J. V. Neely Jersey Central Power & Light Company Interpace Building 260 Cherry Hill Road Parsippany, New Jersey 07054

Dear Mr. Neely:

As agreed in the Design Revision Task Group Meeting of January 10, 1969, and as further mentioned in your letter #TMI - 2/354 of January 17, we have reviewed the Gilbert Associates, Inc. and Metropolitan Edison prints of the onnel layouts and control room arrangement which were submitted to us.

A copy of Mr.

S. C. Gottilla's memorandum to Mr. P.

P. DeRienzo, dated February 6, 1969, which presents the results of the review is attached.

We conclude from this evaluation that]the{differpnces

Comparison with TMI Unit No. 1 SZwickler Tech Memo #351 pf(2) db g

We have perused the TMI #1 layout drawings and specifications (file Nos. GAI 65 through 76) made by GAI and Met Ed (and received by us to date) for the control room, panelboards and consoles and compared them'with criteria designs and layout drawings we are using for TMI #2.

The following comments are offered:

We believe separation by color to be advantageous since the-two plants, and especially their control room.2 are not identical twins.

Mr. Bartman (op. cit. ) expressed a. negative opinion about using tan.

W2 can effect a change in panel colors with some little effort, but of course this menns changing instru-ment botel colors also.

Perhaps annunciators are planmed for seine'~other location which does not show.on their drawlings.

Acknowledge, test and reset buttons are shown on console CC that might be meant for use with such annunciators.

It fis indicated in the

" Requirement Outline" spec. that amber ligjhts are to be used for abnormal alarm conditions.

We believe: that the~use of annunciators is necessary. /

10.

The TMI #1 drawings show an operator Tr. nee recess in the console.

Unit #2 does not include such rescess.

For example, on the left side of console CL,- there are 6-S3-1. switches (No. 214, 217, 220, 223, 226 and 227) arranged in a wertical row on the lower portion of the console.

Each of thease has 2 or 3 associated indicating lights of GE type ET-16 which are presumably to be located directly above the switches.

If wie assume no separate name plates, but that the lengends are put on the switch escutcheon plate, then with'a console face height of 29" (and neglecting framing at the edges and clearance between switch I

cases), this leaves less than-5" per switeih and associated lights.

Since the switch case alone has a vertical height of 4 7/16", this is patently impossible.

The only way that all of the control switches can be, acco=odated on the layouts sho.m is by the 'use:..of GE-SBM ortsiinila[siO~itchesUwhich~ars]

P. P. DeRienzo February 6, 1969 Page 4 Accommodation of SB.1 switches in our design would require considerable redoing of our drawings.

12.

On TMI #1, motor and switchgear control' switches are GE type SB-1 but valve control is by illuminated push-buttons manufactured by Master Specialties Co.

On TMI #2, all control is by GE-SBN switches.

We can change to MSC pushbuttons for p h

valve control but at considerable cost in manhours.

However,y'

'this might save some panel space.

13.

In' Unit'#2, we make extensive use of Cutler-Hammer model E30 compact pushbuttons and lights which are heavy-duty and oiltight.

Unit #1 uses GE CR-2940 pushbuttons (which are heavy-duty, oiltight), Bailey RZ and MSC pushbuttons, neither of which seem to be heavy-duty, oiltight.

We can' change to.p,,>'

their usage but at some cost in manhours.

t/#

14.

Some of the switches on the unit #1 vertical panels seem too high (above 6 f t. ) for convenient operation.

(This state-ment assumes that the layouts as shown aro roughly to scale.)

/ 15.

No. 1 unit uses GE type ET-16 indicating lights.

No. 2 considertheseroughlyPh,.

unit uses Westinghouse "Minilite".

W:

equivalent and can change to ET-16 with sor.e small effort.

16.

The spec. for Unit #1 panels calls for vibration mounts.

In Unit #2 we had concluded (for the OC lo cation) that rigid mounting to the curbs would better serve our seismic require-ments.

This may change if necessary to accorr.odate aircraft impact criteria.

If we were to switch to edge-wise meters, the cost in manhours would not be inconsiderable.

20.

The Unit #1 panels have provision for the Amertap system.

Now that Unit'#2 is adopting this system, we will make similar provlsions.

21.

It appears that TMI #1 has made no provision for temperature monitoring or recording, although there is a backup scanner shown on the PLF panel v!hich,may be for temperature monitoring.

(It 'may :be? that' relianceforL thsse Lfunc_ti'ons has been placed on

the' computer, which we #5 ave regarde'd'as strictly idiunctiva'l.

i We believe temperature. monitors and/or recorders Eto be. necessary N

, for proper; operation.

22.

