w SUPPORTING STATEMENT

- FOR-GENERIC LETTER 81-37 ODYN CODE REANALYSIS REQUIREMENTS A.l.

Justification.

(c)

Bases for Issuance j.

By letter dated November 4, 1980 (enclosed) the NRC informed a class of licensees of a requirement for use of a specific computer

~

code in certain-licensing basis calculations. The code, known as ODYN, _was found by the Staff to provide better best estimate calculation predictions of reactor core response-to pressurization.-

J transients than the code currently in use, called REDY. A schedule -

1 for implementation using ODYN vice REDY in licensing basis calcula-1-

tions for certain future licensing actions (e.g., core reloads) and previously completed transient analyses that employed REDY was provided. The letter also informed licensees that a safety evalua-l tion documenting the basis for the Staff's acceptance of the ODYN code would be forthcoming.

By letter dated January 29,1981 (enclosed) the NRC provided the licensees with safety evaluations. describing its basis for acceptance of the ODYN code, information required for ODYN application, 'and a description of two options (called "A" and "B") for application that were based on known reactor protection system scram response times.-

OMB clearance had not originally been requested by NRC because the action was considered to be only a~ refinement of existing require-ments that simply substituted a better. analytical technique.

Based on subsequent communications between a number of affected licensees and the Staff, it became apparent:that'the less limiting option'(Option B) was applicable for a number of _ facilities.. As a result, it appears reasonable for NRC to take action to provide l

administrative relief from the' schedule provided in the November 4, 1980_ letter. This would result in a substantial reduction in the burden imposed on licensees to perform the required calculationsi j

in accordance with the published schedule.

Accordingly, the Staff proposes to issue the enclosed Generic Letter in order to provide relief to licensees and requests OMB 4

clearance to fulfill the requirements of the Paperwork Reduction Act. The Generic Letter would suspend the required analysis using I

ODYN in certain cases as discussed in the enclosure.

. After submittal by licensees, NRC reviews the plant-specific an.tlyses in accordance with established procedures to assure that the facilities are operated in a manner that protects the public l

health and safety.

l (ii)

Alternative Data Sources Since a plant-specific detailed analysis is required in each case, there is no source for the required infomation other than licensees.

1 (iii)

Use of Similar Data Existing data is being used where possible to reduce the burden on licensees. That is, it has been detennined that existing calculations which used the REDY code are, under certain circum-stances, acceptable. The enclosed Generic Letter would relieve several licensees from performing redundant calculations.

2.

Description of Potential Respondent Universe The Generic Letter will be distributed to 14 licensees (22 units).

In some cases, a utility may hold more than one NRC license.

3.

Tabulation and Publication Plans There are no plans to publish the infomation received from licensees pursuant to these reporting and application requirements.

4.

Time Schedule for Data Collection and Publication This information is provided in the enclosure.

5.

Consultations Outside the Agency a.

The actions in NRC letters dated November 4,1980 and January 29, 1981 and the enclosed proposed Generic Letter have been discussed on an informal basis with the following licensees:

Tennessee Valley Authority

-- Carolina Power and Light Nebraska Public Power District Comonwealth Edison

-- Iowa Electric Power and Light Power Authority of the State of New York Georgia Power Company Northeast Nuclear Energy Company

~

4 j

t Northern States Power Company Niagra Mohawk Power Corporation Jersey Central Power a'nd Light Philadelphia Electric Company Boston Edison Company

-Vermont Yankee Nuclear Power Corporation

~

i b.

Item a. above lists all affected licensees.

c.

As a result of these discussions, at least two licensees have been identified that would be relieved from performing the required i

analyses as a result of issuance of the enclosed Generic Letter.

t d.

Information obtained from the above consultations was used in the development of the enclosed Generic Letter.

e.

Notice to licensees of the proposed action was given to licensees in the November 4,1980 letter.

i f.

No public comment has been received.

6.

Estimate of Compliance Burden t

Each plant-specific analysis using ODYN costs about 1.2 staff-years. Assuming each licensee were to provide 1 plant-specific analysis in accordance with the published schedule, total cost is about 26.4 staff-years.

Issuance of the enclosed Generic i

Letter would result in a known reduction in burden to licensees to at least~ 2.4 staff-years based on information available at this -

time. Using a base of 2,080 hours9.259259e-4 days <br />0.0222 hours <br />1.322751e-4 weeks <br />3.044e-5 months <br /> per staff year. this totals 4,992' staff hours. Total burden for 22 affected licensees is l

109,824 staff hours.

7.

Estimate of' Cost to Federal Government It is estimated that the cost to the Federal Government would be approximately $80,000. This is salary for two GS-14 staff reviewers working full-time for six month-period of time inclusive of overhead l

charges necessary.

ODYN CODE (GENERIC LETTER 81-08)

By letter dated November 4,1980, we informed you of our requirements for use of the ODYN code to calculate pressurization transients, and stated that a safety evaluation describing the basis for our acceptance of this code would be mailed to you in the near future.

Enclosed you will find a safety evaluation and a supplemental safety evalu-ation which jointly evaluate the ODYN code and provide information required for application of ODYN.

As you were informed in our letter of November 4,1980, transient analyses performed by General Electric supporting reload submittals received after February 1,1981, must contain appropriate ODYN analyses in place of those previously performed with REDY for the limiting transients. After January 1982, all operating BWRs with General Electric analyses must have the limiting transients recalculated with the ODYN code, even if no reload submittal has been received.

Also, this requirement for the calculation of the limiting transients with the ODYN code.is applicable to applicants for an operating license and is a prerequisite to obtaining an operating license.

TO ALL HOLDERS OF CONSTPUCTION PERMITS AND OPERATING LICENSES FOR B0ILING WATER REACTORS The use of the ODYN code to e 11culate pressurization transients has been reviewed extensively b1 the staff and discussed with the General Electric Company.

We have found that ODYN.provides acceptable best estimate calculation predictions of the core responses to pressurization transients.

A safety evaluation describing the basis for this conclusion will be mailed to you in the very near future.

This letter is for the purpose of advising you as early as possible of our require-ments for implementation of ODYN for licensing basis calculations performed by the General Electric Company. These requirements are ap'plicable to license applications and all proposed license amendments, including core reloads for which analyses are provided by General Electric.

Transient analyses performed by General Electric supporting reload submittals received prior to February 1,1981, will be reviewed taking into account the results of recent generic transient, analyses with ODYN., Appropriate CPR penalties will be applied on a case by case basis.

Transient analyses performed by General Electric supporting reload submittals received after February 1,1981, must contain l

appropriate ODYN analyses in place of those previously performed with REDY for the limiting transients.

Generally, these will include generator load rejection /ourbine trip without bypass (whichever is limiting), feedwater controller failure - maximum demand, and main steamline isolation valve closure (to satisfy ASME code pressure requi rements).

After January 1982, all operating BWRs with General Electric analyses mus-have the limiting transients recalculated with the ODYN code, even if no reload submittal has been received. The transients analyzed with ODYN most be justified to be the limiting transients.

General Electric has provided an ODYN analysis for the two most limiting events for BWR 3 and BNR 4 plant types and has conmitted to provide analyses for a BWR 2 plant type by November 1,1980. Any 6

r-c.

2-November 4, 1980

~

penalties resulting from our review of the analyses for any plant type will be applied to all plants of that type until plant-specific calculations have been perfomed with ODYN for the two most limiting transients.

Sincerely,
