DETAILS 1.

Person Contacted Principal Licensee Employees

'

  • K. W. Hunt, Reactor Engineer
  • F. W. Polaski, Reactor Engineer
  • W. T. Ullrich, Station-Superintendent The inspector also contacted other licensee employees during'the inspection,

-including operators, health physics technicians, and support personnel.

  • denotes those present at the exit meeting.

2.

Fuel Pin Puncturing Test a.

The inspector reviewed the special test program and procedures to verify that:

Procedures and changes were reviewed and approved in conformanc'

--

with the Station Administrative Control Procedures.

Procedure centents and instructions were technically adequate,

--

and included sufficient details and provisivas, such as:

prerequisites, precautions, acceptance criteria,. communication between the refueling floor and operations, ventilation and

,

standby gas treatment system, and radiation monitoring.

Special procedures by vendors were reviewed by a station safety

--

review committee.

'

There were no unreviewed safety questions regarding the test

--

program.

b.

The following program, procedures, uocuments and test records were reviewed:

(1) Safety Evaluations The inspector verified that the fuel puncturing tests were conducted during the scheduled refueling outages of 1976, 1978 and 1981 under centractual agreements between the Philadelphia Electric Company (PECo) and the General Electric Company (GE).

Selected fuel pins from Lead Test Assemblies (LTA) ~and Pressurized Test Assemblies (PTA) were punctured under the refueling water

pool on site and the fission gas was retrieved into the sample bottles for analyses.

The objectives of the tests were to obtain accurate fission gas release data and to verify various safety analysis using the isotopic accounting information.

The inspector verified the scopes, objectives, and limitations of the tests via following document review:

--

Correspondence from PECo to GE, April 4, 1978 on 1978 fuel puncturing test.

--

Correspondence from GE to Peach Bottom Atomic Power Station (PB), October 26, 1978 on 1978 fuel puncturing test.

The inspector discussed the fuel pin puncturing tests with the NRR licensing Project Manager and verified that the NRC approved the use of LTA and reconstitution of the test assemblies but was not specifically asked for an approval of the fission gas puncturing program by the licensee.

The inspector determined that there were no unreviewed safety questions regarding this testing progra i

GE FOI No. 137-71067-1, GE PTA LJLTA5 Fuel Inspection and Fuel Rod Fission Gas Retrieval 1981, End of Cycle 4, Revision 0, May 29, 1581.

The testing procedures specified-that the test assembly would be placed in the spent fuel pool and the test fuel pins be

,

punctured using a puncture rig. The fission gas in the exposed

'

pins was retrieved in gas sample bottles, and transported in a shipping cask to a GE laboratory for analysis.

The inspector found that the test program was adequately evaluated in conjunction with the Safety Analysis Report (FSAR).

The inspector did'not find any objective evaluation of potential adverse consequences during the conduct of the tests. The activities related to the specific operations such as disassembly, puncturing and sealing the fuel pins were adequately detailed in each operational procedure. However, the overall program administration and thrs interfaces with the various operational and refueling or testing-groups were not addressed in the test procedures. The following specific items were identified as lacking:

Coordination and communication between various activity

--

groups, i.e., operations, refueling and testing.

--

Test prerequisites and precautions.

Radiation monitoring and protection.

--

Proper documentation and sequencing of the tests.

,

The licensee acknowledged the inspectors findings and subsequently issued a overall test control procedure, FH-46, Fuel Pin Puncturing,.

Inspection and Reconstitution of Fuel Bundles, Revision 0, September 24, 1981.

The inspector also toured the refueling floor and discussed the adequacy of the radiation monitoring and venting systems during the tests with licensee engineers and health physics personnel.

Based on these observations and the documents reviewed as well-as corrective action taken, the inspector determined that the fuel puncturing testing and associated activities would be in conformance with safety requirements. The inspector had no further questions.

3.

, Entrance and Exit Interviews Licensee management was informed c." +he purpose and scope of the inspection at the entrance interview.

Findings of the inspection were periodically discussed with the licensee representatives. The inspector conducted an exit interview with licensee representatives (denoted in paragraph 1) at the conclusion of the inspection on September 18, 1981. The licensee acknowledged the inspection findings.
