POOR QUAUTY PAGES August 9, 1978 FILE: NG-3514(R) SERIAL: CD-78-2207 Office of Nuclear Reactor Regulation Division of Operating Reactors ATTENTION: Mr. A. Schwencer, Chief Operating Reactors Branch No. 1 United States Nuclear Regulatory Commission Washington, D. C. 20555 H. B. ROBINSON STEAM ELECTRIC PLANT, UNIT NO. 2 DOCKET No. 50-261 LICENSE NO. DPR-23 CONTROL OF HEAVY LOADS NEAR SPENT FUEL
Dear Mr. Schwencer:
Your letter of June 12, 1978, requested information on the physical layout of the Robinson fuel handling areas and on the heavy loads which are handled over spent fuel. Submittal of our responses has been delayed a few days beyond your requested schedule due to in-house workload. We hope that this does not cause you undue inconvenience. Your questions and the Carolina Power & Light Company responses for Robinson Unit No. 2 are listed below: Question 1. Provide a diagran which illustrates the physical relation between the reactor core, the fuel transfer canal, the spent fuel storage pool and the set down, receiving or storage areas for any heavy loads moved on the refueling floor. Response: Refer to Figure 1 (attached) which is a diagram of the Robinson Unit 2 fuel handling areas. Question 2: Provide a list of all objects that are required to be moved over the reactor core (during refueling), or the spent fuel storage pool. For each object listed, provide its approximate weight and size, a diagram of the movement path utilized (including carrying height) and the frequency of movement. dDOEr22o577 m*m

Response
Reactor Core Y
- A) The reactor vessel head is removed from and returned to the vessel along path 1 as shown in Figure 2 once per refueling.
Weight - Approximately 57 Tons Dimension - 189 Inches in Diameter Carrying Height - 30 Feet Above Reactor Core B) The reactor upper internals are removed from and returned to the vessel along path 2 as shown in Figure 2 ence per ! refueling. Weight - 43 Tons Dimensions - 170 Inches in Diameter, 15 Feet High Carrying Height - 15 Feet Above Reactor Core
- C) The reactor coolant pump motors are normally moved only when the reactor vessel head is in place. Occasionally, during refueling, the motors may be moved near the reactor vessel cavity, but never over the open vessel, during motor maintenance activities. The areas noted as 1, 2, and 3 on Figure 3 are the areas used for reactor coolant pump maintenance work.
Weight - 68,700 pounds Dimensions - 81 Inches in Diameter, 148 Inches High Carrying P.eight - 40 Feet Above Reactor Core Spent Fuel Storage Pool A) The GE-IF-300 spent fuel cask is the only heavy load carried over the spent fuel storage pool. I Weight - Approximately 70 Tons , i Dimensions - 6 Feet in Diameter, 18 Feet Long Carrying Height - About Two Feet Above the Spent Fuel Pool Surface Question 3: What are the dimensions and weights of the spent fuel casks that are or will be used at your facility? Response: The only spent fuel cask CP&L plans to use is the GE-IF-300 which weighs approximately 70 tons and is approximately 6 feet in diameter and 18 feet long. Question 4: Identify any heavy load or cask drop analyses performed to date for your facility. Provide a copy of all such analyses not previously submitted to the NRC staff.
August 9, 1978
- Mr.'A. Schwenc r ,
Response: In lieu of detailed cask drop analyses, CP&L has committed to the use of single failure-proof cranes and lifting apparatus. Refer to the response to Question 7 for the appropriate references. Question 5: Identify any heavy loads that are carried over equipment required for the safe shutdown of a plant that is operating at the time the load is moved. Ident.ify what equipment could be affected in the event of a heavy load handling accident (piping, cabling, pumps, etc.) and discuss the feasibility of such an accident affecting this equipment. Describe the basis for your conclusions. Response: Due to the location of equipment required for safe shutdown 4 of the plant, the only area to which this item applies is the reactor containment building. The reactor building polar crane operation would not normally occur during reactor operation because of the radiation levels in the vicinity of the crane control cab. In addition, normal circumstances requiring the movement of heavy loads usually dictate that the plant be in a cold shutdown condition prior to moving these loads.
