1.0 INTRODUCTION
Quadrex Corpor~tion is providing technical assistance to Public Service Electric and Gas Company (PSE&G) in evaluating the control of heavy loads in the Salem Nuclear Station, Units 1 and 2, per USNRC's NUREG-0612 (-reference 1) and NRC's letter to the plant owners requesting implementation (reference 2). This report presents the results of the review of the plant overhead handling systems and addresses the status of the plant in accordance with the requirements of the six-month report called for in reference 2. The order in which the results have been arranged is identical to that shown in section 2-1 of enclosure 3 to reference 2.
One Quadrex engineer surveyed the Salem Nuclear Plant and interviewed the p1ant personne 1 to prepa*re. a 1i st of overhead handling systems which is shown in section 2.0. Among these handling systems, section 3.0 presents the cranes and monorails which are excluded from evaluation.
Justifications for exclusions are also provided in this section.
The safe load paths for t~e movement of each of the heavy loads as well as the safety-related equipment and spent fuel in the vicinity of the load paths are identified in section 4.1. Section 4.2 discusses the measures to ensure load handling within safe load paths. A tabulation of heavy loads to be handled by each crane including the lifting devices and the drop height is presented in section 4r3.
Section 4.4 summarizes the design .verification for the lifting devices associated with the various heavy loads. Section 4.6 presents the verification for the design of the overhead handling systems from which a heavy load drop may result in damage to safety-related components for plant shutdown or decay heat removal. Written procedures for crane inspection, testing, *maintenance, and operator training are mentioned in section 4.5. Recommendations for actions in the next phase study are presented in section 5.0. Appendix C includes the load paths and the safety-related components in the vicinity of *the load paths. Appendix D
- lists the applicable heavy load written procedures.

- 2.0 LIST OF OVERHEAD HANDLING SYSTEMS A list of the overhead handling systems from which a heavy load drop may result in damage to safety-related components required for plant shutdown or decay heat removal is shown in table 2-1.
Since there is no numbering system for the various overhead handling systems, the editorial mark number codes have been assigned to them in
- accordance with the method for equipment identification. Table 2-1 lists all the overhead handling systems by using this mark number code.
The iotal number of overhead handling systems for the entire plant is sixty-eight (68) including the mobile cranes. In the containment building there are nine (9) load handling systems serving elevation 130 feet.
These are cranes 101, 103, 104, 191 in unit 1 and cranes 201, 202, 203, 204, 291 in unit 2. .Cranes 191 and 291 are Mobile Cherry Pickers permanently assigned to the containment buildings (one in each unit). In the auxiliary building, there are thirty-nine (39) overhead handling systems serving different elevations. Out of these, six (6) are used for elevation 122 feet (121, 122, 123 in unit 1, 221, 222, 223 in unit 2); thirteen (13) for elevation 100 feet (130, 132, 133, 134, 135, 136, 137, 138 in unit l; 233, 234, 238 in unit *2;and 131 in both unit 1 and 2); fourteen (14) for elevation 84 feet (141, 142, 143, 144, 145, 146, 147 in unit l; 241,
.242, 243, 244, 245, 246, 247 in unit 2); four (4) for elevation 64 feet (151, 152 in unit l; 251, 252 in unit 2); and two (2) for elevation 55 feet and 46 feet (161 in unit l; 261 in unit 2). In addition, there is one (1) 18 ton Grove Crane (194) used for smaller yard lifts near the auxiliary building. Six (6) cranes (111,112, 113 in unit 1, 211, 212, 213 in unit 2) and two (2) monorails (114 in unit l; 214 in unit 2) are used in the fuel handling buildings. The intake structure utilizes two (2) monorails (171A, B) and (271A, B) for units 1 and 2 respectively, and two (2) mobile cranes [900 Series American Crane (192) and 80 ton Grove Crane (193)] serving the outside*yard near the intake structure.
In the nonsafety-related areas, such as the turbine area and the service building, there are eight (8) overhead handling systems all together.
These are cranes 181, 281, 183, and 282 for the turbine area. In the service building, cranes 184, 185, 186, and 187 service both units.

