On June 9, 1988, representatives of Niagara Mohawk met with members of the Nuclear Regulatory Commission staff to discuss their comments and seek clarifications regarding the Safety Evaluation Report (SER) related to 10 CFR 50 Appendix J dated May 6, 1988. As a result of that meeting, Niagara Mohawk was requested to submit a letter describing the clarifications and agreements reached at the meeting regarding the implementation of the SER. Enclosure 1 to this letter is responsive to this request.

Also included in this letter are three other enclosures. These enclosures contain information requested by the Nuclear Regulatory Commission at the meeting or during subsequent discussions. Enclosure 2 contains justification of the Niagara Mohawk position related to the Shutdown Cooling System.

Enclosure 3 includes information and a discussion pertaining to containment penetrations which Niagara Mohawk has determined do not require Type 8 testing. Enclosure 4 provides the additional information that will be included in the current Containment Spray System Operating Procedure

(¹Nl-OP-14) to assure that a water seal is established and maintained during a LOCA at the isolation valves.

A schedular exemption to 10 CFR 50 Appendix J for the Emergency Cooling System condensate return valves was requested in a separate letter dated June 23, 1988 (NMPlL 0274). In addition, as discussed at the June 9 meeting, revised 1988.'oi Technical Specifications consistent with the Nuclear Regulatory Commission's Safety Evaluation Report dated May 6, 1988, and the clarifications contained in this letter would be submitted between 60 to 90 days after the meeting.

They will be submitted during August I-(

ENCLOSURE 1

COMMENTS, CLARIFICATIONS AND AGREEMENTS RELATIVE TO THE

., NRC-SER ON THE PROPOSED TECHNICAL'PECIFICATIONS.AND EXEMPTION'EQUESTS RELATED TO 10 CFR 50 APPENDIX J RE UIREMENTS The following SER sections and technical issues were discussed and resolved in the NRC/NMPC meeting held on June 9, 1988, in Washington, D.C. The comments, clarifications, observations and agreements related to each area are included below.

Reactor Cleanu S stem-Relief Valve Dischar e (IV 63.1-01 and -02)

NMPC has no comments on this section of the SER and will comply with the interpretations of the SER. Niagara Mohawk concurs with the NRC staff that the relief valve discharge line will not lead to an atmospheric release path outside containment. Thus, it is not required to be subject to Type C testing. This is primarily due to the fact that the discharge check valves are included in the water-.sealed extension of the containment

'(in. the'.Torus),.and..that the'system is...composed .of..safety-related

."components.

Core S ra S stem-Pum Dischar e (IV 40-05 and -06)

These valves are on the core spray test line to the Torus and are not currently identified in the NMPl Technical Specifications as being tested per Appendix J requirements . However, they are tested with the core spray high pressure/low pressure interface check valves in accordance with Technical Specification 3.2.7.1. Since the keep-fill system is on the upstream side of these valves, they are being tested in the reverse direction from their normal isolation function (from the vessel side instead of from the containment side). The NRC indicated that this was acceptable and that they understood the test configuration. Niagara Mohawk will specify leakage rate acceptance criteria for these valves in the future revision to Table 3.2.7.1 of the Technical Specifications.

Control Rod Drive (CRD) S stem (IV 301-112 and -113)

.'he SER allows credit for a water seal relative to the valve leakage path. However, if it was not clear a water test was still required for

,.these valves. ,In sections'f the SER where the water test was being required, it was specifically stated. For the CRD system, the SER indicates simply that a water seal is provided. No additional testing was specified. The NRC staff reviewers indicated that for those cases where a potentially unlimited water supply is available to provide a water seal, no additional testing is required. The NRC stated that no leak testing is required for these valves.

ENCLOSURE 1 (Continued)

Shutdown Coolin S stem-Suction & Dischar e (IV 38-01 -02 -12 and -13)

The SER states .that since. a forward direction Type C test for each valve cannot be performed without a modification, an air test between the valves

'ir

.is. an acceptable;alternate. NMPC.initially expressed concern with this test approach.""NMPC 'indicated"that this reverse accident flow test might not be consistent with the regulations and might not be viewed as a conservative test for the inner valves (38-01, 38-13). Since the inside isolation valves in the shutdown cooling supply and return lines (38-01 and 38-13) are double seat, solid wedge gate valves, reverse testing might not be indicative of accident situation leakage. It is not currently possible to test the inside isolation valves in the shutdown cooling supply and return lines as there are no manual block valves between the reactor vessel and the inside valves. Additionally, there is insufficient room inside the containment to install a valve on the line.

Another potential issue associated with the return line was discussed.

