I Hope Creek Generating Station, Unit 1 Preservice Examination Limitations Final Report

1. Introduction Southwest Research Institute (SwRI) was contracted by Public Service ,

Electric and Gas Company (PSE&G) to perform the preservice examination '

(PSI) of the Hope Creek Generating Station (HCOS). Examinations were performed in accordance with the PSI Plan during the period of September 1983 through October 1985. During this period, any i examination area coverage limitations which were encountered were recorded on data record sheets. This report summarizes and documents j the examination area limitations which limit Code coverage based on

! the examination requirements of ASNE Section II,1977 Edition with 1 Addenda through the Summer 1978 and NRC Regulatory Guide 1.150.

2. Discussion PSE&G assisted by SwRI, focused significant attention to minimizing

examination area limitations prior to, and during, the PSI at HOGS.

. As a result of these preparations, minimal examination ares limitations were encountered. An SwRI Access Engineering Program was implemented during plant design and construction to maximize examination area access. This program evaluated access and provided l

design guidance to PSE&G and Bechtel Corporation for piping, components, and the reactor pressure vessel (RPV). Examples of design criteria to facilitate examination included weld surface profiling, minimum access clearances for piping and components, and counterboring l

to minimize inside surface indication resolution questions. The Access Engineering Program also designed track placement on the RPY to maximize the vessel mechanized examination coverage. As a result, all i l vessel velds received at least partial volumetric coverage. l During the performance of the PSI onsite activities, PSE&G was notified of the examination area limitations that were encountered.

Each limitation was evaluated by PSE&G to determine alternative approaches which could afford a'more thorough coverage of the Code-specified examination volume or area.

SwRI var requested to provide expertise in making recommendations of feasible alternatives to the planned exaninations. This process was I

expanded to include consideration of future Codes and ISI conditions which may make alternative examination techniques more or less j valuable as determined on a case-by-case basis. The result of this ongoing process was the completion of the PSI with the minimization of j limitations to the examinatica coverage as required by the Code. l

}

Special examination technique developments, supported by PSE&G, 3 maximized examination coverage during the course of the PSI. These include a UT technique for veld examination through corrosion resistant clad (CRC) piping in the Reactor Recirculation System. This process involved basic research centered on ultrasonic transducer development and testing on mockups which were a result of PSE&G j efforts to ensure similarity to the "as-built" condition of the CRC i velds at HCGS. An examination technique for the RPY closure stud was

! also developed to provide the examination coverage specified in the i Code Case N307-1. PSE&G and SwRI also agreed to the utilization of a j newly-introduced, automated ultrasonic examination system (AMDATA)  :

which provided additional capability for minimizing limitations l J

attributable to veld joint configurations. Further benefits of the ANDATA system included comprehensive recording of the test data for future comparison during ISI conditions. These programs attest to the f act that PSE&G and SvRI performed the PSI at HCGS with full  ;

l consideration of the factors that could maximize the effectiveness as j determined by evaluation of the ncet minute details.

Even with a program of such proportions, Ibaitations of two basic types were encountered. Even with extensive examination procedure I development, generic lhaitations were encountered inherent to i examination areas and state-of-the-art examination techniques.

Inherent to the ultrasonic examinations where a full volumetric coverage is required from the entry surface to the opposite surface is the limitation at the near surface due to sound beam entry noise. The second type of ILaitation is a result of scanning limitations due to

component configuration or physical restrictions. For example, a limitation to scanning due to an adjacent bracket or nozzle would

. prohibit the placement of the scanning device or transducer in a l particular area and a scanning limitation would result. For

examination areas where track placement was impractical and where l radiation exposure is considered to be acceptable for examiners during

' subsequent ISIS, the mechanized examinations were supplemented with manual examination techniques.

3. Limitation Summary Tables j The following tables provide details on the limitations which were encountered during the PSI at HCGS. The areas are listed in the order

, found in the PSI Plan. The information in the tables is supplemented 4

with figures and sketches as required. Table 1 of this report

provides informat' ion as follows

i The first column, " Class / Category / Item No. ," identifies the ASME Code class, category, and item number for the specific examination area identified in the second column. Column 2 provides the examination area description and the examination requirement. The

third column, " Identification of Limitation" identifies the type of limitation and extent. The following should be noted

1) Examination volume limitations may be encountered, even

when scanning of the complete weld length is possible.

2) In some cases, physical scanning limitations do not limit I

beam components from obtaining coverage beyond the physical l ILaitations. This is possible when the besa component can be directed

to pass under the physical ILaitations, thus increasing total l examination volume coverage.

l 3) Pressure vessel lhaitations have been identified by the

, percent of weld length accessible for scanning and the percent of the l Code-required volume examined.

I

4) For piping, limitations are identified by their physical location or "L" dimension.

1 The fourth column identifies the " Basis For Relief" to include 4

specific information with respect to the type of interference.

The fifth column, " Fabrication NDE," describes the fabrication / con-i struction NDE that was performed to satisfy the requirements of ASME Section III.

The " Remarks" column provides clarification of actual Code examination area limitations and information specific to later Code ,

editions which may change the coverage requirements for subsequent incervice examinations. Where the Code specifies more than one method end complete coverage is obtained, is also noted under " Remarks".

j Table 2 provides a detailed listing of the percentage of volume

]' coverage in compliance with paragraph 7 of Regulatory Guide 1.150, Revision 1, for reactor vessel welds. The information provided includes percent of coverage for each angle used, as well as, the cumulative coverage. The cumulative coverage is defined as the n2ximum percent of coverage achieved with at least one angle-beam component.

The attached figures present a pictorial representation of the examination area coverage. Figures are presented for the vessel welds and nozzle inner radii.

4. Conclusion i

The PSI program at HCGS was performed with full consideration of the limitations and capabilities of the nondestructive examination methods available. PSE&G and SwRI cooperated fully in an effort to ensure that the PSI was performed with the maxi == coverage feasible. This j report is the documentation of the areas in which limitations were i

present that could not be eliminated through the combined efforts of

] PSE&G and Sw1I.
