Docket No. 70-7002 Certificate Amendment Request - Update the Application Safety Analysis Report - Proposed Changes
Dear Dr. Paperiello:
By letter dated October 31,1997 (Reference 1), USEC submitted a certificate amendment request containing the Safety Analysis Report Update (SARUP) required by Issue 2 of DOE /ORO-2027,
" Plan for Achieving Compliance with NRC Regulations at the Portsmouth Gaseous Diffusion Plant,"
(the Compliance Plan) for NRC review and approval. USEC's October 31,1997, letter contained the following commitment:
In the absence of fire loading analyses, the DOE SAR Upgrade (POEF-LMES-89) assumed that a large fire is possible in the X-342-A and X-344-A feed vaporization facilities.
Consequently, the SAR Update includes these fire scenarios, classifies the fire suppression systems in these areas as AQ, and applies TSRs. (Note that the current accident analysis in the Application SAR states that the combustible loading in these facilities is not sufficient to support a large fire that would threaten UF. containment.)
USEC has initiated a combustible loading analysis to determine if the fire suppression systems in X-342-A and X-344-A can be downgraded to non-safety. If the combustible loading in these facilities is found to be sufficient to support a large fire, modifications will I
be proposed to these fire suppression systems consistent with its AQ classification and TSRs.
However, if the combustible loading is determined to be insufficient to support a large fire,
\\
the SAR Update will be revised to modify the scenarios, reclassify the suppression systems as non-safety, and delete the TSR requirements. The results of the USEC combustible loading analysis, including any necessary changes to the SAR Update, will be submitted to the NRC by March 23.1998 9805080007 980430 PDR ADOCK 07007002 C

April 30,1998 GDP 98-0096, Page 2 By letter dated March 19,1998, USEC revised the above commitment to indicate a submittal date of April 30,1998.
In accordance with this commitment, the combustible loading analysis of the X-342-A and X-344-A
)
buildings has been completed and has determined that an unmitigated fire in either of these facilitjes would not (1) compromise the integrity of the UF primary systems or a cylinder containing UF. and i
result in a release that exceeds offsite Evaluation Guidelines or (2) threaten the structural steel or steel roof decking to cause collapse of these buildings. Consequently, the fixed fire suppression i
sprinkler systems within the X-342-A and X-344-A buildings and the sanitary and fire water system (SFWS), including its distribution and elevated storage tank, can be eliminated as AQ systems from the SAR Update submittal. to this letter provides a detailed description of the proposed changes. Revised SAR Update pages associated with this submittal are provided in Enclosure 3. Revisions to the material originally submitted with the October 31,1997, SAR Update submittal are noted by a revision bar in the left-hand page margin. In addition to these revised SAR Update pages, a revised revision log and a list of effective pages for the SAR Update submittal are also included in Enclosure 3. The conclusions stated in Enclosure 2 to Reference 1, that the propcsed changes associated with the CAR are significant, are not affected by this revision and thus no significance determination is provided.

Proposed Changes Certificate Amendment Request Update the Application Safety Analysis Report Detailed Dr cription of Change 1.0 P_urpose The purpose of this update is to provided revised pages to the Safety Analysis Report Update (SARUP) previously transmitted in USEC letter GDP 97-0189, dated October 31,1997, forNRC review and approval.
The purpose of the proposed revisions are to remove the fixed fire suppression sprinkler systems within the X-342-A and X-344-A facilities and the sanitary and fire water system (SFWS),
including the distribution and elevated storage tank, as AQ systems from SAR Update. The proposed changes are the result of a combustible loading analysis of X-342-A and X-344-A facilities which determined that an unmitigated fire in any of these facilities would not (1) compromise the integrity of the UF primary systems or a cylinder containing UF and result in a 6
6 release that exceeds Evaluation Guidelines off site or (2) threaten the structural steel or steel roof i
decking to cause collapse of these buildings.

systems for buildings X-342-A and X-344-A and the sanitary and fire water system as AQ safety systems as a result of a fire hazard assessment of these facilities. The assessment was not available prior to the initial SAR Update CAR submission. The assessment provided documentation that an unmitigated fire in these facilities would not (1) compromise the integrity of the UF prirnary j
6 systems ~or cylinder containing UF and result in a release that exceeds Evaluation Guidelines off site 6
or (2) threaten the suuctural steel or steel roof decking to cause collapse of these buildings. The end l
result is the SAR Update CAR does not credit the sprinkler systems or sanitary and fire water system t
for any safety function.