The outside isolation valve in this line is a check valve. Therefore, it might be difficult to pressurize between the valves in the shutdown cooling return line if this check valve is not tightly seated. A commitment at the meeting was made to supply the NRC with more detailed information about the system .design and,operation, the.valving

," arrangementsalternative, means-:of~per'forming,.the tests and a proposed

-NMPC;approach

to.meet.ing Appendix-J.-.requirements..

Enclosure 2 contains the requested design information about the shutdown cooling supply and return line isolation valves. It includes: the system/valve operating functions before, during and after a design basis loss-of-coolant accident; the water seal aspects of the system and the valves; and the testing capabilities of the current design configuration and the ramifications of the modifications that would be necessary jn order to provide any new special leakage tests. It also includes the proposed NMPC approach to meeting Appendix J requirements.

Containment S ra S stem-Suction (IV 80-01 -02 -21 and -22)

The containment spray, suction isolation valves are located on the line which takes suction from the bottom of the Torus. The valves are, therefore, provided with a substantial water seal between any radioactive source inside the containment, the pump suction point, the system loop itself, and its discharge path back into the primary containment

-. atmosphere.. Niagara Mohawk questioned why a water, test on these valves

'as",required since-they are similar to.the'control. rod drive hydraulic system, which has a similar, water, seal;.yet does not require a water

test.

NMPC also indicated that to do the'test in accordance with Appendix J requirements for a water test (this requires pressurizing the test cell to 1.10 Pa), the licensee would have to perform a major piping modification, including the installation of a blocking valve and test tap between the suction valves and the Torus.

5200G

ENCLOSURE 1 (Continued)

The NRC staff reviewers indicated that for these particular valves, the testing requirements were not based on. 10 CFR 50 Appendix J. Some type of

, leakage testing .is required under the Inservice. Testing (IST), Program.

The'RC staff concern in this regard focused on .the containment spray

.; "piping downstream from an isolation valve. If .this piping were to fail, the staff must be assured that the valve could- be closed and that minimal leakage would occur so as to not drain the Torus. Therefore, it was agreed that an IST test and not an Appendix J Type C test should be performed on these valves. Accordingly, a commitment at the meeting was made to revise the Technical Specifications to indicate that these valves will be tested in accordance with the IST Program. These tests would assure that the valve will close and, thus, reduce the risk of Torus drainage through it.

Containment S ra S stem-Other Valves (IV 80-15 -16 -17 -18 -35 -36

-37 and -38)

Regarding the other valves in the Containment Spray System, Niagara Mohawk indicated that if a Type C test were required to be performed on these valves, significant modifications would be necessary, such as installation of test taps and blocking valves. This would necessitate a request for a schedular exemption until 1990. It was also indi.cated,that revisions to

...the containment .spray:operating procedure were. be.ing developed which would

.assure.a water seal:in";these;lines at,a'll:times,fol"lowing,a design basis loss-.'of;coolant accident. :Based on di-scussions -related'to -other valves and systems, Niagara Mohawk concluded that if a water seal was provided, no testing would be required for these valves. The NRC staff reviewers indicated that this was correct and acceptable. Niagara Mohawk committed at the meeting to provide the subject procedure to the Resident Inspector.

A discussion of the proposed changes to the current procedure to.assure water seal conditions exist during a DBA-LOCA at the isolation valves is contained in Enclosure 4.

Emer enc Coolin S stem-Condensate Return Valves and the Drain 5 Vent Valves (IV 39-03 -04 -05 and -06)

It was agreed that a schedular exemption to 10 CFR 50 Appendix J for the Emergency Cooling System condensate return valves until 1990 would be submitted as soon as possible. A 30-day review and approval timetable was noted as being reasonable. This exemption is necessary in order to comply

with the SER requirements..imposed on the EC System, isolation valves 39-03,

,'-04, -05:and -06. The;commi.tment to include these valves, into the

.'ppendix J testing. category-will allow the removal of current emergency

'condenser vent and drain valves from the Appendix J Program. This is because they are no longer viewed as system/containment/primary coolant isolation valves.

Previous (Ma 31 1978) Submittal on T e B Penetrations Classifications (See Table 1 of Ma 31 1978 Submittal)

'Niagara Mohawk'indicated'in a Hay 31, 1978 'submittal,"that a number of

-:..= penetrations. were excluded'from receiving,a Type 8 test. -Niagara. Mohawk

'".indicated that although 'the NRC's SER referenced the NMPC Hay 31, 1978 submittal, the submittal is not specifically discussed in the NRC's SER.

The NRC staff members indicated that they would review this submittal and provide feedback if they had a problem with its content.

Subsequent to our June 9, 1988 meeting, the NRC has requested additional information relative to the Type B penetrations. Specifically, NMPC was requested to provide the bases for not performing a Type B test on those penetrations identified in Table 1 of Niagara Mohawk's letter from Hr. D.

