1983 4.0 Precautions and Limitations 4.1
.All Fuel Handling Equipment will have been tested prior to handling the shipping Cask and Fuel Assemblies.
4.2 Positive and accurate records will be maintained at all times.
4.3 Cask shall not be moved outdoors when threat of severe weather disturbance exists.
4.4 Slings, shackles, and cables shall be checked to verify that they appear to be in good working order.
4.5 The cask and all handling tools and equipment are massive and heavy. Many pinch point hazards exist. A very slow swing of the suspended cask will contain a large amount of energy. Be careful in the cask equipment moves.
4.6 The Cask in the upright position is sixteen (16) feet high, which constitutes a fall hazard. Improper rigging can cause a cask or equipment drop.
4.7 The surface of a loaded cask at equilibrium may be uncomfortably hot.
4.8 it is imperative that the cask handling crew be thoroughly familiar with cask equipment, potential hazards and proper l
handling procedure. Also, all safety rules and equipment are i
j available to perform all areas of cask handling safely.
4.9 All personnel.in Fuel Building, taking part or observing work, shall be familiar with Station Emergency Plan and AP for Fuel Failure.

NOV 4 1983 4.0 Precautions and Limitations (continued) 4.10. Cara should be taken to keep the skirt inlet and vent hoses as short as possible. Excessive lengths may result in interference problems. The hoses should be allowed to hang freely but not allowed to become entangled.
4.11 Thorough planning should be done prior to cask immersion to ensure that immersion times are minimized. Normally, the shorter the immersion time, the less severe the contamination problema incurred and associated decontamination efforts.
4.12 Do not allow Cask to dry prior to decontamination.
4.13 Operation of the Fuel Building Bridge and Trolley Crane will be accomplished by qualified crane operators.
4.14 Safety belts will be worn by personnel as necessary to prevent falling into Spent Fuel Pool.
4.15 All hand tools used ever Spent Fuel Pool or Cask Area will have lines attached to prevent their dropping into the pool.
4.16 When fuel handling is in progress, all doors will be shut in the Spent Fuel Building, except for the movement of people or equipment.
4.17 Prior to moving Fuel Building Bridge Crane into the vicinity of the Cask Area, ensure cask crane has been moved clear so as not to obstruct the path of the bridge crane.

- 5.4.9 Open valve V-2 and start the vacuum pump with the gas ballast valve open. Observe the cask cavity pressure using the gauge G-1 using valve V-6 to throttle the vacuum pump suction.
NOTE:
The cask cavity pressure will normally show an initial steep pressure decrease until a pressure corresponding to the vapor pressure of the residual liquid in the cavity is reached. At this point, the cask cavity pressure will remain nearly constant showing a plateau region. This plateau will be observed to be at a pressure equal to the vapor pressure corresponding to the temperature of the cold wall of the cask cavity (anticipated pressure:
14 mbar - 35 abar).
5.4.10 When the vacuum reaches approximately 40 mbar, close valve V-6 and remove blind flange on "B" Connector (Fig. 14) to break vacuum, forcing any water drain into the drain bottle.

OP-4.3 ADDENDUM 1 Page 1 of 2 1.0 Lid Gasket Tightness Testing 4W 2.0 Introduction This Addendum provides the procedure to be utilized for verifying the lid gasket tightness by subjecting the interspace between the inner and outer lid gaskets to a pressure rise test using the VDS installed throught the lid gasket port and Connector "D" as shown on Figure 29 Attachment 1.
3.0 Lid Leakage Rate Test Procedure 3.1 Following torquaing of the lid bolts, remove residual water from lid gasket port opeining "D" with an aspirator.
3.2 Connect the VDS in the Lid Tightness Testing Mode as shown on Figure 29 with valves V-13, V-5 and V-7 closed.
3.3 Start the vacuum pump, with gas ballast valve open, open valve V-13 and begin vacuum drying of the lid gasket interspace by throttling valve V-6 to obtain a vacuum reading of approximately 15-20 abar.
3.4 Continue vacuum drying operations until a vacuum of not less than 10 mbar is obtained as observed on vacuum gauge G-1.
3.5 When the specified vacuum is reached, close valves V-13 and V-6.
Record pressure as measured on gauge G-1 and the time on Form 6
" Cask Leading Leak Tightness Testing Data Sheet".
3.6 Observe the vacuum gauge G-1 for an increase in the test volume pressure for one minute.
3.7 At the end of the one minute, record the observed-pressure from gauge G-1 and time on the Form 6 data sheet.
3.8 Based upon the observed pressure rise (A p) and the testing time, calculate the actual leakage rate" based upon teh formula below and record on the Form 6 data sheet.

The results of teh test are recorded on the Form 6 Data Sheet.
3.0 Cask Tightness Testing procedure.
3.1 Ensure the VDS is lined up in the evacuation mode as shown in Figure 11.
3.2 Open valves V-6 and V-2, check V-1, V-5 and V-7 closed.
3.3 Start the vacuum pump and evacuate the cask until a vacuum of 20-30 mbar is obtained as observed on G-1.
3.4 Close Valve V-6.
3.5 Wait approximately two minutes to allow the cbserved pressure on G-1 to stabilize.
3.6 Note the vacuum reading and the time.
a) Vacuum abar b) Time 3.7 After two minutes, note the following:

ADDENDUM 2 Page2of2 OV 4 ggy 3.9 Actual Leakage Rate (L') Calculation - Based upon the increase in pressure, as observed on vacuum gauge G-1, over the minimum testing time (tain) period, or during a longer time, the actual leakage rate (L') of the cask observed during teh tightness test is determined from the following equation:
L' = (ap) x (V) x ata (t) 1013 abar where: t = actual testing time in seconds Ap a the observed pressure change (decrease in vacuum) during the test in torr v = testing volume in cm L' = actual leakage rate in atm em /sec 3.10 Allowable Leakage Rate (L) - The allowable leakage rate (L) as calculated for a 30-day transport are based upon the calculations provided in the " Safety Analysis Report for TN-8 and TN-9 Packagings," Revision 7, dated September 8, 1976 Annex C to Chapter III, pages 313n through 131t. The allowable leakage rate for a 30-day transport has been established as:
L = 9.2 x 10-10,g,
,3/sec.
3.11 If the test reveals that L< L, the test is acceptable. Record results on Form 6.
3.12 If Cask Tightness Test is not acceptable (L' > L), refer to the l
TN-8L Shipping Cask Operating Manual for instructions or corrective action and retesting.
