USEC A Global Energy Company October 19,1998 GDP 98-0219 Dr. Carl J. Paperiello Director, Oflice of Nuclear Material Safety and Safeguards Attention: Document Control Desk U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Paducah Gaseous Diffusion Plant (PGDP)

Docket No. 70-7001 Certificate Amendment Request - Update the Applicatian Safety Analysis Report - Proposed Changes

Dear Dr. Paperiello:

By letter dated October 31,1997 (Reference 1), USEC submitted a certificate amendment request (CAR) containing the Safety Analysis Report Update (S ARUP) required by Issue 2 of DOE /ORO-2026," Plan for Achieving Compliance with NRC Regulations at the Paducah Gaseous Diffusion Plant" (the Compliance Plan), for NRC review and approval. By letter dated March 31, 1998 l

(Reference 2), USEC submitted proposed changes to the SARUP certificate amendment request.

This letter provides additional changes to the SARUP certificate amendment request.

USEC's October 31,1997 letter (Enclosure 1, Table 1, item 3) contained the following commitment that required SARUP changes and a response to the NRC:

Codes and Standards for Process Building Cranes Appendix A of SAR Chapter I will be updated to reflect the extent to which the design and inspection of cell floor process building cranes (and associated lifting fixtures) satisfy applicable industry codes and standards. Necessary changes to SAR Chapter 1, Appendix A, will be submitted to the NRC by October 19,1998.

As shown in the attached changes, SARUP Chapter 1, Appendix A, has been revised to apply the same sections ofstandard ANSI B30.2 that are currently applied to the liquid UF cylinder handling 6

cranes to the four process building cranes that are normally parked over cascade equipment (see the discussion in SARUP Section 3.15.9.2).

Proposed Changes Certificate Amendment Request Update the Application Safety Analysis Report Detailed Description of Change 1.0 Purpose The purpose of this submittal is to provide revised pages to the Safety Analysis Report Update (SARUP) previously transmitted in USEC letters GDP 97-0188, dated October 31,1997 (Reference 1), and GDP 98-0064, dated March 31,1998 (Reference 2), for NRC review and approval.

l 2.0 Description of Submittal The following changes are included in this submittal which modify the latest version of the SAR Update certificate amendment request. The revised pages are included in Enclosure 3.

A.

The Revision Log has been updated to reflect the changes included in this revision.

B.

The List of EfTective Pages has been updated to reflect the changes included in this revision.

C.

SARUP Chapter 1, Appendix A, Section 1.11 has been revised to include the four process building cranes (one each in buildings C-310, C-315, C-333 amd C-337) that are normally parked over cascade equipment in the commitment to sections of ANSI B30.2, Overhead and Gantry Crane Design and Inspection,1990 Edition (including Addendum A,1991). As discussed in the October 31,1997 SARUP submittal, these four process building cranes are classified in the SARUP as AQ SSCs. Consistent with this change in quality classification was a commitment to identify industry codes and standards that would apply to these cranes. This revision fulfills that commitment.

D.

SARUP Chapter 1, Appendix A, Section 1.14 has been revised to correct the year of record for ANSI B30.20 from 1992 to 1993.

i E.

SARUP Sections 3.15.6.2.2 and 3.15.6.2.3 have been revised to clarify the reference to codes and standards for liquid UF cylinder handling cranes. The sections referenced in Chapter 1, 6

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 contained in SARUP Chapter 1, Appendix A.

F.

SARUP Section 3.15.9.2.2 has been revised to clarify that the industry codes and standards applicable to the process building cranes only involve inspection and testing requirements and 4

GDP 98-0219 i

Page 2 of 2 not design requirements. SARUP Section 3.15.9.2.3 has been revised to reference SARUP Chapter 1, Appendix A.

G.

The Basis statements for SARUP Technical Safety Requirement (TSR) Sections 2.2.4.1, 2.3.4.2, 2.5.4.2, and 2.6.4.2 have been revised to remove one of two references to SARUP Chapter 1, Appendix A, for liquid UF cylinder 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. The discussion preceding the deleted reference involved design guidance. There are no changes to the commitments to sections ofcrane codes and standards in S ARUP Chapter 1, Appendix A.

j' The liquid UF. cylinder handling crancs shall not fail in a manner to cause US primary system failure. The liquid UF. cylinder handling crancs provide for the safe movement of liquid US cylinders.

