6 3,0 Basis for the Revision

[ Items C, I, M] The changes add commitments to specific sections of applicable industry codes and standards for the process building cranes. The commitments associated with process building cranes are now consistent with the code commitments associated with liquid UF. cylinder y

I handling cranes. These commitments involve inspection and testing requirements. As discussed in i

the October 31,1997 SARUP submittal, certain process building cranes (those that move heavy loads above/around cascade equipment that is intended to be operated above atmospheric pressure) are classified in the SARUP as AQ SSCs Consistent with this change in quality classification was a commitment to identify industry codes and standards to would apply to these cranes. This revision to S ARUP fulfills that commitment.

[

t I

[ Item D) The change to SARUP Chapter 1, Appendix A, Section 1.15 corrects the year of record for ANSI B30.20 from 1992 to 1993,

[ Item E] The change to SARUP Section 3.8.2.2.3 is made to incorporate modifications described in the original October 31,1997 SAR Update submittal (Reference 1 - Enclosure 1. Table 1, item 11). The installation of these handswitches at the building exits in Building X-342-A provides additional assurance that operators will be able to initiate UF line isolation in the event of a UF 6

6 l

release.

[ Item F] This change revises wording in S ARUP Section 3.8 to remove reference to S ARUP Chapter 1, Appendix A, for liquid UF handling cranes. The sections of the codes and standards 6

referenced in Chapter 1. Appendix A. are inspection and testing requirements and not design requirements. There are no changes to the commitments to sections of crane codes and standards in SARUP Chapter 1, Appendix A.

[ Items G, K, N,0, P] These changes incorporate the results of a new hydraulic performance study of the fire protection sprinkler system. The new study concluded that for the worst case process building fire the maximum sprinkler head flow demand would be 3629 gpm rather than the 2500 gpm assumed in the original S ARUP analysis. As explained in the original October 31,1997 S ARUP submittal (Referene: 1 - Enclosure 1, Table 1, item 10), the original S ARUP analysis was l

based on an earlier hydraulic study performed for PGDP. Other related changes are also identified, including the required sprinkler head operating area and water tank consumption. The study did not require changes to essential controls nor were changes to TSR LCOs required since the new flow rate f

GDP 98-0212 Page 4 of 4 was still within the operating envelop of a single HPFWS pump. Minimum required tank levels (water and diesel fuel) specitied in the TSRs are also not atTected by the results of this study since they were conservatively based on pump operating capacities and run times (which were not atTected by the study) and not the maximum required sprinkler tiow. This change is conservative in that the required flow rate is being increased and the accompanying surveillance requirement change for the HPFWS pumps will ensure that the new flow rate is met.

[ Item H] The change to SARUP Section 3.8.10.1.2 is made to delete the reference to the ERP station in the AQ-NCS boundary discussion of the high pressure venting system since this system is not credited in the corresponding NCSA.

[ Item J] The change to SARUP Appendix 5.2A is made to include a reference to dry ice l

blasting as a means to decontaminate equipment and facilities is consistent with other field dry decontamination techniques currently addressed in the SAR. Worker protection is accomplished l

during this activity by use of personal protective equipment consistent with the airborne levels present.

l

[ Item L] The change to TSR Section 2.1.3.6 is made to clarify in the Basis section actions that are already addressed in the Limiting Condition for Operation, Required Action D.2, i.e., that I

draining the RCW from the coolant condenser also precludes the potential for introducing moderation (RCW) to the process system.

[ Item Q] The change revises the Basis statements for SARUP TSR Sections 2.2.4.2 and 2.3.4.2 to remove one of two references to S ARUP Chapter 1, Appendix A, for liquid L% handling cranes. The sections of the codes and standards referenced in Chapter 1, Appendix A, are inspection

. and testing requirements and not design requirements. The discussion preceding the deleted reference involved design guidance. There are no changes to the commitments to sections of crane codes and standards in SARUP Chapter 1, Appendix A.