- 4. 0 EVALUATION IN COMPLIANCE WITH THE GUIDELINES OF NUREG-0612, SECTION 5. 1. 1 With respect to the design and operation of overhead handling systems in the containment and the spent fuel pool area and those safety-related overhead handling systems identified in section 2.0 above, evaluation concerning compliance with the guidelines of NUREG-0612, section 5.1.1 is provided as following:
4.1 Identification of Load Paths and Safety-Related Components The load transfer paths for the cranes which carry heavy loads are shown in figures C-1 through C-20 of appendix C and are listed.in tables 3-1 and 3-2. Safety-related components/equipment in the vicinity of these load paths are also listed in these tables. Since the safety-related components identified in table 3-1 are associated with a dropped lift of less than 1850 lbs (the weight of spent fuel plus fuel handling tool,
- not a heavy load by definition), drop evaluation was excluded. An inspection of table 3-2 and the figures indicated that:
- a. For the polar gantry crane (101, 201) in the .containment buildings, the potential drop of the core support structure, reactor vessel head, missile shield, reactor handling tools, and reactor coolant pump could hit the reactor vessel, primary system piping, or the fuel in the reactor vessel .
.b. For the Mobile Cherry Picker (191, 291) in the containment buildings, the potential drop of the reactor head studs could hit the reactor vessel and the primary system piping.
- c. For the filter handling systems (133, 233; 134, 234; 138, 238; 143,

QUAD-1-81-933
- d. For the solid radwaste crane (131) in the auxiliary building, the potential drop of loaded solid radwaste cask could hit containment spray pumps, charging pump, and associated piping and cables.
- e. For the charging pump monorail (141A, B, C; 241A, B, C) in the auxiliary building the potential drop of the charging pump casing could hit the chemical volume control piping and waste decon tanks on the elevation below floor level 84 feet.
- f. For the component cooling pump monorail (145A, B; 245A, B) in the auxiliary building, the potential drop of the component cooling pump motor could hit waste holdup tanks, monitor tanks, safety-
- related cable trays, and service water piping.
- g. For the safety injection pump monorail (146A, B; 246A, B) in the auxiliary building, the potential drop of the safety injection pump motor could hit the safety injection pump and piping.
- h. For the containment spray pump monorails (142A, B; 242A, B) in the auxiliary building, the potential drop of the containment spray pump motor could hit the associated containment spray piping, service water piping and safety-related cable trays.
- i. For the monorail servtng elevation ~5 feet and 45 feet (161A, B; 261A, B) in the auxiliary building, the potential drop of the residual heat removal pump motor could hit the residual heat removal pump and piping.

QUAD-1-81-933
- k. For the 80 ton ~rove Crane (193) and the 900 Series American Crane (192) in the intake structure outside yard, the potential drop of the service water strainer, concrete cover plug, service water pump motor, traveling screens, and fish gate could hit the service water piping, headers, and the intake bays pump suctions.
- 1. For the cask handling crane (111, 211) in the fuel handling buildings, the potential drop of the spent fuel cask could hit the transfer pool liner, and the spent*fuel in the cask.
The consequences of potential drops of spent fuel casks were analyzed earlier and submitted to NRC (reference 13). The following is a brief summary from reference 13:
- 1) The physical arrangement of the fuel handling buildings is such that the transfer pool is separated from the spent fuel pool. The cask can transfer only over the transfer pool. A spent fuel shipping cask drop could perforate the fuel transfer pool liner plate. However, such an event would not result in loss of water from the storage pool, since the two are physi-cally separated. For this reason, no cask drop analysis was required.
- 2) No heavy loads are handled over equipment required for the safe shutdown of the plant during the movement of fuel from the reactor cavity to the spent fuel pool or vice versa, or the movement of a cask. The handling of fuel is all within the reactor cavity, fuel transfer canal, and spent fuel pool.
- 3) Administrative controls prohibit loads greater than that of a fuel assembly to travel over the spent fuel pool. The maximum height at which a fuel assembly can be carried is restri~ted by limit switches on the crane to 15 inches over the top of

the spent fuel racks. The---spent
- - --~--- - - - --- -- ----
fuel racks have been designed to absorb the energy released by a fuel assembly dropping from 15 inches above them.

QUAD-1-81-933 4.2 A Discussion of Measures to Ensure Load Handling Within Safe Load Paths Movements of heavy loads handled by the overhead handling systems listed in table 3-2 are governed by approved operating procedures. These procedures provide guidance for moving loads from one location to the other. Safe load paths have been defined on general arrangement drawings and are being inc~uded in the procedures. The bounds of these load paths wi 11 be refined and added to pl ant deta i 1 documents as appropriate (reference 17).
Due to plant changes, and changes in th~ operating conditions, in the future it may be necessary to follow load paths other than those shown here. Before any such movement, however, it will be reviewed for safety and wi 11 be. in accordance with an approved operat.i ~g procedure.
