| |
| -Applies to operating limitations during ' fuel-handling and refueling operations.
| |
| 1 j - Objectives i
| |
| To ensure that no incident could occur during fuel handling and refueling operations that would affect public health and safety.
| |
| i Specification-A. During refueling operations the following . conditions shall be satisfied:
| |
| : 1. The equipment hatch and at least'one door in each personnel air lock
| |
| ~
| |
| shall be closed. In addition, at least one isolation valve shall be j
| |
| operable or locked closed in each line which penetrates'the contain-
| |
| ' ment and provides a direct path from containment atmosphere to the outside.
| |
| 4
| |
| '2. Radiation levels in fuel handling areas, the containment and the spent fuel storage pool areas-shall be monitored continuously.
| |
| : 3. The core suberitical neutron flux shall be continuously monitored by I
| |
| at least tw'o neutron monitors, each with continuous visual indication i
| |
| in the control room and one with audible indication in the containment, l which are in service whenever core geometry is being change.d. When core geometry is not being changed, at least one neutron flux monitor shall be in service.
| |
| ,i j 4. During reactor vessel head removal and while loading and unloading i
| |
| fuel f rom the reactor, the minimum boron concentration of 2000 ppm ''
| |
| shall be maintained in.the. reactor coolant system. The required boron concentration shall be verified by chemical analysis daily.
| |
| '5. During movement of fuel assemblies or control rods out of the reactor
| |
| * vessel, at least 23 feet of water shall be maintained above the reactor vessel flange. The required water level shall be verified prior to moving fuel assemblies or control rods and at least once
| |
| ; every day while the cavity is flooded.
| |
| : 6. At least one residual heat removal ~ pump shall be operable and- running.
| |
| The pump may be shutdown for up to one , hour to facilitate movement of fuel or core components.
| |
| : 7. If the water level above the cop of the reactor vessel flange is less i
| |
| i than 20 feet, except for control rod latching and unlatching operations, both residual heat removal loops shall be operable.
| |
| ! 8. If Specification 3.8. A.6 or 3.8. A. 7 cannot be satisfied, all fuel handling operations in containment shall be suspended, the contain-ment, integrity requirements of~ Specification 3.8.A.1 shall be satisfied, and no reduction in reactor coolant boron concentration shall be made.

| |
| i - Basis The equipment and general procedures to be utilized during refueling are dis-cussed in-the FSAR. Detailed instructions, the precautions specified above, and the design of the fuel handling equipment incorporating built-in inter-locks and safety features, provide assurance that no incident could occur during the and safety.(({ueling operations Whenever changes that are would result not being in in made a hazard to publicone core geometry, health flux l monitor.i.s sufficient. This permits maintenance of the instrumentation. Con-tinuous monitoring of radiation levels (B above) and neutron flux provides immediate indication of an unsafe condition. The residual heat ccmoval pump
| |
| . is used to maintain a uniform boron concentration.
| |
| The shutdown margin indicated in A.S. above will keep.the core subcritical, even if all contiol rods were . withdrawn from the core. During refueling,-the reactor refueling cavity is filled with approximately 275,000 gallons of' borated water. The boron concentra ion of this . water is sufficient to maintain the reactor auberitical by approximately 10% ak/k in the cold condition with all rods inserted, and will also maintal rodswereinserted'intothereactor.i2yhecoresuberiticalevenifnocontrol Periodic checks of refueling water boron concentration insure that proper shutdown margin is maintained. A.6.
| |
| above allows the control room operator to inform the manipulator operator of any impending unsafe condition detected from the main control board indicators during fuel movement.
| |
| No movement of fuel in the reactor is permitted until the reactor has been
| |
| , subcritical for at least 100 hours to permit decay of the fission products in the fuel.
| |
| l analysis.(3Jhedelaytimeisconsistentwith,thefuelhandlingaccident-The spent fuel assemblies will be loaded into the spent fuel cask for shipment toareprocessingplantaftersufficientdecayoffissionpropggts. In loading the cask into a carrier, there is a potential drop of 66 feet The cask will not be loaded onto the carrier for shipment prior to a 3-month storage period. At this time, the radioactivity has decayed so that a release of fission products from all fuel assemblies in the cask would result in off-site doses less than 10 CFR Part 100. It is assumed, for this dose' analysis that-12 assemblies rupture after storage for 90 days. Other assumptions are the same as those used in the dropped fuel assembly accident in the SER, Section 15.
| |
| The resultant doses at the site boundary are 94 Rems to the thyroid and 1
| |
| ; Rem whole body.
| |
| The Spent Fuel Pool Special Ventilation System is a safeguards system which maintains a negative pressure in theispent fuel enclosure upon detection of high area radiation. The Spent Fuel Pool Normal Ventilation system is auto-4 matica11y isolated'and exhaust air is drawn through filter nodules containing I
| |
| a roughing filter, particulate filter, and a charcoal filter before discharge ~
| |
| to the environment via.one of the Shield Building' exhaust stacks. Two completely redundant trains are provided. The exhaust fan and filter of each train are shared with the corresponding train of the Containment In-service Purge System.
| |
| High efficiency particulate absolute (HEPA) filters are installed before the charcoal adsorbers to prevent clogging of ,the iodine adsorbers in each SFPSVS filter train. The charcoal adsorbers are installed to reduce the potential /

| e TS.3.8-4 REV release of radioiodine to the environment. The in place test results should indicate a HEPA filter leakage of less than 1% through DOP testing and a charcoal adsorber leakage of less than 1% through halogenated hydrocarbon testing. The laboratory carbon sample test results should indicate a radio-active methyl iodide removal efficiency of at least 90% under test conditions which are more severe than accident conditions. The satisfactory completion of these periodic tests combined with the qualification testing conducted on new filters and adsorber provide a high level of assurance that the emergency air treatment systems will perform as predicted in the accident analyses.
| |
| During movement of irradiated fuel assemblies or control rods, a water level of 23 feet is maintained to provide sufficient shielding.
| |
| The specifications require that at least one residual heat removal loop be in operation. This assures that sufficient cooling capacity is available to ccmove decay heat and maintain the water in the reactor below 140*F and that sufficient coolant circulation is maintained through the core to mini-mize the effect of a boron dilution incident and prevent boron stratification.
| |
| The requirement to have two residual heat removal loops operable when there is less than 20 feet of water above the vessel flange ensures that a single failure of the operating loop will not result in a complete loss of residual .
| |
| heat removal capability. With the reactor vessel head removed and 20 feet of water above the vessel flange, a large heat sink is available for core cooling. In the event of a failure of the operating RRR loop, adequate time is provided to initiate repairs or emergency procedures to cool the core.
| |
| The water level may be lowered to the top of the RCCA drive shaf ts for latching and unlatching. The basis for this allowance is (1) the refueling cavity pool has sufficient level to allow time to initiate repairs or emergency procedures to cool the core (2) during latching and unlatching the level is closely mon-itored because the activity uses this level as a reference point. (3) The time spent at this level is minimal.
