, March 1, 1993 GE understands that a follow-up amendment is required to completely resolve all design related issues.

It is expected that such an amendment will be provided by early December to facilitate FSER documentation of issue closure.

The follcwing is a detailed listing of unresolved items in the two chapters with text entries following those items which were discussed with GE with brief discussions of agreements made and revised staff findings.

1.

Summary of Open Items Discussed 3.4.1-1 Flooding in Turbine building The staff indicated that the SSAR needs a discussion of protection from flooding due to breaks in turbine SW and condenser circulation water. The SSAR also needs a summary of those design features that provide protection.

GE needs to describe how a break in the turbine building could effect safety related equipment in the reactor building. GE will discuss the risk evalua-tion it has done along with mitigation features.

Insert C was provided in as a proposed insert to the SSAR.

Based on this information, this item is resolved and becomes a confirmatory item (not numbered).

t 3.5.1.2-1 Missiles from rotating equipment GE proposed adding a reference to the SSAR for a methodology to determine the thickness of housings for rotating equipment which was provided to the staff.

It is the proprietary PED-18-0389, " Missile Generation Study" for Peach L

Bottom. The staff will place it on the docket and GE committed to providing a non proprietary version. This item remains open while the staff reviews the methodology.

l 3.5.1.2-2 ITAAC-protection of S/R equipment from missiles This ITAAC needs to indicate the requirement to perform an inspection, l

analysis to demonstrate the required protection. GE may choose to include a building or a Generic ITAAC.

r 3.6.1-1 ITAAC-protection safety equipment from DBA The staff wants building ITAAC to include protective features to avoid damage to SR equipment from a pipe break. GE is considering putting these features in the building ITAAC.

i i

. March 1, 1993 3.11.3-1 ITAAC-EQ radiation concern This item remains unresolved.

3.11.3-2 EQ radiation concern The staff wants a commitment from GE that the total integrated dose for electronic equipment will not exceed 1000 R.

This will define the mild environment.

It was not clear what GE's position was on this issue and what the definition of the harsh environment will be. GE indicated that it would add the following in the SSAR:

"all equipment subject to exposure in excess of 1000 R will be qualified in accordance with 10 CFR 50.49."

This item was resolved and will become a confirmatory item (to be numbered).

3.11.3-3 Integrated gamma dose in primary containment GE committed to recalculate the integrated gamma dose level for containment and will include it in the SSAR.

If it is lower than that experienced ir operating plants a justification will be provided.

9.1.3-1 Use of the RHR as part of the FPC The staff needs GE to verify that functions of the RHR will not be affected during Mode 5 when RHR is being used for fuel pool cooling during the first 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> after shutdown. Also GE needs to verify that the TS will not be violated in this mode.

9.1.5-1 ITAAC-RxB crane capability under SSE This issue is resolved in SSAR Amendment 21. This issue is closed. This should not have been labeled as ITAAC.

9.1.5-2 CB and secondary containment cranes under SSE This issue is resolved in SSAR Section 9.1.5.2.2.4 Amendment 17. GE will clarify the wording.

This action is Confirmatory (not numbered).

9.1.5-3 Discrepancies between SSAR Table 3.2.1 and Section 9.1 4

The jib crane will be deleted from the design. GE needs to update the SSAR to l

delete jib crane from SSAR Table 3.2-1.

GE has committed to revise the SSAR j

to make the use of the refueling platform consistent in SSAR Table 3.2-1.

The open item is closed. These actions are confirmatory.

9.1.5-4 Non-single-failure-proof lifting devices in CB j

GE has revised the SSAR Section 9.1.6.6 Amendment 21 to specify the require-I ment for protection of safety related loads from non single failure proof loads. GE needs to revise Figs.1.2-20 and 1.2-21 to include additional equipment hatches. The open item is closed. The second part of this issue is confirmatory.

l 9.1.5-5 ID all hoists in RB, DW, steam tunnel, refuel platform f

The open item is resolved. This is now a Confirmatory item for GE to revise Section 9.1.6.6 to identify that the COL applicant will provide information on all load handling systems. See Enclosure 3 markups of SSAR.

j 9.1.5-6 Interlocks, limit switches for loads over spent fuel This open item is resolved and is now confirmatory for GE to include in SSAR Section 9.1.6 to clarify that the COL applicant will provide details on the limit and safety devices for automatic and manual operation of all heavy load handling systems. The staff needs to properly address how this item will be

~

resolved by the addition of a list of systems which are out of scope in SSAR Chapter 1.

9.1.5-7 Load-lifting systems outside design certification This item will be resolved in conjunction with the resolution of Open Item 1.2.6-1.

i 9.2.4-1 Sanitary and potable water system conceptual design The information was included in Amendment 21. The staff still needs to evaluate the acceptability of the description. The system is designated as an I

interfacing system and therefore licensee design requirements will be treated l

as interface requirements.

l 9.2.11-1 RCW system heat exchanger design capacity l

GE provide a draft write-up to clarify the heat exchanger capacities to be l

included in a future SSAR amendment. This item needs further discussion.

i 9.2.13-1 ITAAC-HVAC emergency cooling water system

~

This item in the DFSER text concerns the need for analyses regarding the HECW system ability to recover post SBO.

