March 3,J 969 2.
Hurricane Protection The : licensee's engineering ecatractcr, GAI, presented a mcdified analysis "of maxicram probable hurricane effects based en criteria described lu ESSA. reports EUR-7-97 and EUR-7-97A. The original-
< analysis in the PSAR predicted a sto=. tide level of 21.h feet and a'vave height.cf 9 feet. The mcdified analysis predicts 2h.6 and 11.k feet, respectively.
In order to maintain the same grade elevation around critical structures as previcusly used, namely 30 5 feet atove MLW, a modified wave treak vas designed. The new wave-break cuts the wave in a stair-step manner before it can reach plant grade.
Model studies are in progress; a film is being made.
Lov vater cal:ulatiens were redene, fer two different stc=s.
It was concluded that sufficient margin was available in the inlet canal for running the chutdcwn eccling pumps.
We said that we veuld need the results filed.
3
. Seismi and 31cudcvn'Fcrees 3&W sail that their analysis was ecmplete.
A t:pical report is to te publiched in the second quaner cf 1969 4.
Control' Red Drives FFC.is changing te the roller nut system, as nre most other 3&W custccerc.
374 vill be publiching a tcpi:sl report in the se:cnd quarter of ICc9 We said we vculd need scme notificatien of intent
+
by FPC.
5 Separation cf Centrol and Sefety We notified FPC that we had hela a =eeting with 3&W cn this subject
.in relation to the S&W product line. -We also notified FPC that the
' subject of syste=atic, nenrandca failures was being cencidered.
- (Such failures were,not included in the Crystal River ACRS letter. )
B&W vas. vague in specifying any performance dates on their study of systematic -; failures.
We told FPC that no decisien had been made at this : time regarding -the application of the results of the forth -
+
coming study toLtheirl plant. We also sali that we mignt have tc request the study be filed on the record for the Crystal River Station.

Fart-Length Reds According to M W, the modal analysis shevs that axial instabilities (xencn oscillation) may occur. Hence part-length rods vill be used.
Sc=e design details are presented in Oycter Creek 2, Supplement 3, Q estion 7 1.
The. part-length design vill te used in Occces units also. We said that we anticipated a comprehensive review on the
' Oconee POL,.and had'no additicnal questions to FFC at this time.
7
. Reacter Building Fan Ccclers 4
The design fur these coolers vill be essentially the same as for Met-Ed. The :ccler =cters will be through testing in March 1969
. The results will be made available en the Met-Ed project.

4= ""' ' ' e d cr no raview is indiated en FFC, assuming satisfact cn Me -Ei.
We vill require sc=e identification frem FFC that the design and installaticn'is such that the Met-Ed results apply.
6.
Failed Fuel 7'ae retecter MW is nearing the end of the first phase, a scopin6 study, on this subject.- They expect to have a repcrt available in mid 1959 We noted that we had asked for this information to be filei en the Met-Ed project, as no tcpical report was envisicted by MW.
9.'
Fre ssure %.:el Thermal Shock
' M'.. expect: to submit a tcpical report en this subject in May 1969
[-
We reminded FFC that cur safety evaluation had charged the applicant with the duty cf exploring possible changes to the facility to g
eliminate the need for censidering potential vessel failure due to thermal. shock. However, it was determined that nothing had been dcne to date.
We should review the topical repert before deciding inat cur next etep should be.
10.
Cus11ty Assurance We had made available to FFC a January 1969 draft of quality Assurance crite ria. - FFC'in turn delivered a presentation on their pecgram.
j In-brief their program =ay be put in matrix form. The rov entries l~
. consist cf three levels of -quality effort labeled Guality Contrel,
.Cuality Assurance, and Cuality Surveillance. The column entries were Design, Frecurement, Manufacture er Shep Fabrication, Construc-tion, and Testing. At each row-column intersection there were plans for acccmplianing the desired functien.

' M-March 3, 1969 tTheir.. plan.and presentatien was not directly respcnsive to cur draft criteria, and-their terminoicgy is not entirely eonsistent
~
tvith curs. 'Nevertheless it appears that their plan could ade-
"quately serve their requirements.
We asked FFC to sh v,' for example, how the %.3 liner would foll:v through the cuality chain, frem design to testing. They did so, One 'possible weak point is in their (FFC )
in.a reascr s' manner.
Surveillenc-nctien. FFC utill:es a QA engineer ensite for this function.
1s remains to be. seen whether he can perfern the myriad
'of duties that the assignment appears to require.
Cc pliance shculd 'ce aware of our ccncern as their field inspector, J. C. 3ryant, was in attendance.
E* '
We chcull esk fcr the FFC plan en the rescri.

Lynamic Analysis of Pining We noted that cur consultant, Dr. '!erar2, had reccemended (and the appl 10 ant, agreed' that a f;r al dynacic analysis of Class I ctruc-
.tures, equipment, and piping be perfersec..
We asked what progress had been =sie.. Gilbert Associates (by Ecb Ecttenstein) said that they had made substs.ntial prcgress in this matter,4and could make
+-
. available ~ su:h infcrmutien as acerad tc be apprcpriate.
We told FFC thet _ve vrld notify shm se tc the depth cf informaticn desired. - -

It aptears that

13._- 1 Ccntainment Design Change LFFC notified us ~(verbally) cf their intenticn to change frcm 90-wire

to 163-vire prestress tendon. The change vill.'ce s_imilar to the Lpresented Met-Ed design. Differences will include the 33RV. vendor, vire diameter,. type of wire, vire vendor, and anchor plate size.
We -teli FPC.that this' change veuld require. formal documentatien.