P. Disc to G. Lear, dated May 31, 1978, as "not subject to Type B,testing."

This subject is discussed in Enclosure 4. The requested information is attached to that enclosure.

ENCLOSURE 2 ADDITIONAL SHUTDOWN COOLING SYSTEM VALVING INFORMATION Introduction The purpose of this enclosure is to provide additional information on the existing Shutdown Cooling System and its isolation valve configuration. The information includes:

a) A brief description of the design basis and the function of the system and the subject valves before, during and after a Design Basis Loss-of-Coolant Accident (DBA-LOCA).

b) A discussion of the inherent system/valve water seal aspects under accident conditions with special attention directed to dose reduction and allowable leakages.

c) More definitive information about the valves (pictorial cut-aways, vendor component data, equipment qualifications, etc.).

d) A discussion of the adequacy of the existing testing approach and the significant modifications needed.to conduct air only leakage. testing.

S stem Desi n Basis The Shutdown Cooling System forms a closed loop with the reactor recirculation system (primary coolant system). The system takes suction from one of the five recirculation loop suction lines and transports the reactor coolant through three parallel cooling loops. Each loop is made up of a pump, heat exchanger and associated loop instrumentation. The reactor coolant is cooled (decay heat removed) and returned to a different recirculation. loop. The Shutdown Cooling System piping from the external isolation valves (on both suction and discharge headers) to the reactor recirculation pump connections is designed for 1200 psig at 525 F. Piping between the suction and discharge, external to the isolation valves, is designed for 1200 psig at 350'F. The system, when in operation, is an extension of both the primary coolant system and the primary containment. However, this operation occurs only during low pressure, normal shutdown conditions.

The system is located within the area serviced by the Secondary Containment System (Secondary Containment-Reactor Building, Emergency Ventilation System

[referred to generically as the Standby Gas Treatment System],'.and the Main

.-Stack). Any .significant leakages. within or. between other, systems and the

. shutdown 'cooling system are monitored and"controlled by the operator in the Main Control Room. The system is subjected to piping integrity monitoring, component availability/reliability surveillances and major equipment operability tests. Equipment in the system is designed to the plant design basis seismic and environmental conditions, and quality standards. This system is a well designed and operated plant auxiliary system. The subject valves in the system have provided reliable service.

Refer to Figure 2-1 for a simplified system flow diagram. The subject isolation valves (IV 38-01, -02, -12 and -13) are identified. A more detailed PAID is included as an attachment to this enclosure.

ENCLOSURE 2 (Continued)

S stem/Valve Function Descri tion The, Shutdown Cooling System is. designed. to cool; reactor water (remove decay heat). from 350 F to 125 F, within a 24-hour- period using two of the three "parallel:loops: ,It then,maintains,".the reactor" coolant .temperature at .125'F using one of the three loops. During normal 'plant shutdown operations, the Shutdown Cooling System is manually actuated from the Main Control Room. The four system isolation valves (38-01, -02, -12 and -13) are normally closed both during normal operation and a Design Basis Loss-of-Coolant Accident (DBA-LOCA). In addition, the isolation valves automatically close and isolate the system on low-low reactor water level, on high reactor pressure (above 120 psig) and on system area high temperature. Furthermore, the two supply line isolation valves (38-01 and 38-02) are interlocked so that only one of them can be opened at a time for testing purposes while the reactor is at This is to assure that proper isolation from the primary pressures'bove 120 psig.

coolant system is always maintained during high pressure conditions. One of the two series return line valves (CV-38-12) is a check valve which provides the necessary high pressure isolation while the motor operated valve is tested. In addition to the system isolation capabilities cited above, each individual loop is, in itself, capable of being independently monitored, controlled and isolated. (Refer to BV-38-02, -03, -04 and CB-38-06, -07 and

-08.)

In,.addition to~ the above, .a=.:system;integrity:verification -i s 'performed per Technical=;.Spec'ification .'.6;14. This:specification requires the system 'to be checked for leakage in a manner which meets or exceeds the requirements and recommendations of Section 2.1.6.a of NUREG 0578. The leakage integrity of the Shutdown Cooling System will also be maintained throughout the operating cycle. Significant intra-system leakages through the system valving, which could be of concern, can be monitored by the system temperature recorders. In addition, any significant leakage from the system can be monitored by the area temperature detectors.

S stem/Valve-Inherent Hater Seal/Dose Reduction/Allowable Leaka e During a DBA-LOCA, this system is not required to perform any safety function. It may be utilized as an alternate or supplemental long-term decay heat removal cooling system under less severe accident conditions. It is used as the primary low pressure decay heat removal system under normal shutdown conditions.