Heavy load handling is performed by experienced qualified operators in accordance with approved operating procedures that ensure the movements of heavy loads follow the defined safe load path.
4.3 Tabulation of Heavy Loads, Lifting Devices, and Handling Procedures Heavy loads carried by each overhead handling system are listed in table 3-2. Load identification, load weight, and its designated lifting devices are also given in the table. In accordance with NUREG-0612, no loads.less than 1850 pounds are 'Considered. Handling of these heavy loads are governed by written procedures which meet the requirements of section 5.1.1(2) of NUREG-0612.
In addition to the loads listed, there may .be other infrequent loads which are moved using the overhead handling systems. Handling of any
__ suc:h ~ddit}crnaJ_ l_oads, however, will be performed
- - - - - -- -- - - - -~
after an engineering and safety review and in accordance with approved written procedures.
4-4
QUAD-1-81-933 4.4 Verification That Lifting Devices Comply With the Requirements of ANSI Nl4.6-78 or ANSI 830.9-71 Current procedures for lifting of heavy loads are in the process of being updated to comply with those areas which are outlined in table 3.1-1 of NUREG-0612, pertinent to the Salem Generating Station (reference 12).
Currently, Procedures M2Q (reference 14) and M2S (reference 15) are the only two written documents available for lifting devices. However, no specified lifting devices used for individual heavy load were identified in these procedures. General rigging equipment has been used for lifting except for reactor vessel head and reactor internal structures. Since design calculations and specifications are not available, the lifting devices will be verified after a complete set of drawings, including material definition, is obtained from Westinghouse or by a field survey and analysis.
4.5 Procedures for Crane Inspection, Testing, Maintenance and Crane Operator Training The crane inspection, testing, and maintenance procedures were in place for each overhead handling system and, as necessary, revised in accordance with the ANSI standards (reference 12). A list of these maintenance procedures is presented in table D-1 in appendix D.
Maintenance Procedure M2 is established to provide procedures and asso-ciated checklists to be utilized during the performance of inspections and tests and technical specifications in regard to cranes. It also provides procedures to be utilized during the pre-fuel handling check out of applicable cranes and fuel handling/transfer system components in accordance with Regulatory Guide *1.38 and ANSI N45.2.2.
Procedure MSC details the steps required to prepare the reactor vessel internals, reactor vessel, and the refueling cavity for fuel element and rod control cluster assembly replacement .

QUAD-1-81-933
- The crane operator training and qualification procedures were also developed in accordance with ANSI standards. A list of the qualifi-cation standards for the operators who work in different areas is given in table D-2 in appendix D.

The design specifications of the above cranes were compared with the standard requirements. The results of comparison are presented as follows:
4.6.1 Solid Radwaste Overhead Crane (131)
The heavy loads handled by the solid radwaste crane are listed in table 3-2. According to the detail specification 70-6471 (refer-ence 5) and the standard specification 68-6360 (reference 6), this crane was designed in accordance with the EOCI 61 specification (reference 7) and the ANSI 30.2.0-67 standard (reference 8).
However, after the crane was designed, it was upgraded to meet the CMAA-70 requirements (see the maintenance manual [reference 9]).
For this reason, the design specifications of this crane were reviewed for compliance with the guidelines of chapter 2.1 of ANSI 830.2.0-76 (reference 10) only.
The review of the above-mentioned crane documents showed that the crane design satisfies the pertinent guidelines, that would effect the potential load drop, of ANSI 830.2.0-76, with the exception of the following items.
- a. Crane Construction Different welding codes are used in ANSI 830.2.0-67 and ANSI 830. 2. 0-76. However, .s i nee the crane was built by the manufacturer's manual to meet the CMAA-70 requirements then the welding standards are met since CMAA-70 and ANSI 830.2.0-76 use the same welding code, namely the American Welding Society's 11 Specifications for Welding Industrial and Mill Cranes,"
Aws* 014.T-(reference-22). - -
- b. Stops, Bumpers, Rail Sweeps, and Guards
- ANSI 830.2.0-76 specifies that trolley bumpers have sufficient absorbing capacity to stop the tro 11 ey, when trave 11 i ng with power off at a speed of 50% of rated load speed (section 2-1.8.3).
4-8
QUAD-1-81-933 There is no .such clause in either ANSI 830.2.0-67*or CMAA-70.
More information is required to check whether the trolley bumpers have this energy absorbing capacity; such as bumper.
stiffness and maximum contraction of bumpers.