'Iherefore, the automatic sprinkler systems potecting these buildmgs are required. The water used by the l sprinkler systems is supplied by the high pressure fire water system (HPFWS). This system has a gridded l distribution piping network,'several fire water pumps, and an elevated storage tank.
For PGDP, a hydraulic effectiveness study was performed for the existing sprinkler systems of the cell floors in the C-331 and the C-333 type buildings, and the operating floor in C-331. The calculated minimum and average available densities were identified. The existing sprinkler systems can provide an average density greater than required by NFPA 13 (as described in Chapter 1, Appendix A). Available sprinkler discharge densities for the cell floor in Buildings C-310 and C-315, and the operating floor in Buildings C-310, C-315, C-333, C-335, and C-337 have not been reported, but analyses of the hydraulic effectiveness of the sprinkler systems in these buildings indicate that the systems are adequate. No corresponding calculations have been made for PORTS process buildings. However, because the process buildings and the associated sprinkle systems at PORTS and PGDP are similar, the minimum and average available densities are assumed to 1 e applicable to the process buildings at PORTS as well.
High pressure fire water system.
Buildings X-326, X-330, X-333 and X-343 are on the HPFWS.' The system design basis considers a sprinkler operating area slightly under 6000 ft (557 m ) for 2
2 l
a lube oil spill fire on the cell (second) floors in the process buildings. For the operating (ground) floors, the maximum sprinkler operating area was determined to be 8400 ft (780 m ). These sprinkler operating 2
2 areas for the cell and operating floors are used to define the evaluation basis fire. The highest average fire water flow rate for the evaluation basis fire is estimated to be 0.30 gpm/ft x 8400 ft = 2500 gpm (9.5 2
2 m'/ min) for the operating floor. The total water consumed in 30 min at this rate would be 76,000 gal (290 m'), which corresponds to about one fourth of the capacity of the X-640-2 elevated storage tank. The water-level drop in the tank for this water consumption is estimated to be 6.7 ft (2.0 m), which corresponds to a pressure reduction of 2.9 psig (120 kPa). The HPFWS fire water pumps each have a capacity that 3
l exceeds the 2500 gpm (9.5 m / min) highest average fire water flow rate.

Cylinders to be filled with UF are verified as passing a current (within 5 years) hydrostatic pressure test; 6.
Cylinders containing liquid UF. are staged in a designated area until solidified (this area is restricted so thu routine vehicle traffic is not allowed - vehicles are allowed for certain maintenance evolutions); and 7.
UF cylindes to be filled or heated are inspected for obvious damage that could threaten their ability to withstand normal filling, heating and moving.
UF. cylinder high temperature steam cutoff system - maintain initial condition (normal operation,
=
EG S only);
Liquid UF handling cranes - maintain primary system integrity (EGs 1 and 2); and l
Operator training for required actions - evacuate area of releases (EGs 1 and 2 only).
Based on the above essential controls, the resulting important to safety SSCs and TSRs are as follows:
The UF. cylinder high temperature steam cutoff system and liquid UF handling equipment (cranes, scale carts, nilcars) are identified as important to safety SSCs. See Section 3.8 for details including safety classification.

