The staff's conclusion from this evaluation was that existing measures to control the handling of heavy loads at operating plants, although providing protection from certain potential problems, do not adequately cover the major causes of load-handling accidents and should be upgraded.
In order to upgrade measures for the control of heavy loads, the staff developed a series of guidelines designed to achieve a two-phase objective using an accepted approach'or pro'tection philosophy.
The first portion of the objective, achieved through a set oi general guidelines identified in NUREG-0612, Article 5.l.l, is to ensure that all load-handling systems at nuclear power plants are designed and operated such that their probability of failure is uniformly small and appropri'ate for the'critical tasks in which they are employed.The second portion of the staff's objective, achieved through guidelines identified in NUREG-0612, Articles 5.1.2 through 5.1.5, is to ensure that, for load-handling systems in areas where their failure might result in significant consequences, either (a)featu>es are provided, in, addi.tion to those required for all load-handli-ng.systems,.to ensure that the potential for a load drop is extremely small'e.g., a single-failure-proof crane)or (b)conservative evaluat>ons of load-handling accidents indicate that, the potential consequences of any load drop are acceptably small.Acceptability of accident consequences is quantified in HUREG-0612 into four accident analysis eva'luation.criteria.
~~The approach used to develop the staff guidelines for minimizing the potential for a load drop was based on defense in depth and is summarized as fo'ilows: o Provide sufficient opera.~or training., handl'ing system design, load"handling instructions, and equipment inspection to assure reliable operation of the handling system o Define safe load travel paths through procedures and operator training so that, to the extent practical, heavy loads are not carried over or near irradiated fuel or safe shutdown equipment o Provide mechanical stops or electrical interlocks to prevent movement of.,heavy leads.over irradfahed fuel.or i.n proximity to equipment associated with redundant shutdown paths.
Staff guidelines resulting from the foregoing are tabulated in Section 6 of NUREG-0612.
1.3 Plant-Specific Back round 5 I~I~)r On December 22, 1980, the NRC issued a letter I'3]to Pennsylvania Power&Light Company, the applicant for Susquehanna Steam Electric Station, Unit 2 requesting that the applicant review provisions for handling and control of heavy loads at SSES No.2, evaluate these provisions with respect to the guidelines of NUREG-0612, and provide certain additional information to be used for an independent determination of conformance to these guidelines.
On July 22, 1983, Pennsylvania Power.&.Light Company~provided the initial e.esponse I 4]to this request.
2.EVALUATiON ANO RECOMMENOATIONS 2.1'Over vi ew The following sections summarize Pennsylvania Power&Light Company's review of heavy load handling at Susquehanna Steam Electric Station, Unit 2 accompanied by EG&G's evaluation, conclusions, arid recommendations to the applicant for bringing the facilities more completely into compliance with the intent of NUREG-0612.
Pennsylvania Power&Light Company'review of the facilities does not differentiate between the two units so it is assumed that both units are of identical design.The applicant has indicated the weight of a heavy load for-thi;s.;faci,l.i.ty (as dei'4ned i: n NUREG-0612, Article,1..23
's 1000 pounds..2.2 Heav Load Overhead Handlin S stems This section reviews the applicant's list of overhead handling systems which are subject to the criteria of NUREG-0612 and a review of the justification for excluding overhead handling systems from the above mentioned list.2.2.1~Sco e"Report.the results of your review of plant arrangements to identify all overhead handling systems from which a load drop may result in damage to any system required for plant shutdown or decay heat removal (taking no credit for any interlocks, technical specifications, operating procedures, or detailed structural analysis)and justify the exclusion of any overhead handling system from your list by verifying that there is sufficient physical separation from any load-impact point and any safety-related component to permit a determination by inspection that no heavy load drop can'result in damage to any system or component required for plant shutdown or decay heat removal."
A.Summar of A licant's Statements The appliaan'review ofoverhead handling'systems identified the cranes and hoists shown in Table 2.1 as those which handle heavy loads in'he vicinity of irradiated fuel or safe shutdown equipment.
