'I:

2.0 SYSTEM DESCRIPTION .

'i{

E*

2.1 The purpose of the Safety Parameter Display is to assist control room personnel in the evaluation of the safety status of the

!lE pl ant. The SPDS shall be continuously available during all modes

E of plant operation including cold or refueling shutdown, heat up

!! and cool down, power operation, and abnormal transient conditions.

Very abnormal conditions', such as Inadequate Core Cooling (ICC),

jg

. shall be displayed. The SPDS shall be designed to use a minimum l

![, number of displays and parameters, yet be able to concisely alert ;

2i the operator to abnormalities of:

$8 (1) Radiation Release rkl

-4 (2) Core Heat Removal and Core Cooling (3) Reactor Coolant System Integrity .

Ei: (4) Containment Integrity j.i (5) Reactivity 0

l2 The SPDS shall serve as an operator aide and shall be used by the 8l[= j, operator to quickly focus on confined abnomal areas thus limiting y3i the number of control room indicators to be reviewed for further

,ji monitoring. This system shall meet the requirements of NUREG-0737 l i

t Supplement 1.

,i:

g ji8 ,

2.2 Features

i; y': . 2.2.1 The SPDS shall display sets of parameters or derived '

"!p variables from which the overall status of the plant may l 8

g be determined.

i .: 5 i!; 2.2.2 All displays shall be on two (2) color video monitors.

A r8 igj 2.2.3 The SPDS displays are described in Section 3. Detailed descriptions of the displays are in Appendix 1.

i 3.1.1 Low Temperature / Pressure P-T (Figure 1-5) g!*

Used during the early stages of heat up, the later 22{

g stages of cool- down, and may be used during refueling.

'13 To be displayed per loop (i.e, for two-loop plant - two

I di spl ays) .

5';.

3.1.2 Post Trip ("ATOG") P-T (Figure 6-10)

I.

EE Used af ter trip and during heat up and cool down. Used

$s for evaluation of abnormal reactor steam system

=i transient. Used to monitor the effects of operator i

!; corrective actions. To be displayed per loop. (AT0G =

Abnormal Transient Operational Guidelines).

g 3.1.3 Power Operation (Figure 11 & 12) ,

l The reactor protection system envelopes are shown.

M)l E i These envelopes are used to show reactor and reactor jgi coolant system performance with respect to normal

I limits. One display will be shown per figure.

,3 The alert conditions are defined in B&W Drawing # 51-1121942.

.jg When an alert tests true, an alert signal will appear on the I,o screen of the SPDS to " KEY" the operator to ancrnalies in areas not gj rigorously monitored by the SPDS. The alert signal on the screen

" will be limited to nine alphanumeric characters and will flash

The alert will clear automatically when the i;! acknowledge pushbutton is pressed and the alert logic tests false, I'3 it will then reset and again be available for alert signaling.

ggi When an alert is flashing, a relay will be energized with a form C

j contact available at the rear of the SPDS. After the alert has

'Ig been acknowledged, it will automatically clear when the alert

j; logic tests fail .

! 3.4 Control Panel E!

!! Each of the displays are selected by a single pushbutton from the

$g control panel. In addition the low-temp and post-trip displays r have selectable curve pushbuttons. A toggle switch allows each

![ ;

SPDS to display either Loop A or Loop B parameters.

t* Drawing f 1151658 D contains the control panel pushbutton j! marking.

. =*

p 4.0 OPERATIONAL DESCRIPTION AND FEATURES ji. 4.1 System Start-Up ia2 The start-up sequence will be fully automatic. A diagnostic 3::

.j! routine will be run to verify the integrity of the SPDS computer's yj,' ROM, RAM, arithmetic processor, and control panel . Tests will gij also be done on the video generator. After the diagnostics, the

.;= SPDS system will display a test status display for approximately

,I* one minute if any test fails. The SPDS will then display the

$ I ,," post-trip "ATOG" display with history trace off. If the reactor g f;, is tripped on start-up, history trace will be on.

i; 4.2 System Reset and Loss of Power 8 g! Both of these functions are performed the same as system a .: 8 start-up.

l t..58 4.3 Control Panel Operation l y.e .

J

.as g. See B&W Drawing f 1151658 D for control panel marking. Each

= display, and some curves, on the SPDS are selected by a single 1 i, pushbutton. When a pushbutton is acknowledged, an area of the '

i;j screen associated with that button is illuminated. The display l ejw
