PURPOSe, Ai'IO SCOPE The purpose of this docurent is to speciry the plant specific'design bas s, functional requirerents, and functional design of the QSPDS for Tur!<ey Point Units 3 and 4.

This document, in con'unction with the generic QSPOS r<.nctional design specification

',Rererence 1), comprises the func.ional desi on speci fication.

Two ot~her documents, the QSPOS data base document (Rererence 2) and the QSPDS display design document (Re<erence 3), describe the plant specific input and data constants and displays.

2.0 REFERE<ICES 1.

HPROO-ICE-3201, Revision 02, Functional Desi gn Specification or a

Qualified Safety Parameter Display Sys.em.

2.

16081-ICE-3219, Revision 00, QSPDS 'Data Base Document for Turkey Point Units 3 and 4.

3.

16081-ICE-3220, Revision 00, Functional Design Speci <ication for the QSPOS Displays for Turkey Point Units 3

and 4.

3.0 DES IGi'I BASES The design bases for the Turkey Point Units 3

and 4

QSPOS are a subset of the desi gn bases o< the generic QSPDS unctional design specification (Ref r nce 1).

Briefly, these functions are:

1.

Safety grade processing and display of the ICC variables.

2.

Isolation of Class 1E inputs into the non Class lE 'Sa<ety Assessment System (SAS) which is not in C-E scooe.

3.

Human fac.or engineered display system, 3.1 DESIG<'I BASIS E'lEi'ITS The Turkey Point Units 3 and 4 design is the sare as specified in the generic functional design of Reference 1.

4,0 SYSTE<I FUHCTIO<'IAL REQUIRE< IEi~ITS Turkey Point iJnits 3 and 4 incorporate the ICC functional require.,;ents contained in Section 4.1 of Re erence 1.

The backup SPOS function is not incluced in the Tur<ey Point Units 3 and 4

QSPOS design.

5.0 SYST

! FU<ICT.'0<Ii'L 0 SCRIP I IOH The Turkey Point Units 3 and 4 design is not oart of the standard Acc'.dent

Tne QSPOS equiOment is func ionally the same as in Reference I ~although some hardware O'I fferences r'xist,).

The QSPOS is rot connected to the Cr tical,"-<;nctiion 'Ionitor'.ng System as described in Pe=erence 1.

Tne QSPOS has a capability of accepting the following types of inputs per channel:

1.

40 high level anaiogs 2.

31 Type K thermoc"uple inputs 4.

HJTCS inputs

( 16 Type K inputs) 6.0 SYSTEll DESIGi'l REOiJIRc,i!Ei'lTS Following are the QSPOS design requirements i or Turkey Point Units 3 and 4 as compared to the generic system design requir ments in Reference 1.

6,1 OVERALL SYSTEH DESIG>l REQUIREi~l~ lTS The Turkey Point Units 3 and 4 design is the same as specified in the generic functional design of Reference 1.

6.3 Ii'(PUT REQUIREi!Ei'!TS 6.3.1 Inout List The actual list of inputs with the numbers of inputs, type of inout, range

units, and specific comments are included in the Turkey Point Units and 4

data base docurent (Reference 2).

Following is a description of the types of inputs included in the Turkey Point Units 3 and 4

QSPOS" for eacn channel as comoared to the generic functional desi gn specIfication of Reference 1.

The following cnance is made to ICC inouts as comipared to Reference 1

Hot ard cold leg temoeratur s - One hot leg and one cold leg temperature is input

six sensors in the lower section.

6.4.2 PCS Saturation llarain Three RCS saturation mar"ins will be calculated, one from each of the three loops (A, B, and C).

=ach of these three saturation margins will be display d.

The minimum subcooled margin (or maximum superheat) will be selected for display and will be used for the determination of the minimum of the RCS and upper head saturation margins.

6.5 6.5.1 OI SPLAY RE{}UIRclvc>lTS QSPOS Variable Display Information The Turkey Point Units 3 and 4 design includes the ICC detec.ion information listed in Table 8-5 of Reference 1.

Specific ranges and desi cn information for the variables are contained 1 the data base document (Reference 2).
