REQUEST FOR ADDITIONAL INFORMATION UPGRADED METEOROLOGICAL PROGRAM ENCLOSURE l

  • Since the Salem SER was written (October 1974)~ NUREG-0654, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants 11 has been issued.. A de-scription of and completion schedule for an upgraded meteorological program in subs tan ti.a 1.- compliance with NUREG-0654, Appendix 2 is required by NUREG-
0694, 11TMI-Related Requirements for New Operating Licenses 11 before issuance of a full power license.

The essentiaLelements of the NUREG-0654, Appendix 2 criteria are:

1.

A primary* meteorological measurements program with redundant power sources.

2.

A backup meteorological measurements program with redundant power sources..

3.

A system for making real-time predictions of the atmospheric effluent transport* and diffusion, including Class A and Class B models as de-scribed.. in Appendix 2.

4.

A capability for remote interrogation on demand of the atmospheric measurements and prediction systems by the licensee, emergency response organizations, and the NRC staff with primary and backup communications systems.

The presently.available Salem Emergency Plan, submitted July 12, 1980, provides ve.ry limited information on the emergency meteorology pr.ogram which is not responsive to the requirements in NUREG-0694 for a full power license.

We require that PSE&G commit to incorporating these essential elements in their emergency meteorological program and provide a completion schedule for each element.

Enclol.e 2 REQUEST FOR INFORMATION RELATED TO TURBINE DISCS I.

For each indication detected, provide details of the location of the crack, its orientation, and size.

III. Indicate discs that will have sufficient moisture in the hub to cause a pro-pensity for stress corrosion cracking..

IV. *Indicate whether an analysis and evaluation regarding turbine missiles has been perfonned for your plant and provida:i to the staff. If such an anaTYsis and evaluation has been perfonned and reported, please provide appropriate references to the available documentation.

In the event that such a study has been made, consideration s-hotJld. be gtven to schedultng such an action.

ENCLOSURE 3 REQUEST FOR ADDITIONAL INFORMATION CONTAINMENT PRESSURE BOUNDARY FRACTURE TOUGHNESS We require the following information:

1.

Identification of the fabrication codes (edition and addenda) and the specific* paragraphs in these codes that specify the fracture toughness requirements and acceptance criteria (for weldments and base metals).

Codes and code paragraphs should be identified for all materials which constitute part of the containment pressure boundary (e.g., free stand-ing ves-sel, piping penetrations, personnel airlocks, equipment hatch);

2.

The materials test data that certify that the fracture toughness acceptance standards have been met for each of the identified materials in the containment pressure boundary;

3.

The containment lowest service metal temperature;

4.

As built,dimensi.ons and material of construction of the penetration sleeve and canopy seal welded to the process pipe and sleeve as shown in your FSAR, Figure 5.2-38.

REQUEST FOR ADDITIONAL INFORMATION CLADDING SWELLING AND RUPTURE MODELS ENCLOSURE 4

= -T>te'NRC staff-has been generically evaluating three materials models that

  • are used in ECCS evalua~ions. Those models predict cladding rupture temperature, cladding burst strain, and fuel assembly flow blockage, We have (a) discussed our evaluation with vendors and other fodustry repre-sentatives (Reference 1), (b) published NUREG-0630, "Cladding Swelling and Rupture Models for LOCA Analysis" (~ference 2), and (c) required licensees to confirm that their operating reactors would continue to be in conformance with 10 CFR 50.46 if the NUREG-0630 models were substituted for the present materials models in their ECCS evaluatfons and certain other _compensatory model changes were allowed (References 3" and 4).

Until we have c_ompleted our generic review and implemented new acceptance criteria for cladding models, we will require that the ECCS analyses in your FSAR be accompanied by supplemental c13lculations to be performed with the materials models of NUREG-0630.

For these supplemental calculations only, we will accept other compensatory model changes that may not yet be approved by the NRC, but are consistent with the changes allowed for the confirmatory operating reactor calculations mentioned above.

Please provide the supplemental calculations described above.

ENCLOSURE 5 REQUEST FOR ADDITIONAL INFORMATION

. RELIEF AND SAFETY VALVE TEST REQUIREMENTS

1.

PSE&G should conmit to monitor the EPRI program to provide assurance that:

(a)

(b) it will be applicable to the Salem plant design, and

.. it will provide sufficient information to qualify Salem's reactor coolant system relief and safety valves and associated pip!ing and supports under expected operating conditions for

2.

PSE&G should cominit to submit to NRC by July 1, 1981 the following information with respect to Salem:

(a).

Evidence supported by test of safety and relief valve function-ability for expected operating and acctdent (non-ATWS} condi-tions.

The testing should demonstrate that the valves will open and reclose under the expected flow conditions.

(b)

Since it is not planned to test all valves on all plants, PSE&G must $.Ubm.it a correlation, or other evidence, to subs tan ti ate that the valves tested in thefliPRol*program*:demonstrate function-ability of as-installed primary relief and safety valves.*

Thfs correlation must show that the test conditions used are eq~ivalent to expected operating and accident conditions as prescribed in the FSAR. *The effect of as-built relief and safety valve discharge piping on valve operability must also be accounted for, if it is different than the generic test loop piping.

le}

Test data i.ncluding criteria for success and failure of valves tested.must be provided for review and evaluation. This test data should include data which would permit plant specific evaluation of discharge piping and supports which are not tested* directly.

3.

PSE&G sh.cul d commit to submit Ely January l, 1982 evidence supported 5.y tes~* to qualify Salem~s block valves under expected operating conditions for design 5asis transients and accidents.
