and provide certain additional information to be used for an independent determination of conformance to these guidelines.
IMEC responded on July 31, 1981[4].U I J(l Franklin Research Center A Oivisen d%bc Franklin Insecure TER C5257"68 2 o EVALUATION AND RECOMMENDATIONS PRC's evaluation of load handling at D.C.Cook Units 1 and 2 is divided into two categories.
ese ca e Th categories deal separately with the general-guidelines o xc e f Art'5 1.1 and the recommended interim pr otection measures of Article 5.3 of NUREG-0612.
Applicable guidelines aze referenced in each category.PRC'onclusion and recommendations ar p e rovided in the summary s c for each guideline.
2.1 GENERAL GUIDELINES The NRC has established seven general guidelin es which must.be met in order to provi e e'd th defense-in-depth approach for the handlin of heavy g lowin criteria from Section 5.1.1 loads.These guidelines consist of the fol owi g of NUREG-0612:
o Guideline 1" o Guideline 2 o Guideline 3 o Guideline 4 o Guidel'ine 5 o Guideline 6 o Guideline 7 Safe Load Paths Load Handling Procedures Crane Operator Training Special Lifting Devices Lifting Devices (Not Specially Designed)Cranes (Inspection, Testing, and Maintenance)

TER C5257-68 o auxiliary building crane o new and spent fuel handling crane o polar cranes (one per unit)o manipulator cranes (one per unit)~2.1.2 Safe Load Paths Guideline 1, NUREG-0612 Article 5.1.1(1)"Safe load paths should be defined for the movement of heavy loads to minimize the potential for heavy loads, if dropped, to impact irradiated fuel in the reactor vessel and in the spent fuel pool, or to impact safe shutdown equipment.
The path should follow, to the extent practical, structural floor members, beams, etc>such that if the load is droppedr the structure is more likely to withstand the impact.These load paths should be defined in procedures, shown.on equipment layout drawings, and clearly marked on the floor in the area where the load, is'to be handled.Deviations from defined load paths should require written alternative procedures approved by the plant safety review committee." a.Summa of Licensee Statements and Conclusions The Licensee stated that defined load paths are being imposed on the movement oE heavy loads in the auxiliary building in the vicinity of the new fuel storage area.Heavy loads listed, in Table 3.1, with the exception of radiation protection shields, are moved at a height of 7 Eeet from the floor and as close as possible to the south wall.The auxiliary building crane, unloaded, is moved through the restricted area with the carriage as close as possible to themouth wall.The Licensee stated that special procedures for handling heavy loads in the auxiliary building will be written.to cover the above restiictions and the load path will be indicated'n the floor.Heavy loads in the containment building are handled by the polar crane.A procedure will be developed to'define the load path Eor the missile shields and cavity bulkhead sections.b..PRC Evaluation The Licensee's response provides insufficient information for FRC to deter-mine if safe load paths have been developed for the individual heavy loads handled by the polar cranes.A review of the plant arrangement drawings showing!Ill Franklin Research Center h Otkskn ot Thc FrenkSn Insecure TER-C5257-68 the safe load paths in the auxiliary building indicates that the load paths are defined by excluding specific areas<rather than by defining individual safe load paths for each heavy load handled in the vicinity of irradiated fuel or safe shutdown equipment.
Insufficient information was provided by the Licensee to allow PRC to determine if heavy loads are handled in accordance with the t following criteria: l.load paths have been selected to follow, to the extent practical, structural floor members 2.load paths are clearly marked on the floor 3.load paths are defined in the procedures 4.deviations from established load paths require written alternatives approved by the plant safety review committee 5.load paths are shown on equipment layout drawings.c.FRC Conclusions and Recommendations IMEC does not comply with Guideline 1.The Licensee should develop safe load paths for individual heavy loads handled in the vicinity of irradiated fuel or safe shutdown equipment.
The Licensee should ensure that the safe load paths comply with the criteria of this guideline (i.e., load paths are defined in procedures and drawings, follow structural members, are clearly marked, and deviations are strictly controlled)
.2.1.3 Load Handlin Pro'cedures Guideline 2 NUREG-0612, Article 5.1.1{2"Procedures should be developed to cover load handling operations for heavy loads that are or could be handled over or in proximity to irradiated fuel or safe shutdown equipment.
At a minimum, procedures should cover handling of those loads.listed in Table 3-1 of NJREG-0612.
These procedures should includes identification of required equipmentg inspections and acceptance criteria required before movement of load;the steps and proper sequence to be followed in handling the load;defining the safe path;and other special precautions."~IlIL Franklin Research Center h Olvtsen el The Frauen lmete
TER-C5 257-68 a.Summa of Licensee Statements and Conclusions Procedures are in effect to govern the movement of heavy loads that are or could be handled near irradiated fuel or safe shutdown equipment.
The procedures include identification of required equipment<
inspection and acceptance criteria required before movement of the load, and other special'procedures.
Procedures for the spent fuel shipping cask will be developed when required.Procedures for handling the missile shields and bulkhead walls including the designated load paths will be prepared.b.FRC Evaluation ZMEC partially satisfies the criteria of'uideline 2;however, the information supplied was not sufficient for FRC to determine (1)if the procedures include the steps and proper sequence to be followed in handling the load and (2)if safe load paths have been defined.FRC does not find'acceptable for safe load paths and procedures not to have been established for the spent fuel shipping cask.Since this review by FRC constitutes the only comprehensive evaluation of load handling'practices at D.C.Cook Units 1 and 2, all issues should be resolved either by compliance with the guideline or<if in the case of nonmompliance<
by instituting the recommended corrective actions within a reasonable period of time so that no items are deferred to a future unspecified date.Therefore<
the Licensee should develop the" necessary safe load paths for the spent fuel shipping cask in anticipation of subsequent load handling operations.
c.FRC Conclusions.and Recommendations D.C.Cook Units 1 and 2 partially comply with Guideline 2.Xn order to fully comply, IMEC should revise heavy load handling procedures to ensure that (1)safe load paths are defined and (2)the steps and proper sequence to be followed in handling the load are included.The Licensee should develop, procedures for handling the spent fuel shipping cask<missile shields<and cavity bulkhead sections.l)ll Franklin Research Center A~of~FranCn Quatre

