1 i l
- 8. On September 21,1989, New Hampshire Yankee ("NHY") sent a request for license l amendment to the NRC staff requesting a change in Table 3.61 of the Seabrook Unit 1 Technical Specifications, adding Penetration No. X 68 to the list of secondary containment bypass leakage l
l 3-
l i
paths.1/ 'Ihis proposed change "results from the addition of cross connect pipingfrom the Plant Instrument Air System, outside containment, to the Containment Building Compicssed Air System, ,
inside Containment." 2/ .
- 9. NHY correctly describes the function of the Containment Building Compressed Air System as follows: 3/
The Containment Building Comp:essed Air System supplies the instrument air requirements of pneumatic instruments and actuators ,
within the Containment Building. Airfor the system is supplied by two compressors located inside the Containment Building. One of the major
- components that relies on the Containment Buildmg ed Air System is the Primary Component Cooling Water (P System containment isolation valves. The operabilly of the PCCW stem is essential to the operation of the Reactor Coolant Pumps. Loss of the i Containment Compressed Air System will ultimately cause aforcedplant shutdown. 4/
- 10. According to NHY, the purpose of the license amendment is to " preclude the potential of a forced shutdown as a result of loss of the Containment Building Compressed Air .
. System", by cross-connecting a "back up" air supply system between the Plant Instrument Air i

.4/ NHY's proposed amendment and related documentation fails to enlain why failure of the Containment Building Compressed Air System will cause a forcec plant shutdown. The reason is that this system provides compressed air to air-operated containment isolation l valves for the Primary Containment Cooling Water (PCCW) system. These containment isolation valves fail closed on loss of air pressure. The PCCW system provides cooling to l
the thermal barriers on the reactor coolant pumps. If thermal barrier cooling is lost, the .
reactor coolant pumps must be shut down within 3-10 minutes to avoid pump damage. Sr.g, '

r '
i Sys:em and the Containment Air System. ff NHY also states that " plant reliability will be enhanced" by providing this backup air system. ff
- 11. As discussed in Pars.12 and 13 below, the proposed license amendment is illogical.
It will not preclude the potential for a forced shutdown because the backup air system will not be in use when the plant is in operation. Moreover, NHY provides no additional justification for its assertion that plant reliability will be improved by implementation of the proposed license amendment. In fact, the proposed license amendment adds a new source of potential containment leakage without any apparent compensating safety benefits.
- 12. The on1y way the proposed license amendment and related design change could preclude the potential for a forced plant shutdown as a result of the loss of the Containment Building Compressed Air System would be if the proposed design change were operable during Modes 14 (i.e., including power operation in Modes 1 and 2). As both NHY's proposed license amendment request and the NRC staff's related Federal Recister notice make clear, the air cross-connect will not he operable in Modes 1-4 (the air-operated isolation valve in the cross-connect line will be disarmed and the valve will be administratively controlled in the locked closed position in Modes 1-4),2/ but will instead anh be available in Modes 5 and 6 (cold shutdown and
' refueling, respectively). Accordingly. it is impossible for the proposed design change to preclude a olant shutdmvn due to failure of the Containment Building Compressed Air System since the 5/ Ibid ff New Hampshire Yankee Letter No. NYN-89116, dated 21 September 1989, from Ted C.
Feigenbaum to the NRC Document Control Desk,
Subject:
" Request for License Amendment; Plant Instmment Air Cross Connect to Comainment Building Air System", at 1.
2/ Indeed, halb NHY's " Safety Evaluation" of the proposed design change and the NRC staff's Federal Register notice state quite clearly, "Tius cross-connect will not be used during Modes 14...". Seg, New Hampshire Yankee Letter No. NYN-89116. dated 21 September 1989, from Ted C. Feigenbaum to the NRC Document Control Desk,

cross-connect will not be onerable until the olant is altendv shut down. Thus, even after Implementation of the oroposed design change, failure of the Containment Building Compressed Air System will Mill lead to closure of the air operated Primary Component Cooling Water
.(PCCW) System isolation valves, thus depriving the reactor coolant pumps of thermal barrier f cooling and necessitating the shut down of the reactor coolant pumps and the reactor. Moreover, It should be noted that the operability of the proposed air system cross-connect will have no ,
impact on the reliability of the PCCW system since this system it not even required to be 5
OPERABLE in Modes 5 and 6,8/ the only modes in which the proposed cross-connect will be available (according to NHY and the NRC staff). Hence, the asserted underlying technical i rationale for the proposed license amendment and related design change (i.e., avoiding a forced
- reactor thut down and improving plant reliability) is without a technical basis, and the proposed
= amendment and design change are illogical. .
- 13. Aside from their erroneous statement that the proposed backup air system would avoid a forced reactor shutdown or improve plant reliability, neither NHY nor the NRC staff cite ,
any other asserted safety benefit accruing as a result of approving the proposed amendment. .
-Accordingly, there is no identified benefit to implementing the proposed design change that would justify exacerbating the potential for containment leakage in the event of an accident. 2/ ;
- 14. In cur view, the illogical nature of the requested design change raises serious questions about the sufficiency of the safety analysis that was purportedly performed in support of this proposal.
8/ Seabrook Technical Specification 3.7.3.
l 2/ Although NHY plans to use an existing containment penetration, the additional equipment added to the inboard and outboard sides of the cenetration would result in an increase in l the potentialleakage paths and the likelihood ofleakage under accident conditions.

