| | : 1. Scoce/ Status of Review |
| | ] |
| | The Nuclear Regulatory Commission (NRC) is responsible for the review and disposition of licensee requests relating to inservice inspection requirements contained in the Code of Federal Regulations (CFR) 10 CFR 50.55a, and the American Society of Mechanical Engineers (ASME), |
| | Section XI. . Included within each request, licensees are required to provide both a regulatory basis (by citing the appropriate section of 10 CFR 50.55a), and a technical discussion, to support the request. |
| | This information is used to establish the context for each evaluation. |
| | The staff has reviewed the additional information submitted in the {{letter dated|date=December 9, 1996|text=letter dated December 9, 1996}}. As a result of this review, additional information is required in order to complete the staff's review. |
| | : 2. Additional Information Reauired Based on the review of the December 9, 1996 submittal, the staff has concluded that the following additional information and/or clarification is required to complete the evaluation. |
| | : 1. Under Item A, the licensee provided the following additional paragraph: |
| | "When pressure testing piping systems that contain boron for the purpose of controlling reactivity, the insulation will be removed, on the same frequency as that required for performance of the pressure test, and VT-2 visually examined, without the system at normal operating pressure. Any evidence of leakage will be evaluated in accordance with IWA-5250." |
| | The current position that the NRC has adopted on insulation removal is consistent with Code Case N-533, Alternative Requirements for VT-2 Visual Examination of Class 1 Insulated Pressure Retaining Bolted Connections. Paragraph (2) of this Code case states: "Each refueling outage the insulation shall be removed from the bolted connection, and a VT-2 visual examination shall be performed. The connection is not required to be pressurized. Any evidence of leakage shall be evaluated in accordance with IWA-5250." |
| | Provide the basis for the current position to remove the insulation on a per period basis only. |
| | * l |
| | 'j . i , |
| | i |
| | : 2. Under Item B, the licensee noted an addition to the corrective- J |
| | . measures as follows: |
| | l "In addition, if the leakage is identified at a bolted connection ) |
| | tr.,t is in service and the evaluation supports continued service, 4 toe bolt removal and subsequent VT-3 may be deferred to the next component / system outage of sufficient duration." |
| | j Later editions of the Code have provided an alternative to the |
| | ; removal of all bolting at a leaking connection. The licensee's 1 approach to perform an evaluation of the bolted joint to determine. |
| | }. the need to remove one bolt is considered too generic to be considered acceptable. An. evaluation to determine whether deferral is acceptable is not supported by ISI philosophy. |
| | 3 Therefore the licensee should consider the withdrawal of'this i paragraph. |
| | l 3. For Item C, Request for Relief 12R-12 addresses both Categories |
| | ; C-F-1 and C-F-2. However, the licensee noted that the relief does |
| | ; not apply to ferritic piping (C-F-2) as inspection will continue , |
| | i to be performed on the longitudinal welds in ferritic piping in l accordance with the Code. It is unclear why the licensee has taken exception to ferritic pipe longitudinal welds. Is this request for austenitic piping only? ProYide the basis for the j current position. |

- 1. Scoce/ Status of Review
]
The Nuclear Regulatory Commission (NRC) is responsible for the review and disposition of licensee requests relating to inservice inspection requirements contained in the Code of Federal Regulations (CFR) 10 CFR 50.55a, and the American Society of Mechanical Engineers (ASME),
Section XI. . Included within each request, licensees are required to provide both a regulatory basis (by citing the appropriate section of 10 CFR 50.55a), and a technical discussion, to support the request.
This information is used to establish the context for each evaluation.
The staff has reviewed the additional information submitted in the letter dated December 9, 1996. As a result of this review, additional information is required in order to complete the staff's review.
- 2. Additional Information Reauired Based on the review of the December 9, 1996 submittal, the staff has concluded that the following additional information and/or clarification is required to complete the evaluation.
- 1. Under Item A, the licensee provided the following additional paragraph:
"When pressure testing piping systems that contain boron for the purpose of controlling reactivity, the insulation will be removed, on the same frequency as that required for performance of the pressure test, and VT-2 visually examined, without the system at normal operating pressure. Any evidence of leakage will be evaluated in accordance with IWA-5250."
The current position that the NRC has adopted on insulation removal is consistent with Code Case N-533, Alternative Requirements for VT-2 Visual Examination of Class 1 Insulated Pressure Retaining Bolted Connections. Paragraph (2) of this Code case states: "Each refueling outage the insulation shall be removed from the bolted connection, and a VT-2 visual examination shall be performed. The connection is not required to be pressurized. Any evidence of leakage shall be evaluated in accordance with IWA-5250."
Provide the basis for the current position to remove the insulation on a per period basis only.
'j . i ,
i
- 2. Under Item B, the licensee noted an addition to the corrective- J
. measures as follows:
l "In addition, if the leakage is identified at a bolted connection )
tr.,t is in service and the evaluation supports continued service, 4 toe bolt removal and subsequent VT-3 may be deferred to the next component / system outage of sufficient duration."
j Later editions of the Code have provided an alternative to the
- removal of all bolting at a leaking connection. The licensee's 1 approach to perform an evaluation of the bolted joint to determine.
}. the need to remove one bolt is considered too generic to be considered acceptable. An. evaluation to determine whether deferral is acceptable is not supported by ISI philosophy.
3 Therefore the licensee should consider the withdrawal of'this i paragraph.
l 3. For Item C, Request for Relief 12R-12 addresses both Categories
- C-F-1 and C-F-2. However, the licensee noted that the relief does
- not apply to ferritic piping (C-F-2) as inspection will continue ,
i to be performed on the longitudinal welds in ferritic piping in l accordance with the Code. It is unclear why the licensee has taken exception to ferritic pipe longitudinal welds. Is this request for austenitic piping only? ProYide the basis for the j current position.