c.FRC Conclusions and Recommendations D.C.Cook Units 1 and 2 comply with Guideline 3.Training and'ualifica-tion programs developed by D.C.Cook Units 1 and 2 comply with ANSI B30.2.The Licensee should srerify that suitable programs to monitor or ensure proper operator conduct have been implemented.
These programs may consist of review of operator conduct during training and qualification, surveillance or monitoring of operators during actual load handling by.plant safety or quality l assurance personnel, or supervision of load handling by selected senior crane'r plant supervisors.
2.1.5 S ecial Liftin Devices Guideline 4 NUREG-0612, Article 5-1.1 4)"Special lifting devices should satisfy the guidelines of ANSI N14.6-1978,'Standard for Special Lifting Devices for Shipping Containers Neighing 10,000 Pounds (4500 kg)or More for Nuclear Materials'6l.

TER-C5257-68 areas as defined above.For operating plants certain inspections and load tests may be accepted in lieu of certain material requirements in the standard.In addition, the stress design factor stated in Section 3.2.1.1 of ANSI N14.6 should be based on the combined maximum static and dynamic loads that could be imparted on the handling device based on characteristics of the crane which will be used.This is in.lieu of the guideline in Section 3.2.1.1 of ANSI N14.6 which bases the st:ress design factor on only the weight (st:atic load)of the load and of the interven-ing components of the special handling device." a.Summa of Licensee Statements and Conclusions The Licensee stated that the requirements for special lifting devices<as set forth in ANSI N14.6-1978,"Standards for Special Lifting Devices for Shipping Containers Weighing 10,000 Pounds or More for Nuclear Materials," are met in the following procedures:
o load monitoring device verification instructions o manipulator crane load test o auxiliary building crane interlock verification fuel handling o shipment of reactor vessel material surveillance capsule using SWRI'ask and equipment.
b.FRC Evaluation The Licensee has developed a set of procedures which meet the criteria of Section 5{Acceptance Testing and Assurance of Continued Compl'iance) of ANSI N14.6>>1978.
However, the Licensee did not discuss the criteria of Section 3{Design), Section 4 (Fabrication), or Section 6 (Special Lifting Devices for Critical Loads)of ANSI N14.6 or the recuirements of this guideline.
c.FRC Conclusions and Recommendations D.C.Cook Units 1 and 2 partially comply with Guideline 4.The Licensee should evaluate those special lifting devices in use to determine compliance with Sections 3, 4, and 6 of ANSI N14.6-1978 prior to their next use.llll Franklin Research Center A DMslon d The FranlCn InsdoAe TER-C5257 68 2.1.6 Liftin Devices (Not S eciall Desi ned)Guideline 5, NUREG-0612 Article 5.1.1(5)"Lifting devices that are not specially designed should be installed and used in accordance with the guidelines of ANSI B30.9-1971,'Slings'7].
However, in selecting the proper sling, the load used should be the sum of the static and maximum dynamic load.The rating identified on the sling should be in terms of the'static load'hich produces the maximum static and dynamic load.Where this restricts slings to use on only certain cranes, the slings should be clearly marked as to the cranes with which they may be used." a.Summa of Licensee Statements and Conclusions The Licensee stated: "Lifting devices that are not specially designed follow the guidelines set forth in Handbook for Ri ers by W.G.Newberry, revised edition 1977." b.PRC Evaluation IMEC did.not provide sufficient information for FRC to determine if the'I lifting devices not specially designed are installed and used in accordance with ANSI B30.9-1971, or if plant procedures ensure proper sling selection, rating, and identification.