O Remote switches shall be located where operator action can be accomplished upon evacuation of the facility.

3.8.2.2.3 System Evaluation The remote feed isolation system was evaluated to assess its ability to accomplish its required safety function. A fault tree analysis was performed to determine the system's capability to meet the safety function.

l The results of the evaluation are provided in this section.

Safety function analysis. The safety function required of this system is to limit the quantity of UF.

released to less than the radiological and nonradiological EGs for the EBE category. A review of facility I

operations determined that pigtail /line failure outside autoclave event is the limiting event for this system (see Section 4.3.2.2.10). Specifically, two scenarios could result from this initiating event: (1) rupture of a feed line while feeding a cylinder to the cascade and (2) failure of an evacuation header while heeling a cylinder.

For both scenarios, operators in the facility are capable of detecting the release. For significant releases of

(

UF., visual detection of the release is easily accomplished due to the reaction products forming smoke.

i For each scenario, a rupture in a feed line while feeding a 14-ton cylinder to the cascade results in the worst-case gaseous release (see Section 4.3.2.2.10). The requirements for this system are to provide the capability to isolate the lines within a 30-second time frame after actuation of the system and have accessibility for the operators to actuate the system. Operator response to the event is addressed in Section 4.3.2.2.10.

As indicated in the system description (see Section 3.2.1.1.1), the system can isolate the required valves to perform the required safety function. The environmental conditions associated with this circuitty is not significantly different, other than the " smoke" generated from the reaction of UF. and the moist air, than O

normal operation due to the required response time and the operator. For an evaluation of the remaining functional requirements, see the qualitative fault tree analysis below.

Based on the operator presence in the facility for these types of releases, the remote feed isolation system can accomplish the required safety functions and prevent exceeding the EBE EGs for the facility.

- Qualitative fault tree analysis. In addition to the safety function analysis, a qualitative fault tree analysis was performed in accordance with Section 4.3.1.1.3. The fault tree analysis concluded that the i

I system can meet the functional requirements described previously, with the exception of being independent of 120-VAC power for the facility. However, some discussion of the specific configuration is warranted.

i In X-342 A, the handswitches (4 in number) for the system are located at the following locations:

l 1.

One at the feed con' ol panel in the high bay area.

l 2.

One inside the Fluorine Control Room.

l' 3.

One at the North East exit door on the outside wall.

l 4.

One at the South Center exit door on the outside wall.

In X-343, the handswitches for the system are located in the control room. Surveillance requirements for these handswitches require periodic operability testing.

SAR. PORTS PROPOSED October 19,1998 RAC 97-X0506 (RO), RAC 98-X0130 (RO) for the EBE frequency category if a release were to occur. [A threshold analysis indicated that, in all cases, it takes more than 500 lb (227 kg) to exceed the 30-mg U dose at the site boundary (all cases that exceeded this dose were greater than 1000 lb (454 kg) of UF.l.

Cylinders that are not approved (i.e. sized) for holding greater than 500 lb (227 kg) of UF. do not have the capacity to contain sufficient material to result in significant off-site health effects.

Cylinders capable of holding greater than 500 lb (227 kg) of UF. but not approved for tilling may contain only solid UF. unless they are being heated in a closed autoclave.

Cylinders containing only gaseous / solid UF., regardless of size, have the potential to exceed only the on-site EGs if the cylinder does not maintain its integrity.

Therefore, cylinders capable of holding more than 500 lb (227 kg) of UF. are classified as Q. Smaller cylinders (capable of holding no more than 500 lb [227 kg] of UF.) are classitled as AQ.

3.8.6.1.5 Boundary ne Q and AQ boundaries for the UF. cylinders are defined in Tables 3.8-1 and 3.8-2, respectively.

3.8.6.2 Liquid UF. Cylinder Handling Cranes ne liquid UF. cylinder handling cranes consist of those cranes and associated lifting tixtures in the feed, withdrawal, and toli enrichment services facilities that are used to lift liquid-tilled UF. cylinders.

