l August 30, 1984 Mr. Edward G. Greenman Chief, Projects Branch #1 U. S. Nuclear Regulatory Comnission, Region I King of Prussia, PA 19406

Dear Mr. Greenman:

Thank you for the opportunity to review the Reactor Operator and Senior Reactor Operator written examinations adninistered at the Peach Bottom Atomic Power Station on August 28, 1984. We believe that both examinations were straight-forward, emprehensive and operationally oriented,and were professionally and fairly adminis-tered.

The new review process was workable and constructive, resulting in resolving the majority of our concerns through open dialogue with the examiners. After review and discussion of both examina-tions, four cmments remain.hich require additional reference material for clarification of answers. Enclosed is a list of these connents by question nunber. For each connent, specific reference material supporting the clarification is provided.

l Veraf truly yours, Richard S. Fleischmann, II Superintendent Peach Bottan Atomic Power Station cc:

'Ihis question asks the nochanisms of generating a reactor scram signal frm a Turbine Control Valve fast closure.

Cm ment: Answer key references EIS pressure frm ICT lesson plan. Lesson plan should state RETS (Relayed Emergency Trip Supply). PBAPS turbine uses Relayed EIS since drain lines are low capacity. Figure 1 to question 3.04 illustrates details of this arrangement. Answer key also discusses actuation of Fast Acting Solenoid in Control Pac. Fast Acting Solenoid is only actuated by Load Unbalance Relay (See Figure 2 to question 3.04) or last 10% of ' ICV test closure.

3.05b What are the effects of a condensate pump trip when Feed Flow is greater than 90%?

Coment: Reference lessca plan gives incorrect value to DiC load set runback triggered by the above conditions.

EHC load set runback only occurs (at 1%/sec) when total feed flow is greater than 95%. Figure 3 to question 3.05b shows the conceptual logic while Figure 4 to question 3.05b is an LER involving this circuit.

4.05c Question asks when actual Core Spray Injection to vessel would occur during a ILCA.

Coment: Answer key inplies injection would occur as soon as 450 psig injection valve pennissive is achieved.

Figure 5 to question 4.05c is provided to detail actual core spray purtp characteristics.

7.03b Question asks reason behind 50% speed limitation on running recirc punp when bringing on idle purrp.

Coment: Answer key discusses minimizing chance of APRM scram due to flow redistribution. Figure 6 to question 7.03b details consideration of vibration induced by flow reversal.

SUBJECT:

LoadRejectScram(ControlValveFirstClosure/RETSOILLOPRESSURE) s The load reject condition (tripping of the 500KV generator output breakers 215 and 225) is detected by a " POWER. LOAD UNBALANCE" Relay which is in the turbine control package.

The Power. Load Unbalance Relay compares generator amps (all three phases) to turbine cross-around pressure (see P&ID M-303 area H.3 PT-2807). Cross-around~ pressure is proportional to turbine load.

When turbine load is 40% greater than generator amps the Power-Load Un-balance Relay trips and sends a trip signal to the control valve fast closure solenoid.

In the " Tripped" condition, the fast closure solenoid blocks the RETS oil supply and dumps the oil which holds the disk dump valve closed to drain.

Rcony When the disk dump valve opens the control valve goes closed in 0.5 sec.

The pressure switch (PS) detects the decreasing oil precsure (setpoint 500 to 850 psig) before the disk dump valve opens and sends the scram signal.

Thus., this scram signal anticipates the pressure and resulting flux transient which will occur when the control valvec go shut in p.2 secondc.

I A_b__s t.ra c t 3-84-O'i On February 9, 1984, at 6:0~1 p.m.,

a runback and subsequent relay failurg in the Main Turbine Electrohydraulic Control System (EHC) resulted in a Unit 3 reactor auto scram on high neutron flux.

With Unit 3 operating at about 92% power, the 3B reactor feed pump (RFP) turbine experienced high vibration.

Manually tripping the reactor feedpump turbine caused an auto.matic runback of the recirculation pumps and the turbine EHC system.

A faulty relay l

contact in the EHC system kept the closing circuit of the main.

turbine control valves energized which resulted in a reactor auto l scram on high neutron flux.

The f aulty EHC relay and a faulty. reactor feedpump turbine coupling which was causing the vibration were replaced.

A routine test will be instituted to functionally test this relay and the EHC runback logic each refueling outage.

Description of the Event:

On February 9, 1984, Peach Bottom Atomic Power Station, Unit 3, was operating at about 921 power.

At approximately 6:00 p.m.,

the 3B reactor feed pump experienced high vibration.

The reactor operator, in an effort to decrease the vibration', reduced flow through the pump.

Vibration continued and the operator inanually tripped the pump.

The ensuing transient caused reactor water leve1 to decrease.

With feedwater flow greater than 95% and reactor water level below plus 17 inches, recirculation pump and EHC runback signals

.were correctly initiated.

The EHC runback is, designed to slowly pulse down the turbine load o

at approximately 14 per minute.

An Agastat relay (Model 2432 l

M PDC) failure caused the EHC system to runback at a rapid f

T-continuous rate.

The main turbine bypass valves opened to g

I compensate for the reduced turbine load.

When all bypass valves were fully open and the control valves continued to close, a high neutron flux auto scram occurred at 6:07 p.m.

l' i

Consequences of the Event:

l I

The Reactor Protection System functioned properly and the reactor l'

successfully auto scrammed on high flux.

Since the Reactor Protection System functioned properly and no design. limits were exceeded, the* safety consequences of this event are considered minimal.

Cause of the Event:

The cause of the event was the failure of an Agastat relay (Model 2432 PDC) in the turbine EHC runback logic.

The relay, if operating prope(

hould have decreased turbine load at approximately-1% per m.

until feedwater flow was less than 95%.

However, a contact within this relay remained closed after the EHC runback was initiated causTng a runback at a much fa=ts-rat.e and preventing the runback from stopping when it was no longer need,ed.

The cause of.the 3B reactor feedpump vibration problem was a faulty Zurn coupling.

Corrective Actions:

The Agastat relay was replaced.

A routine test has been written and will be instituted to functionally test this relay and the EHC runback logic e.ach refueling outage.

f The Zurn coupling on the 3B reactor feedpump turbine was replaced

\\.

and the turbine was returned to satisfactory service.
