2.10 During the 0JT port' ion of the R0 class, EER 86-275 was implemented on Unit'1. This EER-(see attached EER) de-activates the head spray function of RHR. -Some ig students =may'not-include this in their answer.

2.11 The-timing.cycleforthe.E11-F017_valveusesa reference of 410'psig reactor pressure in conjunction- ~

with the LOCA signal. Although this is I&C level knowledge, some students may list it in their answer.

l 2.14 . Diesel engine trips not included in the answer key'but may be listed by students are: i

1. Generator / Engine Trips

a. Differential Overcurrent

b. Phase Overcurrent

c. Loss of Excitation

d. Reverse Power i These. trips were listed in an earlier revision in 200,  !

but inadvertently omitted in the current revision. -l k

4.05 The question did not specify which limits (10CFR20 or CP&L). Some students may list 10CFR20 limits and should receive credit.

f. low greater than minimum flow setpoint or hi flow.

6.3b.- Should_also-accept cooling not needed in containment.

6.14 The stem of the question may mislead students. "No valid scram signal present?"

' Answer key states " A half scram in one channel". A half scram is'a valid scram' signal.

'Other possible responses could be blown fuse or failed relay in both' g channels.

,7.16 There'is'a 5th choice.

"The assembly identification number on the fuel bundle fail are

-readable from the center of the fuel cell".

ENCLOSURE 4 SIMULATION FACILITY FIDELITY REPORT

' Facility Licensee: Carolina Power and Light Company P. O. Box 1551 Raleigh, NC 27602 i Facility. Licensee Docket No. : 50-325, 50-324 ,

Facility Licensee No.:- DRP-71, DRP-62 Operating Tests Administered At: Brunswick Steam Electric Plant Operating Tests Given On: August 25-27, 1987 ,

During the conduct of the simulator portion of the operating tests identified above, the following apparent performance and/or human factors discrepancies were observed.

Simulator Modeling Weaknesses During one exam scenario, the plant was operating near Rated Thermal Power when a trip of one Reactor Recirculation Pump was initiated. This transient result-ed in an immediate reactor scram and Main Turbine trip as a result of high reactor water level. None of the three site training personnel in the simula-tor at the time could explain how or why the simulator model responded in this way.

Simulator Systems and Simulator Facility Weaknesses l

It was noted during the visit that the Training Department was in the process of completing installation of a major upgrade to the simulator facility. In general, it appears the improvements being incorporated will enhance the  ;

fidelity of the simulator. The utility is encouraged to expeditiously complete this upgrade project so future training classes can benefit from the improve-ments. The status of the simulator as of August 24, 1987 is listed in Attachment I to this enclosure.

While the aforementioned upgrade project did not significantly hamper the .

administration of this examination, two simulator facility weaknesses were  !

noted:

1. The following malfunctions could not be inserted by the simulator instructors assisting in the examination requiring the "as planned" I simulator scenarios to be modified slightly:

Malf. No.131 - Jet Pump flow instrument failure I Malf. No. 236 - Reactor level transmitter N004A failure Malf. No. 263 - HPCI inverter failure l Malf. No. 270 - RCIC system pressure transmitter failure i

2. The annunciators on the Fire Protection panel did not provide an i audible alarm.

RPS M005 1 Scram lights added to back panel for various groups.

2 RPS test switches added to back of XV-1. Used in LEP-02.

3 RPS selector switch added to recorder panel, lower section.

4 RPS inputs to alternate pou r is now selectable using CDIG.

5 All other C0lG input for sciector switch have been removed.

APRM GAIN P0TS Six gain pcts have been added to the APRM section. All APRM test pots have been removed from switch check; the only pots are the new gain pots. These pots are selectable from IA; either the new pots or the software version. The instructor will be able to adjust the software version using CANA (NI).

TIP SYSTEM

1) TIP purge switch now causes the red light to go on/off.

2) TIP 'B' ball valve now indicates clased--always.

3) 'TIP limit switch ma,1 function will now cause high rad alarms.

FRONT PANEL MODS A0G PANEL A0G Panel is added to the system. Old SJAE system removed. 12 new malfunctions are available for the new A0G system. PROBLEM: Our core model does not make 02 and H2. An added air input has been installed in the condenser to have something for the A0G system to recombine.

Controls have been added to allow remote operations.

CR0 SDV vent and drain valves moved and backup added to panel. Valve 1) stroke time set at some ' typical' time.

2) Test switch function changed so it operates solenoid valves directly.

RPS

1) Scram Group lights added to from P603.

2) Red light will go out at correct times now on manual p/b.

T/G 1)

A new malfunction has been added; FAILURE OF THE REVERSE POWER RELAY. It will allow the T/G to run motorized for a while.

2) New pressure indicator added, scale -5 to +245 psig.

3) Range change on old indicator now 0 to +75 psig.

4)- Torus level indicators changed to -10 to +6 range. This is for both the recorder and indicator.

5) SPTMS installed and functional.

TBCCW

1) 'New malfunction added: 'line break. Response is similar to old RBCCW line break malfunction.

2) 'C' TBCCW pump can now be placed on Unit 1 using one CDIG entry in menu CC.

WELL WATER Well water #3 has been deleted.

CONDENSATE .

We can now recirc any booster pump back to the condenser by using the CDIG menu CF CDIG/CFD The black selector switch is gone. The only way to put a CDD on-line is by using CF, pages 2,3.

AUX BOILER All aux boiler alarms have been removed. The aux boiler system controls are still in place and function.

D/G

1) You can now start all four D/G engines using CDIG.

2) D/G 1 and 2 can be controlled from CDIG entries.

RWCU F042 has been changed to a maintain position switch. Be sure to check this in switch check.

l ADS

1) Valves are now two stage instead of three.

2) High drywell pressure input to ADS logic has been removed.

. 3) ADS inhibit switches added to valve logic.

CAUTIONS

.1. ' Do not use the simulator in FREEZE mode to compare what happened while ,

the simulator was running. The freeze mode is N_0T a true picture since some panel items change state when you go to freeze. Also, almost no annunciators are on in freeze.

2. On loss of RPS Bus, Rx Building Vent Dampers do not close as they should.

3. Half-153, Steam Line Break prior to restrictor causes model problem late in transient when condenser empties. (Blowsup) 1

4. Cannot activate Halfs 131, 236, 263,, and 270. I i

5. MSV #2 will not close in test.

6. Containment model blows up when going into or securing from inerting j operation.

7. CAC-AT-4409 and 4410 have not been incorporated into our models yet.

Caution tags on panel.

8. .Several (5) valves listed in procedure have not been added to Group 6 isolation. . Caution tag identifies these valves. Model-has not been modified yet.

9.- 9 meters have been added to the panel that have caution tags on them.

-These meters are not hooked up yet and are not functional. l l