3.8.6.2.1 Safety Function The liquid UF. cylinder handling cranes shall not fail in a ' manner to cause UF. primary system integrity failure. The liquid UF, handling cranes provide for the safe movement of liquid UF cylinders.

This function is accomplished by assuring liquid UF. handling crane lifting components and load braking systems are maintained to prevent an uncontrolled dropping of a cylinder.

SAR-PORTS PROPOSED October 19,1998 RAC 97-X0506 (RO), RAC 98-X0130 (RO) 3.8,6.2.3 System Evaluation The required safety function is to not fail in a manner that causes UF. primary system failure (i.e.,

dropped cylinder) during normal operation, an evacuation of facility event, or natural phenomena events. The l cranes are designed for the loads they will handle during normal operation of these facilities. Administrative controls require inspections of the cables, brakes, and other critical items to ensure that the crane can operate l correctly (refer to Chapter 1, Appendix A, for commitments to ANSI standard inspection and testing l requirements). In addition, the cranes are designed so that when the controls are released (e.g., evacuation of facility event), some small additional movement occurs due to momentum after the crane drive mechanism l

stops and brakes are applied but these movements have no safety signiticance. The cranes were evaluated to l

assess their ability to withstand natural phenomena events. The analyses indicated that the cranes will not have any structural damage, will remain in place, and will not release their loads during an evaluation basis l

earthquake and wind, with the exception of the Building X-343 crane under high wind loading. As evaluated I

in Section 4.3.2.5.2, a failure of the X-343 building is postulated under high wind loadings, and the building l

structural failure could result in the crane releasing its load. Floods do not reach the elevation of the facility I

to threaten crane integrity.

Failure of the crane litling components or load braking system while lifting liquid-tilled UF. cylinder l

could result in dropping the cylinder and rupturing the cylinder. Therefore, a load test is performed periodically.

p Based on the analysis, the cranes can accomplish the required safety function, with the exception of

\\

j the crane in X-343.

l 3.8.6.2.4 System Chtssification l

The liquid UF. cylinder handling cranes are required to perform the following safety function:

l l

Prevent dropping a liquid-filled cylinder that could result in a cylinder failure event.

The cylinder failure event is classitied as an EBE whose consequences could exceed the off-site EGs if the cranes were to fail in a manner that resulted in the drop and failure of a liquid-tilled cylinder.

Therefore, the liquid UF. handling cranes meet the criteria for classification as a Q system.

The Q boundaries for the liquid UF. cylinder handling cranes, including associated lifting t1xtures, are defined in Table 3.8-1.

3.8,7.2.3 System Evaluation Automatic sprinkler systents. An unmitigated tube oil fire in Buildings X-326, X-330, or X-333 l could lead to significant consequences for on-site personnel. Similarly, an unmitigated tire in X-343 could lead J

to significant consequences to onsite personnel. Based on the credible tire scenarios and an analysis of unmitigated tire effects, operator action cannot be solely relied upon to prevent or mitigate large tires.

Therefore, the automatic sprinkler systems protecting these buildings are required. The, vater used by the l sprinkler systems is supplied by the high pressure tire water system (HPFWS). This system has a gridded l distribution piping network, several tire water pumps, and an elevated storage tank.

l For PORTS, a hydraulic effectiveness study was performed for the existing sprinkler systems of the l X-333, X-330, and X-326 process buildings.

l cell and operating floors are used to define the evaluation basis fire demand.

The total water l consumed in 30 min at this rate would be approximately 109,000 gal, which corresponds to about forty percent of the capacity of the X-640-2 elevated storage tank.

The water-level drop in the tank for this water l consumption is estimated to be 10.4 ft, which corresponds to a pressure reduction of 4.5 psi. The HPFWS l fire water pumps each have a capacity that exceeds the 3629 gpm highest tire water tiow rate, I

The process building cranes shall not fail from the parked position in a manner that will cause UF.

primary system failure during an evaluation basis natural phenomena event.