- Question 6
- If heavy loads are required to be carried over the spent fuel storage pool or fuel transfer canal at your facility, discuss the feasibility of a handling accicent which could result in water leakage severe enough to uncover the spent fuel. Describe the basis for your conclusions.
Response: The only load which could result in significant damage to the spent fuel pool would be the spent fuel cask and, as stated above, it could not be part of a credible accident due to the redundancy of the crane and lifting apparatus. + There is no accident involving the fuel "ransfer canal that could result in uncovering the spent fuel because the elevation of the canal is, at a minimum, six feet above the top of the fuel in the spent fuel pool. ! Question 7: -Describe any design features of your facility which affect the potential for a heavy load handling accident involving spent fuel; e.g., utilization of a single failure-proof crane. Response: Carolina Power & Light Company utilizes a single failure-proof crane at Robinson. Details of the crane were . provided to the NRC by letter NG-74-1246 on October 17, 1974 to Mr. Karl R. Go11er.
.; JMt. A. Schwencer August 9, 1978 Question 8: Provide copies of all procedures currently in effect at your facility for the movement of heavy loads over the reactor core during refueling, the spent fuel storage pool, or equipment required for safe shutdown of a plant that is , operating at the time the move occurs. Response: The Robinson Plant does not have any special procedures for movement of heavy loads other than the spent fuel cask movement procedure. Refer to the attached REFUELING INSTRUCTION FT 15.2. Question 9: Discuss the degree to which your facility complies with the eight (8) regulatory positions delineated in Regulatory Guide 1.13 (Revision 1, December, 1975) regarding Spent Fuel Storage Facility Design Basis. Regulatory Position 1: The spent fuel storage facility (including its structures and equipment except as noted in paragraph 6 below) should be designed to Category I seismic requirements. Response: The spent fuel storage pit is of a Class I seismic design as described in the H. B. Robinson FSAR, Section 9.5.2. R<tgulatory Pcsition 2: The facility should be designed (a) to keep tornadic winds and missiles generated by these winds from causing significant loss of watertight integrity of the fuel storage pool and (b) to keep missiles generated by tornadic winds from contacting fuel within the pool. Response: The extent to which the Robinson Fuel Handling Building conforms to Regulatory Position 2 above is covered in CP&L's response to AEC questions of March 24, 1969 and September 17, 1969 in Appendices II and VII, respectively, of Volume 4 of the Robinson FSAR. Regulatory Position 3: Interlocks should be provided to prevent cranes from passing over stored fuel (or near stored fuel in a manner such that if a crane failed, the load could tip over on stored fuel) when fuel handling is not in progress. During fuel handling operations, the interlocks may be bypassed and administrative control used to prevent the crane from carrying loads that are not necessary for fuel handling over the stored fuel or other prohibited areas. The facility should be designed to minimize the need for bypassing such interlocks. . Regulatory Position 5: The spent fuel storage facility should have at least one of the following provisions with respect to the handling of heavy loads, including the refueling cask:
~ ' Nk. A. Schwencer . August 9, 1978
- a. Cranes capable of carrying heavy loads should be prevented, preferably by design rather than by interlocks, from moving into the vicinity of the pool; or i b. Cranes should be designed to provide single failure-proof handling of heavy loads, so that a single failure will not result in loss of capability of the crane-handling system to perform its safety function; or
- c. The fuel pool should be designed to withstand, without '
leakage that could uncover the fuel, the icpact of the I heaviest load to be carried by the crane from the marimum .
- height to which it can be lifted. If this approach is I used, design provisions should be made to prevent the crane, when carrying heavy loads, from moving in the vicinity of stored fuel.
