SUMMARY

This testimony responds to the_ Appeal Board's question regarding the status of installation of the hot leg high point vents at TMI-1. All basic preparatory work for the vent installation has been concluded and the majority of the required materials for completing this modification have been received on site. The remaining work items, consisting mainly of electrical and piping installation, are now underway. The earliest date for completion of this modification is currently 1

estimated to be May 21, 1983.

y INTRODUCTION 2

This testimony, by Francis F. Manganaro, Vice President 3

and Director of the Maintenance and Construction Division of 4

the GPU Nuclear Corporation, is addressed to Issue No. 3 of the 5

Appeal Board's Memorandum and Order of December 29, 1982 6

(ALAB-708), which asks:

7

3. The current status of the hot leg vent 8 installation (from the licensee).

9 BY WITNESS MANGANARO:

10 The modification at TMI-l which will provide venting 11 capability for the two steam generator hot legs is being 12 accomplished under my direction. This is part of a modifica-13 tion which will provide reactor coolant system remote, high 14 point venting capability not only for the steam generator hot 15 legs but also for the pressurizer and reactor vessel head.

16 Installation of a high point vent on the pressurizer has been 17 complsted. A vent on the reactor vessel head is scheduled to 18 be completed during the next refueling cutage. Installation of 19 the hot leg vents is now underway.

- 20 Preparations for the installation of hot leg vents have 21 been ongoing for some time. Construerability reviews in both 22 piping and electrical areas have been completed and the results 23 provided to engineering. Although some of the engineering 24 which has been provided to date is preliminary, sufficient 25 progress has been made to accomplich virtually all the planning 26 for the work and the development of a schedule to complete the work. Installation of required switches, indicating lights and

y internal wiring in the PC Panel in the Control Room was 2

mpleted in 1982 as part of the pressurizer vent modification.

Sandblasting and painting of related electrical conduit 3

commenced the third week in January. Most of the Job Orders to 4

5 perform the work were issued by mid-February. Orders for 6

nstruction of scaffolding and painting of raw material have 7

been released and that work is ongoing. All material required to perform the rest of the work has been identified and most of 8

g the material is on hand at the present time.

10 The total remaining work scope has been divided into three 11 maj r activities:

12 A. Electrical installation outside Reactor Building; 13 B. Electrical installation inside Reactor g Building; and C. Piping installation inside Reactor 15 Building.

16 All three activities were started in mid-February. The present 17 schedule indicates an earliest system operable date of May 21, 18 1983, and the critical path is through the electrical installa-19 tion inside the Reactor Building.

20 Manpower application has been maximized with due regard to 21 efficiency and productivity. All activities which can be 22 worked in parallel with one another have been scheduled in that 23 manner. The schedule is based upon a six-day, ten-hour-per-day 24 work week. Manpower required to accomplish the work will vary.

25 It was approximately eighteen (18) men per day at the beginning 26 and is expected to peak to approximately thirty (30) during the March-April period and taper down to approximately eight (8) as 1

the work nears completion. Support manpower during the first and last months of the job, mostly involved in the installation 2

and removal of scaffolding, will average approximately fifteen 3

(15) men per day.

4 The present schedule necessarily is adjusted as engi-5 neering is mpleted, materials receipt is finalized and as 6

w rk progresses. It is not expected that the final schedule, 7

8 however, will result in any significant change in the presently projected May 21, 1983 system operable date.
