performed using the VT-3 visual examination method described I in IWA-2213.Revision 0 Page 18 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan 5.0 INTERPRETATIONS TO THE OM CODE This section lists interpretations to the Code for specific portions of the Snubber IST Program.Code interpretations provide clarification to the intent of Code requirements.
Although the NRC agrees with most interpretations, some are inconsistent with NRC requirements.
NRC requirements SHALL be met. Interpretations serve to support the users understanding of Code requirements.
Many interpretations address specific circumstances.
Therefore, the context of the interpretation must be thoroughly understood prior to its application at STP.Code interpretations applicable to Snubber IST Program are listed in Table 7.TABLE 7 OM CODE INTERPRETATIONS Interpretation Interpretation Description
/ Subject Application No. Impact 04-10 ASME Code- 1998 through OMb-2000 Snubber testin 6.0 PROGRAM IMPLEMENTATION The Snubber Testing Program procedure (OPGP03-ZE-0009) details program implementation based on the Code and alternate requirements of the Code.Snubber program inservice tests required by the Code SHALL be implemented using the Surveillance Test Program. The snubber surveillance test program SHALL be used to identify the test method for verifying operational readiness of the snubber, to identify the frequency of the required tests, to establish plant conditions for performing tests, and to document the results of snubber testing. The surveillance tests act as the record of testing required by the Code.Reference Table 2 for a listing of the applicable snubber ITS program implementing procedures.
Revision 0 Page 19 of 20 SOUTH TEXAS PROJECT ELECTRIC GENERATING STATION Unit 1 and 2 Snubber Inservice Test Plan 7.0 PROGRAM CONFIGURATION CONTROL As a minimum the program will be reviewed and revised as necessary for compliance with the Code in effect as referenced by 1OCFR50.55a 12 months prior to the end of the third 120-month interval of commercial operation.
Additionally, the scope of the program is subject to revision due to changes in system design, changes in design that affect the snubber safety function, or revisions to the applicable code requirements through Alternate Requirements to the Code. In order to accommodate these changes STP reserves the right to submit program revisions that will enhance or improve the program at any time within the effective interval.8.0 TEST PLAN ATTACHMENTS Attachment 1, Unit 1 Snubber IST Listing Attachment 2, Unit 2 Snubber IST Listing Attachment 3, Code Cases -Information Only Attachment 4, Interpretations

==Subject:==
ASME Code-1998 through OMb Code-2000 Date Issued: December 12, 2005 File: OMI 05-04 Question (1): Reference ISTD-4240 and 4252(d). If a snubber reauires further evaluation or is classified as unacceptable during inservice examination and subsequently satisfies the operational readiness test criteria of ISTD-5210, is the snubber required to be classified as unacceptable for the purpose of deter-mining the subsequent visual examination interval in accordance with Table ISTD-4252-1?
Reply (1): No. Per ISTD-4240, test results that satisfy the operational readiness criteria of ISTD-5210 shall be used to accept the snubber., provided the test demonstrates that the unacceptable condition did not affect operational readiness.
In such cases, the visual examination requirements of LSTD-4230 are considered to be satisfied.
Question (2): It appears that ISTD-5200 and 5240 are conflicting as to when operational readiness testing can be performed.
May inservice operational readiness tests be performed on snubbers at any time during a fuel cycle, normal system operation, or system or plant outages?Reply (2): No. ISTD-5240 restricts snubber testing from beginning earlier than 60 days before a scheduled refueling outage.Question (3): It appears that ISTD is silent in relation to subsequent operational readiness testing requirements for a snubber that has failed operational readiness testing and. after corrective action, is installed at a different location than where the failure occurred.
Is it a requirement of ISTD-5500 for a snubber that has failed operational readiness testing, then after corrective action and subsequently being installed in a different location, to be retested during the next operational readiness testing campaign?Reply (3): No.1-7 ASM .--