J
- Response
- The spent fuel cask handling crane is a 300-ton rated, single failure-proof crane. Interlocks are provided
< which prevent cask handling crane movement of heavy loads over the stored spent fuel racks at all times. The cask handling crane can maneuver to place the cask in the sit-down area of the spent fuel pool. Refer to Plant Operating 3 Manual, Volume 9, Procedure FT-13. Regulatory Position 4: A controlled leakage building should enclose the fuel pool. The building should be equipped with an appropriate , i ventilation and filtration system to limit the potential release of radioactive iodine and other radioactive materials. The building need not be designed to withstand extremely high winds, but leakage should be suitably controlled during refueling operations. The design of the ventilation and filtration system should be based on the assumption that the cladding of all of the fuel rods in one fuel bundle might be breached. The inventory of radioactive materials available for leakage from the building should be based on the assumptions given in Regulatory Guide 1.25, " Assumptions Used for Evaluating the Potential Radiological Consequences of a Fuel Handling i Accident in the Fuel Handling and Storage Facility for Boiling and Pressurized Water -Reactors" (Safety Guide 25).
. Response: A controlled leakage building totally encloses the spent fuel pit area and provides an appropriate ventilation and i
- _ filtration system to limit the potential release of radio-active iodine and other radioactive material,s. Refer to the H. B. Robinson FSAR, Section 11.2.1.

;Mr. A. Schwenc:r- August 9, 1978 Regulatory 1
Position 6: Drains, permanently connected mechanical or hydraulic , systems, and other features that by maloperation or failure could cause loss of coolant that would uncover fuel should not be installed or included in the design. Systems for maintaining water quality and quantity should be designed so that any maloperation or failure of such systems (including failures resulting from the Safe I ! Shutdown Earthquake) will not cause fuel to be uncovered. These systems need not otherwise meet Category I seismic requirements. Regulatory Position 8: A seismic Category I make-up system should be provided to add coolant to the pool. Appropriate redundancy or a back-up system for filling the pool from a reliable source, such as a lake, river, or on-site seismic Category I water-storage facility, should be provided. If a back-up system is used, it need not be a permanently installed i system. The capacity of the make-up systems should be i such that water can be supplied at a rate determined by consideration of the leakage rate that would be expected 1 as the result of damage to the fuel storage pool from the ! dropping of loads, from earthquakes, or from missiles originating in high winds, i i i Response: . The location of the spent fuel pit cooling and drain piping and connections are such that a major rupture of ; any or all drains or pipes would not drain the coolant in
- the pit to below the level of the fuel elements. In -
addition, a back-up cooling system is available in the event of coolant leakage. Refer to the H. B. Robinson ! FSAR, Section 9.3. l Regulatory Position 7:- Reliable and frequently tested monitoring equipment should be provided to alarm both locally and in a contin-uously manned location if the water level in the fuel storage pool falls below a predetermined level or if high local-radiation levels are experienced. The high-radia-tion-level instrumentation should also actuate the filtra-tion system. i Response: -Monitoring and alarm instrumentation are provided for the i spent fuel pit area to detect inadequate cooling and . excessive radiation levels. Refer to the H. B. Robinson FSAR, Section 11.2. Yours,very,trulx,

'. INTRODUCTION 1;0 'These instructions are designed to ensure the safe operation of the cask handling equipment and the~ proper loading of the spent fuel cask. The IF-300 cask consists, basically, of a shielded vessel (cask) mounted on an
, equipment skid with an integral cooling system. The equipment forms a com-nietely self-contained unit for the shipment of irradiated reactor fuel. 2 The IF-300 cask is designed primarily for rail shipment; however, it may be transported by truck for short distances. 2.0 Precautions 4 2.1 The cask and handling tools are massive and heavy, and many pinch-point hazards exist. 2.2 Even a very slow swing of.the suspended cask can transfer a large amount of energy upon impact, which may result in severe injury to personnel and damage to equipment. 2.3 The cask is 18 feet high in the vertical position, thereby, consti-
'!' tuting a f all hazard. Minimize the time the. cask is in the SFP or the decon area when not attached to the crane.