- c. Brakes Section 2-1.9.Sb of ANSI 830.2.0-76 states that "emergency braking means shall have the capability of decelerating the trolley or bridge from full load speed to 40 percent of full load speed in the distance specified in 2-1.9.Sa. 11 This paragraph is not listed in ANSI 830.2.0-67. The rated torque of the brakes for the trolley and the bridge will be checked to verify this requirement.
- d. Hoisting Equipment ANSI 830.2.0-76 states that hook latches, if used, shall conform to ANSI 830.10. ANSI 830.2.0-67 does not have a clause on hook latches. Latches are used in the radwaste crane. However, the requirements of the new safety standard represent a codification of good engineering practice and they are expected to be similar to design standards used earlier.
4.6.2 Filter Handling System Cranes (133, 233; 134, 234; 138, 238; 143, 243)
There are three types of crane for handling the filter system; namely monorail bridge crane, underhung bridge crane, and monorail crane.
- a. Monorail Bridge Crane and Underhung Bri~ge Crane (143, 243; H - HH ----- ---- ------------- H -- -----1-34--.-- --234-) --- H ------ H - HH - - -- --: HH rn -- H ----- H --- ------------ - --- ------- H --- -
The standard specification 68-6360 (reference 6) indicates that the monorail bridge crane and underhung bridge crane were designed based on EOCI 61 and ANSI 830.2.0-67. However, the design for these cranes was upgraded to meet the CMAA-70 standards by the manufacturer after they were ordered (see 4-9
.~
QUAD-1-81-933
- technical manual reference 11). For this reason, the design specifications of these cranes were reviewed for compliance with the guidelines of ANSI 830.2.0-76 only.
The review comments for the monorail bridge crane and underhung bridge crane are identical to those for the solid radwaste cranes (131) discussed in section 4.6.1, since the design specifications are identical.
~
- b. Monorail Crane (133, 233; 138, 238)
The only information available on this crane is in the technical manual (reference 11), which indicates that this crane was designed to CMAA-70 requirements. A comparison between CMAA-70 and ANSI 830.2.0-76 showed that the crane design satisfies the pertinent guidelines that would effect the potential load drop. However, more information is required to complete this comparison.
4.6.3 Polar Gantry Cranes (101, 201)
The standard specification 68-6360 (reference 6) indicates that this crane was built in accordance with the EOCI 61 specification and the ANSI 830.2.0-67 standard. The design specifications of this crane were reviewed *for compliance with the guidelines of CMAA-70 and chapter 2.1 of ANSI 83.2.0-76. Supplementary infor-mation obtained from the Whiting Corporation report "Engineering Design Study of Salem Nuclear Station Cranes" (reference 3) was also considered. The analysis methodology and the interpretation of CMAA-70 in relevant sections of the Whiting report were reviewed.
The review of the above-mentioned crane documents showed that the crane design satisfies the pertinent standards of CMAA-70 and ANSI 830.2.0-76 with the *xception of the following items:
4-10
- QUAD-1-81-933 4.6.3.1 Structural Design Compliance With CMAA-70 and ANSI 830.2.0-76
- a. Material EOCI 61 specifies the steel to conform to the ASTM-A7 standard but CMAA-70 specifies the steel to conform to the ASTM-A36 standard. This area has been investigated in more detail and found that the polar gantry cranes were built with ASTM-A36 steel. Therefore, CMAA-70 standard is met.
- b. -Welding Both CMAA-70 and ANSI 830.2.0-76 follow the welding design and procedures of AWS 014.1 (reference 22). ANSI 830.2.0-67 states that welding shall conform to the American Welding Society's 11 Specification for Welded Highway and Railway Bridges, 11 AWS 02.0-66. However, in our judgement, because of the margin of safety inherent in the code allowable values, the use of AWS 02.0-66 would not cause any safety problem.
- c. Impact Allowance EOCI 61 takes the girder impact allowance as 15 percent of .the rated capacity. CMAA-70 takes the impact allowance .as 1/2 percent of the load per foot per minute of hoisting speed but not less than 15*percent or more than 50 percent of the rated capacity. Review calculations showed that the impact a 11 owance, as ca 1cul ated by the CMAA-70 formula, is 1ess than 15 percent. Therefore, impact allowance satisfies the CMAA-70
~*
requirement.
- d. longitudinal Stiffeners The Whiting report indicates that the longitudinal stiffener
--- .. -;s placed deeper-down the girder-web -than *required by-CMAA-'70-.-
Therefore, it does not satisfy the CMAA-70 requirement. However, because of the margin of safety, this variation is considered to be acceptable.