'No. 1 panels have Powdex instrumentation and controls.

We

'have no such requirements in the Control Room for our mixed-bed system.

23.

The Unit #1 consoles have a 19" height for their backfaces.

Ours is 16".

No purpose would be served, at present, in in-creasing this.

And, of course, this limits visibility of the vertical panels.

24.

The " spec" for unit #1 calls for hot rolled steel for the panels.

We call for cold rolled steel for the panel faces, which yields smoother finishes with less mill scale, etc.

Unit #1 spec. allows for1/8" steel plate where instrument density is not high.

We call for 3/16" plate on all faces, since we 'believe 1/8" is not rigid enough.

25.

No. 1 spec calls for " laminated" nameplates, glued on.

W2 specify, for Unit #2, Ply-Vinyl type nameplates, screwed on.

Experience has shown that glued nameplates can fall off with time and with temperature changes.

The Ply-Vinyl type we believe to be superior to front-engraved laminated plastic namcplates, because they are back-encraved and have no dirt-catching letters or numerals on the front.

The review of the layout drawings gives rise to some questions which prevent more complete evaluation.

They follow:

1.

B&W will supply Unit #2 with a CRD panel (Our No. 1.4).

Is this the section shown on the drawings as a vertical panel directly behind console CC and designated "by B&W"?

2.

Khat is the vertical panel "PRF-by others"?

and who are the others?

3.

TMI el drawings do not show a relay or cable room, but surely there mus t be one.

hhat does it contain and where is it located?

Is the " Requirement Outline" we received the GAI spec?

It seems extremely brief.

7.

How is large equipment moved into the Unit #1 Control Room?

There seems to be one possible wall opening on the Floor Plan and this is not shown opposite the H'atch.

(On Unit #2 we have a Hatch with Access door and the Observation Window with corridor behind it.

8.

Is panel SS-1 the Switchyard Panel and is this adequate for both units?

9.

Is the computer for Unit #1 being treated as a redundant adjunct for all but in-core monitoring and its related calculation:?

This is the case for Unit #2.

Please note that Burns and Roe, Inc. will continue our design course as presently charted v.itil we are advised otherwise.

Subject:

Control Room Design Three Mile Island Units 1 and 2 The following is a report on the results of a meeting hold on March 11, 1969 in the Interpate Building to discuss the control room design for TMI Units 1 and 2. A list of personnel attending this meeting is attached. The meeting was arranged by GPU to provide for a dissemination of information regarding the control room designs prepared by GAI and B&R, to discuss the need for conformity of design between the two units, and to determine what action should be taken to achieve the degree of conformity deemed necccsary. I feel that the meeting was very worth hile in that the information presented gave all parties a much better understanding of the baces for the designs and the degree of additional work which might be required to achieve design similarity. .__ ~ ~ ~ - ~q -Q4Tn6; Unit:lMo_ntroliro$Jdesign hasibe"en[ completed to the: point 1thefelbids-k,ontth6mhjdiffyMf?the panelschave:been solicited;and obtained.

The color codes used by GAI and BLR are identical regarding red and green but differ with the use_ of lichtiny to indicate abnormal con-ditig;m. GAI uses c:foer lights to indicate abnormaliticc3 while B&R tends to use white li hts where they provide such monitoring. 6 i B?a arrreed that they would change to um 5'+* lirhts so that the color coding will be identical for both units. 3. Met Ed expressed concern over the hookup with watt-hour meters based ~ on some reecnt prior experience they have had in this area. As a-recult, they have establiched definite requirements regardinh vatt-hour meters. It wts a5 reed that Fr. Mcy of B 2 would contact-4 Mr. Eachofer of Met Ed to determine these requirements. 1 Met Ed safety requirements require the use of terminal blocks with 6 j sliding linhs. BE agreed to use this type of terminal bicek on the I Unit 2 panels. Met Ed specified that States I"2 tc.minals be used. BLR will check to insure the compatability of these items. i f 4 j (' ,s (:,. l ^; 6/'. l d;.' 7.- ~' !R.L.WILLIIGS i nw Attachment e Cory/Attacir.ont: Mcccrs. L. H. Roddis, Jr. G. H. Ritter 'J. G.

Dear Mr. Bachofer:

} he w ur request (your memo to R.L. Williams of hil21, 1 the Control Room panels and consoles were rearrangeli[somewhat in order to provide somct similarity with the Unit El Control Room arranaement. una.s was done by shif ting panels but without redoing the layouts on tne panel races. Since then numerous small changes have somewhat altered the panel face layouts; andinow with the receipt 7 1of l drawing'sf from;B&W showing ' the -layout; on-panels'.3 :and[4, we have had. a chance.to, re--evaluate : the-- total picture.- .. Tfrom3 an f op_ era tionalis taridpoint_. ~ ~ " The enclosed rough sketch, Figure 1, shows the arrangement on panels as it now exists.