, The'system is expected to .be.,isolated during.an"accident, thus maintaining the

,'integrity, of the system and;its-.loops. .This;ensures the retention of,its

..coolant;and .its availability".for .future accident recovery services. Any accident radiological releases"emanating from the system at any time would be negligible for a number of reasons. First of all, the system is a closed loop. Second, as cited above, it is not in operation during the DBA-LOCA.

Third, any radioactivity from the reactor coolant or the primary containment systems must pass through a series of valves and piping systems prior to any release. These include the recirculation loop and/or its isolation valves, the system subject isolation valves, and the individual shutdown loop blocking valves. Most of the Shutdown Cooling System piping will be filled with water. The system, itself, is further isolated from other systems also by

.water seal aspects (e.g., the Shutdown Cooling System-Heat Exchangers are 5200G

0 ENCLOSURE 2 (Continued) water sealed by the Reactor Building Closed Cooling Hater System). During a DBA-LOCA, the shutdown system is not expected to lose any of its coolant inventory. The minor system leakages,,from .components to the environs will be treated by .'the Secondary. Containment System. Leakages from or through the valves will be;contained within the, Primary or Secondary Containment

'..isolation Systems. Significant dose -reduction credits-for water scrubbing, piping and valve plateout, transportation delay/decay, and Reactor Building environmental dilution, treatment, control and elevated release would certainly minimize any radiological impact from system isolation valve leakage far above the allowable Appendix J levels. The NRC is now giving substantial credit for the above cited dose reduction factor considerations. Historically, little, if any, credit for the above was considered in earlier Appendix 3 regulatory interpretations. The recent NRC BWR-Main Steam Line Isolation Valve Leakage study, NUREG 1169, recognizes, quantifies and allows significant decontamination factors relative to steam/radiation/leakage transport processes. The Main Steam Line system is an open-loop, steam transport, unprotected, direct environs release process. The subject system is a closed loop, water medium system housed inside a seismically qualified structure. It is serviced by an engineered/safety feature radiation leakage treatment-release process. Certainly, credit should be taken for a water seal medium when evaluating the isolation valves in the Shutdown Cooling System.

'Valve:Selection/Dut Consideration

, Gate"valves are widely-. used valves throughout the nuclear industry for plant piping systems. A very high percentage of process system valves are gate-type. The gate valve is designed for on/off service that is, completely "open" or completely "closed" operation. As such, it is used to isolate piping system by blocking flow from one component to another. Because of its singular service function, the leak tightness of the seal at the disc/seat interface is an important design parameter. Most gate valves (like the subject isolation valves) have an electric motor operator downward driven disc motion. The disc has two faces, both of which engage the seats at closure. Disc guides ensure proper alignment of the disc. The two-faced disc, referred to as a wedge, can be solid or flexible. The subject valves have a solid wedge in order to enhance higher strength capabilities. A gate valve was chosen for the shutdown cooling system isolation function based on the system operating profile. That is, totally "open" at low pressure with a minimum of flow resistances and totally "closed" at high pressure, offering a maximum of flow resistance and shut-off capabilities . The choice of the solid wedge configuration was again based on closure strength rather than valve

'plit wedge designs .which offer, more leak tightness.

Limitorque operators control.'the, subject gate valves. The electric operator "is sized to provide the torque and total'thrust needed to assure a leak-tight valve shut-off function. The combination of motor size and speed, gear ratio and stem thread assure the tight shut-off within a specified time interval.

The minimum required torque/thrust to assure tight closure is specified by the valve manufacturer and used by the valve maintenance personnel. By experience and reputation, the Limitorque operator is one of the most reliable motor operators in use. Backing up this electric operator experience is the MOVATS (Motor Operated Valve Analysis and Testing System) program. The program regularly analyzes the behavior of the electrical operator system in terms of limit and torque switch actuation, excursion time and thrust. The 5200G

ENCLOSURE 2 (Continued) valve/operator operating signatures can be compared with prior tests to determine operational performance trends and to reasonably predict how the valve will perform. within specifications in the future.

In summary, the .subject valves are not only mechanically designed to be leak-tight components, but they are also electrically operated and electronically monitored to assure that their tight shut-off function is guaranteed. Crane valves have in the past and still have an excellent reputation for good service, reliability and minimum maintenance . These particular valves have required little attention at NMP1.

