Hot Functional Testing (HFT) Procram a.
TP 600/28 Controlling Procedure for HFT The inspector discussed the purpose and scope of this procedure with cognizant GPU Startup personnel. Additionally, on December 28, 1973 the inspector reviewed the official field copy of this i
procedure and, while in the Control Room, observed plant activi-ties in progress being controlled by this procedure.
The follow-
,
ing observations were made:
(1) This procedure establishes a sequential logic schedule for
'
test and event performance beginning with initial steam bubble formation in the pressurizer and ending with fuel loaded in the reactor vessel.. Additionally, various data
>
sets throughout HFT that have not been included in indivi-dual HFT procedures are recorded in this procedure. The
,
HFT program is divided into eight (3) phases as follows :
(a) Phase I
- Pressurizer Bubble Formation R
(b) Phase II
- First RCS (Reactor Coolant System) Heatup fV to 5320F, 2155 psig j
(c) Phase III - 5320F, 2155 psig Testing (d) Phase IV
- First RCS Cooldown
'(e) Phase V
- Second RCS Heatup to 5320F, 2155 psig (f) Phase VI
- 5320F, 2155 psig Testing (g) Phase VII - Second RCS Cooldown (h) Phase VIII - Post Cooldown Testing
Following completion of Phase IV, a maintenance outage is scheduled to correct identified problems.
Additionally, any tests not completed during Phases I-IV will be rescheduled for performance during the remaining phases.
(2) A partial issue of this procedure was approved by the TWG on December 14, 1973, and this action permitted the commencement of Phase I on December 19, 1973.
(3) A complete issue of this procedure less the sequential logic schedule for Phases V-VIII was approved by tSe TWG on December 22, 1973.
The sequential logic schedule for r>hases V-VIII will be issued by a TCN to TP 600/28 on a later date.

Prerequisite List for HFT The Test Manual and Test Instruction No. 10 establish requirements for the prerequisite list, which contains all items that must bethe satisfactorily completed or in a state of readiness to support start of major events.
The list is also required to be periodically The updated and reviewed prior to commencing the associated event.
official field copy of the prerequisite list for HFT was approved
by the TWG on November 21, 1973 and was periodically reviewed and updated by GPU Startup and Met Ed personnel prior to its final approval by the TWG on December 26, 1973.
This prerequisite list was in conformance with Enclosure 1 of Test Instruction No. 10.
During the licensee's periodic reviews, deficiencies and exceptions (~
were identified, and the resolution and evaluation of each item was
-
documented as required by Test Instruction No. 10.
,
'/
Documentation contained is. the official field copy of this list was
'
discussed with cognizant GVU Startup personnel.
Additionally, the systems employed by GPU Startup.in order to complete the required signofts in this list were reviewed with these personnel. No deficiencies were identified.
c.
Test Manning Assignment Document _

Pipe Haneers and Restraints The licensee's program relative to pipe hangers and restraints was reviewed by the inspector. This review included discussions with cognizant licensee representatives and examination of pro-cedures and documents to implement the program. The folicwing observations were made:
.
(1) Preoperational Test Procedure TP 600/14 Pipe and Component Hanger Hot Deflection and Inspection Test and TP 600/29 Re-actor Coolant System Thermal Expansion Functional Test and Construction Procedure MCP-15 Adjustment of Hangers establish
,
the requirements for the program.
Additionally, the perfor-mance of these procedures is controlled by TP 600/28 Controll-ing Procedure for HFT.
(2) The program provides for the following:
I (a) Verification of correct installation, i.e., location, type and cold setting prior to starting HFT (RCS temperature i
>2000F) by UE&C Construction and Quality Control.
'
c3 l
\\:
(b) Verification of correct hot setting during HFT by UE&C Quality Control under the direction of a GAI Engineer.
Tc) Observation of piping movement in the Reactor Building during HFT by UE&C Construction, GPU Startup and GAI
,
to insure adequate clearance between piping and any
-
!
portion of a building, other objects, structural members, t
and other pipes.
(d) Verification, check and measurement, where necessary, of the travel indication of large diameter pipe lines within their Loss of Coolant Accident (LOCA) Restraints and parts of the LOCA restraint system of the Reactor Coolant Pumps (RCP) prior to and during HFT by GPU Startup and GAI.
(e) Verification of predicted travel of RCP motor constant
. load supports and steam generator auxiliary feedwater header supports during HFT by GPU Startup and GAI.
(3) GAI provided a nucleus of piping engineers to carry out the necessary GAI designed het system checks in support of a commitment to GPU and the AEC.
Additionally, these personnel will provide technical support during the power escalation testing program.

