INTRODUCTION
[ As a result of a self assessment performed on Millstone Unit No.1 Technical :
Specifications (TS), it was determined that the neutron monitoring requirements needed ,
j to be modified. Amendment 34 dated November 19,1976 added an APRM startup ;
- High Flux reactor scram but did not remove the unnecessary RUN Mode IRM High ,
Flux / Inoperative with the associated APRM downscale scram Trip Function (IRM RUN i i Mode SCRAM). The IRM RUN Mode SCRAM existed on several early BWR plants including Millstone Unit No.1. It was deleted by General Electric (GE) on later BWRs l
. because it was not seen to be performing any function commensurate with its required i 1 surveillance. in consideration of this surveillance difficulty, and the doubtful contribution which was made to the overall neutron monitoring protection system, GE decided to eliminate the IRM RUN Mode SCRAM on later plants. GE has performed a ;
Millstone Unit No.1 evaluation and has concluded it is a logical step to remove the i requirement for this scram function from TS at Millstone Unit No.1, consistent with the action taken at other contemporary plants. Finally, miscellaneous changes are proposed involving editorial revisions and clarifications.
3 The proposed amendment is designed to eliminate the above identified weaknesses by using appropriate GE design requirements pertaining to neutron monitoring and i adopting appropriate improved Standard Technical Specifications (STS), NUREG i 1433, " Standard Technical Specification General Electric Plants, BWR/4," Revision 1.

U.S. Nuclear Regulatory Commission B16407 Attachment 1\Page 2 SAFETY ASSESSMENT The preface to NUREG 1433 describes the development of the improved Standard :
Technical Specifications (STS) for General Electric (GE) BWR/4 plants. This NUREG is the result of extensive public technical meetings and discussions between the Nuclear Regulatory Commission (NRC) staff and nuclear power plant Licensees, Nuclear Steam Supply System (NSSS) Owners' Groups, specifically the GE O.vners' Group, and the Nuclear Energy institute (NEI). NNECO proposes to adopt related requirements, as applicable to the licensing basis of the facility, to achieve a high degree of standardization and consistency.
These proposed Technical Specification (TS) changes are consistent with the above recommendations and applicable to Millstone Unit No.1 licensing basis. Minor word additions / differences from STS are required to provide consistency with current TS wording and support the current licensing basis. These minor word additions / differences do not alter the meaning of neutron monitoring requirements from the STS or change the current licensing basis. Exceptions to STS principles were necessary to meet the current licensing basis and current format of existing TS.
Although the IRM High Flux and inoperative Trip Functions in RUN are listed as an RPS scram (RPS LCO Table 3.1.1), they do not directly initiate a reactor scram. The trip performs an interlock function associated with the APRM downscale trip initiation.
The interlock prevents the IRM High Flux / Inoperative scram function from being defeated in the RUN Mode until the APRM downscale setpoint has cleared (> 3/125 full scale).
The bases for removing the RUN Mode IRM High Flux / Inoperative with the associated APRM downscale scram Trip Function (IRM RUN Mode SCRAM) from TS is presented in a General Electric (GE) evaluation performed for Millstone Unit No.1. This function existed on several early plants but was deleted from later plant designs. UFSAR and reload safety analyses do not take any credit for the IRM RUN Mode SCRAM lt is no longer required by the STS and has been deleted from Technical Specifications of several plants that originally included it in their design.
Removal of the IRM RUN Mode SCRAM from TS will permit available combinations of !
inoperable IRM and APRM channels to be simultaneously bypassed, as intended by 1 the plant design (UFSAR 7.2.1.1.1). Due to a differing number of APRM and IRM instrument channels (six vs. eight), some IRM channels share the same APRM channel in the APRM downscale logic. Consequently, some bypass combinations of inoperable IRM and APRM channels would result in less than the minimum number of required operable IRM RUN trip functions, precluding bypass capability for one of the inoperable channels. Under these circumstances, the plant must remain in a " half scram" condition. Removal of this trip function from TS will avoid the need to operate the I