Certificate of Test Ade uac of Current Testin A roach/Ramifications of Chan e Modifications Niagara Mohawk maintains that the subject valves should be exempt from Appendix J requirements or an exemption from specific Appendix J Type C air testing should be granted. The maintenance of a water seal is more than sufficient to protect the health and safety of the publica The Niagara Mohawk position is based, first, on the fact that the system is a closed loop with the primary coolant and containment systems. Second, that the system is not in operation before, during, or following a DBA-LOCA. Third, the potential subject valve leakage path is through a number of,.other .,val.ves, before and after ',the"-,i,solation,valves 'and the entire."path i,s-,water '.fi'l,led and'maintained

,so;throughout the =accident. -The fourth consideration .i,s -related to.'the fact "that. the original Appendix J -leakage requirements regarding leakage did not give credit for many currently recognized BWR features. Credit for these would substantially reduce the radiological effects cited in the FSAR, Regulatory Guides, Safety Evaluation Reports, etc. The NRC has (a) recently recognized, quantified and approved the use of dose reduction factors (e.g.,

plateout, aerosols, transportation phenomena), (b) given credit for inherent plant features (e.g., secondary containment systems and mitigators, such as reactor building effects delay/decay/plateout) and standby gas treatment (including filtering/diluting/ elevated release), and (c) taken into account valve leakage pathway attenuation characteristics (like water seals, pressure assisted valve seat leakage reduction).

The recently issued NRC Appendix J SER gives several allowances and credits specifically to the Control Rod Drive System, Reactor Cleanup System and Containment Spray System. The NRC granted credit for the following features or test allowances:

~ a), water seal credit, arrangements at, the. subject isolation valves/based on the availability of'dequate make-up .sources,

b);. credit for. the 'closed'.loop. pathways concept, c) credit for quality system designs and components (inherent in ESF systems),

d) acceptable valve leakage tests in reverse directions (as allowed by regulations),

e) water leakage testing at reduced pressures, and f) potential allowance for reverse valve seat pressure assistance.

5200G

ENCLOSURE 2 (Continued)

Similarly, Niagara Mohawk believes that the Shutdown Cooling System qualifies for these considerations.

The gate valve, being a, universal flow/stop device (that is, has the ability to allow or, stop flow in either direction) appears to exhibit the same leakage characteristic also in either direction. The forces exerted upon the symmetrical wedge-type gate on flow interruption are the same from either direction. The double seat wedge design assures two barriers to flow or leakage. The symmetrical wedge is designed to provide this two barrier concept regardless of the flow direction. Valve designers/application engineers feel that a test in the reverse direction will give similar results as one from the opposite di rection, if conducted under similar conditions.

Therefore, a test in the non-accident (reverse accident) leakage flow direction will yield results similar to those in the accident test flow direction.

A series of water tests (Procedure ¹Nl-ST-C13) were conducted at NMPl within recent weeks (6/27-28/88) to investigate the leakage tightness of the subject valves. The water volume between valves (IV 38-01 and IV 38-02) was continuously pressurized (at ~ 140 psig, which is 4X accident pressure) from a seal water source and the leakage through the valve ( IV 38-01) seats was recorded. The leak rate was 0.256,.gallons/minute. A similar test was

'conducted on .valve.(IV 38-13). Its:leak-rate,was l.:321 gallons/minute. This

,leakage measurement technique indicates that;the ..subject, valves are very tight in either direction. They are, thus, able to maintain a water seal under accident conditions. These tests also confirm/assure that the existing shutdown cooling system water inventory will be able to provide and maintain a reliable water seal on the subject isolation valves for a significant time after the accident. Niagara Mohawk will continue to periodically conduct these tests to assure that the system is maintained within its design basis envelope.

If, however, Niagara Mohawk were required to perform individual valve air or water leakage tests and meet the stringent leakage allocations while testing under simulated accident conditions (that is, in the direction of accident flows), significant modifications to the Shutdown Cooling System would be necessary. The installation of new isolation valves and/or the introduction of new system block valves and test taps would be required. The introduction of additional valving in an already operationally sensitive, single loop Shutdown Cooling System is viewed as being counterproductive. The addition of new block valves and taps do not appear to enhance either plant safety or system availability. They would contribute little to the .further reduction of

..an already insignificant, plant coolant, leakage/loss. The existing valves and

". their configurations have been proved to be a very reliable and effective arrangement. A major system disruption (modifications to install new valves, etc., or even valve leakage testing) may result in added operational considerations (such as higher man-rem exposures, new equipment support and installation problems, new and additional training, new procedures and tests, etc.). These do not appear to be safety-cost beneficial.

~Summar

.- In -summary, it is, Niagara Mohawkosition that the current valvi ng

,configuration is'dequate and'.desirable., Niagara Mohawk proposes that the

,,subject Shutdown Cooling;System valves be -considered in accordance. with the approach found'acceptable on the CRO and the reactor cleanup systems. Niagara Mohawk is proceeding to pursue this basic approach. Test and Technical Specifications are being developed to conform to those Appendix J requirements cited earlier in Enclosure Pl for the CRD and reactor cleanup systems. The NRC review and concurrence with this approach is solicited.