TP 600/20 Loss of Electrical Power Test (W thout E.S.)
-
l TP 600/20 was performed during Phase I of HFT, and Part B (simu-lated failure of Auxiliary Transformer IB) of this test was witnessed by the inspector on December 21, 1973. Additionally,
'
the official field copy of TP 600/20 was reviewed on December 21, 1973. The following deficiencies were identified and discussed
,
with cognizant licensee representatives:
,
.
(1) The referenced drawings in Paragraph 2.1 of TP 600/20 were
not initialed and/or excepted by the STE or his designate f
prior to starting the test, thus documenting the review and evaluation of drawing changes issued after the procedure
.
l vas approved. This action is required by Paragraph 3.3.1.7 of Test Instruction No. 9.
.
(2) For Parts A (simulated failure of Auxiliary Transformer lA)
and 3 (simulated failure of Auxiliary Transformer 1B) of
'
this test, test exception changes, verification of Pre-requisite System Conditions, and data recording and signoff
,
i were not always properly documented, as required by Para-graphs 3.3.2,6, 3.3.1.1, and 3.3.2.4 of Test Instruction No. 9.
These deficiencies were observed in the following procedural steps and data sheets, as appropriate:
Steps 8.2.1.4, 8.2.6.1.b. (a) and (b), 8.3.1.4, 8.3.5.1, 8.3.6.1.b.
(a) and (b), and 8.3.6.2.b. (a) and (b); Data Sheets 5A (Section 2.4), 9A (Section 2.4),19A (Sections 1.2 and 3.1), 20A (Sec-tions 3.0 - 3.4), 21A (Sections 2.0 - 2.2), 22A, 23A (Sections
.
1.0 - 1.1, 6.2, and 8.2) and 24A (Sections 4.0 - 4.2).
During the performance of the simulated failure of Auxiliary Trans-former 1B, the Static Auto Transfer Switch associated with the lA Inverter, which was lined up to the back-up regulated a-c power system for this test, failed to transfer the ICS and NNI loads to the lA Inverter during the loss of power.
Therefore, these loads were lost for approximately 10 seconds until Diesel Generator lA started and powered the Engineered Safeguards Control Center lA.

The cause of the switch failure was being investigated by cognizant licensee representatives.
Resolution of this problem and test data review will be accomplished during a subsequent R0 inspection.
On December 28, 1973 the inspector reviewed the of ficial field copy of TP 600/20 which had been completed and documentation contained in this procedure was discussed with a cognizant licensee represen-tative.
The inspector observed that each deficiency identified in
-
j (1) and (2) above had been corrected.
Additionally, the inspector i
reviewed a memo, dated December 27, 1973, from the GPU Test Superin-l tendent to GPU Test personnel which discussed these deficiencies and stressed the importance and requirements for adherence to ad-ministrative procedures. The inspector was informed that a cognizant engineer had been assigned to review (on a daily basis) test pro-
-
cedures as they are performed to insure documentation requirements are being met and problems are promptly identified.
During the
.
i inspector's review of TP 600/28 (Refer to Paragraph 7.a. above),
he observed the assigned cognizant engineer performing this function.
