gueri i t .1 1. In the " Report on Containmen t Building Ring Girder Conctruction and Repair' and addeadums thereto, it wa s n o t a.1 chat dirt and debris '.cere founil in the joints in the south 180' . Pl ea s e state the condition of the construction jo.ints in the remainder of the centainment building.

Onm.t inn 2. Ilow was the condition of the joints in the remaincier of the containment indicated in Question 1 determined?

Por r it n 3. Name.the entity or entities responsibic for inspection of the construction and construction techniques.

Please list addresses, also. .

Question 4. Please lis t the following in formation wi t h respec t to all persons performing an inspection func tion

a. The total number of people

b. The name,addre.ss and employer of nuch porson

c. The immediate nupervir.or inul t i t le of each pers.on

d. The particular inspec tion function of each person.

Ouontion 5. Describe the func tion of the inspectors mentioned in Quest. ion 4 with respect to their ability to stop construction.

Qucation 6. Please state all particulars regarding an inspectors authority to stop construction.

Ouention 7. State in detail the discussion and by whom the decision was made with regard to the continua tion of construc tion e f ter the " honeycomb" concrete defect was discovered in the North 1.80 of the ring girder.

Questien 8. What will be the effect of any repairs made to the ring girde.-?

Questi.on 9. State in detail the effect of the repairs upon the n t cen; th and in te;' ri r-j of the con tni.nmen t Structure.

The Metropolitan Edison Pever Conpany orrani:ation vill handle the task of quality control to ensure t. tat tae plant to constructed in accorcance with the requircaents of the design. M.P.R. Associates . Inc., vill act as a consultant and is respcasibla fer developin. quality control procedures.

'Jser testing of the natorials of constructica is indicated. The construction cuality control pregran provides an adequate separation of ecastructicn and inspection functicna, adequato authcrity for the quality control per:cnnel to perforn properly, anc &si;n group revicv of the constructicn pronresa.

Testing and_ Inservice Surveillan_ce, An extensive program of acceptance testing for both structural and leaktightness has been indicated. The pregren to establish structural acceptance vill include instrumentatien around the lar-e openiac,, at t i c.

discontinititios, on selected tendons and en the liner to provide assurance that ancmalous structural behavior vill be detected. Likevinc, extensive preoperational integrated leakaa,e tests cre nroposed to establish the structure's leakage characteristics.

Detailed inservice surveillance progr:ns hava ?.ot been established.

dovever, the desi 7n haa 'ocen chan-ed to allev tenden re jccLini, rcroval and replacenant. Tacrefore, it vill have adequate capability for a suitable program and review of these areas can be left for the operating stago.

With regard to selection of structural test prassurs, the desi;ncr has elected to use the 113 percent of the Jenien basis accident pressure.

Inasmuch as increased leaka;c has typically been associated vi:a the opening of leakaze paths at hiqh tensile streases, the overall (integrated) leak rate pert'oraanee of the vessel undar test pressure loadings at decinn basis accident pressure in expected to be conservative with re ard to its related perfornance under design basis accident conditions.

It is concluded that the dosian, as presently rremoced. and tne construction, as incicated, vill result in a structura adecuate for 1:2 intended purpcaa.