c.FRC Conclusions and Recommendations A conclusion with respect to Guideline 5 must be deferred.INC should review all handling devices, identify those which are not,specially designed and are use'd in the vicinity of irradiated fuel or safe shutdown equipment, and ensure that these devices conform to the, criteria of ANSI B30.9<<1971 before they are next used.INEC should also ensure the following:
1.sling selection is based upon the sum of static and maximum dynamic loads 2.slings are marked with the"static load" which produces the maximum static and dynamic loads 3.slings restricted to use with only certain cranes are clearly marked to so indicate.(II Franklin Research Center A basion et Tbe FrankSn Insstutt<<9>>

Guideline 6 NUREG<<0612 Article 5.1.1(6"The crane should be inspected, tested>and maintained in accordance with Chapter 2-2 of ANSI B30.2-1976,'Overhead and Gantry Cranes,'ith the exception that tests and inspections should be performed prior to use where it is not practical to meet the frequencies of ANSI B30.2 for periodic inspection and test, or where frequency of crane use is less than the specified inspection and test frequency (e.g., the polar crane inside a PNR containment may only be used every 12 to 18 months during refueling operations, and is generally not accessible during power operation.
ANSI B30.2, however, calls for certain inspections to be performed daily or monthly.For such cranes having limited usage, the inspections, test, and maintenance should be performed prior to their use)." a.Summa of Licensee Statements and Conclusions The cranes at D.C.Cook Units.1 and 2 are inspected, tested, and maintained in accordance with Chapter 2.-2 of ANSI.B30.2-1976.
b.FRC Evaluation The Licensee has committed to crane inspection, testing, and maintenance in accordance with ANSI B30.2-1976.
c.FRC Conclusion IMEC complies with the criteria of Guideline 6.2.1.8 Crane.Desi n Guideline 7 NUREG-0612 Article 5.1.1 7"The crane should be designed to meet the applicable criteria and guidelines of Chapter 2-1 of ANSI B30.2<<1976,'Overhead and Gantry Cranes<'nd of CMAA-70r'Specifications for Electric Overhead Traveling Cranes'8].
An alternative to a specification in ANSI B30.2 or CMAA-70 may be accepted in lieu of specific compliance if the intent of the specification is satisfied." a.Summa of Licensee Statements and Conclusions The Licensee stated that the cranes at-the D.C.Cook Units were built by Hhiting Corporation in accordance with Electric Overhead.Crane Institute!ill FrenM(n Resenrch Center h Givtston et The Frsnkhn lnsCute>>10-

SUMMARY
Measures have been implemented at Indiana and Michigan Electric Company s I Donald C.Cook Units 1 and 2 which satisfy and comply, to some extent<with NRC general guidelines and interim protection measures identified in NUREG-0612.In particular, implementation of ANSI B30.2-1976 for crane operator training.and qualification; crane testing<inspectionr and maintenance; and implementation of technical specifications to prohibit movement of heavy loads over the spent fuel pool satisfy the criteria of the NRC guidelines.
Action is required by the Licensee to satisfy NRC criteria for safe load paths, procedures, special lifting devices, lifting devices not specially designed, and special attent'ion for heavy loads handled over the core.III)Franklin Research Center A Decision of The Fzanl4n Iruome-18