2.4 Improper rigging can cause a cask or equipment to drop, possibly < resulting in injury to personnel or damage to equipment. 2.5 Personnel should be informed that the surface of the loaded cask at equilibrium temperzture may be uncomfortably hot. 2.6 Improper installation of the closure head can result in radia61on-streaming when the cask is lif ted from a storage pool. Radiation monitoring should be performed during specified periods in the handling operation when high streaming polential-exists. Health Physics shall cover operations for potential radiation hazards. 2.7 Ensure spent fuci pit-level is 12" belew the air vents to prevent spillover during submersion of fuel cask. 2.8 Ensurc 2 persons are in the SFP crane cab when out of the " Restricted Path" mode and operating in the spent fuel building. p 2.9 Do NOT' operate the spent fuel cask crane when the ambient temperature
. ) is equal to or less than 33 F (as indicated by Unit No. 2 computer meteorological data). This applies to cask lifting operations only.
N 3.0 Initial Conditions . 3.1 Ensure the spent fuel cask crane hook has been inspected within the previous 12-month period or last refueling perfad (PT-38.0). Date Inspected m

- h. Using the operating levers (7) on either side of the large enclosure, perform Steps c. through g., above, until the large saclosure is positioned over the center and small enclosures.
WARNING The cask surface is contaminated. Protective clothing may be required, Enclosure opening complete. 4.3 Perform a radiological survey on contact and at three feet from the cask surface. Perform a smear survey. 4.4 Perform a general inspection of the cash and auxiliary equipment. 4.5 Extend the air ducts as follows:
- a. Remove the two rectangular band couplings (1, Figure 4-2),
one per upper air duct. CAUTION Each ecupling should be loosened sufficiently to slide onto the duct. _ Excessive spreading will damage the coupling.
- b. Rair.e the four lock pins (two (2) on the outside of each duct).
Raise each pin until it cicars the top of the guide (3), then turn the pin so that it rests in'the guide and is retained in the open position.
- c. Remove the lock pin (9) on each side of th.c cask, between the vertical duct support leg and the walkway on the skid. ,

4.7 Disengage the overflow drain hose from the upper valve box. 4.8 Kemove ' the four (4) bolts and lower the hinged end panel to a horizontal position at the bottom of the IF-300 cask. 4.9 Remove the cask tiedown' pins. To remove the two 3-inch tiedown _ pins _(5, Figure 4-2) which secure each side of.the cask to the front saddic, remove the four bolts (6) and the two keepers (7) which hold the two pins in place, using a 3/4-inch wrench. The insertion and removal tool (Part No. M22-21) may be used for this. 4.10 Install the lifting trunnions. The tiedown pins are used to pin the trunnion in place. Secure in place using the keepers and bolts noted in Step 4.9. The insertion and removal tool may be used. 4.11 Attach the lifting yoke to the cask crane main hook. All lifts over the spent fuel pit will require the redundant yoke. The nonredundant yoke may be used elsewhere. 4.12 Remove the cask thermocouple connection lead away from cask. 4.13 Attach the yoke to the cask in the following manner: CO
,; a. Using Never-Seez Pure nickel Special Lubricant or eouivalent, lubricate the yoke hooks,
- b. Using the crane, move the lifting yoke perpendicular to the axial centerline of the cask until the yoke hooks are between the cask trunnions and the top cnd of the cask, with the open sides of the yoke hooks toward the bottom end cf the cask.
- c. Using the crane, carefully lower the yoke and guide the yoke hooks to straddle the cask until the open area of the hooks is positioned to accept the cask trunnions.
- d. Move the yoke laterally along the centerline of the railroad car touard the bottom end of the cask until the yoke hooks are directly under the cask trunnions.
