UNITEDSTATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D. C. 20555 JUL 30 1984 APPLICANT:
Niagara Mohawk Power Corporation (NMPC)
FACILITY:
Nine Mile Point Nuclear Station, Unit 2
SUBJECT:
SUMMARY
OF MEETING WITH NIAGARA MOHAWK POWER CORPORATION (NMPC)
ON OPEN ITEMS FROM THE DRAFT SER On March 20, 21 and 22, 1984, the NRC staff met with representatives from Niagara Mohawk Power Corporation in Bethesda, Maryland to discuss open items from the draft SER.
Enclosure 1 contains a list of the open items that were discussed.
Hyydrot o H Open Item (5), protection of the main stack from wave forces from PMWS, was discussed.
This protection need only be considered if the main stack has a safety-related function such as being considered in analysis of releases and conformance to 10 CFR 100 guidelines.
Failure of the main stack does not appear to jeopardize other safety-related structures or equipment.
Open Item (6), adequacy of ultimate heat sink.
the limiting ultimate heat sink (UHS) of 77'F may be too low for uninterrupted operation.
This number would be used in determining a technical specification (T.S.) condition.
NMPC should reevaluate this temperature as a design basis temperature.
In addition NMPC should identify if this is a surface or depth temperature.
Auxiliar S stems Open Item (82) protection against hydrogen accumulation in the battery rooms.
Information on the fans in the battery rooms is contained in FSAR Appendix 9A.
Lights on the control room panel indicate the start of the second fan.
Open Item (81) design capability of CB HVAC.
(a)
Response
to F410.42 on chlorine detection.
Draft SER section 2.2.2 evaluates the hazards from chlorine and determines there is no significant chlorine hazard at the NMP-2 site.
Therefore the review of the chlorine detectors is not necessary.
(b)
Response
to F410.43 on the Spent Fuel Pool Area Ventilation System.
The NRC staff will review information submitted in the FSAR sections 9.4 and 6.5.1.
Open Item (84)b, tornado missle protection for diesel generator louvers (F410.1).
Figure 1.2-16 in the FSAR shows the design of the concrete barrier to protect ventilation openings in buildings housing safety related equipment.
The NRC staff will review this design, 8408080ih4 840730 PDR
- DOCK 050004l0 E
Open Item (86), diesel generator building HVAC system conformance to GDC 4 is the same as Item (85) above.
Open Item (61), pipe break in the BWR scram system (F410.16).
Response
to generic letter, May 5, 1981 NMPC is to provide additional information on levels, separations and water tightness in the FSAR.
The design as described during the meeting may be sufficient.
Open Item (20),
(a) tornado missle protection for diesel generator exhaust outside 5 air intakes for HVAC systems same as (84) above.
(b) safety related buried piping.
NMPC to provide locations of and description of provisions taken to protect safety-related buried piping/ductwork.
The location of non safety-related buried piping are to be included.
NMPC was not aware of any safety-related buried piping, but the safety-related buried HPCS ductbank was discussed.
Open Item (21), effects of postulated pipe breaks.
Additional information in response to F410. 15 is to be provided by NMPC.
Open Item (73), light load handling system.
Additional information is to be provided by NMPC.
Open Item (74), heavy loads.
Additional information is to be provided by NMPC.
Open Item (80), protection of safety-related equipment against flooding.
NRC staff to further review information submitted in the FSAR with respect to this issue.
Chemical En ineerin Open Item (79), post accident sampling
( II.B.3).
NMPC will incorporate core damage information into the FSAR.
Unit 2 should have the same EPP for post accident sampling as Unit 1.
NMPC may be able to submit this EPP in advance of other EPP's as this should be the same as Unit l.
Fire Protection Open Item (88), potential systems interaction.
NMPC should review each area of concern to determine whether mechanisms by which fire and fire fighting systems may cause the simultaneous failure of redundant or diverse trains have been adequately considered in the design.
NMPC should document the results of the review of each area in the FSAR.
Open Item (89), administrative controls (fire protection).