The applicant has also identified numerous other cranes that have been excluded from satisfying the criteria of the general guidelines of NUREG-0612, These are indicated in Table 2.2.These various overhead handling systems were reviewed by the applicant with regard to criterion NUREG.0612.and.were..excluded based on.plant specific conditions of plant shutdown or because the loads were not greater than 1000 lbs.The applicant also stated that a heavy load was considered to be any load in excess of 1000 lbs.This was the most realistic weight limit to evaluate because many cranes monorail.s and hoists were rated in units of 1/4, 1/2 or 1 ton units.In addition the weight of some loads was estimated and a convenient unit (1/2 ton)was conservatively used for relatively small loads.The applicants introductory remarks in the submittal indicate that the main objective in responding to NUREG 0612 is to insure that all handling of overhead loads at SSES No.2 is accomplished:in a safe and efficient manner by.providing operators with proper training, operating procedures and the equipment safeguards necessary, and by insuring that as many overhead operations as possible are performed along defined safe load paths.When loads are to be handled in the vicinity of new or spent fuel or nuclear safety related equipment, the ultimate objectives are to insure 1.radioactive release, as a result of a potential load drop is less than the requirements of 10 CFR Part 100.
2.damage to fuel will not result in K of greater eff than.95.3.damage to the reactor pressure vessel will not result in uncovered fuel 4.damage to equipment will not result in loss of safe shutdown capability to remove decay heat.PP&L review of the overhead load handling systems consisted of a physical walk down of all cranes, monorails, and hoists in the reactor building, visual inspections to verify that loads with l.arge physi.cal dimens.i.ons cauld-be.safely moved within defined load paths without impacting safe shutdown equipment in the event of a load drop, and by reviews of the affected drawings with cross checks of the SSES equipment index.Consideration was also devoted to the lateral movement of loads due to deflections caused by the possibility of loads striking structural members.Where cranes or monorails travel over hatches or access ways, the lower areas were visually inspected for the potential impact of a load drop.Table 3 of the submittal, I'43 lists the"cranes requiring Detailed Review", the heavy loads associa ed-with each handling system from which a load drop could potentially impact safety-related equipment or fuel.The table includes crane identification, crane location, (building and elevation), load identification and weight, safety related equipment that could be impacted, and hazard elimination category.

'PP&L'-s evaluation'is similar to the subm:ittal for Unit 1, PP&L has provided the results of.heir review and identify any potentially hazardous load handling operations which will require special procedures or equipment modifications to insure the intent of NUREG 0612 is met.The review appears to be adequate.C.EG&G Conclusions and Recommendations
'Since there is no information to the contrary, EG&G concludes that..the.
applicant Ihas.incl,uded:all applicable hoists and cr nes in their list of handling systems which must comply wizh the requirements of the oeneral guidelines of NUREG-0612.
2.3 General
Guidelines This section addresses the extent to which the applicab'le handling systems comply with the general guidelines of NUREG-0612, Article 5.l.l.EG&G's conclusions and recommendations are provided in summaries for each guideline.
The NRC has establ-i shed.seven general guidel'ines'which must:be met in order to provide the defense"in-depth approach for the handling of heavy loads.These guidelines consist of the following criteria from Section 5.1.,1 of NVREG-0612:
o Guideline 1-Safe Load Paths o Guideline 2-Load-Handling Procedures o Guideline 3-Crane Operator Training 10
~v pl~I 1~o Guideline 4-Special Lifting Oevices o Guidel~ne'5-Lifting'Oev'ices (rrot specially designed)o Guideline 6-Cranes (Inspection, Testing, and Maintenance) o Guideline 7-Crane Oesign.These seven guidelines should be satisfied for all overhead handling systems and programs in order to handle heavy loads in the vicinity of the reactor vessel, near spent fuel in the spent-fuel pool, or in other areas where a load drop may damage safe',shutdown systems.The succeeding.paragraphs.,addrese the guidelines individually.
2.3.1 Safe Load Paths Guideline 1 HUREG-0612, Article 5.1.1 1"Safe load paths should be defined fo-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 dropped, 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.Oeviations from defined load paths should require written alternative procedures approved by the plant safety review committee." A.Summar of A licant's Statements The applicant states"Plant Staff engineers have reviewed the load handling systems for the purpose of identifying safe load paths relative to safety equipment and spent fuel.Figures 1 thru 10 were marked to indicate the safety related equipment, spent fuel and paths chosen.These paths were defined for handling systems, that fall under the area of concern with respect to NUREG 0612, and were of the 11 I~~~i bridge crane type.Monorails were excluded from this analysis, since load movement is dedicated by the monorails itself'.'Safe load paths will be clear'ly marked on the refueling deck prior to initial fuel loading." B.EG8G Evaluation EG&G has reviewed the applicant's response regarding safe load paths and the drawings provided, and considers the intent of guideline 1 of NUREG 0612 to have been satisfied.