CAUTION This operation should be accomplished without using tag lines or other nids'in positioning the yoke in order to avoid possible misalignment during the lift.
- e. Raise and traverse the crane trolicy/ bridge parallel to the centerline of the railroad car until the yoke hooks have simultaneously and fully engaged the trunnions.
- f. Stop the crane and verify that the yoke books are proper]y engaged to the trunnions. .

4.15 Using the. crane, lift and rotate the cask to a vertical position above the tilting cradle by carefully raising.the crane hook and moving the crano trolley / bridge parallel to the centerline of the railroad car in order to maintain vertical load lines. WARNING To avoid injury to personnel or damage to equipment, v.ake certain that visual and oral communication is maintsined at all times between the crane operator and cask b adling personnel. The visibility of the crane operator may be limited. A few degrees before the cask reaches the full-upright position, slowly move the t.olley/ bridge parallel to the centerline of the railroad car so that the vertical lift will maintain the full load of the cask as it reaches the full upright position. This will
-prevent the cask from rocking on the tilting cradle at the top of.the arc. This pivot point is 3 inches off-center; therefore, "rockover" should not occur. ' CAUTION This operation must be donc carefully. Serious damage to the tilting cradle and railroad car may occur if the cask hangs ' in the tilting cradic due to misalignment.
Check thrt the cask is perpendicular to the railroad car in both g directiot.s by holding a 3-foot level to the side of the cask.
*% The cask must be perpendicular before the vertical lif t is
'E -made.
4.16. Lift the cash from the cradle. Stop uhen the cask clears the cradle < by approximately two feet and stabilize the load. Iloid for one minute to check brakes. 4.17 Lower the cask by six inches and hold for one minute to check brakes. 4.18 11f the brakes are verified to be functional, move the cask to the decon pad.and lower into the lower half of the redundant yoke. 4.19- Retract the air ducts and close the enclosure on the rail car to protect.the equipment and prevent plant , personnel accidential con-tamination. 4.20 . Disengage the yoke, and remove lockwire from valves and closure headJsleeve nuts. 4.~21-- Closc "the Decun Building Roof and wash down the cask

l
- a. Remove the valvo caps (dust' covers) from the vent and drain
-valves in the upper;and lower valve boxes on the cask.
i- b. Connect a hose from cask drain Snap-tite fitting in the lower
. valve box to-the DI manifold Snap-tite fittings, ST-4 (Figure 4.4).
1 c.- ' Connect a' hose from the cask vent Snap-tite fitting in the upper-l-
. valve box to the vent manifold Snap-tite fitting ST-5.
i WARNING [ Possible airborne contamination may occur from the cask vent when filling. Ensure proper venting as per the procedure. 4 1 I. .d. Open the cask vent and drain valves.
- gg CAUTION
'g The cask valve handles can be broken if tightened too tight.
3
- e. Open CD-7 and DI water supply, DW-284.
i
- f. When the cask is full, close DW-284. (When flow indication occucs at the vent' manifold flow meter the cask is full).
- g. - Close CD-7 and the cask vent and drain valves.
I h. Remove the hoses from the cask Snap-tite fittings. 1 4.23 Remove the sleeve nuts as follows:
- a. Ensure no gage pressure exists in the cask cavity and the beginning with nut-number one, proceed clockwise and loosen the 32 closure ,
head sleeve nuts. Due to the head' seal preload, each nut should be slackened 10 to 15 degrees, and the sequence repeated as required. 1 4~ , NOTE: . Step a. above, must be performed with care. The total l' proload is-approximately 1/2 inch of gap between flange faces. . Each completc slackening cycle gains less than 1/64 inch of gap.
- A twin head torque wrench is used for this operation. If a nut does not loosen, retighten the nuts on either side of that nut to
-500 foot-pounds of torque. This will take some of the preload from the nut. It can then be loosened.
