STEP DESCRIPTION TA8LE FOR ECA-3.1 STEP 10 Correl a44 S +u EPPGZo Sfgp k4 STEP: Initiate RCS Cooldown To Cold Shutdown PURPOSE:. To begin or continue a controlled RCS cooldown to cold shutdown temperature as quickly as feasible in order to minimize total leakage of reactor coolant BASIS:
The RCS must be cooled and'depressurized to. cold shutdown conditions as quicklyg as possible to minimize both leakage of reactor coolant. and radiological eleases from the ruptured steam generator. This step establishes a 100'F/hr cooldown rate, which balances the need for rapid RCS cooldown with the concern of pressurized thermal shock of the reactor vessel. The preferred method is, steam release from the intact steam generators to the condenser since this conserves feedwater supply and minimizes radiological releases. If steam dump to the condenser is unavailable, atmospheric steam releases via the intact steam generator PORVs provides an alternative means of cooling the RCS. In the unlikely event that no intact steam generator is available, one must select either a faulted steam generator or ruptured steam generator to cool the RCS until the RHR System can support further cooldown t'o cold shutdown.
I ACTIONS; 0 Determine if RCS cooldown rate is less than 100 F/HR 0 Use RHR system 0 Dump steam to the condenser from intact SGs 0 Dump steam from intact SG PORVs 0 Dump steam from intact SGs by other plant specific means 0 Control feed flow to faulted SG to cooldown RCS 0 Dump steam from ruptured SG INSTRUMENTATION:

'There are two rod deviate.on alarms fed by DR?I. One is, a local rod deviation alarm on the DRPZ panel on AEP-1. The attached table 6.6 fr'om SD-104, "Rod Control System", shows that this alarm is driven bv either a shutdown rod at or below 210 step.=., or any two rods in control bank d'ffer b'reater than or equal to 12 steps. A second alarm fed by DRPI'is the "Rod Dev/Seq N1S Power Range Tilts" alarm on Ma'n Control Board ALB 13 window S-5. The attached pages rom RODCS-LP-3.1 indicate this alarm actuates on rod out of sequence,

NRC QUESTION 3.31 List the four (4) sources of control signals which are used by the SGLCS to positioh the feedwater flow control valves. (0 '.5 each)
ANSWER 3.31
- 1. Steam generator level (0
- 2. Feedwater flow
'5 each)
- 3. Steam flow
- 4. Power demand level or reference level (first stage turbine pressure or reactor power) ~
CP&L COMMENT The above answer omitted another source of a signal for use by SGLCS. Steam pressure is used for density compensation 'of the steam flow signal. Th~s 'is shown in the text of SD-126.02 on page 9 (attached) and in figure 7.2 of the same SD. Since the question asked or signal sources, then steam pressure is an acceptable respons=. It actually has more impact on SGLCS operation than first stage turbine pressure since we operate with a constant programmed steam generator water level of 66'.".
RECOMMENDATION Accept steam alternate answer. This results in having "o l'st presSure as four answers an per the question statement out of five possible al"ernatives for an acceptable response.

OS3 4.1 Normal Operations (continued)
The summation of the pressure and momentum effects is shown in Figure 7.8. The SGWLCS will act to maintain SG level at 66Z level after these transients. The SGWLCS is designed to reduce the size and length of the level oscillations. Thus, normal level oscillations are within the bounds of reactor trip at the low-low SG level and turbine trip at the high-high SG level.
During normal operation (15<<100X power) the SGWLCS provides automatic SG level control by using a three element controller which senses steam flow, feed flow, and SG level (Figure 7.2).
The ste flow sed and corrected E densit b a steam summer. A flow error signal is produced by subtracting the feed flow signal from the steam Elow signal ~ The flow error signal.
goes to a proportional plus integral (PI) controller.
The level program receives an input from the turbine impulse pressure transmitter. The impulse pressure signaL is multiplied by zero and 66 percent is then added to give a constant Level Program of 66 percent regardless of power level (Level program ~
zero x Pim + 66 percent).
Actual SG level is sent through 'a lag circuit to dampen out natural., oscillations in the level signal. A level error signal i.s produced by subtracting actual level from program level.
The level error signal is sent to the PI controller. This PI controll'er allows level to dominate over the flow error signal.
It also eliminates steady state level and flow errors. The level and flow error signals are added to produce a total error signal. This total error signal is the output of the PI controller when it is in AUTO. The output of the controller can be manually controlled by the operator. The output then goes to the IP converter to position the FW control valve.
4.2 Start-U and Shutdown 0 erations Start-up and shutdown operation is considered low power operation, so the feedwater bypass control. system (see Figure 7.3) will be used. It will give stable level control. from 0-25Z reactor power. Normally the change over, point to and from the main Eeedwater control system will be at about 15Z power.
This system shares the level program and level detectors with main FW Control System. In place of a flow error signal, the FW Bypass Control System uses nuclear power channel N-44 as an input of anticipated steam demand. This arrangement is used because the flow signals are unstable at low power levels and transient response.

