Identification of PV1-P and PV2-P as Machine Cooling Water "main" and"spare" purge vacuum pumps was removed throughout the procedure.Use of the Machine Cooling Water supply regulator was removed.Sections involving pump pressurization were removed. The two pumpstartup sections were consolidated down to one section. Procedure wasupdated with new Instrument Air valve and regulator identifications, andthe Instrument Air seal purge operating range was changed.

Reason for the Change:Purge Vacuum pumps are identified as PV1-P and PV2-P on drawing X-3001-0102.40-ME and labeled as such in the process building.Removing "main" and "spare" from the procedure eliminates confusionwhen operating the Purge Vacuum system.

Use of the Machine Cooling Water supply regulator 13-MWS-CV1 RV isno longer required as the new vacuum pumps will regulate the pressureand flow of cooling water through an internal thermostatic valve.

Procedure operating sections involving pump pressurization wasunnecessary since the pumps are backfilled from the discharge line assoon as the pump stops. Additionally, both pump startup proceduresections were essentially the same so they were consolidated down toone section for use with both pumps.

Instrument Air valve numbers were changed to agree with drawings.

Additionally, procedure steps werechanged to only check the status of the controller.

Revised the Integrated Safety Analysis Summary to remove flow

diagrams about centrifuge assembly, disassembly, and select repairactivities; indicate use of procedures for centrifuge assembly,disassembly, select repair, and monitoring and examination activities;provide some discussion about the use of the X-7725 buffer storage areafor centrifuge assembly, disassembly, select repair, and monitoring andexamination activities in addition to the X-3001 Process Building and X-7726 Centrifuge Test and Training Facility; and clarify that use of the X-3001 Process Building for centrifuge assembly, disassembly, selectrepair, and monitoring and examination activities means the X-3001 Train3 or X-3001 transfer aisleway.

Reason for the Change:The Lead Cascade Facility Integrated Safety Analysis Summary wasoriginally written with the assumption they would be textbooks for the U.S.Nuclear Regulatory Commission to use in developing their knowledgebase for oversight of the American Centrifuge Program.

Detail about centrifugeassembly, disassembly, and select repair activities was provided to assistthe U.S. Nuclear Regulatory Commission in understanding the AmericanCentrifuge Program in its entirety. Centrifuge assembly, disassembly, andselect repair activities do not present any credible accident sequencesthat could exceed the performance requirements per 10 Code of FederalRegulations 70.61. Other changes were made to clarify where activitiesare preformed and that activities are performed in accordance withprocedures.

Description of Change: Rev 0 70.72(c) are met.

Add the outputs of the clamp limit switches to the hoist run permissiveoperation sequence.

Reason for the Change:Recently, an operator failed to note that the clamps were notOPEN/DISENGAGED and the status light was burned out, so an attemptto lower a machine with the clamps still closed resulted in cocking themachine to one side. By adding the output of the clamp limit switches tothe hoist run permissive operation sequence, the hoist will not receive theRUN signal until all limits are made (clamps fully OPEN/DISENGAGED).This will eliminate some potential human interface errors.

Description of Change:Use the X-7725 Transporter Battery Maintenance Room for curing thepaint on the centrifuge casing interiors. This is a temporary assemblyactivity that could involve up to 50 casings. The curing effort requires theuse of supplemental heat to provide forced air through the casings at aminimum of 120 degrees Fahrenheit. The temperature in the casing isnot expected to exceed 200 degrees Fahrenheit. Insulating blanketsdraped over the casings are used to help maintain temperatures insidethe casing. The blankets are made of noncombustible material. Portable30 kW electric heaters will be used to create the necessary temperatureconditions. The proposed activities meet National Fire ProtectionAssociation requirements. The room tempearture will be monitored toensure ceiling temperature does not approach levels that might impactthe sprinkler heads. The room temperature is not expected to exceed160 degrees Fahrenheit.

Reason for the Change:The initial start up of Lead Cascade 3 has indicated a problem associatedwith the casing interior paint. The coating was not allowed to fully cureprior to Lead Cascade 3 operation resulting in unexpected centrifugeoperating conditions. To support Lead Cascade 3 installation andoperation, some of the casings that have been previously installed andconditioned need to be cured to ensure the interior painted surface iscured. The coating is dry to touch when received; however, the curingprocess must be complete.

The twodisconnects should be wired in series so that either of them disconnectthe rail from its power supply. The purpose of this change is to put thedisconnects in series.

Reason for the Change:The current configuration introduces a safety concern if personnelworking on the crane think they have isolated the crane from its powersupply by locking out the disconnect on the maintenance platform, whenin reality, a portion of the rail is still energized.
