Dear Mr.Case:

8~.",+p~17 Re: Nine Mile Point Unit 2 Docket No.50-410 Enclosed is the additional information that Mr.Varga of your staff requested in a letter dated April 6, 1978 regarding the Niagara Mohawk Power Corporation request for an extension of the latest completion date for Construction Permit No.CPPR-112.This information quantifies the extent of the delay associated with each of the three causes cited.It also identifies on a time scale, the point at which the delay was incurred and the extent it alone affected the overall schedule for completion of the plant.The delays show good cause for extending the latest date of Construction Permit No.CPPR-112 to December 31, 1984.Very truly yours, NIAGARA MOHAWK POWER CORPORATION Ger ld.Rhode, Vice President System Projec Management NLR/s zd Enclosure 781210)ag Soo<s(a+I/g

SUBJECT:

TRIP TO LIVERMORE, STANFORD RESEARCH INSTITUTE AND GENERAL ELECTRIC TO DISCUSS MARK II POOL DYNAMIC LOADS~kkdd The purpose of this trip was to discuss several analytical and experimental programs related'o Mark II pool dynamic loads.A copy of the attendees, agenda and slides distributed at the meeting are attached.In the morning of the first day (Wednesday) we met with Livermore personnel to discuss the Livermore/DOR program to study fluid structure interactions (FSI)in the Mark-I Monticello Safety Relief Valve (SRV)tests.a Wednesday afternoon we met with personnel at Stanford Research Institute to discuss their 1/13 scale Mark II pool swell tests.Thursday we met with representatives of the Mark II owner's group and General Electric to discuss the status of several tasks in their Mark II pool dynamic load program.A summary of-the topics discussed in the meetings is provided below.~Sumar Livermore Meetin Ed McCauley of Livermore summarized the results of the FY 77 Livermore FSI program.Their study of SRV-FSI effects showed a trend of decreasing loads with increasing wall flexibility.

The major limitations of their study included the plane section modeling of the containment and the modeling of the source.These assumptions result in an over-estimate of the dependence of SRV loads on wall flexibility.

Future studies by Livermore are aimed at evaluating the importance of these parameters.

h APR 35]g7g Standford Research Institute Meetin The purpose of this meeting was to discuss the preliminary results of the'Mark II 1/13 scale single vent tests.These SRI tests consisted of air charging tests..Shakedown tests were conducted to determine the affect of water vapor in scale air tests on pool swell phenomenon.

The preliminary results for the SRI tests showed differences from similar tests conducted at MIT.The purpose of the meeting was to identify reasons for the differences.

Additional SRI testing was.discussed to resolve differences in results.Hhi'le at the SRI facility we toured the pool dynamic test stands.Me noted that SRI is conducting EPRI funded tests to investigate steam chugging phenomena.

Tests are being conducted at three different scales including single and multivent tests.This test program is a study of the fundamental phenomena of chugging.This program is not a par t of the Mark II owner group supporting program.Mark II Owner's Grou Meetin The topics discussed in this meeting are listed in the attached meeting agenda.A summary of discussion follows: 1.Monticello SRV-Mark II Fluid Structure Interaction Studies Or.H.Tang of General Electric discussed the results of studies at GE to determine the effect of containment wall flexibility on the measured SRV loads in the Monticello tests.GE performed calculations similar to those performed by Livermore.

Their plane strain calculations utilized similar assumptions of containment rigidity and load source to those performed by Livermore.

Under these conditions they observed the same trend of reducing load with increasing wall flexibility as observed in the Livermore studies.However, the GE studies were extended to include axisymmetric calculations, 3D modeling of a torus segment and a multiple pulse source.Results of these studies show that wall flexibility amplifies the loads.This conclusion contradicts the Livermore 2D study.In addition they conducted analytical-experimental comparisons using their model and the Monticello data.The use of the more realistic assumptions in the analytical model substantiated the Mark II owner's claim that the Monticello benchmark is valid.The Monticello FSI study is now considered complete by the Mark II owner's group.Documentation will be provided to the NRC by the end of May 1978, In our March meeting with the Mark II owner's group we discussed the desirability of formulating a conservative chugging impulse load to resolve 4 T FSI questions.

Dr.Healzer of General Electric discussed their plan for this task.They should complete this study by early June 1978.A status report will be provided at the next Mark II owner's meeting.This meeting is tentatively scheduled for mid May 1978, In addition we requested that Dr.Healzer provide us, within the next few'eeks, an outline of the objective of this task.3.SRV Pool Tem erature Limits T.Su of NRC provided an NRC status report on the issue of SRV pool temperature limits.He stated that based on our current review of the small scale tests there is inadequate supporting data to justify the current pool temperature limits for rams-head relief valve devices.As a result of our review we are preparing an NRC position requiring the use of quencher type devices in Mark II plants since these devices have higher pool temperature limits.4.DFFR Lead Plant SRV Loads T.Su of NRC provided a status report on the NRC review of the Mark II ramshead model.He highlighted several deficiencies in the current model.We also discussed the use of the ramshead model for those lead plants which have committed to a switch from a ramshead to a quencher device.H.Brinkman representing the Mark II owner's group stated that their plans are to use the current ramshead model to predict SRV loads for plants with quencher devices.Test programs are being developed to show that the use of these ramshead loads for quencher devices is a conservative approach.Current plans call for completion of the confirmatory tests prior to operation of the first Mark II plant.5, PSTF Im act Loads G.Maise of BNL outlined the results of the NRC evaluation of Mark II Pool Dynamic-impact loads.This study concluded that the current DFFR impact load specification is inadequate in that

4 APR 2g]97B the impulse load specification does not include a conservative pulse duration.In addition no consideration has been given to the affect of target geometry on the impact load.The Mark II owner's stated that they had not had sufficient time to review the basis for our conclusions nor the impact of this potential load modification on equipment in specific Mark II plants.Their preliminary review of the BNL study has not uncovered any deficiences in the BNL study.However, conservatisms in the current impact load specification could be balanced against these recently identified non conservatisms.

At the next Mark II owner's meeting in mid-May the Mark II owners will provide us their evaluation of the BNL study and a review of the impact of this load modification on specific Mark II plants.g.(<,6 I.Peltier, Project Manager Light Hater Reactors Branch No.1 Division of Project Management