ScenariDJDcScription During operations associated with withdrawal, feed, toll transfer, sampling, and cylinder hand!ing and storage operations, the potential exists for fires to occur. Small fires can be caused by welding and burning operations, electrical failures, vehicle accidents, etc. The withdrawal operations are performed I
in the process buildings that house lube oil and the associated fire-related concerns are addressed in the j
large fire scenario for the cascade facilities (see Section 4.3.2.1.9).

l The X-343 facility does not contain any significant quantities of flammable or combustible l materials. Additionally, this facility is provided with a fixed fire suppression system to prevent a fire large enough to threaten primary system integrity. Therefore, the hazards analysis did not consid:r a large fire l to be credible for the X-343 facility.
l The X-342-A and X-344-A facilities do not contain any significant quantities of flammable or l combustible materials. An assessment of these facilities concluded than an umnitigated fire would not l compromise primary system integrity or result in a release of UF. In addition, an unmitigated fire will 6
l not threaten the structural steel or the steel roof decking to cause collapse of these buildings. The l
l assessment did not credit the sprinkler systems or manual fire fighting capabilities for these facilities.
The cylinders in storage yards are exposed to combustible materials (i.e., fuel) from the equipment used in the cylinder handling / storage operations. If a large fire occurs in the cylinder storage yards, it has the potential to liquefy the contents of a cylinder to the point where the cylinder could hydraulically rupture. This cylinder rupture due to a large lire co"Id result in a significant UF. release. The only mitigation source provided for large fire event in the cylinder storage yards is the on-site fire department.
The plant Fire Protection Frogram (which includes the on-site fire department) is described in Section 5.4 and provides a high degree of protection against fires that could occur within the cylhTder 4.3-126 l

The essential controls for this event are no different with the added requirement for the on-site fire department. Therefore, no additional consequences are addressed.

Comnarien wah c.nia.iino.
The comparison with guidelines will be subdivided to address the different receptors.
Local workers in the immediate area - Because of the time that lapses before a fire becomes large, workers in the immediate area of the release could easily evacuate the area prior to being exposed to any h
release. Therefore, no specific requirements are associated with the local worker.
Workers outside the process buildings - The essential controls for protecting on site personnel outside the facilities are (1) detection of the fire and/or release (both worker and operator) and (2) training of on-site personnel to evacuate areas upon detection by sight or odor. The first essent al action ir to detect i
the fire and/or release of UF..
If workers outside of the process building have received no other instructions for action to be taken (i.e., shelter in place or take cover), then the essential control for these receptors is to evacuate their areas if a release is detected by sight or by odor. As indicated in the consequence analysis, on-site consequences could exceed 30 mg U out to about 900 ft (275 m) for the initial release if no mitigative actions were taken.
Of-sitepublic - As indicated in the consequences section, the consequences for this event could vary over a wide range due to the various parameters. The essential controls for mitigation of this event are bounded by the cylinder failure outside autoclave scenario described in Section 4.3.2.2.15 with the added control of the on-site fire department.
e.
Summarv or SSC_and TSR Controls Based on the results of this analysis, the essential controls for this event are summarized as follows:
Administrative controls to prevent a large fire-maintain initial condition (normal operation. EG 5 only);
1.
Presence and introduction of flammable and combustible materials in the cylinder yards is controlled by approved procedures; 2.
Daily inspection (when used) of cylinder handling equipment for obvious visual defects associated with the lifting system and potential fuel / hydraulic leaks; 3.
Communication capability between the cylinder handling operators and with the fire department / emergency response personnel is available; 4.
Only approved cylinder handling equipment is used by qualified operators for maneuvering UF, cylinders or other heavy loads; 5.
Operator training for required actions; 6.
Fire Protection Program (which includes on-site fire department).
l Fixed fire suppression systems in withdrawal facilities and the X-343 facility-prevent large fires (initial condition assumption, EG 5 only).

' The fixed fire suppression systems in withdrawal faci'ities and the X-343 facility are identified as i
important to safety S9Cs. See Section 3.8 for details including safety classification.

