NRC letter, dated April 15,1997; SUBJECT: Three Mile Island-Unit 1,

Design inspection (NRC Inspection Report No. 50-289/96-201)

NRC letter, dated March 20,1997; SUBJECT: NRC Integrated

Inspection Report Nos. 50-289/97-01 and 50-320/97-01

Dear Mr. Langenbach:

i

1

Based on review of findings (unresolved items) contained in reference 1, we have identified-

seven apparent violations associated with Technical Specifications 3.3.1 and 3.6.6,

10 CFR 50.59,10 CFR 50.71(e), and 10 CFR Part 50, Appendix B (Criteria Ill, V_ and XVI),

as described in enclosure 1. Enclosure 1 identifies the area (s) of concern and the

reference 1 report section (and item number) that are related to specific regulatory

requirements.

!

Reference 2 contained four apparent violations associated with Technical Specifications

j

6.5.1.2,10 CFR 50.59 and 10 CFR Part 50,' Appendix B, (Criteria V and XV!), as described

in enclosure 2. Enclosure 2 identifies the area (s) of concern and the reference 2 report

sections that are related to specific regulatory requirements.

The apparent violations are being considered for escalated enforcement action in

accordance with the " General Statement of Policy and Procedure for NRC Enforcement

Actions" (Enforcement Policy), NUREG-1600. No Notice of Violation is presently being

issued for these inspection findings. In addition, please be advised that the number and

characterization of apparent violations described in enclosures 1 and 2 may change as a

-i

result of further NRC review.

,

!

A predecisional enforcement conference lo discuss these apparent violations has been

.

scheduled for May 22,1997. The decician to hold a predecisional enforcement conference

l

does not mean that the NRC has determined th::hese violations have occurred or that

enforcement action wi1 be taken. This conference is being held to obtain information to

enable the NRC to make an enforcement decision, such as a common understanding of the

facts, root causes, missed opportunities to identify the apparent violations sooner,

corrective actions, significance of the issues and the need for lasting and effective

corrective action.

At the conference, we expect your presenta? ion to address, but not be limited to, the

following issues associated with the apparent violations:

i

i

(1)

design control weaknesses in the peformance of calculations and in the

i

control of calculations used in the analysis for switchover of the decay heat

removal system (DHRS) pump suction from the borated water storage tank

'

(BWST) to the reactor building sump under post-accideat conditions;

(2)

calculations that were being performed in documents, such as memoranda,

technical data reports, and plant engineering evaluation requests, that do not

comply with your engineering procedures for calculations;

(3)

nonconservative assumptions and missing inputs in calculations for the

makeup pumps and makeup tank;

(4)

a potential unreviewed safety question when evaluating a Final Safety

Analysis Report (FSAR) change regarding the net positive suction head for

the DHRS pumps; and

(5)

untimely and ineffective actions relative to dispositioning of licensee

identified deficiencies associated with the Quality Classifiestion List.

The conference provides an opportunity for you to point out any errors in our inspection

report and for you to provide any information concerning your perspectives on: 1) the

severity of the violations, 2) the application of the factors that the NRC considers when it

determines the amount of a civil penalty that may be assessed in accordance with Section

VI.B.2 of the Enforcement Policy, and 3) any other application of the Enforcement Policy to

this case, including the exercise of discretion in accordance with Section Vll. This

conference will be open to public observation,

You will be advised by separate correspondence of the results of our deliberations on this

matter. No response regarding these apparent violations is required at this time. In

,

accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and

I

its enclosure will be placed in the NRC Public Document Room,
