SUBJECT:

MEITIOPCLITAN EDISCN'S PROPOSED ACTICN ERIOR T3 'IMI-l STAR'IUP l

I was present at the NRR Staff meeting en June 11, 1979, in which represent-atives from GPU and Met. Ed. briefed the Staff on proposed actions they would take as a result of the 'IMI-2 accident.

It was decided that Met. Ed. would s

in the near future sutrait a draft comitment letter on all the items covered in the meeting. Met. Ed.'s desired startup date is August 15, but H. Denton l

indicated that there may be difficulty for his staff to complete review by then.

The general feeling of the NRR Staff was that Met. Ed may be attempting to do too much in too short a time. Highlights of the proposed actions are sumarized below:

l OPERATOR RE'rRAINING PRCGRAM This training proran will provide operators with 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> of simulator training specifically geared to the 'IMI-2 transient,108 hours0.00125 days <br />0.03 hours <br />1.785714e-4 weeks <br />4.1094e-5 months <br /> of classroom instruction on subjects such as heat transfer end fluid dynamics, manometer effects, 'IMI-2 transient, instrument response to transients, ard small break l

LOCA operator guidance.

Mr. H. Denton painted out that passing grades on oprator exaninations should be 90% rather than 70%. 'Ihe ability of an i

operator who got only 70% is questionable.

i I

Met. Ed. plans to complete all operator retrainirq prior to restart of Unit 1.

PROCEDURE CHA'CES I

About 80 - 100 emergency procedures are being written by the engineering 4

and operational staff. 'Ihe new procedures will reflect NRC bulletin guid-ance, specifically, on adequate subcooling, continued RC pump operation, g

and non-defeat of ESF equipment. A new procedure on natural circulation will be added, and intelligence, based cn multiple plant parameters will be N

emphasized. Administratively, each shift will be strergthened by havirg a H

degreed engineer in each, ard by ensuring availability of standby personnel.

g New phone systems have been installed for NRC notification. Maintenance /

g surveillance procedures are beirg revied to insure no more than cne safety g

train is defeated during maintenance or testing operations.

and systems.

l EMERGENCY PIANNIT Met. Ed. plans to expand its program to four phases (see Attachment 2).

J. Sears of NRR pointed out that con.pliance with Regulatory Guide 1.101 l

~

would haea included all of these @ases.

As mentioned before, some cocununications equipment has been upgraded.

H. Denton said that in the first few days of the accident, NRC was not able This lack of understanding to cocrnunicate with Met. Ed.'s upper management.

resulted in considerable confusion.

SAFETY ANALYSIS i

Met. Ed. has reviewed the TMI-2 analyses and determined that the loss-of-feedwater, small break LJCA, and loss-of-offsite-power accidents should be redone, with natural circulation being a major concern.