PPEL has indicated the manner in which implementation of a temporary change to.existing defined safe load paths is to be made and the method of obtaining approvals for this deviation.
C.EGEG Conclusions and Recommendations Based on the information provided EGEG concludes that SSES No.2 is in compliance with the intent of guideline 1 of NUREG 0612.2.3.2 Load-Handlin Procedures Guideline 2 NUREG-0612 Article 5.1.1 2"P.ocedures 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 NUREG-0612, These procedures should include: identification of required equipment; 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." 12 A.Summar of Applicant's Statements
'The appl icant states"'PP'&L has'prepared'general operating procedures for overhead handling systems.These procedures include precautions and guidelines to be observed while operating the systems.In addition to crane operating procedures, PP&L has developed special handling procedures for major heavy loads.Such procedures supplement the general crane operating procedure by providing additional precautions, and a safe load path for the unique load.Generic safe load paths have been incorporated into the Reactor Building Crane.operating,.procedures..Work instructions for specific lifts include the saf~load paths for the particular.
loads.The safe load paths are recorded in"quality" procedures which fall under the auspices of AD-gA-101"Procedure Program".The provisions of this procedure allow the implementation of a temporary change which involves signatures of the plant shift supervisor and one other member of the plant management prior to implementation and review by the plant operational Review Committee within)4 days of the implementation of the change." Specific procedures have been written for the following loads 1.Reactor wall shield plugs 2.Orywell head 3.Vessel head 4..Steam dryer 13 5.Steam separator 6.'Pool pates 7.Dryer/Separator pit shield plugs 8.Slot plugs 9.Vessel service platform 10.Vessel heat, insulation The reactor.bui lang.crane;operating.pnrcedur e HT-99"001 includes a generic safe load path and general instructions for miscellaneous loads not covered by specific instructions.
Included in the general procedure will be the transport of the replacement fuel racks, the crane load block and plant equipment.
Written procedures for the handling of the Spent Fuel Shipping Cask, and the Waste and Debris Cask have not yet been prepared since the casks have not yet been purchased.
S.EG8G Evaluation The applicant has prepared a list of the load handling procedures which have been written, In this list is also indicted these loads which are to be handled within the scope of the Reactor building crane operating procedures.

This standard should apply to all special lifting devices which carry heavy loads in areas as defined above.For operating plants, certain inspections and load tests may be accepted in lieu of certain material requirements'n 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 stress design factor on only the weight (static load)or the load and of the intervening components of the speci'al handling'device." A.Summar of A licant's Statements SSES No.2 will employ the same special lifting devices which are used at Unit 1.Sling selec ions for loads which do not have special lifting devices will be governed by the same procedures as previously reviewed for Unit 1.The applicant stated in his submittal for Unit 1"Slings and Special Lifting Devices have not been procured for use at SSES except the strong back used for the RPV head and the'lifting device for the dryer and separator.
These items have been designed and supplied by the NSSS vendor.Sufficient information is not yet available for determining full compliance with ANSI 830.9-1971:
however the strong back for the RPV has been proof load tested to 125 tons, inspected by magnetic particle examination and used to move the RPV head for Unit 1, and the dryer/separator lifting device meets the proof loading requirements of ANSI 830.9-1971 and has been inspected by 16

ANSI 830.2, 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.Summar of Ao licant's Statements The applicant states"PP8L has developed a preventative main'te'nance program to include al'1'cranes and hoists.This program will include requirements for inspection, testing and maintenance in accordance with the guidelines of chapter 2-2 of ANSI 830.2-1976 with the exception that tests and inspections will be performed prior to use where it is not practical to meet the frequencies of ANSI 830.2 for periodic inspection and test or where frequency of crane use is less than the specified inspection and test frequency.
The diesel building cranes (OH 501A, 8, C and 0)and the 19 reactor building crane (2H213)have been used during plant construction.
The construction group has performed the necessary.itrspecting, testing,'and'maintenance requirements of Chapter 2-.2 ANSI 830.21967." BE EG&G Evaluation The projected preventive maintenance program is in accordance with ANSI B30.2 1976 except that tests and inspections will 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.
In.these inst aces the change in inspections frequencies is acceptable.