4.3.2.3 Miscellaneous Waste Storage and Handling Facilities The miscellaneous waste handling and ttorage facilities are listed in Table 4.2-9.
4.3.2.3.1 Large Fire (External Event) a.
Scenario. Description The miscellaneous waste storage and handling facilities primarily handle and stcre RCRA waste as well as uranium bearing compcunds. The most significant hazard associated with a fire is the RCRA waste. Fires can be caused by welding and burning operations, electrical failures, vehicle accidents, etc.
The Fire Prctection Program (see Section 5.4) provides a high degree of protection from fires that could cccur within the miscell.meous waste storage and handling facilitica (see Table 4.2-9). The protection provided is both preventive and mitigative. Some facilities con:ain fixed fire protection systems, (e.g.,
sprinklers and fire extinguishers) which provide additional m.tigation for fires. Preventive measures (administrative practices) reduce the likelihood of any significant fires within facilities by controlling the amount of combustible materials allowed and by maintaining good housekeeping practices. Therefore, a k
large fire is :ategorized as an EBE.
This event was evaluated, and it was detennined that the consequences could result in significant j
on-site impact if no mitigation were provided. These consequences are based on a release of toxic material.
The primary concern associated with this event is the loss of primary system integrity and the release of toxic material. The applicable EGs associated with this event are EGs 1 and 2, as well u EG 6 in the EBE frequency range. Since there is no primary containmem system for this type of event, EG 3 does not apply. The essential safety actions associated with meeting these EGs for a large fire include (1) detection of the release, (2) notification of emergency response personnel, and (3) emergency response to evacuate the immediate vicinity and downwini locations so the exposure of on-site personnel is I
minimized.
i This event is considered to result in the worst consequences for the miscellaneous storage and handling facilities, and is therefore, a limiting event for these facilities, 4.3-131

De HPFWS provides fire water to the cascade buildings and X-343 facility (as well as other facilities not l covered by tnis TSR). For the X-343 facility, fire protection is provided to prevent a large fire from occurring, A largeJire could rupture a cylinder, l' ORTS has a total of 6 fire water pumps located in the X-640-1 pump house and the X-6644 pump house.
l Dere are four electric pumps (2 in X-640-1 pump house and 2 in X-6644 pump house) and 2 diesel pumps (1 in X-6401 pump housand 1 in X"$6BL pump house). The electric fire pumps are normally in a stardby condition, ready to start as the level in the high level storage tank decreases. The automatic start feature is not required for pump operability. Diesel powered pumps do not normally auto start. The minimum required diesel fuel supply for etich diesel backup pump to ensure that these pumps can perform their required safety fimetion is 50 gallons.
The pumps in the X-6644 pump house take suction from a pair of above ground tanks and the pumps in X-640-1 pump house take their suction from :he makeup water system. Alternative flow can be l
accomplished by utilizing available fire trucks. hoses, hydrants, or any other means determined to be l
appropriate by the Authority Having JusAtiction (AIU). This arrangement provides adequate diversity to j
ensure ready availability of makeup water to the elevated tank. [SAR section 3.8.7.2]

SURVEILLANCE REQUIREMENTS:
SURVEILLANCE FREQUENCY SR 2.4.3.2.a-1 Verify that the HPFWS X-640-2 storage tank level is a Monthly 90% full and is valved to the distribution system.
j SR 2.4.3.2.a-2 Visually inspect the exterior of the HPFWS X-640-2 fire Amiually water storage tank.
BASIS:
The HPFWS X-640-2 storage tank is designed to supply sufficient pressure to provide flow trough the building sprinklers. This pressure is assured by the height of the tank (265 feet at the tant. bottom).
The tank holds 270,000 gallons of water (at 90% full) and is capable of providing the Ncessary flow rate to the sprinklers for approximately 100 minutes. The accident analysis for a large fire in the 1
cascade facilities requires a flow 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 sequentially as the elevated l
tank level declines.
When the tank is isolated, the system pressure would normally be maintained by the HPFWS jockey l
pump. If HPFWS jockey pump is not available, pressure would be maintained by one of the other HPFWS pumps.
l l For the withdrawal facilities and the X-343 facility, fire protection is provided to prevent a large fire from occurring. A large fire could rupture a cylinder. [SAR Section 3.8.7.2]
