Examples of AMP with Changes as a Result of GALL Revision
XI.M19 – Steam Generator Tube Integrity[edit]
Interim staff guidance (ISG), LR-ISG-2016-01 - “Changes to Aging Management Guidance for Various Steam Generator Components”, includes a revision to XI.M19 in GALL Rev. 2 to address the aging management guidance on loss of material due to boric acid corrosion of steam generator heads and tubesheets. XI.M19 now includes steam generator primary side internal surfaces and dictates that visual inspections of these surfaces should be performed at least every 72 effective full power months or every third refueling outage (whichever results in more frequent inspections). The guidance established by LR-ISG-2016-01 was incorporated into the XI.M19 AMP description in NUREG-2191/2192, Revision 0 for subsequent license renewal.
XI.M41 Buried and Underground Piping and Tanks[edit]
Interim staff guidance (ISG), LR-ISG-2011-03 – “Changes to the Generic Aging Lessons Learned (GALL) Report Revision 2 Aging Management Program XI.M41, ‘Buried and Underground Piping and Tanks’”, revised inspection recommendations for GALL Rev. 2 XI.M41 along with the addition of acceptance criteria for cathodic protection surveys. LR-ISG-2015-01 – “Changes to Buried and Underground Piping and Tank Recommendations”, replaced GALL Rev. 2 AMP Report XI.M41 and associated UFSAR Summary Description in LR-ISG-2011-03. The recommendations provided by the established guidance for XI.M41 modified inspections and testing being performed along with several elements such as the scope and acceptance criteria of XI.M41. Additionally, recommendations related to inspections for selective leaching of buried components were relocated to GALL AMP Report XI.M33. The guidance established by LR-ISG-2011-03 and LR-ISG-2015-01 were incorporated into NUREG 2191/2192, Revision 0 for subsequent license renewal.
XI.M27 Fire Water System[edit]
Interim staff guidance (ISG), LR-ISG-2012-02 – “Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion Under Insulation”, revised GALL Rev. 2 XI.M27 to include revised recommendations to manage the aging effects applicable to fire water system components such as fire water tanks. Appropriate inspections and tests recommended in NFPA 25 were incorporated into XI.M27. LR-ISG-2013-01 – “Aging Management of Loss of Coating or Lining Integrity for Internal Coatings/Linings on In-Scope Piping, Piping Components, Heat Exchangers and Tanks“ revised the GALL Rev. 2 XI.M27 AMP to manage the aging effects associated with fire water tank internal coatings/linings rather than XI.M42 “Internal Coatings/Linings for In-Scope Piping, Piping Components, Heat Exchangers, and Tanks”. However, recommendations from GALL Rev. 2 XI.M42 regarding training, qualification of personnel, “corrective actions”, and “acceptance criteria” for coated fire water storage tank internals enhance XI.M27. The guidance established by LR-ISG-2012-02 and LR-ISG-2013-01 were incorporated into NUREG 2191/2192, Revision 0 for subsequent license renewal.
XI.M36 External Surfaces Monitoring of Mechanical Components[edit]
Interim staff guidance (ISG), LR-ISG-2011-03 – “Changes to the Generic Aging Lessons Learned (GALL) Report Revision 2 Aging Management Program XI.M41, “Buried and Underground Piping and Tanks”", revised GALL Rev. 2 XI.M36 due to an internal conflict between XI.M36 and XI.M41 “Buried and Underground Piping and Tanks” resulting in changes to “scope of program” and “detection of aging effects” of XI.M36. LR-ISG-2012-02 – “Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion Under Insulation”, revised XI.M36 to address detection of aging effects of tightly adhering insulation and to recommend periodic inspections during each 10-year period of the PEO. To address aging management methods for corrosion under insulation, the established guidance revised XI.M36 to recommend that inspection locations should be based on the likelihood of corrosion under insulation occurring. The guidance established by LR-ISG-2011-03 and LR-ISG-2012-02 were incorporated into NUREG 2191/2192, Revision 0 for subsequent license renewal.
XI.M42 – Internal Coatings/Linings for In-Scope Piping, Piping Components, Heat Exchangers, and Tanks[edit]
Interim staff guidance (ISG), LR-ISG-2013-01 – “Aging Management of Loss of Coating or Lining Integrity for Internal Coatings/Linings on In-Scope Piping, Piping Components, Heat Exchangers and Tanks", created GALL AMP Report XI.M42. Some of the already established GALL Rev. 2 AMP Reports can still be used to manage the aging effects for coatings/linings applied to the internal surfaces of components as long as recommendations from XI.M42 are included. However, aging effects associated with fire water tank internal coatings/linings are managed by XI.M27 “Fire Water System”. The guidance established by LR-ISG-2013-01 was incorporated into NUREG 2191/2192, Revision 0 for subsequent license renewal. SLR-ISG-2021-02 – “Updated Aging Management Criteria for Mechanical Portions of Subsequent License Renewal Guidance”, revised XI.M42 in SLR GALL to recommend opportunistic inspections rather than periodic inspections. Environments were also added to the scope of XI.M42.
XI.E6 – Electrical Cable Connections Not Subject to EQ[edit]
NUREG-1801, Revision 2 for license renewal recommends one-time testing prior to PEO for aging effects. NUREG-2191, Revision 0 for subsequent license renewal recommends periodic testing, if warranted, should findings of the initial one-time test find aging effects after performing an evaluation. No impact from interim staff guidance documents.