%e process building cranes shall be designed to prevent dropping of the load should the controls be released for any reason (e.g., evacuation of the facility).

l-The process building cranes shall be designed for the loads they will handle during operation of these facilities.

3.8.9.2.3 System Evaluation The process building cranes are required to be designed so that evaluation basis natural phenomena events will not result in a large release of UF. when the cranes are in the parked position. This safety function is accomplished by requiring the cranes to withstand evaluation basis natural phenomena events to the extent necessary to prevent failure of the UF. primary system. The process building cranes are parked in a standby location when not in use. There is one crane in Building X-333 that is normally parked over unit bypass piping. Analysis indicates that this process building crane will not fall from its parked positions during an evaluation basis earthquake, and it is not affected by the evaluation basis thn! or high wind events. The use p

of the building cranes for moving a heavy load is infrequent because they are only needed when a piece of U

major equipment must be replaced. They are also used for other infrequent tasks such as replacing lights.

Thus, the moving of a heavy load with a crane or the use of a crane for other activities concurrent with an evaluation basis natural phenomena event is not considered a credible event.

The process building cranes are also required to be designed so that a large release of UF. will not occur during an evacuation of the cascade process building (see Section 4.3.2.1.5) due to a release of the manual controls. This safety function and associated functional requirement are accomplished by the cranes being designed to not allow the load to be dropped after the operator moves the crane to his egress location and releases the controls. In addition, only small compensatory movements (to prevent the load from swinging) occur upon a release of the crane controls.

The other functional requirement is accomplished sirice the process building cranes were originally designed for the loads they will handle during operation of these facilities and their design capacities are maintained in accordance with the rated capacities.

l l

Re assurance of crane operability is provided by ongoing inspections and tests (refer to Chapter 1, l

l Appendix A, for commitments to ANSI standard inspection and testing requirements). Failure of the crane lifting components or load briking system while lifting heavy loads could result in tu dropping of the load and i

a subsequent rupture of the UF. primary system piping inside the process building (see Section 4.3.2.1.8).

In order for a criticality to be possible, multiple contingency events would need to occur simultaneously. For instance, U-235 accumulating in the washer over a number of wash cycles is an unlikely event since there are no tilters or traps on the washer and since there are multiple water reloads per wash cycle which tend to flush away possible pockets of accumulation. Also, prior to washing PPE, the laundry bags are measurnt with a gamma radiation detection instrument, if the sum of all measuremenn for bags is less than the est shed limit, the bags may be washed in one or more washer. Therefore, the double contingency principle is met by one unlikely event and one administrative control.

There are no AEFs identified for the laundry facility.

7.16 Cylinder Valve Replacement UF. cylinder valves occasionally need to be replaced due to some form of malfunction (plugged, seized, etc.). The cylinder may be partially or entirely filled with solid UF. at the time of the replacement.

A number of administrative controls are in place to prevent criticality, such as maintaining plugs readily available during the operation. The plugs are used in the event that neither of the two replacement valves can be installed after removal of the old valve. Administrative controls require the replacement valves be prepared and ready for installation. Administrative restrictions limit the number of used cylinder valves that can be grouped together for storage or transport. The primary criticality controls for UF. cylinder replacement are mass, enrichment, moderation and interaction.

qQ in order for a criticality to be possible, multiple contingency events would need to occur simultaneously. For instance, if more than the permitted number of used cylinder valves are gathered together in a group (violation of an administrative control), a spacing requirement between groups is maintained.

Additionally, a passive barrier limits the internal free volume of the cylinder valve. All of these requirements prevent a criticality from occurring. 'lherefore, the double contingency principle is met and there are no AEFs identified for the UF. cylinder valve replacement operation.