It was incorrectly titled in Chapter 1.

The staff believes that GE needs to provide additional information in the SSAR beyond what is included. GE needs to show that the EQ analysis bounds the conditions following a SB0 after 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. GE agreed to do such an l

analysis.

9.2.15-1 RSW interface criteria in SSAR GE committed to including a requirement that the RSW piping be no more than 2 km in length.

l This is still under review.

9.2.16-1 Discrepancy in SSAR concerning number of TSW pumps Amendment 21 corrected this information and this is resolved.

9.3.1-1 Nitrogen supply requirements (ANSI MCll.1-1976)

The staff indicated that GE should add a statement in the SSAR of a particu-late requirement of 5 microns for instrument air and high pressure nitrogen and a statement that components using these systems must meet this require-ment. GE indicated that these changes would be made in Sections 9.3.1 and 6.7.2.

This item becomes a confirmatory item (not numbered).

t 9.3.1-2 Instrument air compliance with GDC 1 The staff indicated that GE should add a statement in the SSAR of a particu-late requirement of 5 microns for instrument air and high pressure nitrogen-and a statement that components using these systems must meet this require-ment. GE indicated that these changes would be made in Sections 9.3.1 and 6.7.2.

This item becomes a confirmatory item (not numbered).

staff committed to providing GE a list of recommended ITAAC and Tier 1 information requirements based on the discussions of unresolved design related items identified during the two-day meeting. The following list was provided as a first cut at the total list which will be provided to GE by November 6, j

i 1993.

1.

Test for water level switches in control building.

j 2.

For condenser pit verify flood protection isolation function.

f 3.

Verify that there are no penetrations from steam tunnel to control t

building.

4.

Pressurized gas bottles will not generate missiles as themselves or by parts thereof by verifying protection features.

l i

5.

Protection of SR equipment from failures of NSR SSCs not housed in tornado-resistant buildings (0 pen Item 3.5.2-1).

6.

Modify EQ ITAAC to include harsh environment requirements of 50.49(f)

(0 pen Item 3.11.3-1).

i 7.

New fuel storage concerns (0 pen Item 9.1.1-1).

8.

Fuel pool cooling (0 pen Item 9.1.3-2).

Protection features for piping used for cooling by RHR.

l 9.

Overhead heavy load handling system. Need for a load test.

i GE indicated that it would consider the list in its preparation of a Tier 1 document reflecting Chapters 3 and 9 which would be completed in November and provided to the staff to support a follow-up meeting with the staff. This I

meeting will be held in December to resolve the Tier 1 and ITAAC issues for the two chapters.

l FUEL POOL COOLING DESIGN CHANGE A discussion was held on the fuel pool cooling function. GE indicated that in j

the post LOCA scenario, with the assumption of no cooling will result in j

boiling which may not be addressed by the SGTS capability design. GE has i

analyzed two offload scenarios (maximum normal and abnormal heat loads) but there is still a concern over the saturation of the SGTS by the steam from boiling.

insert a Pipe penetrations below design basis flood level will be sealed against the resulting hydrostatic head from a moderate energy pipe failure inside the tunnel, or in a connecting building.

l insert b Four Channels (3 out of 4 logic) sensors are provided at two different levels in each division of control building basement to warn operators from service water pipe failures inside the control building. The first level alarm is 150mm above the basemat to provide to warn operators of flooding in a division. The second level alarm at 800mm is used as a backup for operator action.

Its height was selected to allow the operators 30 minutes to take action.

Failure of the operators to take action, the second level alarm would signal the failed service water division to stop the pumps and close isolation valves. Only the service water system has enough inventory to reach the second level alarm.

insert c 3.4.1.1.2.5 Evaluation of Turbine Building Flooding Events I

Circulating Water system and Turbine building service water system are the i

only systems large enough to fill the condenser pit; therefore, only these two systems can flood into adjacent buildings, i

A failure in either of these systems will result in the total flooding of the turbine building upto grade. Water is prevented from crossing to other building by two means. The first is a normally closed alarmed door in the connecting passages between the turbine building and service building.

The second is that the radwaste tunnel will be sealed at both ends to prevent water from either entering the tunnel or leaving the tunnel. A large hydrostatic head is prevented by a large nonwatertight truck door at grade to provide a release point for any water.

Because of the large size of the circulating water system. A leak will fill the condenser pit quickly. Monitors were added in the condenser pit of the turbine building to provide leak detection and an automatic means to shutdown i

the circ water system in the event flooding event in the turbine building (See Chapter 10.4.5.5).