ENCLOSURE 3 CONTAINMENT PENETRATIONS-NOT INCLUDED IN TYPE "B" TESTS DESIGN/CONSTRUCTION DETAILS Introduction During the course of the June 9, 1988 meeting, Niagara Mohawk requested additional NRC clarification as to the acceptability of a NMPC submittal made in August of 1978 relative to the classification of NMP-1 containment penetrations. The classification listing is also attached here. The review of the subject submittal was again requested. Subsequent to this meeting, the NRC has requested additional information relative to the penetrations not subject to Type "B" testing. The information requested was:

a) Basis for exclusion from Type "B" testing, b) Typical Detailed Design/Construction Drawing of the subject non-test penetration, and c) Information as to whether the excluded testable penetrations were "vented" during Type "A" test.

Basis-for'NMP-1 T e d"B" Classification One of the conditions of operating licenses, as specified in 10 CFR 50.54(o),

is that primary containments shall meet the containment leakage test requirements set forth in 10 CFR 50 Appendix J. These test requirements include periodic verification by tests of the leak-tightness of the total containment itself and individual tests of the selective systems and components which penetrate the containment. These periodic verifications are defined on Type "A", "B" or "C" tests.

Each of the Type-tests are further specifically defined. In the regulation it states:

t t t \ t ddt dt t1 11 t dt measure leakage across each pressure-containing or leakage-limiting boundary for the following primary reactor containment penetrations:

1. Containment penetrations whose design incorporates resilient seals,. gaskets, or sealant, compounds, piping penetrations.fittedd with expansion bellows, and electrical" penetrationsfitted with flex)bledmetal seal assemblies.

2. Air lock door seals, including door operating mechanism penetrations which are part of the containment pressure boundary.

5200G

ENCLOSURE 3 (Continued)

3. Doors with resilient seals or gaskets except for seal-welded doors.

4. . Components other, than, those 1'isted in II.G.l, II.G.2

. or"II.G.3 .which must meet the. acceptance criteria in III.B.3.

The penetrations listed for Type "B" testing are required by the regulation cited above. The excluded penetrations are tested during the Type "A" test.

A number of the excluded Type "B" penetrations do have local leakage test connections. These connections can indeed be used to individually test that penetration. A number of the excluded penetrations do not have a integral test connection.

Re vested Additional Detailed Desi n/Construction Information The following listed drawings cover a full spectrum of typical penetration type, size, design features (e .g., testabi li ty) and design/construction features.

A copy of a Type "8" tested penetration (design/construction) drawing is also attached for information purposes.

'-3A, -38 .Emergency Condenser Piping .C-18359-C Testable Penetrations-Test Connections Many of the penetrations which are not subject to the Type "8" test do indeed have testable connections. These connections can be used to monitor or individually test that particular penetration. The test caps are left on during Type "A" and, therefore, they must also remain in place during normal operation. If, however, these penetrations were vented during the "A" test, then they could be likewise left open during normal operation.

~Summar The basis for the exclusion of these penetrations from Type 8 testing is directly related to the definition of containment penetrations which are subject to Type 8 testing and to the fact that they are collectively tested during a Type A test. The regulations (that is, 10 CFR 50, Appendix J, Sections II.Gl thru 4) do not require penetrations of welded design regardless of whether testable connections .are available to be, tested.

ENCLOSURE 4 CONTAINMENT SPRAY SYSTEM-HATER SEAL PROCEDURE In response to the NRC's position that the Containment Spray System isolation valve water seal feature must be established and maintained during a DBA-LOCA, Niagara Mohawk agreed to specifically establish in the current operational procedure a requirement and/or instruction to address this condition. The current Containment Spray System Procedure Nl-OP-14 is now in the process of being amended to include this as well as several other changes.

The procedure will specifically require that a water seal be established and maintained on the Containment Spray Inlet Discharge Isolation Valves for the Containment Spray loop(s) that are not in operation during a DBA-LOCA. A seal water is guaranteed in the operating loop(s) in that the loop(s) are pressurized by the operating pump and the flow of water through the system.

The NMP-1 procedure change process 'will require a formal review of the subject proposed revision. Final approval of this change is anticipated prior to startup.

A draftcopy;of .the,entire;procedure,-now ',under*modification,was given 'to the

,Resident, Inspector (William Cook);on .June',28,!;1988...When .the formal procedure revision is issued, a copy will also be given to the Resident Inspectors A copy of the new procedural instructions being added to the current NMP1 Containment Spray System Nos. 80 and 93 Operating Procedure ¹N1-OP-14 (Revision 27 dated 6/16/86) is attached.