- b. Remove all but four closure head sleeve nuts, leaving one in each quadrant, 90 degrees apart. Use sleeve nut removal tool MFR-C-10012c place the sleeve nuts in a storage location.

4.39 Remove the wall and roof cover of the spent fuel pit. 4.40 Reattach the yoke to the " min hook of the crane and proceed with attachment of the cask closure head to the yoke. Ensure identical
," orientation of tb. head, yoke, and the cables are used at this point as compared to .rie removal precess. Check the operability of the yoke control system prior to attaching to the cask.
CAUTION The following operation requires great care and skill. Tolerances between the head and cask are small. All contact between the head and cask must be very gentle to avoid damage to the seal ring, guide pins, and studs.
.41 Move the closure head over the pool to the index marks. Place the crane in " Restricted Path" mode.
4 Commence lowering the closure head into the pool, spraying down all parts entering the water. NOTE Due to the position of the cask closure head which is hanging about 1 degree from the perpendicular and swinging slightly), the cask may not align exactly under the crane trolicy index marks. Slight lateral adjustments of the crane may be necessary to assure that the closure head is directly over the cask. Remove from " Restricted Path" mode as required. 4.43 Seat the closure head as follows:
- a. Carefully lower the closure head over the cask so that the holes in the closure head engage the guide pins on the cask.
- b. Continue lowering the crano hook to the index marks on the cable, so that the closure head is seated on the cask and sufficient slack exists in the lifting cables to permit attachment of the yoke to the cask. .
- c. Make the following observations to ascertain that the closure head is seating properly.
(1) Observe the flow of air bubbles around the closure head as the gasket cncers the car.k. A uniform pattern of bubbles completely around the cask indicates proper scating. Execss bubbling on one side indicates a cocked condition. (2) Ascertain that all four cables slacken simultaneously. (3) Observe the pcnctration of the guide pins to see that they have thc same relative seating position observed during closure head removal with the cask in the pool. Skill and experience is required for accurate observation. (4) Using an underwater television camera, perfscope, or other method inspect the gap between the c]csure head and the cask, which should be uniformly about 1/2 inch around the cask. 1 l l
NOTE: The ga:;ket support ring on the closure head must uniformly penetrate the cash cavity about 2 inches for proper gasket seating.
- d. Corrective actions which may be necessary if the closure head becomes cocked include:
CAUTION: Watch for cask movement to prevent the possibility of tipping the cask er breaking the cabics.
. (1) Sicwly raise the closure head from the guide pins. When clear of the guide pins, laterally move the cranc trolley about h inch toward the lov side of the cocked head.
(2) Re-seat the closure head. Inspect for correct scating. Repeat several times if necessary, making slight lateral adjustments to the crane trolley travel. (3) If this fails, it may be necessary to adjust the length ef the cables between the closure head and the yoke. This is accomplished by bringing the closure head out of the pool, and placing it on a pedesta3. Loosen the set screws, adjust the turnbuckles, and tighten the set screws. Raise the closure head above the f:..or and check with a level for a slope which is parallel to the bottom of the pool. Return the closure head to the pool and resume operations. NOTE: The need for the cable adjustment indicates that the closure head uas not parallel to the bottom of the cool because of improper initial adjustment of the cables or because the pad at the bottom of the pool is not level. If the latter is true, the slope of the pad must be determined as accurately as possible in order that the cables may be properly adjusted. Some trial and error may be necessary. (4) If the closure head still does noi seat properly, a guide pin or stud may have been bent during removal operations. In . order to inspect for this condition, the cask must be unloaded. Refer to paragraph 4.37 and transfer the spent fuel back to their original locations. Disconnect the closure head from the yoke and transfer the cask from the pool to the de-contamination pad. A machinist's squarc shall be used to check for a bent condition of any guide pin or stud. Verify. seating of the closure head. WARNING l RADIATION HA7,ARD i A high radiation field is present directly above the cask cavity opening while the closure head is removed. Appro-priate protective measures must be taken in accordance 1 with established procedures. I 1 l l
p t 4.44 Relatch the yoke a:Id cask ror removal from t-he pool in follows: i
- a. Remove the crane from the "ResLricted Path" mode l. Move the crane book laterally (away from the valve boneslon the cask) until the yoko hooks clear-the cask trunnions asi indicated by the'index marks on the cranc-trolley. s f
I
- b. Lower the crane hook until the yoke hooks clearl the bottoms of the cask trunnions. Verify the position by met.ns of the index marks on the crane cables. /
/
- c. Move the crane book laterally to the index ma k centering the hook and_ yoke over the cask. Replace t';e cra te in the " Restricted Path" mode. /
- d. Carefully raise the crane hook until the yoke hooks have engaged the cask trunnions as indicated by the yoke position and cable indnx mark.