NMPC should verify in the FSAR that the administrative controls for fire protection meet BTP CMEB 9.5-1.
Open Item (90), fire brigade and fire brigade training.
NMPC should verify in FSAR section 9.5.1 that the fire brigade, including equipment and training, meets the guidelines contained in BTP CMEB 9.5-1, Section C.3
t'/
Open Item (91), qualification of fire doors.
All fire door assemblies at Nine Mile Point 2 should be tested and labeled in accordance with the National Fire Protection Association (NFPA) 252, "Fire Tests of Door Assemblies" Open Item (92), floor drains.
NMPC should revise the FSAR to verify that floor drains are adequately sized to remove expected fire fighting water without flooding safety-related equipment.
Open Item (95), emergency lighting.
NMPC will revi'se the FSAR to include a statement that required lighting will be provided.
Levels of illumination should also be provided.
Open Item (97), qualification of electric fire pump.
NMPC should provide a comparison between UL listed and installed fire pump controller.
NMPC should also show this is a fire pump, not a nuclear pump.
Open Item (98), valve supervision, NMPC should commit to NFP-26.
Materials En ineerin Open Items (63) P-T (pressure-temperature curves),
P-T curves are to be provided as discussed in Section 5.3.2 and 5.3.3 of the draft SER.
Open Items (62), lead factors in surveillance
- capsules, and (64), ratio of neutron flux density of specimens in the surveillance capsule to peak neutron flux density at RPV, are the same items.
Effluent Treatment Open Item (68) exceptions and deviations to R.G. 1.52, rev. 2.
Flow recorders should be provided in the control room.
NMPC should either provide these or provide justification for not having them.
NMPC will check if flow recorders are to be installed.
The flow recorders would also facilitate periodic testing of filters.
Procedures and S stem Review (Procedures)
The responses to the requests for additional information (RAI's) were discussed as follows, RAI
%0.06 640.07 640.08 Abstract 43 should be revised to specifically indicate the loss-.
of-air-supply tests conducted to RG 1.68.3 NRC staff and consultants are reviewing response submitted in Amendment 8.
Response
may be acceptable.
Part 2 - the exception of RG1.108 should be deleted and NMPC should commit to a 69 start test parts 354 -
NRC staff and consultants to review response in Amendment 8.
<<j
640.09 Revision to FSAR or response to 640.09 is necessary as discussed in draft SER.
640. 10 5 640. 11 NRC staff and consultants are reviewing response submitted in Amendment 8.

640. 13
Response
to be submitted in Amendment 9.
640.14 NRC staff and consultants are reviewing the response submitted in Amendment 8.
The response appears sufficient.
640.15 Duplicate test abstract was deleted.
640. 16 NRC staff and consultants requested the modes be clearly numbered.
640.18 Draft SER 2.2.2 evaluated the hazards form transportation routes and nearly facilities at the NHP-2 site.
The results of that review did not identify toxic substances which would be a hazard to NMP-2.
Therefore testing of the control building HVAC system for protection against toxic substances may not be necessary.
640. 19 NRC staff and consultants are reviewing the response submitted in Amendment 8.
The response appears sufficient.

Geotechnical Open Item (16), update of slope inclinometer and rock extensometer
- data, the slope inclinometer and rock extensometer data should be updated and through September, 1984.
The NRC staff will review the data submitted through Amendment 6 for the level of detail provided.
Open Item (17), dynamic stability of the slopes of the revetment ditch, additional information on this issue may be forthcoming in Amendment 9.
The information to be provided should include a description of the analysis and the results.
Procedures and S stems Review (Systems)
Open Item (133), evaluation and development of procedures for transients
( I.C. 1), this issue is to remain open at present.
Procedures should be available prior to the SER.
Other Issues 1ll<<p l<<0 <<SE, digs concerning the reactor systems area were discussed.
These areas would
remain as open items in the draft SER as the information has not yet been submitted on the Nine Mile Point 2 docket.
gualification testing for the diesel generators was also discussed.
Additional information to be submitted concerning the similarity of the diesel generators to qualified diesel generators and testing to be performed was discussed.