4-11
QUAD-1-81-933
- e. Basic Allowable Stresses Although EOCI 61 and CMAA-70 use different specifications for structural steel, the Whiting report shows that the allowable
- stresses for tension, compression and shear in EOCI 61 is more conservative than CMAA-70. CMAA-70 limits bearing stresses to
- 26. 4 ks i. Si nee EOCI 61 does not have a cl a use on bea_ri ng stresses, only a check of the design calculations will reveal whether -this section of CMAA-70 is satisfied.
(
- f. Rails CMAA-70 states that 11 provi s ion sha 11 be made to prevent creeping of the bridge rails by means 9f a positive stop at the end of the rail." No such provision is listed either in
'l..._,:
EOCI 61 or ANSI 830.2.0-67. However, investigation shows that stops have been provided at the ends of the bridge rails.
- g. Gantry Cranes CMAA-70 states that the design of leg, end tie, strut and sill members of gantry cranes shall conform to the applicable
-sections of the current edition of the steel construction manual as published by the American Institute of Steel Construction. EOCI-60 does not list a comparable section.
However, investigation *shows that these members -were designed
-with allowable stresses .more conservative than those listed in AISC manual.
4.6.3.2 Mechanical Design Compliance With CMAA-70 and ANSI 830.2.0-76
- a. Hoisting Ropes CMAA-70 states that the rated capacity load plus the bottom
-- ---- ----~-----------------b~ock-di-v-ided bye-the number of--parts of-the-rope-shal-1--not- - -- ----------- -----
exceed 20 percent of the strength of the rope. EOCI 61 and ANSI 830.2-67 exclude the weight of the bottom block in calculating the rope stress. However, review calculations 4-12
QUAD-1-81-933 showed that inclusion of the bottom block would only reduce the safety factor for the rope from 5 to 4.87. This variation is considered to be acceptable in the design.
- b. Sheaves The design satisfies all the pertinent criteria of CMAA-70 and ANSI 830.2.0-76 except one clause relating to rope inspection for the continued use of the rope when there is a significant reduction in the rope diameter. The ANSI 830.2.0-76 criteria are slightly more strict than ANSI 830~2.0-67 on this subject.
However, the criteria only present a good maintenance practice and it is not expected to be of consequence.
- c. Drum CMAA-70 provides recommended drum groove depth and pitch.
EOCI 61 provides no similar guidance. The recommendations in CMAA-70 constitute a codification of good engineering practice with regard to stability and reduction of rope .wear and are not expected to differ substantially from practices employed in the design of cranes subject to this review and built to EOCI-61 specifications .
. d. Gearing CMAA-70 requires that gearing horsepower rating .be based .on certain American Gear Manufacturers 1 Asso.ci ation Standards -and provides a method for determining allowable horsepower.
EOCI 61 provides no .similar guidance. The recommendation in CMAA-70 constitute a codification of _good engineering practice for gea*r design and are not expected to differ substantially from the practices employed in the design of cranes subject to

QUAD-1-81-933
- e. Brakes ANSI 830.2.0-76 states in section 2~1.9.5b that: emergency braking means shall have the capability of decelerating the trolley or bridge from full load speed to 40 percent of full load speed in the distance specified in ANSI 830.2.0-67. The rated torque of the brakes for the trolley and the bridge will be checked to verify this requirement. Furthermore, the value of the motor torque of the trolley also will be obtained to check section 2-l.9.6b of ANSI 830.2.0-76.
- f. EOCI-61 does not give detailed design requirements for shafts.
However, the requirements of CMAA-70 represent a codification of good engineering practice and they are expected to be similar to design standards used earlier.
- g. Bumpers and Stops The trolley bumper design will b.e checked to see whether it has the energy absorbing capacity to stop the trolley when traveling with power off in either direction at a speed of at least 50 percent of rated load spe_ed as required by ANSI B30.2.0-76 requirements. Required information is the bumper stiffness a~d the maximum contraction of the bumper. However, since these cranes are not expected to be operated under load at substantial bridge or trolley speed near the end of travel, the energy absorbing capacity is -expected to be sufficient.
4.6.4 Cask Handling Cranes (111, 211)
The standard specification 68-6360 (reference 6) on bridge and gantry cranes indicates that this crane was built in accordance with EOCI 61 and ANSI 830.2.0-67 standard. Whiting Corporation has also reviewed the design specifications for this crane to show the compliance with CMAA-70. The review comments for the cask handling
- 4-14
QUAD-1-81-933 crane are very similar to those for the polar gantry crane since the design specifications are almost identical. Following is the only comment to the section where the design of the two cranes is not similar.