' I U.S. Nuclear Regulatory Commission B16407\ Attachment 1\Page 3 i
plant in the " half scram' condition, with the associated risk of a plant transient, for i certain inoperable IRM/APRM combinations.
Removal of the IRM RUN Mode SCRAM function and associated Notes from the Technical Specifications is not a safety concem for the following reasons:
a) The design basis accident in this region of operation (RUN Mode) is the control rod drop accident (CRDA). The only scram function that the UFSAR takes credit for in the mitigation of the CRDA is the APRM 120% power scram.
b) A Continuous Control Rod Withdrawal error (CWE) in RUN is terminated by the i Rod Block Monitor (UFSAR 15.5.1). The APRM Reduced High Flux scram in i conjunction with the IRM scram limits the consequences of the CWE during the STARTUP Mode, i
c) If the modo switch is changed to the RUN Mode prematurely during a hot or cold i i
startup, the control rod block associated with the APRM downscale trip will activate, precluding further control rod withdrawal. The control rod block feature ,
i i is required by the TS Table 3.2.3, and is not altered by the requested change.
e d) If the reactor power is reduced too far before changing the mode switch to the STARTUP Mode, the control rod block associated with the APRM downscale trip ,
will activate, precluding control rod withdrawal. Also, procedures require IRMs to be fully inserted prior to changing modes from RUN to STARTUP and if the :
l lRMs are not fully inserted, a control rod withdrawal block would be activated
- after the mode switch was placed in STARTUP.
i e) In addition, during a cold plant startup, prematurely changing to the RUN mode will result in MSIV closure due to insufficient steam pressure and subsequent scram if the reactor vessel pressure is 5 825 psig.
) Further revisions were made to LCO 3.1 Reactor Protection System Table 3.1.1 and
- associated TS Bases to clarify APRM Trip Functions and align the Table with TS i Section 2.2.1. These revisions do not alter the intent for neutron monitoring 3 1 requirements.
The RUN requirement and associated Action B for Reduced High Flux trip function requirement is an editorial error introduced when Amendment 34, dated November 19, 1976, was issued. Amendment 34 revised TS to reflect a hardware modification to install an APRM Reduced High Flux . scram trip function in 6.he REFUEL, SHUTDOWN, ,
- and STARTUP/ HOT STANDBY Modes. This trip function is not required and is automatically bypassed in the RPS logic with the mode switch in the RUN position. .
Also, the requirement for the APRM Flow Biased High Flux trip function to be operable in the REFUEL, SHUTDOWN, and STARTUP/ HOT STANDBY Modes was not required i
. ~ , -
U.S. Nuclear Regulatory Commission B16407\ Attachment 1\Page 4 because the required neutron trip functions in these modes are provided by the APRM J Reduced High Flux and IRM scram functions (which actuate at a lower power than the ;
Flow Biased High Flux trip). TS Section 2.1.2, Fuel Cladding integrity APRM Limiting Safety System Settings, correctly identifies mode requirements for these settings which l are described in the associated bases. ;
4-Addmg a new surveillance requirement to RPS Table 4.1.2 and corresponding description to the associated TS Bases to verify SRM/lRM/APRM overlap is being t
proposed to ensure that no gaps in neutron flux indication exist from subcritical to power operations. The overlap between SRMs and IRMs is required to be demonstrated during reactor startup, to ensure that reactor power will not be increased ,
into a neutron flux monitoring region without adequate indication. On power increases, >
the system design will prevent further increases (by initiating a rod block) if adequate overlap is not maintained. The overlap between IRMs and APRMs is of concern when reducing power into the IRM range. Overlap between IRMs and APRMs exists when sufficient IRMs and APRMs concurrently have onscale readings such that the transition !
between the RUN and STARTUP/ HOT STANDBY Modes can be made without either APRM downscale rod block, or IRM upscale rod block. This proposed change is -
consistent with STS requirements. !
As discussed above, Northeast Nuclear Energy Company (NNECO) concludes that the ,
proposed changes to a) remove the RUN Mode IRM High Flux / Inoperative with the !
associated APRM downscale scram Trip Function; and b) incorporate editorial revisions to conform the Technical Spacifications to the actual design is safe and justified. These changes will enhance general understanding of neutron monitoring TS surveillance requirements for Millstone Unit No.1. The proposed changes clarify the requirements already existing in the Millstone Unit No. 1 current Technical j Specifications for surveillance, and adoption of appropriate improved STS wording ensures standardization and consistency with industry practices. !
I Consistent with these factors, the NRC has approved similar amendments incorporating ,
the above changes. Amendment No. 50 dated August 26,1987 to Facility Operating !
, License No. DPR-22 for the Monticello Nuclear Generating Plant deleted the IRM RUN l Mode SCRAM. Also, Amendment No. 227 dated September 11,1995 for the James A. l FitzPatrick Nuclear Power Plant removes the IRM RUN Mode SCRAM 1

! The proposed changes affect only the operations of neutron monitoring and protective systems (IRM and APRM) which provide indication and mitigation 3
actions only. Operation of these systems does not create the possibility for new ,
precursors (such as reactivity) which would introduce a new or different kind of ;
occident from any accident previously evaluated.
Additionally, the proposed changes do not affect the ability of those systems t required to mitigate previously evaluated accidents during the modes they are credited. ;

t J i The only scram function that the UFSAR takes credit for in the mitigation of the ;
limiting accident (control rod drop accident) is the APRM 120% power scram which is not affected by this change . Only the IRM RUN Mode SCRAM, for
- which the UFSAR takes no credit in the termination of any analyzed event, is
. removed by this change. Removal of the IRM RUN Mode SCRAM will avoid the ,
4 need to operate the plant in a " half scram" condition with the potential for an ;
inadvertent plant transient. For these reasons, the change does not involve a significant reduction in a margin of safety. .
The Continuous Control Rod Withdrawal Error (CWE) transient is terminated by the Rod Block Monitor (RBM) in the RUN Mode. When initiated from the i STARTUP Mode, the consequences of a CWE are limited by the APRM Reduced High Flux scram in conjunction with the IRM scram function. Therefore
- eliminating the TS requirement for the IRM RUN Mode SCRAM will not reduce the margin of safety for this transient.

Adding a new surveillance to verify SRM/lRM/APRM overlap will enhance reutron monitoring during startups and shutdowns and consequently does not involve a significant reduction in a margin of safety. I Therefore, based on the above evaluation, NNECO has concluded that these changes do not involve a significant hazards consideration.
