Mr. D. G. Eisenhut April 19, 1982 ATTACFFENT I.A.3.1 Simulator examinations are included in our licensing examinations.
This item was connleted on schedule.
II.B.2 Plant shielding modifications to provide access to vital areas under accident conditions have been completed. This item was completed on schedule.
II.B.3 Post-accident sampling system upgrades have been installed and preoperational testing is well underway. Several problems remain, some of which require vendor parts and vendor technical assistance. Timely delivery of parts and vendor information vill 4
allow the system to be operational by June 1, 1982.
II.B.h Training for mitigating core damage was completed and reported in our letter of December 31, 1981.
II.E.1.2 Hardware to implement this requirement has been installed as reported in our letter of August 11, 1981.
II.E.h.2 Our containment pressure setpoint is set as lov as is consistent with normal operations. Please see our letter from Mr. L. B.
Russell to Mr. D. H. Jaffe dated January 21, 1982 for additional specifics on this item. Our purge and vent valves shut on a radiation signal as reported in our letter of August 11, 1981.
II.F.l(l)
Noble Gas Effluent Monitor - Installation has been completed for some time, and the preoperational test is complete on Unit 2.
We have encountered numerous equipment problems during testing and have been working continuously to close open items, all of which require vendor resolution. Assuming timely action by the vendor, we expect to have an operational system by July 1, 1982.
Compensatory measures ac implemented for short term requirements of January 1,1980 vill be continued tmtil the system is fully operational.
(2)
Noble Gas Steam Effluent Monitor - We have had numerous vendor problems and have yet to receive the equipment. The earliest shipment date is now mid-May, and this date assumes prompt resolution of factory test problems. Installation of the first (Unit 1) monitor is scheduled to take a month after delivery.
The Unit 2 monitor vill then be installed during the fall refueling outage, necessary because of high temperatures in the equipment room which prevent installe. tion during plant operation.
Thus, both systems should be completed by December 31, 1982.
Compensatory measures consist of a system using dedicated portable instruments, placed in operation to meet short term requirements on January 1, 1980.
(3)
Our containment radiation monitor is installed. Please see our letter of April 13, 1982 for additional information on this item.
(h)
Our containment pressure indication is monitored as described in our letter of December 15, 1980.
(5)
Previously complete, found deficient after an initial period of successful operation.
(See our letter to R. A. Clark dated January 19,1982). We expect to complete installation of instruments of improved design during the refueling outage now underway for Unit 1 and beginning in October 1982 for Unit 2.
(6)
The first hydrogen monitor unit is installed and testing is underway. Vendor assistance is required to resolve problems with analyzer repeatability. Because of the indeterminate nature of the problem, resolution may not occur until May 30, 1982. Installation of the second unit vill begin upon completion of the first, and should neet the criteria of NUREG-0737 by August 1,1982, assuming minimal problems during installation and testing. Should completion extend past August 1,1982 due to unforeseen problems, it will be necessary for us to submit a request for amendment to our Technical Specifications to allow continued operation. Reasons for the delay and compensatory measures to be taken until the second unit is operational were discussed in some detail in our letter to R. A. Clark of October 26, 1981.
