f test results obtained with a ICO-red scaled systems effects test facility, as well as with preliminary calculations obtained with the TRAC-P02 code. The USNRC-supplied instrumentation (spool pieces, LLD's, etc.) has proven to be essential in analysis of the data in order to provide unambiguous mass balance information.
Final a JAERI (greement was reached in May 1980 between NRC,
~
and its contractor, IHI) and the NRC contractors
(.the DOE laboratories ORNL, INEL and LASL) on the selection, location and delivery of all the USNRC-provided instrumen-tation for the SCTF Core I.
The in-core gufde tube impedance probes and liquid level detectors (LLD), the
. cold leg and vent pipe spool pieces and,the upper plenum fluid distribution grid (FDG) for this facility were delivered to Japan in May/ June 1980. Fabrication is in progress on the hot leg spool pieces, downcomer FDG, video-optical probe and remaining NRC instruments to be delfvered to Japan in the period between. July 1980 and January 1981. The design of instrumentation for CCTF
- Core II has. been started..., --
The 340-red PKL systems effects test facility in Gennany was redirected by the BMFT last sumer on the basis of recomendations from the 30 Program to investigate events leading to core uncovery in PWR's during small brsaks with natural circulation. The NRC had the spool pieces and tur5ines, which we supplied last year for PXL Core II, modified in order to measure the low flows anticipated in the natural circulation tests in the extended test program with PKL Core I.
In addition, NRC loaned the FRG a pulse neutron activation (FNA) device built by Sandia (5ased on an Argonne National Laboratory design) for measuring more accurately the extremely low loop velocities.
The natural circulation small break and core uncovery tests in PKL Core I were comoleted in June 1980 and the facility shut down in preparation for installing, Core II later titis year. The preliminary quick -look test results have 5een supplied to the NRC. Ce ailed test reports are to de icsued later.
The PKL steady-state '.atural circulation tests at 0.75t Cequivalent PWR) full power demonstrated that the heater bundle could be adequately cooled by single and two-phase primary natural circulation flow over a range of primary i
steam voids up to 30%. At high steam void fraction in the primary system, the top of the core bundle was uncovered Eut still the bundle was adequately cooled by reflux L

steam / water heat transfer to the steam generator'. Transient tests, at 1.37, (equivalent PWR) full power with small and medium-size breaks and ECC injection and secondary heat removal, exhibited similar cooling of the core with single and two-phase natural circulation and reflux boiling occurring with increasing break size.
In all the tests, the heater bundle was adequacaly cooled by eitner natural circulation or reflux bofling action.
Tne German UPTF system design was reviewed and accepted by a FRG review group in a meeting in Gemany during May 1980. Because an effort is being made by the BMFT to obtain a fixed-price contract for the facility constructien, the award of UPTF fabrication contracts will be delayed into early CY 1981 and hence delay UPTF construction comolation.
Schedule:
The current 3D test facility schedules are given in Figure 1. There is no significant change in the JAERI CCTF and SCTF schedules. Mcwever, the start of testing in the Genan UPTF facility will now be delayed by 2 years to January 1984. This will have an impact on the NRC 3D Program funding needs as discussed below.
The delivery of 30 instrumentation is on schedule matching the JAERI facility requirements. The milestones for this are shown in Figure 2.
The only effort currently benind schedule is that associated with the TRAC CCTF post-test analysis at LASL. LASL has experienced difficulty in getting accectable predictions with TRAC-PI A.
LASL is working on an improved version of TRAC PD-2, which is expected to resolve this problem.
Costs:
The 30 budget projection and expenditures for this. fiscal.
year up to and thru May 1980 are shown in Figure 3.
The expenditures of all the centractors are within baseline budget agreements. A cost underrun is anticipated in FY 30 5ecause of 01 material purchase comitments for which funds are yet to de costed, and {.2), the deferral of the start of UPTF fnstrumentation design and fabrication hecause of the slip in the German facility schedule.
The Commissioners 4
Imoact on 3D Cost Estimate From UPTF Schedule Sliocace The German UPTF schedule was initially delayed last fall while FRG Government approval for the increased costs of changing the UPTF facility to full scale was sought.
Since FRG Ministerial approval of the increased German.30 budget in January 1980, tHe Germsn progrid is incurring additional delays in selecting a construction contractor.
As a result, tasting in UPTF is not expected to start untfl January 1984, approximately 2 years later than erfgtnally scheduled.
The impacts on NRC's 3D estimated costs due to this delay will be:
Ol To defer $1.6 million of the baseline estimated costs in FY 30 to later years, and (2l To increase the 3D estimated overall requirements by about $3.4 million in and after FY 33.
A prelfmfnary 3D cost estimate is shown in Figure 4.
A more accurate estimate will be submitted for the Commission's approval after the exact German UPTF schedule is estab-lished in the coming July 30 Coordination Meeting at Muntch.