OS4 4.3.2 Main Isolation"'(MSIS) (Fi ure 7.28) (continued)
'zovided on MCB. Main steam isolation is addressed in SD-l26.
The steamline isolation signal also enables auxiliary feedwater isolation.
4.3.3 Auxiliar Feedwater Isolation (Fi ure 7.29)
Auxiliaz'y feedwater isolation is derived from the main steamline isolation coincident with a high steam line differential pressure (hP). When low steamline pressure is detected in one loop, that loop's auxiliary feedwater line is isolated.
4.3.4 Main Feedwater Isolation (MFIS) (Fi ure 7.24)
A Main feedwater isolation consists of closure of the main feedwater valves, the feedwater isolation valves, the feedwater bypass valves, and tripping of the main feedwater pumps and the-turbine. The MFIS is derived from an SI signal or a two out of four Hi-Hi steam generator signal (P-14) Reset of the bypass
~
valves and main feedwater isolation valves is accomplished by the Train A and Train B reset switches on the MCB. Closure of only the main feedwater valves will automatically occur when the reactor is tripped (P-4) and a two-out-of-three low Tavg signal occurs.
4.3.5 Containment Isolation SA (T) (Fi ure 7.30)
Containment isolation SA results from either a safety injection signal (Figure 7.27) or from manual actuation of either of two MCB switches. Reset of the T signal is accomplished by actuation of the Train A and Train B Containment Isolation 8A Reset MCB switches. See SD-114 for more discussion.
4.3.6 Containment Ventilation Isolation (CVIS) (Fi ure 7.30)
Containment ventilation isolation results from a 5A containment isolation signal, safety injection signal (Figure 7.27), from a Manual Containment spray actuation signal (Figure 7.31), or a high radiation signal fzom the Radiation Monitoring System containment radioactivity detectors (RM-1CR<<3561A, B, C, & D). The CVIS signal can be reset by the Train A and Train B Containment Ventilation Isolation Reset switches on the MCB. See SD-114 for more discussion. (See Section 4 ')
4.3.7 Containment S ra (CSAS) (Fi ure 7.31)
Containment Spray results from either a two out of four, Hi-3 containment pressure, or simultaneous manual actuation of either group of two MCB switches. The CSAS signal can be reset by the Train A and Tz'ain B Containment Spray Reset switches on the MCB.
It is noted that the manual spray actuation controls also initiate Containment Ventilation Isolation and Containment Isolation Phase B. Reference SD-112.

ENCLOSURE 4 NRC RESOLUTION OF FACILITY COMMENTS RO Examination guestion 2.14 NRC resolution: Comment accepted. guestion deleted from exam.
Section and total point values adjusted accordingly.
guestion 2.21 NRC.resolution: Comment not accepted. The facility comment correctly references the basis for the initiation of RCS cooldown to Cold Shutdown.
The question asked for the basis of the CAUTION preceding this step. The CAUTION addresses the reason for terminating the SI as quickly as possible "after the cooldown has been initiated". By looking at the entire Step Description for ECA-3. 1 step 10, (facility only referenced the first page) the KNOWLEDGE portion describes verbatim the reason for this CAUTION. It should also be noted that this question was written by the facility representative during the exam pre-review.
guestion 3.29 (a)
NRC resolution; Comment not accepted. Each alarm in the question is clearly identified by the use of quotation marks indicating the actual wording of each alarm. The alarm referenced in the facility corrment, which would make 85 a correct response for (a), is the "Rod Dev/Seq NIS Power Range Tilts" alarm. The question asked for the "RPI Rod Deviation" alarm.
guestion 3.31 NRC resolution: Comment partially accepted. As shown in the reference provided the P. I. controller in the SGLCS takes input from two comparators: Flow error (compensated steam flow - feed flow) and Level Error (actual level - program level). Since steam pressure is one parameter that is used to determine compensated steam flow, it will 'not be counted as an incorrect answer. However, to receive full credit all signals as mentioned in the answer key must be listed.
guestion 3.35 NRC resolution: Comment accepted. Answer was taken from CVS-LP-3.0 p.23 which is in error. Answer key changed to reflect facility comment. Each response will be worth 0.375 vice 0.5.
ENCLOSURE 5 SIMULATOR FACILITY REPORT Facility Licensee: Carolina Power and Light Company Facility Docket No.: 50-400 Operating Tests Administered On: August 22 - 24, 1989 During the conduct of the simulator portion of the operating tests, the following items were observed:
ITEM DESCRIPTION Main Feed It was not possible to override the automatic trips Pumps associated with the Main Feed Pumps.
During a scenario in which both Main Feed Pumps were lost, the simulator went into a loss of all AC unexpectedly. This pr'oblem was reviewed and corrected while the exam team was still on site.
On two occasions the simulator froze during the running of the exam scenarios.
This effected the exams in that it detracted from the sense of realism.
