(In Hot Standby Mode the Steam Dumps are being controlled in Steam-Pressure Mode.)
Reducing the setpoint to 1007 psi will.cause.the , steam dumps to open to reduce pressureEO.503.. The Steam Dumps will-i close when primary temperature cools to the P-12 -(or lo-lo Tavg) 'l interlock setpoint (of 553 F)to.50]. The Steam Dumps will then 'I oscillate open and shut as-RCS Tavg oscillates around the.P-12 set / reset E0.50]. -Thus, final RCS Tavg will be approximately, 553 F (+/- 2 F)CO.503'. b.
Steam dump cperation would be blocked CO.503. (Secondary pressure R . would rise to the setpoint of the secondary pressure relief 1 valve, j 'i which would operate to maintain pressure at 1125.psig).
As a result.

The output from PT 505 is used to j perform the following functions: j o Block automatic rod withdrawal when PT 505 senses that percent turbine load has dropped below 15 percent (if selected by PS 505Z switch on MB7) o Sent to.the reactor protection system to develop the P-13 signal.
If both PT 505 and PT 506 sense that percent turbine load is below 10 percent, a signal is sent to P-7 (along with the 3 of 4 PR < P-10) to block the "at power"' trips, o Generate a reference temperature signal, Tref, (if selected by PS 505Z switch on MB7) for usage by the automatic rod j control system, temperature error circuit (Tref-Tavg) l o Generate a reference temperature signal, Tref, for usage in l [ _ the steam dump system.
Be compared to auctioneered high nuclear power for use in o the automatic rod control rate of change of power mismatch circuit (if selected by PS 505Z switch on MB7) 6.1.1.
PT 505 Instrument Failure High consider first a high failure of PT 505.
PT 505 provides an input to the Tref circuit for use in both the rod control and steam dump systems.
The Tref circuit, however, is designed with I a high limit on its output of 587 F - regardless of the magnitude of PT 505 impulse pressure.
With the reactor plant already at 100-percent power, the rod control system should be maintaining auctioneered high Tavg very close to 587 F.
Thus, no error i-35- ,

Nb36 \\f o l.. N y N % . VB . switches' associated with the PORVs and block valves, there are two " arm / block" switches,. train A and train B, on MB4.
The switches are in the " block" position during normal operating conditions and are placed'in " arm" when the plant is' cooled down.
The redundant train A and train B pressure protection. circuits
identical;-only the source of.their pressure.and temperature are inputs differ.y Temperature signals from each of the four1 hot leg wide-range RTDs (TE 413A, 423A, 433A, and 443A) are compared'. The lowest temperature is auctioneered out and used for train A actuation of PCV 455A; the' lowest reading cold leg RTD (TE 413B,. 423B, 433B, 443B) passes through a similar auctioneering unit and is used for train B actuation of PCV 456.
The two-auctioneered outputs enter their'own programming circuits.
The programmers purpose is to deve:.op a PORV pressure actuation 'setpoint as a function of RCS input temperature.
Because of the nature of the brittle fracture phenomenon, the protection setpoint automatically lower.1 as wide-range temperature lowers.
The l characteristics of tha pressure versus temperature program are , directly related to the analyzed vessel fracture limitations.
Actual reactor coolant system pressure, as measured by the wide-range transmitter PT 405 and wide-range transmitter PT-403-for train A and train B respectively, is compared to the programmed setpoint.
As actual plant prassure rises, indicating that an unsafe condition is being approached, the following cold , overpressure system events occur:
When pressure comes to within approximately 30 psi of the o current protection setpoint, a control board alarm alerts the operator to find and correct the source of the problem.
When pressure reaches the setpoint, the " armed" PORVs open o and relieve to the pressurizer relief tank.
The cold overpressurization protection system is placed in service on a plant cooldown.

i ! TO: Ken Burton { MP3 0 ra ng ppervisor aAW ~ FROM: Ron Stotts MP3 Training Supervisor SUBJECT: ' Application of Tech' Specs Objectives Attached are the general objectives for Tech Specs knowledge as approved by TPCC in September '86.
You and I discussed as early as 1984 the expectations of. station management in terms of required operator knowledge of Tech Specs.
I recommend that we revisit this important area, and that-Licensed Operators should achieve the following minimum level of Tech Specs understanding: 1) Know what items / components are covered by some LCO or another (e.g., if a name, a system, or component., the student must recognize that there is something in Tech Specs about it) 2) Be able to locate anything in Tech Specs in a minimal amount of time (I suggest 5 minutes to look anything up, read it, and tell me what is required) 3) Operators should commit to memory any action required by Tech Specs that the time frame for initiating action precludes looking it up in the book.
While this last item may appear to be associated with #2 (above), the issue is not readily disposed.
The time. frame for demonstrating the ability to use and interpret the Specs assumes that this is the only task required, no other concurrent duties.
For this reason, I believe we must arrive at guidance for Item #3 by one of the these two methods: analyze situations that could lead to entry of each a.
LCO action and determine whether or not there is sufficient time to allow reference to the book prior to taking action, or OS70 REV 3 83 BN1 .;
, .y. * Application of-Tech Spec; Objectives.
i OT3-87-030 j February 25, 1987 ' Page 2 of 2 b.
Assign a general cut-off time (as we have, traditionally done).within which we' assume.that i reference.to Tech Specs would not be convenient for any situation.
To date, we.have established-this time to be less than one hour.
I believe.we should implement the. method of the' general cut-of f. time, and perhaps ' devote attention to the other more detailed approach at a later date.' -If this..isLacceptable,1I further propose the:following modification to'our existing a criteria:
1) Operators with RO licenses should not be authorized to (or responsible-for) take actions directed by Tech , Specs from memory without direction by the'SRO in the- ' control room (i.e., SCO or SS).
For-those-required actions that are "immediate", the RO should'probably.
j have a good. understanding of what the SRO will be directing to be done; hence, to ensure our graduates of initial training have this. solid base, they should be required to memorize action statements of 15 minutes or less.
2) Operators with Senior Reactor Operator..licensep should commit to memory) as we had previously defined, actions to be taken in less'than 1 hour.t If you concur with this proposal, I will initiate the ~ required changes to our existing Tech Specs learning objectives-and present them for our joint approval as soon as possible.