. This function is accomplished by ensuring liquij UF handling crane lifting components and load braking j

systems are maintained to prevent an uncornrolled dropping of a cylinder. Both engineering and

adrainistrative controls are used to limit the areas (i.e., none controls) that liquid UF. handling cranes can be operated. These zone controls are usel to minEmize the risk associated with dropping a liquid cylinder, o': similar weight load, on operating process equipment.

3.1'5.6.2.3' System Evaluation The required safety function is to not fail in a manner that causes UF primary system failure 6

(i.e., dropped cylinder) during normal operation, an evacuation of facility event, or natural phenomena l events. The 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 j the crane can operate correctly. (Refer to Chapter 1, Appendix A for commitments to ANSI standard l inspection and testing requirements). In addition, the cranes are designed so that when the controls are released (e.g., evacuation of facility event), only small compensatory movements occur due to momentum after the crane drive mechanism stops and brakes are applied but these movements have no safety significance. The cranes were evaluated to 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 eanhquake and wind. Floods do not reach the elevation of the facility to threaten crane integrity.

Failure of the crane lifting components or load braking system while lifting a liquid-filled UF6 cylinder could result in dropping the cylinder and rupturing the cylinder. Therefore, a load test is performed periodically.

Engineering (i.e, limit switches, etc.) and administrative controls are also used with liquid UF6 cylinder handling cranes to minimize the risk of the cranes dropping a liquid cylinder, or similar weight (A

load, on operating process equipment. The engineering controls for liquid handling cranes used in the i

various process buildings are discussed in Section 3.7.3.1.2. The administrative zone controls (such as V

for the feed facilities) are incorporated in the applicable procedures.

Based on the analysis, the cranes can accomplish the required safety function.

3.15.6.2.4 System Classification The liquid UF cylinder handling cranes are required to perform the following safety function:

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

The cylinder failure event is classified 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-filled cylinder.

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

6 3.15.6.2.5 Boundary The Q boundaries for the liquid UF cylinder handling cranes, including associated lifti,g 6

fixtures, are defined in Table 3.15-1.

3.15.9.2.1 Safety Function i

The cell floor process building cranes shall not fai! in a manner that will cause a large UF release 6

during:

Normal operation, Natural phenomena events with the cranes in the parked position and An evacuation event due to a release of the controls.

3.15.9.2.2 Functional Reauirements The system shall meet the following functional requirements to ensure the capability to accomplish the required safety functions:

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.

6 The 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.

3.15.9.2.3 System Evaluation

.Ih 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.

6 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. Additional 6

assurance is provided by ongoing inspections and tests (Refer to Chapter 1, Appendix A for commitments to ANSI standard inspection and testing requirements).

l l

The process building cranes are parked in a standby location when not in use. There are two cranes (one each in the C-333 and C-337 facilities) that are normally parked over unit bypass piping.

Analysis indicates these process building cranes will not fall from their parked positions during an evaluatien basis earthquake, and they are not affected by the evaluation basis flood or high wind events.

i The use of these building cranes for moving a heavy load is infrequent because it is only needed when a piece of major equipment has failed. 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.

In the C-310 product withdrawal facility, one process building crane is parked over the Normetex l

pump located on the North end of the building. An evaluation of this crane determined that it would not fail from its parked position during an evaluation basis earthquake. In the C-315 tails withdrawal facility, i

one process building crane is parked near (but not directly over) the Normetex pump on the south-east i

side of the building. Akhough the C-315 process building crane was not seismically evaluated, this crane is equipped with drop plates that will minimize the risk of it falling during an evaluation basis earthquake.

i BASIS:

Cranes that transport cylinders containing liquid UF, or solid cylinders over liquid UF. CYLINDERS are designed with a minimum lifting capacity of 18 tons. The associated lifting fixture is designed with a

(~~'h safety factor of 5:1. The 5:1 safety factor indicates that the load-bearing members of the lifting device

)

shall be capable of lifting five times the combined weight of the fixture's rated load and the weight of the fixture without exceeding the ultimate tensile strength of the construction materials. The use of 5:1 safety factor has been shown to provide a lifting fixture which meets the design factor guidance presented

{

l in applicable industry standards.

The cranes are required to prevent dropping a liquid-filled UF. CYLINDER or a solid cylinder onto a liquid UF CYLINDER that could result in a cylinder failure event and a large release of QF. This event is classified as an Evaluation Basis Event whose consequences could exceed off-site Evaluation Guidelines. The function performed by the crane is passive. In addition to the surveillances specified above, cranes handling liquid UF are 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. [SAR Section 3.15.6.2]