- e. Stop the cranc and verify that the yoke hooks are properly engaged to the trunnions.
- f. Lower the engagement assembly latching are.s until seated on the lower half of the redundant yoke.
- g. Actuate the latching pins and ensure latched.
- h. Jog both arms up to remove all slack.
WARNING RADIATION RAZARD Monitor the cask, as it approcher the surface of the pool and emerges, in accordance with radiation protection pro-cedures established at tha n. actor site. If radiation streaming exists (>2.0R/hr) during lift of the cask from the pool, stop the lift and lower the cask back inte the pool until streaming ceases. Ascertain the cause of streaming and
- correct. Streaming may result from improper sealing of the closure head.
4.45 Carefully raise the crane hook until the cask lifts off the floor
.of the fuel storage pool. Stop the crane and check the rii;fing for proper cngagement. Co..'.inue raising the cask, monitoring coptinuously as the top'of the cack approaches the surface of the pool. .Stop the
. lif t uhen the top of the cask reaches the Icvel of the pool rurb and install four closure head sleeve nuts, one in cach quadrant, as a prceautionary measure. Close the cavity vont valve.
NOTE
^
In performing Step 4.43 above, take care to prevent dropping the closure head sleeve nuts ito the pool. 4.46 lising a spray wand, or hose, thoroughly spray the top of the cask. Operate the crane to slowly continue raining the cask from the pool
- \' so that the cask in thoroughly washed with clean uater. Reeve the N plywood nhield f ron the J ot.cr half of the reduntant yoke and ' store in the SFP. Using
." . the cranc, transport the c:mk from the fuel storage poo1 ~ to the decon arca in "Postricted Path" rnde. Carefully lower the cask onto the
'decon pad. Attach t hermocouple wire to cack prior ' to se tting down cack.
4.47 Attach a tenperature recorder (calibrated to accept Type K chrome-Alumel. thermocouple) to the cask thermocouple and start monitoring continuously. Compare the tenperature data taken to temperature-pressure graphs g (provided by Raleigh Fucis Group) to ensure compliance to ship spent
; fuel. (Reference Figures 4.5, 4.6 and 4.7) Complete Form #4.
3 WARNING A radiation field will exist around the gap between the RADIAr10;; cask and closure head which will diminish as the closure IIAZARD head is tightened. WARNING N Depending upon the heat load of the fuel, it may be necessary to flush the cask to maintain a safe working temperature on the cask surface. Flushing is required if the thermocouple reading exceeds 180 degrees Fahren-heit. Refer to Paragraph 4.55.
. 4.48 Disconnect the lower half of the yoke, Remove the head lifting 4 cables and the upper yoke from the cask and store the yoke.
4.49 Close the r.cof cover on the decon area and the confinement structure Decon of Cask may begin. of.the spent fuci pit. 4.50 Remove the four nuts from the head. Remove the short vent hose from the cask and attach a hose from the cask vent to the vent manifold. Open the cavity vent valve and manifold valves to vent the cask. 4.51 Clean all sleeve nuts and studs and apply Never-Seez Pure Nickel Special Lubricant, or equivalent, to threads and turning surfaces. 4.52 Tighten the closure head sleeve nuts. Proceed as follows:
- a. Establish parallelism between the glange faces by adjusting the nuts as required. Tool Numbers M22-15 and M22-8 may be used.
