A neeting was held with representatives of Jersey Central ?cwer a *ich:

Cc pany (JCFL) en February 14, 1969 in Be:hesda.

Aa. attendance.is:

is attached.

2.e purpose of the meeting was to discuss the applicant's (1) design criteria for aircraft missile and fire protection, (2) surveillance program f or grouted tendens, and (3) quality assurance and control progran f or the Three Mile 'sland '.'ni: :;o. 2 (~'il 4 2 ). ::

was our understanding that the revised ?SAR (A=endmen: 6) wculd be sub=itted on February 17, 1969; however, JCPL infor:ed us that Amendment 6 would be delayed several weeks due to unacceptable printing and imprcper designatica of changes in the ?SAR. Two ccpics of the

?SAR were left uncfficially.

requirements of the TMI #1 for aircraf: missile and fire protection.

All buildings of O!I 12 which contain equip =ent essential to the safety cf the plant er contain radicactive raterials will be designed to withstand a 200,000-pound missile with a 19-fco: diameter and an impact velocity of 200 knots /hr.

2:e Franklin Ins titute was used by Burns i Ree to deter =ine the

~

dynamic respense of the ccatainment shell to an aircraft strike.

All other buildings will be designed using a static analysis. JC?L will provide infor ally some sketches of wall structures shcwing thickness and design of certain buildings which Dr. 'iec. ark requested to assist his review of the facility. Preliminary analysis indicate wall thickness of approximately 3 feet will be required.

S.e criteria

..:n will be used in design for aircraf: protection are:

1.

no missile pene:ra:icn er but..ing collapse 2.

safe shutdev. capability (both plants considerint an impac: en one cercurrent with shutdcw-of the other) 3.

iccrs, vents and cpenings must be desi2ned to orevent

ngress of fire er smoke.

cn:rol roc must be habitab'e.

JCPL has indicated that it had no surveillance progran for the gromted tendens.

It indicated that if the tendons were suspected :c have deteri: rated during the 40-year plant life, a pressure test at 115*.

design pressure would be perforced.

The applicant was informed that we had reasonable assurance that 2ced grouting could be accc plished, however, we felt it should develco scte type of surveillance progra to detect deterioration of :ne tendons which could affect the containment capcbility.

JCPL indica:ed it would centinue to analyze the problem of tenden surveillance and would mee: with us in several weeks to discuss the

JCPL's quality assurance consultan:, MPR, reviewed the quality assurance progran for IMI #2.

A generic type specification was described which will be incorporated into the TMI 42 PSAR.

This generic specification covers iters 5 thrcugh 22 of the recently r4ublished Nuclear Power Plan:

Quality Assurance Criteria, dated January 1,1969, indicating the JCPL recuiremen:s which cust be contractually =et by equipmen canuf acturin centractors, site construction centrac:crs and their sub-con:ractors.

Rcger 5. Scyd Inse:vice Insoec:1cn %-15 JC?L has indicated tha: the OMI v2 design has been reviewed to insure that accessibility and race exists :c persi: the inservice inspection described in the N-43 Ccde.

It stated that a study had been made to determine what ceco.lete ceco.liance to N-43 wculd rean using-. resent-c day inspection techniques and equipment. The conclusian was the dose received by inspection personnel in carrying out the inservice inspec-tien was unacceptable.

General Public L'tilities is centinuing to f ollow the develccment of new re cte inspection equip =ent and techniques.

It is preparing an in-s er/ic e inspectica progra based upon usage of present-day insoection equipment and :echniques.

We indicated tha: addi:1cnal infor:ation on the inservice inspection may be required after Arend en: 6 has been recet.ed.

Acticn Items 1.

JC?L will subri: informally preli=inary building details for aircraft protection. These will be forwarded to Dr. Newmark.

2.

Subri: letter to applicant regarding requirement for tenden surteillance.

3.

We are reviewing informal infor:ation concerning the radiclytic hydrogen generated folicwing the LCCA to deter =ine need for further infor:ation.