Longitudinal Stiffeners The Whiting Corporation report indicates that the longitudinal stiffeners are not placed on the girder webs in the locations.
listed in CMAA-70. Furthermore, the moment on inertia of the longitudinal stiffeners are less than CMAA-70 requirements. However, because of the margin of safety in the new code this variation is considered to be acceptable.
4.6.5 Fuel Handling Cranes (112, 212)
Standard specification 68-6360 (reference 6) on bridge and gantry cranes indicates that this crane is built in accordance with EOCI 61 and ANSI B30.2.0-67 standards. Whiting Corporation has also reviewed the design specifications for this crane to show compliance with CMAA-70. The review comments for this *crane are similar to those for the polar gantry crane since the design specifications are almost identical. Following are comments to sections where the design of the two cranes is not similar.
\...:
- a. Proportions The f o11 owing information o.n the bridge girder Vii 11 be 'obtained for verification purposes: the depth and the .thickness of the web.
- b. Longitudinal Stiffeners If longitudinal stiffeners are used, then a detail drawing showing the location of the stiffener in the girder and the size of stiffener is needed for checking purposes.

QUAD-1-81-933
- 4.6.6 Mobile Cranes (191, 291, 192, 193, 194)
There are five mobile cranes in the Salem Nuclear Station. Two of the Mobile Cranes (191, 291) are permanently assigned to the containment buildings (one in each unit). Both the 900 Series American Crawler Crane (192) and the 80 ton Grove Crane (193) are used to service the intake structures as well as for movement of large loads in the yard. The 18 ton Grove Crane (194) is used for smaller yard lifts. It is also used to lower loads from auxiliary building roof down to the hatchway near the elevator.
Heavy loads carried by each mobile crane are given in table 3-2.
Design specifications and calculations for all mobile cranes are not available. Since NUREG-0612 (reference 1) does not mention the design verification for mobile cranes, therefore, it was not performed in this report. In the next phase study, the appropriate commercial standards for these special mobile cranes, such as ANSI B30.3 (for mobile and locamotive crane) and ANSI B30.5 (for mobile and hydraulic crane), will be used for design verification. A brief description for each mobile crane is given as follows:
- a. Mobile Cherry Pickers (Galion Cranes 191, 291)
Two mobile cranes are permanently assigned to the containment buildings (one in each unit). They are operated on the operating deck (elevation 130 feet) to bring in items and equipment through the equipment hatch, to lower items into the cavity and to handle reactor head studs and nuts during cleaning. The .safety-related components in the vicinity of the load paths are the reactor vessel, primary system piping, or the fuel in the reactor vessel.
- b. 900 Series American Crawler Crane (192) and the 80 Ton Grove Crane (193)
Crane 192 is rated at 225 tons with short boom (70 feet). It travels on two tracks. Both crane 192 and crane 193 are used 4-16
r, QUAD-1-81-933
- to service the intake structure for removal and installation of service water motor, pump, and strainer, as well as for movement of large loads in the yard. Awkward shaped equipment like the traveling screen assembly is handled only by the American crane because of its long boom. Presently when lift is made at the intake structure, load is swung to either side of the building then lowered. Items from the lower bays are lifted through the deck opening then raised *high enough to clear windbreak wall before lowering along side structure (see figure C-20). It may be worthwhile to consider providing a removable windbreak section to keep load lift lower. 'The potential problem exists when removing strainer through the overhead opening since the opening is partly over the piping header.
The only heavy loads that have even been carried across the service water yard piping while suspended from a mobile crane (192 or 193) are the service water pump motor (13,200 lbs) and the service water pump (12,000 lbs). All other loads crossing the yard piping have been carried by truck or trailer.
,--' - ' During the transport, the service water motor or pump was
.suspended approximately one foot above the ground. The two foot inside diameter *concrete yard piping runs between the intake structure and *the auxiliary building. The burial depth for the piping is eight feet everywhere except the portion near the auxiliary building at which the burial depth decreases to 4 ft-4 fn. From the ground surface to the center line of the piping the soil is 95 percent compaction fill.
From 8 ft to 20 ft below the surface, the soil density

QUAD-1-81-933 Based on the above information, a drop analysis was performed and the result indicated that the yard piping is subjected to very low stresses due to such a heavy load drop even for the burial depth of 4 ft-4 in. Besides, based on service water piping diagram 205242-A-8761 all portions of the service water system are redundant. Therefore, the yard piping damage due to a heavy load drop is not an issue.
