INTRODUCTION SIXTY-DAY RESPONSE TO Palisades Sixty-Day Re~ponse NRC IE Bulletin 80-11

  • .;rune 19 8 0 NRC IE BULLETIN 80-11 This report has* been prepared in response to NRC IE Bulletin 80-11, dated May 8, 1980.

It has been prepared b~ Bechtel Power Corporation, Ann Arbor, Michigan, for Consumers Power Company's (CPCo's) Palisades Nuclear Plant.

This report submits information requested in Items 1, 2a, and 3 of NRC IE Bulletin 80-11, dated May 8, 1980.

A total of 73 potentially safety-related masonry wall segments

  • have been identified.

A masonry wall may be composed of several segments.

For purposes of identification, total count, and re-evaluation, a masonry wall segment has been defined as a uniform, straight run of wall between support or terminal points.

2.

IDENTIFICATION OF SAFETY-RELATED MASONRY WALLS AND THEIR SYSTEMS

. Safety-related systems, components, and structures have been generally defined as those listed on the Palisades plant Q list.

The boundaries of seismic analyses per-formed in the.course of responding to NRC IE Bulletin 79-14 have also been used where applicable in the determination of whether an item is safety related.

CPCo has designated potentially safety-related masonry walls at the Palisades plant.

CPCo has also performed a search for potentially safety-related masonry walls in safety-related areas not shown on the design drawings.

Safety-related systems which are either attached to, penetrate, or are in proximity to potentially safety-related masonry walls are listed in Appendix A.

For purposes of identification, proximity is defined as within an arc length equal to a masonry wall height from the base of each face of the masonry wall extending to the floor.

Furthermore, in plan view, proximity is defined by lines normal to the masonry wall extending from the ends of the masonry wall.

Proximity does not extend beyond compartments.

l'

Palisad~s Sixty-Day Response NRC IE Bulletin 80-11 June 1980 The potentially safety-related masonry walls do not generally support a structurally significant amount of e~~ipment.

A.

WALL INSPECTION Identification of potentially safety-related masonry walls started in May 1980.

This included a review of design drawings, the plant Q list, and a walkdown of the plant.

A team started a detailed inspection of masonry walls on June 3, 1980.

The team is collecting, verifying, and recording information regarding the as~built condition of existing masonry walls and structurally significant attachments.

The presence of safety-related items in proximity to or attached to the masonry walls is also documented.

In some instances, ALARA' considerations require that time spent near a masonry wall be minimized and that the inspection be limited to visual observations from some distance away from the masonry wall.

These observations were compared with-the design drawings.

Confidence was established that the data obtained are adequate for masonry wall re-evaluation, and it is not intended that a.further inspection be made of these masonry walls.

B.

W1'.LL PLANS WITH IDENTIFICATION NUMBERS Plans have been prepared to locate and number masonry walls (Appendix A).

Only the masonry walls which were designated as potentially safety related are further discussed and documented in this report.

3.

PRIORITIZED PROGRAM 0

A.

PRIORITIZED ORDER OF REVIEW Safety-related masonry walls will be re-evaluated using the following order of priority:

1)

Masonry _Walls Supporting Safety-Related Equip-ment with Estimated Design Loadings Greater than

  • 100. Pounds, or Safety-Related Piping 2-1/2 Inches in Diameter or Greater
2)

Masonry Walls Supporting Other Safety-Related Items

3)

Masonry Walls with Safety-Related Equipment in Proximity 2

B.

COMPLETION SCHEDULE Palisades Sixty-Day Response NRC IE Bulletin 80-11 June 1980 It is anticipated that the re-evaluation of safety-related masonry walls to acceptance criteria prepared by Bechtel Power Corporation will be completed by November 4, 1980.

4.

RE-EVALUATION CRITERIA A.

  • GENERAL The Palisades plant Final Safety Analysis Report (FSAR) does not specifically address masonry walls.

Loadings will be defined from the FSAR and existing analyses for Seismic Category I structures.

Load combinations will contain the applicable elements specified in the FSAR.

  • B.

ANALYSIS Analyses will be.performed using standard calculation procedures to determine the structural adequacy of the safety-related masonry walls.

Masonry walls are con-*

sidered to be isotropic, elastic material.

Plate or beam theory will be used to satisfy static equilibrium under all loading conditions.

Cracked and/or uncracked section analyses will be performed, as applicable, to determine the.stresses in the masonry and in the reinforcing steel.

Highly stressed areas will be checked against the corresponding allowable stresses.

c.

JUSTIFICATION OF RE-EVALUATION CRITERIA Justification for the re-evaluation criteria will be submitted with the re-evaluation report within 180 days of the date of the bulletin received..

Justifications will be based on refererice to existing codes and estab-1 ished standards of practice related to concrete and masonry design.

It is anticipated that such justification will be considered appropriate, and that a test program will not be necessary, except as required to determine project unique structural properties and any other properties for which data are not available or cannot otherwise be determined.

Palisades Nuclear Plant, Final Safety Analysis Report, Docket 50-255 3

Palisades Sixty-Day Response NRC IE Bulletin S0-11 June 1980 APPENDIX A WALL PLANS AND INFORMATION TABLES *FOR POTENTIALLY SAFETY-RELATED MASONRY WALLS The attached identifies safety-related equipment and systems associated with safety-related masonry walls.

This listing is subject to revision.

The listing of systems associated with certain items is* intended to reflect the primary system or systems associated with the par-ticular item.

For certain items (e.g., cable tray), a large list of systems would be required to completely define safety-related equipment.

For these items, the term "various" is used for systems

.in the attached tables.

These masonry walls do not generally support a structurally significant amount of nonsafety-related equipment.

Therefore, attached nonsafety-related equipment and systems are not listed.

Attached nonsafety-related equipment will be considered in the re-evaluation of. these masonry walls.

The masonry wall number is the drawing number followed by a decimal, followed by the wall number indicated on the drawing.