Excerpts from American National Standard ANSl 816.34-1977 Scope This standard covers pressure-temperature ratings, dimen-sions, tolerances, materials, non<estructive examination re-quirements, testing, and marking for cast, forged, and fabri-cated steel flanged and butt-welding end valves.

Codes and Regulations A valve used under the jurisdiction ot the ASME Boiler and Pressure Vessel Code, the ANSI Code for Pressure Piping, or Governmental Regulations, is subject to any limitation of that code or regulation. This includes any maximum temperature limitation for a material, or rule governing the use of a material at low temperature.

Rating Temperature The temperature shown for a corresponding pressure rating is the temperature of the pressure containing shell ot the com-ponent. In general, this temperature is the same as that of the contained fluid. Use of a pressure rating corresponding to a temperature other than that of the contained fluid is the re-sponsibility of the user, subject to the requirements of applica-ble codes and regulations.

Materials Consideration should be given to the possibility ot graphitiza-tion in carbon steel above approximately 800 F.

r E gine Q'g:Da PIP ng-- s ASSEMBLY AND MAINTENANCE OF FLANGED JOINTS When a flanged joint is assembled, each of the component parts is subjected to tensile or compressive stresses of varying magnitude. In the great majority of cases, it is adequate to tighten the bolts sutticiently to withstand the test pressure without leakage.

The maximum allowable stress values tor bolting given in the various codes such as the ASME Boiler and Pressure Vessel Code and the ANSI Code tor Pressure Piping are design values to be used in determining the minimum amount ot bolting required.

A distinction must be recognized between the design value and the bolt stress that might actually exist or that might be needed for conditions other than the design pressure. The initial tightening ot the bolts is a pre-stressing operation, and the amount of bolt stress developed must be within proper limits to insure, on the one hand, that it is adequate to provide against all conditions that tend to produce a leaking joint and, on the other hand, that it is not so excessive that yielding of the bolts and/or tlanges can produce relaxation that also can result in leakage.

The first important consideration is the need for a joint to be tight in the hydro-static test. An initial bolt stress of some magnitude greater than the design value therefore must be provided. It it is not, further bolt strain develops during the test which tends to part the joint and thereby, to decompress the gasket enough to allow leakage. It is evident that an initial bolt stress higher than the design value may, and in some cases must, be developed in the tightening operation. This practice is permissible, as pointed out in Appendix S, Section VIII, Division 1, of the ASME Boiter and Pressure Vessel Code, provided it includes necessary and appropriate provision to insure against excessive tlange distortion and gross crushing of the gasket.

Investigation of field-erected tlanged joints has indicated that the probable bolt stress developed manually, when using standard wrenches on a//oy steel bolts is:

S= 45,000

'd where S is the bolt stress and d is the nominal diameter of the bolt.

Experience indicates that these stresses are satisfactory for ANSI B16.5 flanges and will comply with the requirements as set forth in the preceding paragraphs. It can be seen that smalter bolts wilt have excessive stress unless judgment is used in pulling up on them. On the other hand, it will be impossible to develop the desired stress in very large bolts by ordinary hand wrenching. Impact wrenches may prove serviceable, but if not, resort may be had to such methods as preheating the bolt or using hydraulically-powered bolt tensioners. With some of these methods, control of the bolt stress is possible by means inherent in the procedure, especially if effective thread lubricants are employed, but in all cases, the bolt stress can be regulated within reasonable tolerances by measurtng the bolt elongation with suitable extensometer equipment. Generally, simple wrenching without veritication of the actuat bolt stress meets all practical needs, and measured control of stress is employed only when there is some special or important reason for doing so.

It is possible for the bolt stress to decrease after initial tightening, because ot sloe creep or relaxation ot the gasket, particularly in the case of the "softer" gasket materials. This may be the cause of leakage in the hydrostatic test, in which case it may suffice merely to retighten the bolts. A decrease in bolt stress can also occur in service at elevated temperatures as a result of creep in the bolt and/or tlange gasket material, with consequent relaxation. When this results in leakage under service conditions, it is common practice to retighten the bolts, and sometimes a single such operation, or perhaps several repeated at long intervals, is sufficient to correct the condition.

/HAPjVj+N QQL+Es o types oi body and bonnet connections clanged (with 'gasket)

For many years, all steel valves were designed and built with flanged body and bonnet con-nections. These connections were gasketed and bolted tightly to prevent leokage. This design proved entirely satisfactory while temperatures remained below 700 and in fact, it is still quite generally used in the lower pressvre-temperature range. Improvements in bolting materials have mode practical the use of the flanged design for temperatures of approxi-mately 925'F.

As pressures and temperatvres increased, some difficvlty was encovntered with bolting rnoterial, which had a tendency to stretch and allow Fi)ANGED CONNECTION WITH GASKET leakage at the bonnet flange. In an attempt to solve this problem, various designs were This cross section shows connecting body developed, such as the Sargol joint which uses and bonnet Ganges, with gasket inserted.