Sketches, Figures 3, 4 and 5, show the grouping of instruments on the console faces.*

Some questions immediatelv arise as to whether the present arrangement is a sa tisfactory one for the coerator. The main concern is in the dislocation of. eedwater co3trols, so that, rather than being all ~tocather, some are on the right cnd of panel 4 (in the ICS section) and come are on the i n f* o"a n f canel 5 ;' some 27 font nn,rt. Ano the r is that the arouning of , controls for startin and those for normal operation l's not ontimal.

• More detailed layouts shown in Spec. 2555-46 and B&W drawings 30755F and 3075GF 1

/ na nne rio n. in c. Novemk 9, 1970 Mr. J.L.C.Bacho fer, Jr. Page 2 - S/N 612-ME We would like to discuss the arranaement further, particularly trom the standpoint of operati on_. Specifically, we would request consideration of a change to the arrangement shown in sketch, Figure 2, which is similar to that originally planned. The proposed 3, 4, 5, 6 progression seems to lend itself to better operator-cnne*ols-nlant interface relationships,. We request your consideration of this matter. Please advise us of your comments.

Reactor Coolant Pump Monitors 1. We discussed the informal quotation made by RIS for the Reactor Coolant Pump monitors (their letter of 11/11/70). This system has been previously supplied by RIS to Duke. 2. Mr. Moy said that he needed a minimum of 8 cycles (= 133 ms) for switching in the event bus transfer becomes necessary. Thus the Monitor system response time should be adjustable i in the range 133 to 240 ms. RIS said that the proposed l equipment is adjustable in the range 100 to 500 ms 10 ms. e ,e. r-, . ~ r-

d' '/ 0 Conference Notes No. 571 Page 2 3. The proposed equipment senses a drop in power as for a parted shaft or broken impeller. (This is similar to the GAI design which was bid by GE.) The question arose as to whether we are also interested in monitoring over-power, as for a seized shaf t. This might present diffi-culties since provisions for bypass of the monitoring system would have to be designed in. No conclusion was, reached. Mr. Karish will consider. [, - _... _. _ -.-_w i B.

Computer tests arc scheduled for some time in January. .c-3 Mr. Lyc11 said that his demons trator would be available e*N # whenever wanted. Mr. Karish suggested that Messrs. igfu("s s[ i G[ p*, Lyell and Gottilla should attend these tests at Ba ley's plant in Wickliffe, Ohio. + 2.

RIS said they could supply their monitors in modules of as many as 96 points rather than the 4 presently planned. These modules would use their standard annunciator light boxes with half windows.

b. Change the desk to a simpler, smaller form approximately 3' x 8' with a two-drawer file in the center and space for two people at the ends.

(Mr. Gottilla pointed out that B&R has originally had such a desk and had been instructed by client to increase it to present size.) a

O O Conference Notes :o. 571 Page 3 This desk should be deleted from bid, (using break-down price) at the Concurrence meeting, and the new one negotiated. .The Containment Isolation paneil(no. 15).and the' c. o S EA'S' panel (no. '13) should be together, since they ~ have similar functions. Several alternative ways were discussed: i) If we interchange #12 and #13, then #13 and

1. 15 must be increased in size to suit.

11) or, alternatively, panel #8 can be moved around to make up the gap.

iii) The Rad Mon panel (#12 ) can be split in twc to lie on both sides of #14. (This means increasing #12 in size from 9' to 13'-6".) . ~. - -iv) _ Theipanels-#15 and #13,can 'b:e lef t ' separated; ; Burns arid ; Roe" prefers: alternate n no div; 2butipromi' sed " toistudy the~others.

Mr. Moy said that no. 18 could not. B&R agreed that no. 10 will be rearranged, as mentioned above, to accommodate more temp. points but that it would not be compacted if we wanted to keep the " spare" ~ " - " recorder. Mr. Karish said that we did want to keep it. 2. $r.

Mr. Karish pointed out that the Mercury Addendum al bid listed Transmation as the supplier for square root conveyors. B&R said tha t this was in error and would be changed to Foxboro. 2. Mr. Karish asked that we get prices on L&N recorders in place of the specified Esterline-Angus. We pointed out that one of our reasons for E-A was that we had a mix of RTD's and thermocouples and that E-A could supply j such a recorder. He will consider further and re-discus'.s 3. Mr. Karish asked that B&R check the high Bailey RY indicator prices. (We did and verified then, but feel now that if Mercury's supplier can furnish 1% instru-monts, they are acceptable.) E.