7.17 Building Decontamination Activities.

A number of decontamination activities are routinely conducted in support of building operations.

Field decontamination is conducted in order to safely and expediently remove potential health hazards, to recover uranium material so that it may be recycled back into the enrichment process, and to prepare 35 equipment for repair or discard. Because uranium-bearing materials enriched in U: may be present on the surfaces to be decontaminated, decontamination activities have the potential to generate unsafe quantities of 2

U ". Decontamination activities generally fall into two categories: dry and wet.

Dry decontamination comprises the removal of contamination through mechanical action on contaminated compounds with brushes, rags, shovels, dry vacuum cleaners, strip coat, dry ice and other blasting, etc. Dry decontamination using bmshes, shovels, and other non-vacuum equipment is generally used outside of containment enclosures only when necessary due to the potential for generating airborne particulates.

Any of the dry decontamination methods can be performed in negative pressure containment enclosures erected to minimize the potential for generating airborne particulates.

SAR-PORTS PROPOSED October 19,1998 RAC 97-X0314 (RI), RAC 98-X0037 (RO)

Wet decontamination involves the removal of contaminated compounds through dissolution, l suspension, or absorption using rags, sponges, mops, wet vacuum cleaner, steam jennies, etc. Wet decontamination may result in the generation of solutions, suspensions, or slurries containing contaminated material.

The nuclear criticality safety of building decontamination operations is based on the control of mass, moderation, enrichment, volume, geometry, and interaction. Administrative controls and passive barriers have been incorporated to prevent a criticality from occurring. Enrichment is controlled as part of the operation requirements. Geometry controls for decontamination solids are used to limit depth of floor sweepings and container sizes. These controls also include use of funnels. Interaction contrels require administrative spacing limits to specify uranium bearing solid and liquid decontamination waste container and equipment interaction.

I l

In order tbr a criticality to be possible, multiple contingency events would need to occur simultaneously. For instance, where favorable geometry is not relied upon, NCS controls prevent the l

accumulation of greater than a safe mass by, for example, the requirement for no visible contamination when cleaniag up mercury spills. This requirement makes it unlikely that gieater than a safe mass will be vacuumed up into the vacuum cleaner. In addition to the margin between the safe mass and minimum critical mass, a second control is provided to prevent moderation of the material in a vacuum. This requirement is that i

mercury spills where no water or other forms of moderation are present are allowed to be cleaned up with a vacuum cleaner. It is not credible that a minimum critical mass of uranium-bearing material would be vacuumed up since no visible uranium is allowed to be vacuumed.

Double contingency is met and there are na AEFs identified for building decontamination activities.

4 l

assemblies are removed from compressors in the process buildings, temporarily stored in barrier cages, vaults, or lockable rooms in the process buildings, and sent to X-705 for decontamination. Also, seal assemblies may be removed from the compressors after the entire compressors are sent to X-705. Seal assemblies to be cleaned are disassembled in the seal dismantling room.

Admmistrative controls are in place to prevent criticality during the handling and storage of seals and seal cans. These administrative controls impose limits on mass, enrichment, moderation and interaction. The mass of U " is controlled both by the limited size of the seals' void spaces and by prohibiting visible 2

contamination on any seals put in a seal can or on classified seal parts disposed of in 55-gallon drums.

Enrichment of material in seals that are handled as described here is limited. Moderation is controlled by prohibiting the introduction of moderating materials into seal cans. Interaction is controlled by limiting the number of seal cans that may be grouped together and limiting the minimum spacing between seal can groups and other uranium-bearing materials.

The fire protection system is provided to mitigate a tube oil fire that could cause a potential threat to primary system integrity with the potential for onsite and offsite consequences. The High Pressure Fire Water System (HPFWS) is divided into three areas: (1) the HPFWS pumps; (2) the HPFWS cascade building sprinklers; and (3) the HPFWS elevated water storage tank.