- b. Check parallelism by using a suitable set of feeler gages.

Align the cank nuch that the two undersized fins will .act as guides in the two 1-1/S' inch slots in the tilting cradle. Slouly lnuce the cack into the tilting cradle. When the-cask bottom contacts the socket and the cask honins to tip, simul-toneously lower the crane hook and travel the crane to the opposite end of the equipment skid so that the load line will remain vertical as the cask lowers to the horizontal position. 4 'Be sure that the guide fins are fully engaged in the sockets. NOTE t.'hcn the essk is nearly horizontal , it will engage the head-end support and will be pulled forward app-roximately 1 inch. Stop horizontal travel of the crane uhen the cask is fully seated
' on the equipment skid. Continue down travel of the crane hook until the yoke books are below the cask lifting trunnions. Move the crane laterally until the yoke hooks are free of the cask lif ting trunnions.
4.66' Lift,the trunnions to take up slack to relieve the pins of the load. Disengage the tiedown pin, pin keeper, and bolts from each trunnion. Remove the trunnions from the cask and move to the storage location. Install the tiedown pins through the equipment skld sadd3c, one en each side of the-cask. Secure the pins in place by means of the pin keeper and bolts. Secure the bolts in place with lockwire. Nove the crane as required to transport the yoke to its storage location.- Decon the area where the trunnions had been
\.
installed. 4.67 Lockuire all valves and replace dust caps. Ensure that all salves are tightly closed prior to lockwiring. 4.68 Replace valve box covers and the overflow drain hose. i- 4.69 Perform a radiological survey 3 feet from the surface of the cask. The sum of the products listed below shall not exceed 1000 mr/hr. Neutron dose-rate mr/hr x 111.0 = Gamma dose rate mr/hr x 11.3 = Sum = The sum was less than 1000 mr/hr. - 4.70 Retract air ducts and secure in place. 4.71 Connect the thermocouple to the alarm system. 14.72 Complete the chechout of the cooling system (form 2) and start the engines according to the instructions mounted on the instrument panel. ___ CAUTION To prevent damage to the engine, do not run t he ntarter.

motor longer than 5 seconds, and do not engane the
st.trter motor while the crankshaf t is rotating f rom a provicus start.
- a. Feduce the speed as soon as the eng.ine is operating normally, as indicated by the charging indleator light. .
- b. Verify that the pointer of the oil indicator gauge is in the green field. If the pointer drors back to the red field, immediately stop the engine. Refer to the engine manufacturcr's instruction manual and determine the cause of low oil pressure.
- c. Increase the engine speed to 7300 - 2500 RPM and once it has stabilized, engage the clutch.
- d. Obnerve the overall operation of the engine and drive fan (drive bel ts, bearing vibration, etc.)
4.73 Verify that the cavity thermocouple temperature setting is 3500F, by visually observing the tem,ncrature indicator located in the engine com-partment, above the rear entrance door. 4.74 Turn on the cavity thermecouple temperature alarm switch (located in.the Instrument Panel for Dicsc1 Engine Number 2). If the alarm sound's, push
'the "ACK" switch, located inside the rear entrance to the diesel com-partment. If this action does not stop the alarm, turn off the
~
switch. 4.75 Test the cavity thermocouple temperature alarm system by actuating the test' button, located at the inside rear of the enclosure. 4.76 Ensure proper labeling, placarding and marking of the shipment is done per DOT regulations. 4.77 Ensure proper shipping papers and arrangements have been completed to ship per DOT regulations. 4.78 The cask is ready for shipment. 4.79 The caat has been delivered te :_he carrier.