- c. 18 Ton Grove Crane (194)
This crane is used for smaller yard lifts outside the auxiliary building. It is also used to lower loads from auxiliary building roof down to the hatchway near the elevator. To get to its lift location, this crane is picked r up by the main turbine building crane at either end of the turbine building and carried to between the two high*pressure turbines. It is lowered to the turbine deck at elevation 140 feet and then driven acros.s the steel p1ates to its 1i ft .
location. See paths outlined in figure C-18.

5.0 CONCLUSION
S AND RECOMMENDATIONS 5.1 Conclusions The review results of the overhead handling systems, described in the earlier sections, are summarized and presented below:
- a. Design verifications for the following cranes have been performed:
- So 1 id Radwaste Crane in the Auxiliary Bui 1 ding (131);
- .Filter Handling Systems in the Auxiliary Building (133, 233; 134, 234; 138, 238; 143, 243);
- Polar Gantry Crane in the Containment Buildings (101, 201);
- Cask Handling Crane in the Fuel Handling Buildings (111, 211);
- Fuel Handling Crane in the Fuel Handling Buildings (112, 212).
It was found that they were originally designed in accordance with the EOCI specification. The review of the available crane documents showed that the general and qualitative design requirements for these cranes satisfy the pertinent guidelines of CMAA-70 and ANSI B30.2.0~16 except the items listed in section 4.6.
However, in the reviewer's judgement, these deviations are considered to be well within the margin of good design, and are not likely to result in any safety problem if the maintenance, operation, testing and inspection procedures are rigorously followed. Evaluation of the effects of these non-conformances could be addressed in the nine-month report.
c
- b. In addition to the cranes listed above, there are seven more mono-rails in the auxiliary building, two monorails in the intake structure, and five mobile cranes in both units from which a heavy
, -~ - -- - --- ------- -- load--drop may_als.o result in __damage_ t_o satety-reJatE!d_~omponents_.
However, no design documents are available. Design verification is being initiated and modification will be made as is necessary; such as the monorail capacity.
5-1
QUAD-1-81-933
- c. General rigging lifting devices are used for most of the heavy loads except the reactor head and reactor internals. For the general rigging devices, no specific devices have been ider.tified for individual heavy loads. Although the special lifting devices for the reactor head and reactor internals have be~n indicated, a complete design verification should be performed in the next phase study.
- d. Load paths for heavy load drop for all the overhead handling systems have been identified. Safety-related components in the vicinity of the load paths have also been indicated in tables 3-1 and 3-2. Additional evaluations will be .made per NUREG-0612 to ascertain whether the potential drop would be acceptable, or whether appropriate minor crane modification should be made, or whether the load paths should be modified to exclude them from the list shown in table 3-2. These evaluations will be part of the next phase scope of work and.should be submitted to NRC in the nine-month report.
I
- e. Current procedures for lifting of heavy loads have been updated to include the safe load paths and the bounds of these load paths on general arrangement drawings. The crane inspection, testing, and maintenance procedures were developed in accordance with ANSI standards.
c
- f. Mobile cranes 192 and 193 are used in the yard around the service water piping. The result of a drop analysis indicated that the yard piping is subjected to very low stresses due to a heavy load drop even for the worst case. Besides, based on service water

- 5.2 Recommendations Based on the above studies qualification programs are recommended as follows for the next phase* study (nine-month report) and immediate actions. However, most of the recommendations are for future purpose.
5.2.1 Future Recommendations (Nine-Month Report)
- a. Containment Polar Cranes (101, 201)
These cranes handle a large number of heavy loads over the reactor pressure vessel and other safety-related components. In order to qualify these cranes for exclusion, consequence of drop accident studies, including radiation releases could be provided; perhaps with probability of occurrances and finally with administrative
,,-. control and minor modifications to the polar cranes which would enhance their reliability and hence improve the probability numbers.
~*
- b. Cask Handling Cranes (111, 211)
It has been mentioned that the physical arrangement of the fuel handling building is such that the transfer pool is separated from the spent *fuel pool. The cask can transfer only over the transfer pool. Administrative controls prohibit loads greater than that of a fuel assembly to travel over the spent fuel pool. The conse-quence of potential drops of spent fuel cask into the transfer pool liner were analyzed earlier and showed that such an event would not result in 1oss of water from the storage poo 1. For this study, the c effects on the cask itself were not determined. It is recommended that when the cask is selected in the future, an investigation should .be made to assure if the cask would be a point of considera-tion.