- 15. NHY seeks to effect the proposed design changes through an amendment to its low power operating license. However, the proposed amendment is unnecessary for and irrelevant to
. low power operation. In fact, the application's analysis of whether 10 CFR 50.92 is satisfied is Inddressed to conditions under full power operation. Moreover, NHY states that the cross-connect
- will not be implemented until the first refueling outage.10/ Surely NHY does not propose to
' refuel at the conclusion of low power testing, so NHY must be referring to refueling following full power operation for the first fuel cycle.
- 16. NHY's 21 September 1989 letter makes reference to a review of the proposed amendment conducted pursuant to 10 CFR 50.59 and NHY's conclusion based thereupon that the proposed amendment does not involve an "Unreviewed Safety Question". The proposed amendment is not appropriate for disposition under 10 CFR 50.59 since it does indeed require a change in the Technical Specifications. The requirements of 10 CFR 50.59(a)(1) clearly state that design changes can be made without prior Commission approval "unless the proposed change, test 4 or experiment involves a change in the technical specifications incorporated in the license or an ,
unreviewed safery question". Moreover, we do not consider the safety analysis performed by NH to be sufficient basis to conclude there is no unresolved safety question.
r
- 17. Moreover, NHY's proposed license amendment is technically flawed because it fails to address the crucial question of whether the proposed design change could increase the probability of accidents already reviewed or introduce new accidents not already reviewed; nor i does the request provide sufficient information such that the NRC staff could independently I . evaluate these matters. NHY's purported evaluation " utilizing the criteria specified in 10 CFR 50.92"is framed entirelv in terms of the consequences of accidents, and provides no discussion of i

i accident probabilities other than the unsupported statements that accident probabilities will not
'be affected. Such conclusory statements, with no stated underlying technical basis, cannot be accepted in lieu of an actual analysis. For example, NHY does not identify which accidents were evaluated (if any), their probability before and after the modification, or any other factor related to the probability of accidents end how they may be affected by the proposed design change. No basis is provided to accept NHY's conclusory statement that no significant changes in probability occur as a result of the design change.
- 18. Physically cross-connecting the otherwise independent Containment Building Compressed Air System and the ex-contaimnent air system raises systems interactions questions which have not heretofore existed. Neither the NHY nor the NRC staff provide any indication that the results of the combined failure of the systems and components served by the compressed air systems inside and outside the containment are acceptable from a safety standpoint. Indeed, neither NHY nor the NRC staff even identify which instruments, components, and systems would l
be affected by the failure of the two air systems. Since the NHY proposes to cross connect these ,
two systems, such an evaluation should, as an absolute minimum, be required, but neither NHY's license amendment request nor the NRC staff's Federal Register notice provide the slightest indication that such considerations have been addressed. Neither NHY nor the NRC staff have provided a demonstration that safety systems will not be impacted by the failure of the air systems.
- 19. In conclusion, NHY's license amendment request of 21 September 1989 (NYN -
89116) should be denied as being without technical merit and as proposing a change which would exacerbate a containment leakage path without any corresponding safety benefit. Moreover, the proposal is neither logical nor accompanied by an adequate analysis of the potential impacts of
- , the proposed changes on plant safety.

f- New Hampshire Yankee September 21. 1989 Enclosure 2 to NYN-89116 _r Backgroundt The Containment Building Compressed Air System supplies the instrument '!
air requirements of pneumatic instruments and actuators within.the
- Containment Building. Air for the system is. supplied by two compressors located inside the Containment Building. One of the major components that
. relies on the Containment Building Compressed Air system is the Primary
' Component Cooling Water (PCCW) System containment isolation valves. The operability of the PCCW System is essential to the operation of the Reactor Coolant Pumps.- Loss of the Containment Compressed Air System will ultimately cause a forced plant shutdown.
- /m
) Description of' Proposed Channes,
(_/ -i To precluds the potential of a forced plant shutdown as a result of loss
- of.the Containment Building Comprussed Air System, New Hampshire Yankee (NHY) proposes that a backup air supply be connected to the Containment Building Compressed Air System. . The back-up air supply would be a cross-connection between'the Plant Instrument Air System and the Containment Air System. The cross-connect would enter the Containment Building thru an existing Containment penetration, X-68. The penetration will be added to Technical Specification Table 3.6-1 " Secondary Containment Bypass Leakage Paths'.
The proposed change would be implemented in two phases. 'The first phase '
- is scheduled for completion prior to commercial operation and would include the installation of the cross-connect piping from the Plant Instrument Air System to the Containment Compressed Air System. The piping isolation design
- vill ~ meet 10 CFR 50, Appendix A General Design Criteria 56, ' Primary ye)
Containment Isolation' by utilizing a , fall-closed air operated valve outside L( N' j Containment and a check valve inside. Containment. The air operated valve's P
automatic open/close function will be disarmed and the valve will be L . administrative 1y: controlled in the locked closed position for Modes 1-4. The i second phase of'this change will provide the instrumentation and electrical changes. required to make the cross-connect operate automatically with Containment Air Systen low pressure and assure post-accident leolation. This phase is scheduled to be implemented prior to completion of the first refueling outage.