Flanges are bolted tightly together to a bead of welding for sealing; the ring joint prevent leakage.

with a special gasket configuration; the Hovston joint with calculable gasket area; and the spiral-wound metal, asbestos filled joint with inherent resiliency. All of these have been, in a measure, successfully used.

welded design In l936, Chapman introdvced the first all-welded body and bonnet joint. Valves assem-bled by this method are still giving trouble-free service.

~ The welded body and bonnet joint has the decided advantage of not relying on bolting or other materials which can relax and cause leakage. It is also light in weight and reduces hanger loads. There are no gaskets used simply a completely tight weld of the body and bonnet. To our knowledge, we have never had RING JOINT leakage in a welded body-bonnet valve.

the seats welded into the body, there is hardly ever the necessity for opening the bonnet joint of gate valves. When major repairs are re-quired, the valve is simply cut from the line and returned to !he factory where a special parting tool opens the bonnet joint.

a.

PreSSuX'e Seal In the never-ending search for better design, valve manufacturers turned to a type of joint which had found success on feed water heaters in Europe, on gun recoil mechanisms, and similar u'ses. This design was modified and applied to body-bonnet joint connections under the de-scription "pressure seal".

The pressure seal joint consists of a body and bonnet with a triangular-shaped seal ring which

' "makes up" against the body and bonnet. In Chapman construction we weld in stainless seats where the pressure seal ring seats against both the body and the bonnet. The material utilized in this seat is a material which has found WELDED JOINT wide acceptance for the main valve seat. Due No bolts or gaskets are used with this to the nature of the joint, it is self-energizing; type of connection. Body and bonnet however, because the valve must be tight not are welded tightly together, making a leak-proof joint. only at its designed working pressure but at t

p5 reduced pressure, a means must be provided to preload the pressure seal ring in order to maintain tightness when operating at reduced pressure.

The pressure seal joint has the advantage of being light in weight, and cosy to toke opart for cleaning the inside of the valve. It does, however, have the same problem as the bolted joint, in that it is subject to relaxation. This is minimized by the ease with which it may be "taken up".

II II l There is also some problem due to the seal

'I energizing joint and the fact that high pressure valves are tested to 3'/z times the rating work-ing pressure, which tends to distort the sealing edge of the pressure seal ring. Moreover, before instollation, valves are re-tested at the site at the pipe code rote, I'/z times working pressure, which again tends to overstress the pressure seal joints. This necessitates taking up PRESSURE SEAL on the joint, which is usually done by measuring the torque applied to the bolts to bring them Body and bonnet joint is self-energizing and is assembled with a special seal back to the original factory seating. Once the ring. Provision is made for initial pre valve is in service at line temperature, it should load and take-up on the joint by the use again be checked to be sure the joint has not of adjustable alloy bolts.

relaxed. From this point, an annual check is usually sufficient.

Welded or pressure seal type valves are always supplied with welding ends.

0 ATTACHMENT TO ENCLOSURE 4 ADDITIONAL REQUIREMENTS BEING ADDED TO Nl-OP-14 Add the following to the Off-Normal Procedures Section:

H. Off-Normal Procedures (Cont.)

Establishing A Hater Seal On The Containment Spray Discharge Isolation Valves.

NOTE: This procedure is to be performed if a Loss-of-Coolant Accident (LOCA) occurs. A water seal must be established on the Containment Spray Inlet Discharge Isolation Valves for the Containment Spray loop(s) that are not in operation. Per Appendix 3 of 10 CFR 50, this water seal must be maintained for a minimum of thirty days to prevent any radioactive release through these lines.

l. If no Containment Spray pump is in operation, THEN start the Containment Spray System in the Torus Cooling Mode of operation, using one pump, per the Off-Normal section of this procedure (paragraph H.5.0, page 1:later]).

2. Shut the following. valves for the loop(s) that are not in operation in the Containment S ra Mode:

~Loo Containment Isolation Valve 111 CTN-SP Inlet IV-111 112 CTN-SP Inlet IV-112 113 CTN-SP Inlet IV-113 114 CTN-SP Inlet IV-114

3. Cross-connect the idle loops of Containment Spray with the operating loop by opening, or verifying open the following Bypass to Torus valves (one of the valves will already be open if in the Torus Cooling Mode):

BV-AOV-80-40, Bypass to Torus for Loop ¹111 BV-AOV-80-41, Bypass to Torus for Loop ¹121 BV-AOV-80-44, Bypass to Torus for Loop ¹112 BV-AOV-80-45, Bypass to Torus for Loop ¹122 5200G