The sprinkler system provides primary fire suppression capability for the areas in which they are installed.

l The sprinklers are designed to extinguish a lube oil fire by providing approximately 3700 gpm tivough the sprinkler heads onto a tire. 'Ihe elevated tire water storage tank and HPFWS pumps provide the pressure and water to the sprinkler heads.

The sprinklers detect a fire and actuate through the use of a temperature rated sprinkler head.

SR 2.1.4.1-2 Verify crane hoist does not allow load to move (except for Biennially compensatory movements) upon operator release of the controls while at a minimum of 100% of rated capacity.

BASIS:

The process building ccanes on the cell tloor consist of the overhead bridge cranes and associated equipment in the enrichment facilities and the withdrawal'.acilities. The process building cranes shall not fail in a manner

[]

to cause primary system integrity failure durir g: (1) normal operation; (2) natural phenomena events with the V

cranes in the parked position; and (3) an ev teuation event due to a release of crane controls. These safety functions are passive in nature (i.e., no active cimponents required of the system). The movement of a heavy load with a crane is infrequent. Thus, the mo 'ement of a heavy load with a crane concurrent with a natural phenomena event is not considered a credible event. The assurance of crane operability is provided by the SURVEILLANCE REQUIREMENTS. In addition to the surveillances specified above, cranes handling heavy equipment as described in this DF are inspected and tested in accordance with sections of applicable industry standards as described in the SAR Chapter 1, Appendix A. Compensatory movements are small additional movements due to momentum after the crane drive mechanism stops and brakes are applied. These compensatory movements have no safety significance.

l compressor surging, line recorders, stage control valve positions, A-suction pressures, etc.). Since larger wet l

air inleakages announce themselves readily, and continuously tiuorinated UO F deposits of any magnitude 2

pose no criticality safety concern, a quarterly surveillance for UO F deposits is appropriate for early detection 2 2 of such deposits and followup surveys for prudent remediation.

l Once identified, the growth of a deposit is monitored quarterly to assure that the deposit does not become sutticiendy large to become an operational problem or a cascade structural concern. The maximum allowable size of the deposit is primarily dependent on its location and will be determined as a part of the surveillance of the deposit. Operational experience suggests that quarterly surveillance by NDA methods is adequate to monitor the size of the deposit in process piping, expansion joints and valves. NDA is of limited value (e.g.,

quantification of deposit size) for compressors, converters, process gas coolers and freezer sublimers. The size of a deposit in a freezer sublimer can be determined by the remaining weight when the F/S has been l

emptied of UF.. Deposits in axial and centrifugal compressors are detected by the damage the deposits cause to the impeller or by deblading. Deposits in the converters are determined by the impact of the deposit on the pressure drop across the converter. Deposits in the process gas cooler are identitled by the operator as degraded performance and are located by radiation surveys.

l For shutdown cells, moderation control can also be provided by a dry gas (plant air or nitrogen) blanket over l

the deposit. Once a system has been isolated from the cascade and tilled to 2 14 psia with a dry gas blanket, normal atmospheric pressure fluctuations will cause minor in and out flow through any existing system leaks.

(

Analyses have demonstrated that this " breathing" of the cell will n't signiticantly affect deposit moderation, l

even over a period much longer than the 180 days to which this condition is limited. The daily surveillance l

demonstrates that the gas blanket is maintained as assumed in the analyses.

The potential for moderation from RCW system water is precluded by the two physical barriers (RCW to coolant and coolant to cascade) and either by maintaining the coolant system pressure greater than the RCW pressure or by draining the coolant condenser. [SAR Section 5.2, Appendix Al l

BASIS:

He HPFWS X-640-2 storage tank is designed to supply sufficient pressure to provide flow through the building sprinklers.

De accident analysis for a large fire in the cascade facilities requires a tiow period of 30 minutes. Makeup to the elevated tank comes from the one or more of the six HPFWS pumps, of which four are designed to start segaentially as the elevated tank level declines.