.e. Closing the Feedwater Control Valves .
4.
These valves are routinely tested during refueling outages. -To close them at power would adversely af fect- the operability of
.the plant. The verification of operability of feedwater control valves at power is assured by confirmation of proper operation of the steam generator water level system. The actual actuation function of the solenoids, which provides the closing function,
~
~
l-is periodically tested at power as discussed in Subsection 7.3.2.2e.
The operability of the slave relay which actuates the solenoid, which is the actuating device, is verified 'during this test.
Although the actual closing of these control valves' is blocked when the slave relay is tested, all functions are tested to assure that no electrical malfunctions have occurred which could defeat the protective function. It is noted that the solenoids work on the de-energize-to-actuate principle,. so that the. feedwater control valves will fail closed upon either the ' loss of electrical i
power to the solenoids or loss of air pressure.
Based on the above, the testing of the isolating function of feedwater ,
h control' valves meets the guidelines of Section D.4 of Regulatory i
Guide 1.22.
- f. Main Feedwater Pump Trip Solenoids I
L L No practical system design will permit full trip function testing.
l- . of the feedwater pumps without adversely affecting the safety and operability of the plant. At power, tripping of these pumps .,
would introduce a steam generator level transient, resulting in
,- unnecessary trip of the plant from low-low steam' generator level.
! Hence,.the complete trip functions will be routinely tested during re-fueling outages and/or as required by Technical Specifications.
However, the high pressure and low pressure stop valves of the feedwater turbines can be tested during power operation. A 2-way
' solenoid valve is included on each stop valve assembly. When L. energized, this allows each stop valve to be test stroked with l
the turbine in service to ensure that the stop valve stem is l' .not' stuck. - The LP stop valves are only partially closed. A limit switch.de-energizes the solenoid valve-at test position. Hence, the stop valve will move up and down through the limit switch deadband, as long as the operator holds his finger on the test push button. The HP stop valves are tested for fully closed operation if the equipment operating condition permits.
- g. RCP Motor Component' Cooling Water Isolation Valves (Close)
Component cooling water supply and return containment isolation valves are routinely tested during refueling outages. Testing of these valves while the reactor colant pumps are operating introduces an unnecessary risk of costly damage to all the reactor coolant (
pumps. Loss of component cooling water to these pumps is of 7.1-22

u, economic consideration only, as the reactor coolant pumps are not
,' ' ~ required to perform any safety-related function.
The reactor coolant pumps will not' seize due to complete loss of .;
component cooling. Information from the pump manufacturer indicates that the bearing-babbitt would eventually break down but not so
. rapidly as to overcome the inertia of the flywheel. If the pumps are not stopped within 3 to-10 minutes after component cooling water:is isolated,. pump damage could be incurred. ,
Additional containment penetrations and containment. isolation valves introduce additional unnecessary potential pathways for radioactive _ 9 Lleakage following a postulated accident. Also, since the component' cooling water flow rates and temperatures are about. equal during both plant power operation and plant refueling, periodic tests of these valves during a refueling outage would dupli'cate accident conditions.. ,
Mditionally, ' the possibility of failure of containment isolation is remote because an additional failure of the low-pressure fluid system in addition to ' failure of both isolation valves would have to occur to open a path through the containment.
Based.on the above described potential reactor coolant pump damage incurred with periodic testing of ~the component cooling water containment isolation valves at power, the duplication of at power operating conditions during refueling outages, and since 1) no ,
practical-system design will permit operation of these valves without !
adversely affecting the safety or operability of the plant, 2) the probability that the protection system will fail to initiate the ,
activated equipment is acceptably low due to testing up to final actuation, and 3) these valves will be routinely tested during refueling outages when the reactor coolant pumps are not operating, l ,
the. proposed' resolution meets the guidelines of Section D.4 of 56, af Regulatory Guide 1.22. ,
h'. Seal Water Return Valves (Close)
Seal return line isolation valves are routinely tested during refueling outages. Closure of these valves during operation would cause the safety valve to lif t, with the possibility of valve
- chatter. Valve chatter would damage this relief valve. Testing of these valves at power would cause equipment' damage. Therefore, these ,
valves will be tested during scheduled refueling outages. As above, additional containment penetrations and containment isolation valves introduce additional unnecessary potencial pathways for radioactive l
- *P release following a postulated accident. Thus, the guidelines 56 of_Section.D.4 of Regulatory cuide 1.22 are met. w-i
- 1. Chartina Header to Cold Les Isolation Valves v.
The opening of these valves during the test of the actuating protec-
,,3 tion channel would adversely affect the operability of the plant.
The, probability that the protection system will fail to open these
valves is acceptably low due to testing up to final actuation and the valves are routinely tested during refueling outages.