- c. Filter Handling Systems (133, 233; 134, 234; 138, 238; 143, 243)
It is recommended that two worst-case drop evaluations may be necessary to envelop the consequences of all potential drops. Out of these two analyses, one should be for the radiation release (filter inside the bell, waste gas compressor package) and the 5-3
QUAD-1-81-933 other should be for the targets below the 1 ft-8 in. thick floor slab. This recommendation is based on the following reasons:
The filter handling systems are provided for safe removal and handling of cartridge type filters which are housed in the shielded compartments. The transfer bell was designed and built to provide maximum operator shielding during filter transfer. The load-drop-affected components are the filters inside the bell, and the 18, 28.motor control center, associated cable trays, component cooling
,r*.
heat exchanger, waste gas compressor package, and the safety-related cable trays and piping which are located on the elevation below.
Damage to the waste gas compressor package and the filters inside the bell is not essential for safe shutdown but could cause
(. radiation release. All the safety-related cables and piping on the elevation below should be redu~dant. (The concern is separation.)
In order to damage these cables or piping heavy load has to perforate the 1 ft-8 in. thick floor slab (drop height in this case is 7 ft and the weight of the load is 8,500 lbs). lB and 28 motor control center and the associated cable trays should.also be redundant and can be excluded in the evaluation. Damage to the component cooling water piping could cause temporary loss of component *cooling heat exchanger.
. d. Solid Radwaste Crane (131) c There are no known safety-related items or hazards materials in the waste handling area at elevation lOO_ft.of the auxiliary building .
.In order to hit the safety-related equipment *on the next floor
~ (elevation 84 ft), heavy loads have to perforate the'floor at
-~- -- --- ---- ------------- - ----- ~---- -~ -- ~ -~-- --- -- ---~---- ---~- ----- ----- - - ---- - - ---- -- - - - ~--*-- -- --* ------ ---- -- -~-------
elevation 100 ft which is 1 ft-8 in. thick. The drop height in this case is 14 ft and the maximum impact load is 48,000 lbs.
5-4
QUAD-1-81-933 The containment spray pumps and their discharge lines at eleva-tion 84 feet are redundant. Damage to a single pump or qischarge line is acceptable. It is recommended that, one or two worst-case drop scenarios will be evaluated to envelop all potential drops.
Additionally, it is assumed that the qualification program for this crane might include one load path modification to take credit for any redundant safety-related systems such as cables and piping.
- e. Fuel Handling Cranes (112, 212)
The expected heavy load carried is only 1850 lbs which by defini-tion is not a heavy load. There is a limit switch installed to I
prevent movement of loads heavier than 2500 lbs over the spent fuel pool. This switch should be revised to the referenced lower limit, or administrative procedures should be developed to precluding movement of loads heavier than 1850 lbs.
- f. Demineralizer and Ion Exchanger Service Monorails (121, 221)
There is a very open area at elevation 122 ft below this monorail.
The only targets are the Chemical Volume Control (CVC) cables running in trays near ceiling at elevation 132 ft. Although these cables should be redundant; it is recommended that lifts be ~ept.
low in.elevation to prevent heavy loads swinging into the cable trays. This could be done by modifying the written lifting procedures.
- g. Auxiliary Feedwater Pump Monorails (144A, B, C; 244A, B, C), Charging Pump Monorails (141A, B, C; 241A, B, C), Component Cooling Pump Mono-rails (145A, B; 245A, B), Safety Injecton Pump Monorails (146A, B; 246A, B) , Containment Spray Pump Manora i 1s (142A, B; 242A, B). Mono-rails Service Elevation 55 Feet and 45 Feet (161A, B; 261A, B)
- the- major safety-related systems involved in a heavy load drop are the cable trays and piping systems. In general, electric cables and piping for safety-related components require redundancy. It is recommended that separation should be verified to preclude common 5-5
QUAD-1-81-933
- mode multiple failure. Redundant safety-related systems should be considered for the heavy load drops from these monorails. In the next phase study, redundancy will be identified and probably most of these monorails will be excluded for evaluation.
5.2.2 Immediate Recommendations The following items are recommedned for immediate action in order to enhance the reliability:
- a. To more clearly indicate the lifting capacity on the lifting devices, such as the monorails.
- b. To more clearly mark the lifting devices of the monorail to distinguish them from the non-lifting devices. This could be done .by painting them with distinctive colors.
