OUTLINE FOR NUREG REPORT

TASK A-36

CONTROL OF HEAVY LOADS NEAR SPENT FUEL

1. INTRODUCTION

1.1 BACKGROUND

(Def. of Heavy Load, potential consequences of accidental

load drop [ release of radioactive material, criticality,

damage to systems required for safe shutdown or continued

decay heat removal], extent considered in previous licensing

actions, and purpose for task).

1.2 DEFINITIONS

1.3 A-36 REVIEW PROCESS

(Brief dc;criptic.. of review process including: initiala

review, generic letter to licensees, information submitted,

survey of information, group discussion of various scenarios,

development of fault trees, analysis of available data, develop-

ment of guidelines, NUREG report).

1.4 SUMMARY OF RECOMMENDATIONS

(An executive type sumary of guidelines and recommendations).

2. SURVEY OF LICENSEE INFORMATION

2.1 HEAVY LOADS

(A discussion of the various heavy loads, and their frequency of

movement, that may be moved over or near spent fuel in the

reactor vessel or spent fuel pool).

2.2 PRESENT PROTECTION

(A description of the present protection provided that prevents,

or mitigates the consequences of, accidental load drops in-

cluding discussions of the following:)1728 299

2.2.1 Technical Specifications

2.2.2 Procedures

2.2.3 Crane Designs

2.2.4 Other Design Features

2.2.5 Crane Operator Training

2.3 PREVIOUS ANALYSES

( A discussion of various analyses performed previously by

licensees or their consultants related to heavy load drop

accidents).

3. REVIEW 0F HISTORICAL DATA

(A discussion of the available historical data related to heavy load

handling at nuclear facilities and crane operations at non-nuclear

facilities. Will include a discussion of the conclusions thatmay be drawn from this data. Provide summary of data in Appendix A).

4. GUIDELINES

GUIDELINES FOR CONTROL 0F HEAVY LOADS4.1 _(Lead-in should provide background, such as: the objectives

of the guidelines, that various alternatives are provided to

meet the objectives, and that fault trees were developed and used

as discussed in Section 4.3 to evaluate the adequacy of the

guidelines).

4.1.5 Other Areas

4.1.6 Single Failure Proof Cranes and Lifting Devices

4.2 BASES FOR GUIDELINES

(A discussion which provides the staff basis for the guidelines

including use of fault trees, historical data, and information

from licensees. Should sumarize conclusions that may be

drawn from the fault trees).

5. RECOMMENDATIONS

5.1 IMPLEMENTATION OF GUIDELINES - OPERATING PLANTS

(Recommend a program for implementing guidelines at operating

plants, reference draft generic letter, discuss impact of

implementation on operating plants, and discuss manpower,

technical assistance, and schedule for NRC to carry out a pro-

gram to implement the guidelines) .

5.2 INTERIM ACTIONS ~[ hadww(Discuss imediate actions required until guidelines are

implemented and basis for operation with only these actions

and existing measures).

5.3 CHANGES TO S.R.P's and R.G. 's

(Generalize recommended changes to SRP's and RG's to incorporate

guidelines not almady included).

APPENDICES'

Appendix A - Crane Historical Data

1. Navy

2. OSHA

3. NASA

4. LER

Will provide a data summary for each of these data sources.

Appendix B - Fault Trees

Will provide the fault trees developed related to handling of heavy loads,

development of probabilities for various events and sumary of probability

estimates for various cut-sets.

Appendix C - Modification of Existing Cranes

( A discussion of the typical modifications that may have to be made if

upgrading to intent of NUREG - 0554, feasibility of making such modifications,

and availability of equipment for these modifications. Will also include,

if possible, an implementation section identifying elements of NUREG 0554

that must be met in upgrading, and those elements where alternative

compensating actions may be taken in lieu of specific compliance. May

also indicate typical alternative actions that may be acceptable.
