Safety-Related Pipe Supports and Restraint Systems (50090) (Unit 1)

Observation of Work and Work Activities

-

The inspector observed inspection of the four trechanical snubbers listed below prior to installation and torquing of bolts to the support plates.

The snubbers were checked for smoothness of shaft travel by simulating normal operation by pulling and pushing the snubber shaft; the inspector also simulated unit activation by sudden movement.

It was also noted that there was no evidence of deterioration or noticeable corrosion and that the support plates and connecting joints were not bent, deformed, or loose.

The inspector also inspected the snubber components for traceability by heat numbers, serial numbers or markings, the snubbers' pins, studs, bolts, and nuts.

Review of Readiness Review Module 11, Pipe Stress and Supports (Unit 1)

a.

General

This inspection report documents Region II's initial site inspection relative to the evaluation of GPC's Readiness Review Module 11, Pipe Stress and Supports.

The inspection was conducted to aid in determining whether Module 11 provided an acceptable basis for its reported conclusion, concerning Unit 1 and common plant facilities of i

the Vogtle Electric Generating Plant (VEGP), that the design and

'

construction programs, and processes associated with. pipe stress analysis and pipe supports within the scope identified within this module were in accordance with applicable licensing commitments.

!

Readiness Review Module 11 is one portion (module) of a many part review being conducted by GPC to aid in assuring that VEGP Unit 1 and

Boundaries of Module 11

<

!

The inspector completed the initial examination of the. boundaries

>

I associated with Module 11 as indicated within Section 1.0 of the.

,

j report.

The objective during this examination was to 'get a clear understanding of the commitments, activities and responsibilities in Module 11 and to aid in determination of the extent to which important

,

i activities and commitments have been included and treated in the GPC

'

review.

l-c.

Section 1.0, Introduction

i Section 1.0 of the report indicated that Module 11 covered design and construction commitments and activities for pipe stress analysis and j

pipe supports for Unit 1 and common plant facilities.

This report addressed the safety-related mechanical systems classified as American

!

)

Society of Mechanical Engineers (ASME),Section III, Class 1, 2, 3, and

l nonsafety-related systems supported to Seismic Category I requirements i

for protection of safety-related components. Also, the piping system I

final design verification program and construction of pipe - whip j

restraints was addressed. For simplicity, this module does not. include

the Westinghouse responsibility for the complete Class 1 stress

[

,

l-analysis for four-inch and larger piping and for-the fatigue analysis

'

}

for all other Class 1 piping.

j d.

Section 2.0, Organizational and Division of Responsibility i

Section 2.0 provides details of the design organization and field

,

f construction organization at. Plant Vogtle.

This includes a brief

!

description of the organization, responsibilities, and interface

relationships between GPC, BPC, PPP, 'and SCS for design, procurement,

)

and construction activities related to pipe supports, f

The inspector completed the initial examination of Section-2.0.

The

.

'

objective during this examination was verification of general content

!

and accuracy. No significant errors or omissions were identified.

e.

Section 3.0, Commitments

Section 3.0 provides the commitments GPC identified for Module 11 and

,

the verification of their implementation. -Subsections 3.1 through 3.3

addition to providing a listing of the commitments identified, t

Subsection 3.4 provides an identification and :a determination as to

_

whether implementation of the commitment was-a design organization

responsibility, a construction organization responsibility or-the responsibility of both. The Subsection 3.5 matrix includes, _ for each

commitment, an identification of. design and/or -construction documents

[

The inspector completed an initial review of the material presented in

,

I the Module 11 Subsections 3.4 and 3.5 matrices to determine whether the t

Readiness Review had -satisfactorily identified commitments for the '

module and if it had satisfactorily determined their inclusion in j

implementing documents.

i

!

-

The inspector began his evaluation by examination of VEGP Final Safety Analysis Report (FSAR) and NRC Inspection and Enforcement Bulletins

,

(IEBs) to identify safety-related commitments'that appeared to apply to

Module 11. A comparison with the FSAR Chapters 3 and 6 and Module 11

,

'

'

commitments and implementation matrices was made to determine if the

'

Readiness Review group had identified commitments from the FSAR and for the IEB responses that represented the commitment material on the

<

inspector's independently selected sample. 'A total of~50 (over 50%)

)

t

commitments were chosen for NRC verification of implementation. The

{

inspector identified 19 questions that-required clarification by the

!

!

Readiness Review group to ascertain ' the exclusion, inclusion or

j clarification of the commitments.

Violation of project procedures with no safety concerns.

Section 6.0 is divided into two subsections, Subsection 6.1, which describes design program verification and Subsection 6.2, which describes construction program verification.

(1) Subsection 6.1, Design Program Verification, as described in the Module 11 report, Readiness Review verification of the design program was performed by a design RR team (RRT) consisting of five

,

engineers, experienced in power plant design engineering.

The verification was intended to insure, through sampling, that the design process for pipe stress and supports has functioned effectively, and had resulted in proper implementation of licensing commitments in design documents.

The module report describes the design program verification as having been performed in two parts.

Part I was the verification of licensee commitments documented in Module 11 report Section 3.4 to identi fy specific project commitments regarding pipe stress and support design and the review and selection of specific commitments for their i

implementation into pipe stress and pipe support second-level design documents.

Part II was the verification of the programmatic aspects of design as well as an assessment that commitments and technical requirements were conducted in accordance with project procedures and Quality Assurance (QA) requirements (i.e., ANSI N45.2.11).

!

(2) Subsection 6.2, Construction Program Verification as described in Module 11 report, the Readiness Review verification was performed by a Construction RRT consisting of five personnel certified to

Level.II capabilities in accordance with ANSI N45.2.6, and

experienced in nuclear construction.

It was intended to ensure, through sampling, that the construction process for the completed pipe supports and related installation activities performed by PPP

>

had been adequately controlled and had resulted in proper implementation of licensing commitments.

The inspector met with the Readiness Review management and set up the proposed inspection that would be necessary to assess the

!

design and construction sections of this module.

The Readiness Review group was given a list of 11 piping isometrics of which seven (16%) isometrics were evaluated by the RRT in the design t

assessment, and two (25%) isometrics were evaluated by the RRT in

the construction assessment. The other two isometrics are the NRC sample outside sampling covering two additional systems.

The Readiness Review management has agreed to assemble all the documentation listed below to facilitate the NRC review of all the documentation related to the isometrics chosen and to arrange for the proper QC personnel to be familiar with the areas chosen and assist in the construction verification assessment.
